Answer: the average weight of the remaining 2 non-blue items is 81 pounds
Step-by-step explanation:
The formula for determining average is expressed as
Average = sum of each item/ total number of items
Let x represent the average weight of the remaining 2 non-blue items.
The average weight of 5 items is 24 pounds. If the total weight of 3 blue items is 39 pounds, it means that
(x + 39)/5 = 24
x + 39 = 5 × 24 = 120
x = 120 - 39
x = 81

A machine is designed to dispense at least 12 ounces of a beverage into a bottle. To test whether the machine is working properly, a random sample of 50 bottles was selected and the mean number of ounces for the 50 bottles was computed. A test of the hypotheses H0 : μ = 12 versus HA : μ < 12 was conducted, where μ represents the population mean number of ounces of the beverage dispensed by the machine. The p-value for the test was 0.08. Which of the following is the most appropriate conclusion to draw at the significance level of α = 0.05 ?
a. Because the p-value is greater than the significance level, there is not convincing evidence that the population mean number of ounces dispensed into a bottle is less than 12 ounces.
b. Because the p-value is greater than the significance level, there is convincing evidence that the population mean number of ounces dispensed into a bottle is less than 12 ounces.
c. Because the p-value is greater than the significance level, there is convincing evidence that the population mean number of ounces dispensed into a bottle is 12 ounces.
d. Because the p-value is less than the significance level, there is convincing evidence that the population mean number of ounces dispensed into a bottle is 12 ounces.
Answer:
Option c) Because the p-value is greater than the significance level, there is convincing evidence that the population mean number of ounces dispensed into a bottle is 12 ounces.
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 12 ounces
Sample size, n = 50
Alpha, α = 0.05
First, we design the null and the alternate hypothesis
[tex]H_{0}: \mu = 12\\H_A: \mu < 12[/tex]
We use one-tailed test to perform this hypothesis.
P-value = 0.08
Since the p value is greater than the significance level, we fail to reject the null hypothesis and accept it.
Thus, the machine is working properly and dispense 12 ounces of a beverage into a bottle.
Option c) Because the p-value is greater than the significance level, there is convincing evidence that the population mean number of ounces dispensed into a bottle is 12 ounces.
Since the p-value found is more than the level of significance, thus in such case, we can't reject the null hypothesis, and thus accept it.
Thus:
"Option C): c. Because the p-value is greater than the significance level, there is convincing evidence that the population mean number of ounces dispensed into a bottle is 12 ounces.
Given that:
Proposed mean of population = [tex]\mu_0 = 12[/tex]Real population mean (unknown parameter) = [tex]\mu[/tex]Size of sample = [tex]n = 50[/tex]Null Hypothesis = [tex]H_0 : \mu = 12 = \mu_0[/tex]Alternate Hypothesis = [tex]H_A: \mu < 12 = \mu_0[/tex]p-value found = 0.08Level of significance = [tex]\alpha = 0.05[/tex]How to form the hypotheses and test them?Since the p-value found is more than the level of significance, thus in such case, we can't reject the null hypothesis, and thus accept it.
Null hypothesis is the favored hypothesis which we test. The test's result just tells whether the null hypothesis is acceptable or not. The alternative hypothesis is accepted when the null hypothesis is rejected, else we accept the null hypothesis.
Thus, [tex]H_0 : \mu = 12 = \mu_0[/tex] is accepted as [tex]\text{p-value} = 0.08 > 0.05 = \alpha[/tex] and we deduce that:
"Option C: Because the p-value is greater than the significance level, there is convincing evidence that the population mean number of ounces dispensed into a bottle is 12 ounces."
is correct option.

A factory produces toy dolls at the rate of 400 per hour and has to recycle 3% of them because the clothes are torn. Express the recycle percent as a rate per 100
Answer:
The recycle percent as a rate per 100 is 0.03 per hour.
And 12 dolls are recycled each hour during production.
Step-by-step explanation:
The question is incomplete so below is the complete question:
A factory produces toy dolls at a rate of 400 per hour and has to recycle 3% of them because the clothes are torn. Express the recycle percent as a rate per 100. How many dolls are recycled each hour during production?
Now, to express the recycle percent as a rate per 100, And to find the number of dolls are recycled each hour during production.
Number of dolls factory produces at rate per hour = 400.
Percent of recycle = 3%.
So, to express the recycle percent as a rate per 100:
[tex]3\%\ per\ 100[/tex]
[tex]=\frac{3}{100} \ per\ hour[/tex]
[tex]=0.03\ per\ hour.[/tex]
So, to get the number of dolls are recycled each hour during production:
3% of number of dolls factory produces at rate per hour.
[tex]=\frac{3}{100} \times 400[/tex]
[tex]=0.03\times 400[/tex]
[tex]=12.[/tex]
The dolls are recycled each hour = 12.
Therefore, the recycle percent as a rate per 100 is 0.03 per hour.
And 12 dolls are recycled each hour during production.
A man invests his savings in two accounts, one paying 6% and the other paying 10% simple interest per year. He puts twice as much in the lower-yielding account because it is less risky. His annual interest is $3872 dollars. How much did he invest at each rate? Your answer is: Amount invested at 6% equals $ Amount invested at 10% equals $
Answer:
Amount invested at 6% equals $35200; Amount invested at 10% equals $17600
Step-by-step explanation:
For simple interest; A = P (1 + rt), where;
A= final amount, P=principal , r = rate , t = time in years
Let the amount invested in the 6% yielding account be 'x' and the amount invested in the 10% yielding account be 'y'.
From the question, the man invests twice as much in the lower yielding, Therefore;
⇒ x = 2y
Interest = A - P = Prt
Total interest = (Interest for 6% yielding account) + (Interest for 6% yielding account)
⇒ 3872 = ( [tex]x[/tex] X 0.06 x 1) + ( [tex]y[/tex] X 0.10 x 1)
⇒ 3872 = (2[tex]y[/tex] x 0.06 x 1) + ([tex]y[/tex] x 0.10 x 1)
⇒ 3872 = 0.12[tex]y[/tex] + 0.10[tex]y[/tex]
⇒ y = $17600
⇒ x = 2y = $ 35200
Answer: Amount invested at 6% equals $35200
Amount invested at 10% equals $17600
Step-by-step explanation:
Let x represent the amount invested at 6%.
Let y represent the amount invested at 10%.
He puts twice as much in the lower-yielding account because it is less risky. This means that
x = 2y
The formula for determining simple interest is expressed as
I = PRT/100
Where
P represents the principal
R represents the rate of investment
T represents the time in years.
Considering the amount invested at 6%,
I = (x × 6 × 1)/100 = 0.06x
Considering the amount invested at 10%,
I = (y × 10 × 1)/100 = 0.1y
If his annual interest is $3872, it means that
0.06x + 0.1y = 3872 - - - - - - - - - - - -1
Substituting x = 2y into equation 1, it becomes
0.06 × 2y + 0.1y = 3872
0.12y + 0.1y = 3872
0.22y = 3872
y = 3872/0.22
y = 17600
x = 2y = 2 × 17600
x = 35200
Mauricio, a project manager at a reputed firm, has been assigned to handle a new project that the firm has received. This project involves a lot of scheduling that has to be handled by Mauricio. Mauricio estimates that the first module of the project could be completed in as few as 15 days or could take as many as 25 days, but most likely will require 20 days. Determine the expected task duration.
Answer:
20 days
Step-by-step explanation:
Expected Task duration
= (O + 4 M + P)/6
Where O = best case scenario = 15 days
P = worst case scenario = 25 days
M = Usual scenario = 20 days
Therefore, expected task duration
= [15 + 4 (20) + 25] ÷ 6
= 120 ÷ 6
= 20 days.
Therefore expected task duration is 20 days.

Manny is an online student who currently owns an older car that is fully paid for. He drives, on average, 110 miles per week to commute to work. With gas prices currently at $2.65 per gallon, he is considering buying a more fuel-efficient car, and wants to know if it would be a good financial decision. The old car Manny owns currently gets 16 miles per gallon for average fuel efficiency. It has been a great vehicle, but with its age, it needs repairs and maintenance that average $740 per year (as long as nothing serious goes wrong). The newer, more fuel-efficient car that he is looking at to purchase will cost a total of $6,500 over a three-year loan process. This car gets 28 miles per gallon and would only require an average of $10 per month for general maintenance. To help make a decision, Manny wants to calculate the total cost for each scenario over three years. He decides to use the quantitative reasoning process to do this.
In this exercise we have to use the knowledge of finance to identify the best cost benefit is to buy a new car or a used car, thus we find that:
The new car costs more, that can be prove if;
Old car: [tex]\$5062.125[/tex] New car: [tex]\$7161.357[/tex]

Carrie earned $3673 from a summer job and put it in a savings account that earns 10% interest compounded annually. When Carrie started college, she had $7614 in the account which she used to pay her tuition. How long was the money in the account?
Answer:
Step-by-step explanation:
We would apply the formula for determining compound interest which is expressed as
A = P(1+r/n)^nt
Where
A = total amount in the account at the end of t years
r represents the interest rate.
n represents the periodic interval at which it was compounded.
P represents the principal or initial amount deposited
From the information given,
A = 7614
r = 10% = 10/100 = 0.1
n = 1 because it was compounded once in a year.
P = 3673
Therefore,
7614 = 3673(1+0.1/1)^1 × t
7614/3673 = 1.01^t
2.073 = 1.01^t
Taking log of both sides, it becomes
Log 2.073 = log 1.01^t
0.3166 = t × 0.0043
t = 0.3166/0.0043
t = 73.3

(number of remaining students)
Juniors Seniors
Condition
Initially J S15 seniors left S - 15Twice juniors as seniors 2(S - 15)3/4 of the juniors left 1/4×2(S - 15)1/3 of seniors left 2/3×(S - 15)At the end, there were 8 more seniors than juniors:
2/3×(S - 15) - 1/4×2(S - 15) = 8Now you have obtained one equation, which you can solve to find S, the number of senior students, and then the number of junior students.
Solve the equation:
[tex]2/3\times (S - 15) - 1/4\times 2(S - 15) = 8[/tex]
Mutilply all by 12:[tex]8(S - 15)-6(S - 15)=96[/tex]
Distribution property:[tex]8S-120-6S-90=96[/tex]
Addtion property of equalities:[tex]8S-6S=96+120+90[/tex]
Add like terms:[tex]2S=306[/tex]
Division property of equalities:[tex]S=306/2=153[/tex]
That is the number of senior students that came out to the information meeting, but the number of students remaining to perform in the school musical is (from the table above):
[tex]2/3\times (S-15)+1/4\times 2(S-15)[/tex]
Just substitute S with 153 fo find the number of students that remained to perfom in the musical:

At the end of January of last year, stock A was selling at A dollars a share, and stock B was selling a B dollars a share, where A > B. Between January and June, stock A rose x%, and stock B rose y%, where y > x. Suppose a certain investor owned N shares of A, but at the end of January last year, sold those shares and used all of that money to buy shares of B, and held those shares through the end of June. These are the only stocks in this portfolio. Do not mark more than one answer in each column.
Answer: a) yNA/100
b) NA(y-x)/100
c) (NA)/B
Step-by-step explanation:
a) The total amount of dollars owned by the shares' owner = N number of shares × A dollars per share = NA dollars
This total is then transferred to buy B shares which then appreciates by y%.
The amount of increase in portfolio from January to June = y% of total dollars invested = y% of NA dollars = yNA/100
b) If the shares were left with A, the increase in portfolio from January to June would be x% and = x% of the total Dollar amount = x% of NA dollars = xNA/100
How much more money made in that time would be the difference in interest, between taking the dollars to invest in share B or keeping the dollars on investment A
That is, (yNA/100) - (xNA/100) = NA(y-x)/100
c) Total dollars available after sale of the A stock = NA
Number of B stock this dollar can buy = Total dollars available/amount of B stock per share
That is, (NA)/B
QED!
Scientific research on popular beverages consisted of 70 studies that were fully sponsored by the food industry, and 30 studies that were conducted with no corporate ties. Of those that were fully sponsored by the food industry, 15 % of the participants found the products unfavorable, 23 % were neutral, and 62 % found the products favorable. Of those that had no industry funding, 38 % found the products unfavorable, 16 % were neutral, and 46 % found the products favorable.a. What is the probability that a participant selected at random found the products favorable?
b. If a randomly selected participant found the product favorable, what is the probability that the study was sponsored by the food industry?
c. If a randomly selected participant found the product unfavorable, what is the probability that the study had no industry funding?
Answer:
a. 0.26
b. 0.7
c. 0.38
Step-by-step explanation:
For a)
For sponsored studies: 62 % found the products favorable. The percentage is 0.62.
For non-sponsored studies 46% found the products favorable. The percentage is 0.46
Total probability = P(A) × P (B)
= 0.46 × 0.62
= 0.2604
For b)
Probability for the food industry = 0.7
For c) 1 - ( 0.62) = 0.38
The overall probability that a participant finds the product favorable is 57.2%. If the product was found favorable, the probability the study was industry-sponsored is 75.8%. If the product was found unfavorable, the probability the study was not industry-funded is 71.7%.
Explanation:The first step to answer the given question is understand that this is a problem of conditional probability, related to the concept of favorability or unfavorability towards products based on industry-sponsored studies and non-sponsored studies.
To find the overall probability of a participant finding the product favorable, we add the probabilities of a product being favorable under both industry funding and no industry funding, weighted by their respective chances of occurrence.
Begin by finding probability that industry sponsored and product was favorable: ((70/100) * (62/100) = 0.434)Then find probability that no industry funding and product was favorable: ((30/100) * (46/100) = 0.138)Add these two probabilities together, which gives 0.434 + 0.138 = 0.572, or 57.2%To work out the conditional probabilities:
For an industry sponsored study given that the product was favorable, the probability is ((70/100) * (62/100)) divided by 0.572 = 0.758, or 75.8%For the study having no industry funding given that the product was unfavorable, the probability is ((30/100) * (38/100)) divided by ((70/100)*(15/100) + (30/100)*(38/100)) = 0.717, or 71.7%Learn more about Probability here:https://brainly.com/question/22962752

The larger angle measures
4)The measure of an angle is 1/4 the measure of its complement. Find the measure of each angle.
The smaller angle measures
The larger angle measures
Answer:
Step-by-step explanation:
1) the sum of the angles on a straight line is 180°.
Let x represent the measure of the smaller angle.
The measure of one angle is twice the measure of the other angle. This means that the larger angle is 2x. Therefore,
x + 2x = 180
3x = 180
x = 180/3 = 60
The measure of the smaller angle is 60°
The measure of the larger angle is 2 × 60 = 120°
2) The measure of one angle is 1/3 the measure of the other angle. If the measure of the larger angle is x, then the measure of the smaller angle is x/3. Therefore,
x + x/3 = 180
Multiplying through by 3, it becomes
3x + x = 180 × 3 = 540
4x = 540
x = 540/4 = 135
The smaller angle measures
135/3 = 45°
The larger angle measures 135°
3) the sum of complimentary angles is 180°
The measure of an angle is nine times the measure of its complement. If the measure of the smaller angle is x, then the measure of the larger angle is 9x. Therefore,
x + 9x = 90
10x = 90
x = 90/10 = 9
The smaller angle measures 9°
The larger angle measures 9 × 9 = 81°
4) The measure of an angle is 1/4 the measure of its complement.
If the measure of the larger angle is x, then the measure of the smaller angle is x/4. Therefore,
x/4 + x = 90
Multiplying through by 4, it becomes
x + 4x = 360
5x = 360
x = 360/5 = 72
The smaller angle measures 72/4 = 18°

Answer: the number of people coming to the football game decreased by 13%
Step-by-step explanation:
2300 people came to the football game yesterday and the number of people decreased to 2001. This means that the amount by which the number of people that came for the football game in both days decreased would be
2300 - 2001 = 299
Therefore, the percentage decrease in the number of people coming to the football game would be
299/2300 × 100 = 13%

A jar contains 11 green marbles, 6 red marbles, and 9 blue marbles. A marble is selected at random, not replaced, and then a second marble is selected. What is the probability of selecting a red marble followed by a green marble?
Write In a fraction.
The probability of selecting a red marble and then a green marble, without replacement, is 33/325.
Explanation:The probability in this case is being calculated as the outcome of two independent events - selecting a red marble first and then selecting a green marble. The total number of marbles in the jar is the sum of green, red, and blue marbles which is 11+6+9 = 26.
First, let's calculate the probability of drawing a red marble. There are 6 red marbles out of a total 26 marbles, so the probability is 6/26 (which reduces to 3/13).
Next, the jar now has 25 marbles left, and 11 of them are green. So, our probability of drawing a green marble after a red one is 11/25.
For both events to happen one after the other, we multiply the individual probabilities together. Hence, the combined probability of these two events would be (3/13) * (11/25), which equals 33/325.

The probability of first selecting a red marble and then a green marble from a jar containing 11 green, 6 red, and 9 blue marbles is 33/325.
Explanation:The subject of this question is probability, which is a branch of mathematics. The problem involves calculating the probably of two events occurring in sequence: selecting a red marble and then a green one from a jar of colored marbles. In total there are 26 marbles: 11 green, 6 red, and 9 blue.
The probability of selecting a red marble first is 6/26 as there are 6 red marbles and 26 total marbles in the jar. Once you've chosen a red marble, it's removed from the jar. So for the second event, there are now 25 marbles in the jar, with 11 of them being green. So, the probability of selecting a green marble is 11/25.
The probability of both events (Choosing a red marble then a green one) happening one after the other is the product of the individual probabilities. So, the probability is (6/26) × (11/25) which simplifies to 33/325.

Kylie and Amelia go to the movie theater and purchase refreshments for their friends. Kylie spends a total of $125.50 on 12 bags of popcorn and 7 drinks. Amelia spends a total of $87.50 on 6 bags of popcorn and 8 drinks. Write a system of equations that can be used to find the price of one bag of popcorn and the price of one drink. Using these equations, determine and state the price of a drink, to the nearest cent.
Answer: a drink costs $5.5
Step-by-step explanation:
Let x represent the cost of one bag of popcorn.
Let y represent the cost of one drink.
Kylie spends a total of $125.50 on 12 bags of popcorn and 7 drinks. This means that
12x + 7y = 125.50 - - - - - - - - - - 1
Amelia spends a total of $87.50 on 6 bags of popcorn and 8 drinks. This means that
6x + 8y = 87.50 - - - - - - - - - -- - - 2
Multiplying equation 1 by 1 and equation 2 by 2, it becomes
12x + 7y = 125.50
12x + 16y = 175
Subtracting, it becomes
- 9y = - 49.5
y = - 49.5/ - 9
y = 5.5
Substituting y = 5.5 into equation 2, it becomes
6x + 8 × 5.5 = 87.50
6x + 44 = 87.5
6x = 87.5 - 44 = 43.5
x = 43.5/6 = 7.25
Maggie's mom agrees to let Maggie buy small gifts for some friends. Each gift costs $4. Maggie's mom gave her a budget of $19. When Maggie went online to order gifts, she discovered there was a $7 shipping fee no matter how many gifts she bought.
Answer:
If you`re trying to figure out how many gifts Maggie can get without the fee going over the budget, then I would say that she can buy 3 gifts. 4 times 3 is 12, and when you add 7 it equals 19. Of course, if 3 is pushing it, Maggie can also buy 1 or 2 gifts, and she`d be fine. Hope this helps!

Incomplete question
Complete question: Jaclyn plays singles for South's varsity tennis team. During the match against North, Jaclyn won the sudden death tiebreaker point with a cross-court passing shot. The 57.5-gram ball hit her racket with a northward velocity of 26.7 m/s. Upon impact with her 331-gram racket, the ball rebounded in the exact opposite direction (and along the same general trajectory) with a speed of 29.5 m/s.
a. Determine the pre-collision momentum of the ball.
b. Determine the post-collision momentum of the ball.
c. Determine the momentum change of the ball.
Answer:
A. 1.5353kgm/s
B. 1.6963kgm/s
C. 0.161kgm/s
Step-by-step explanation:
A. The pre-collision momentum of the ball = mass of ball × velocity of ball
Mass of ball = 57.5g = 0.0575kg
Velocity of ball = 26.7m/s
Pre-collision momentum of ball = 0.0575×26.7
= 1.5353kgm/s
B. Post collision momentum of the ball = mass of ball × velocity of ball after impact
Velocity of ball after impact = 29.5m/s
Post collision momentum of ball after impact = 0.0575×29.5
= 1.6963kgm/s
C. Momentum change of ball = momentum after impact - momentum before imlact
= 1.6963kgm/s - 1.5353kgm/s
= 0.161kgm/s

Rectangle ABCD is shown with diagonal AC drawn. Point F is on AC and point E on DC such that FE is perpendicular to DC. Prove triangle ABC is similar to triangle CEF
Triangle ABC is similar to triangle CEF.
Explanation:
Diagram is inserted for the reference.
ABCD is a rectangle.
ABC is a right angled triangle because all the angles of the rectangle are 90◦ - (a)
CEF is a right angled triangle because FE is perpendicular to DC – (b)
In triangles ABC and CEF,
1. Angle ABC = Angle CEF = 90◦ (Both are right angles from a and b)
2. Angle BCA = Angle EFC (Alternate angles on parallel lines are equal on intersection)
Hence using Similarity property of AA (Angle, Angle), Triangle ABC and CEF are similar.
ΔABC and ΔCEF are similar triangles by the AA similarity theorem.
What is the AA Similarity Theorem?The angle-angle similarity theorem (AA) states that when two triangles have two pairs of corresponding congruent angles, both triangles are similar triangles.
In ΔABC and ΔCEF, we have the following:
Two pairs of corresponding congruent angles - ∠FEC ≅ ∠ABC (right angles) and ∠FCE ≅ ∠BAC
Therefore, ΔABC and ΔCEF are similar triangles by the AA similarity theorem.
