Answer:
Choosing a boy randomly in a class of 10 boys and 10 girls
Step-by-step explanation:
The probability of choosing a boy randomly in a class of 10 boys and 10 girls is calculated as;
(number of boys)/ (total number of students in the class)
= 10/(10+10) = 10/20 = 1/2
The probability of drawing a heart randomly out of a pile of 4 hearts and 8 spades is calculated as;
4/(4+8) = 4/12 = 1/3
The probability of correctly choosing a random number between 1 and 10 is simply 1/10 since the numbers are have a uniform distribution and thus equally likely to be selected.
The probability of choosing a girl randomly in a class of 8 girls and 12 boys is calculated as;
(number of girls)/ (total number of students in the class)
= 8/20 = 2/5
Thus choosing a boy randomly in a class of 10 boys and 10 girls is the event which has a probability closest to 1.
Final answer:
Out of the given events, choosing a boy randomly in a class of 10 boys and 10 girls has the highest probability, which is 0.5. Therefore, this event's probability is closest to 1.
Explanation:
To answer which event has a probability closest to 1, we need to calculate the probability of each event:
Choosing a girl randomly in a class of 8 girls and 12 boys has a probability of
8 girls / (8 girls + 12 boys) = 8/20 = 2/5 or 0.4.
Comparing these probabilities, choosing a boy randomly in a class of 10 boys and 10 girls has the highest probability, which is 0.5. Therefore, this event has a probability closest to 1.

What is the inverse equation of the function, y=5x-4
Answer:
y^-1 = (x + 4)/5
Step-by-step explanation:
To find the inverse equation of the function y=5x - 4, first we need to switch the x and y:
→ y = 5x - 4
→ x = 5y - 4
Now, solving for 'y':
→ x = 5y - 4
→ x + 4 = 5y
→ y = (x + 4)/5
therefore, the inverse equation is: y^-1 = (x + 4)/5

Which linear inequality is represented by the graph
For this case we have that the boundary line of inequality is dotted, therefore equality is not included.
We find the slope of the line, substituting two points that pass through it:
[tex](0,3)\\(3,5)\\m = \frac {5-3} {3-0} = \frac {2} {3}[/tex]
We evaluate a point within the region and see which case is met:

1-5= -44-5= -10-5= -5What is the measure of ced?
Answer:
212°
Step-by-step explanation:
We have the measure of CE and the measure of ED, so all we have to do is combine those two to get the measure of CED.
The arc CE measures 52 degrees.
The arc ED measures 160 degrees
The arc CED is the sum of arc CE and ED, so:
CED = 52° + 160° = 212°
We don't have any length measurement inside that circle to calculate the length of the arc CED in inches, centimeters or otherwise... so we can only measure it degrees.

Sally's $8,800 savings is in two accounts. One account earns 2% annual interest and the other earns 6%. Her total interest for the year is $440. How much does she have in each account?
Answer:
In the 2% account, Sally has $2200 and in the 6% account, Sally has $6600.
Step-by-step explanation:
Suppose the amount invested at 2% is $X and the amount invested at 6% is $Y (assuming that the college student invested all his/her income on the two schemes). Therefore:
X + Y = 8800 (The sum of investments is basically the total income).
0.02X + 0.06Y = 440 (The sum of the interest received from the invested amounts is actually the total return).
Now solving these 2 simultaneous equations:
x + y = 8800 (Equation 1)
2x + 6y = 44000 (Equation 2)
From (Equation 1):
x = 8800 - y (Equation 3)
Put (Equation 3) in (Equation 2):
2(8800 - y) + 6y = 44000.
17600 - 2y + 6y = 44000.
4y = 26400
y = 6600.
To find x, substitute y = 6600 in equation 3. This gives:
x = 8800 - y.
x = 8800 - 6600.
x = 2200.
So in the 2% account, Sally has $2200 and in the 6% account, Sally has $6600!!!

Do 2 ratios form a proportion???
They form a proportion when both of the ratios are equivalent.
An example: 3/15 and 1/5 is a proportion because the are equivalent.
The reason why they are equivalent is because if you cross multiply meaning doing 3*5 which equals 15 and 15*1 which equals 15 so basically you multiply the numerator by the other fractions denominator and do the same for the other side and see if the numbers are the same if they are not the same they are not a proportion if they are the same they are a proportion.
Hope this helps!

yes

Brian received a phone call today asking him to donate to a disaster relief found.
Answer:
Option B
Step-by-step explanation:
It is always wise to ask who or what the organization is asking. Always be safe.
Answer:
I would 100% go with
"Option B. Ask for the name of their organization and look for information about them to make sure they're authentic before he donates"
Step-by-step explanation:
That was the only logical decision, because for D. you can't just hope for the best and donate "blindfolded". A. was really not a smart decision because if you give someone your credit card number, they could easily take all the money they wanted off of it and put you in loads of debt. And then for C., it was the same with D., you can't just donate to an organization or charity fund when you have no idea if it's a probable cause or not. So, in conclusion "Option B." is your best and most logical answer.

which value makes this equation true -4x = 20
Answer:
x= -5 makes the given equation -4x = 20 true
Step-by-step explanation:
We have been given the equation;
-4x = 20
we are to determine the value of x that will make the equation true. We simply make x the subject of the formula;
divide both sides of the equation by -4;
(-4x)/(-4) = 20/(-4)
x = -5
Therefore, x= -5 makes the given equation -4x = 20 true
Answer:
[tex]x=-5[/tex]
Step-by-step explanation:
The given linear equation is:
-4x = 20
To find the value of x that makes the equation true, we need to solve for x.
We divide both sides by -4 to obtain:
[tex]\frac{-4x}{-4}=\frac{20}{-4}[/tex]
This is the sane as:
[tex]\frac{-4x}{-4}=\frac{-5\times-4}{-4}[/tex]
We cancel out the common factors to get:
[tex]x=-5[/tex]

Final answer:
To find the total cost per mile to rent the car, add the rental cost for 5 days to the gasoline cost, then divide by the miles driven. Ruth Barr's total cost per mile was approximately $0.3785.
Explanation:
To calculate the total cost per mile to rent the car, we need to add the cost of renting the car for 5 days to the cost of gasoline and then divide the sum by the number of miles driven.
Calculate the rental cost for 5 days: 5 days × $59.95/day = $299.75.
Add the cost for gasoline: $299.75 (rental cost) + $137.76 (gasoline) = $437.51.
Divide the total cost by the number of miles driven: $437.51 ÷ 1156 miles = approximately $0.3785 per mile.
The total cost per mile Ruth Barr spent to rent the car was approximately $0.3785.
find the given angle to the nearest degree.
Answer:
[tex]\alpha=44\°[/tex]
Step-by-step explanation:
By definition, the tangent of an angle is the quotient between the side opposite the angle and the side adjacent to the angle
In other words:
[tex]tan(\alpha) = \frac{opposite}{adjacent}[/tex]
In this triangle, the length of the side adjacent to the desired angle is 50, and the length of the opposite side is 48
So:
[tex]tan(\alpha) = \frac{48}{50}\\\\tan(\alpha)= 0.96[/tex]
Finally
[tex]\alpha =arctan(0.96)\\\\\alpha=44\°[/tex]
Answer:
Final answer is [tex]?=44[/tex] degree.
Step-by-step explanation:
Using given information in the picture, we need to find the missing value of angle "?"
Apply formula of tangent function which is :
[tex]\tan\left(\theta\right)=\frac{opposite}{adjacent}[/tex]
[tex]\tan\left(?^o\right)=\frac{48}{50}[/tex]
[tex]\tan\left(?^o\right)=0.96[/tex]
[tex]?=\tan^{-1}\left(0.96\right)[/tex] degree
[tex]?=43.830860672092581097187030418859[/tex] degree
Hence final answer is [tex]?=44[/tex] degree.

6. When making adjusting entries, which account is never affected?
A. Capital
B. Withdrawal
C. Fees Expense
D. Cash
It never affects D. Cash
Answer:
Cash is never affected.
Step-by-step explanation:
When making adjusting entries, cash is never impacted.
Adjusting entries means to make the account up to date at the end of the accounting period.
All adjusting entries affect a minimum of one income statement account and one balance sheet account, but this never affects cash.
does this have a. Proportional relationship
No, to be proportional, there would be a consistent pattern between x and y. For example 2 times 2.5 is 5. And 3 times 2 is 6. The ratio is not the same.
If t>0 and t2−25=0, what is the value of t?
Answer:
Final answer is [tex]t=5[/tex].
Step-by-step explanation:
Given equation is [tex]t^2-25=0[/tex].
Now we need to solve that equation for t when [tex]t>0[/tex].
[tex]t^2-25=0[/tex]
[tex]t^2-5^2=0[/tex]
[tex](t+5)(t-5)=0[/tex]
or [tex](t+5)=0[/tex], [tex](t-5)=0[/tex]
or [tex]t+5=0[/tex], [tex]t-5=0[/tex]
or [tex]t=-5[/tex], [tex]t=5[/tex]
Given that t>0
so that means t=-5 is not possible.
Hence final answer is [tex]t=5[/tex].
