Answer:
Angular speed of the towers top about its base is [tex]6.91\times 10^{-13}[/tex] rad per sec.
Step-by-step explanation:
Linear velocity of leaning bell tower 'v' = 1.2 mm per year
v = [tex]\frac{1.2\times 10^{-3}}{365\times 24\times 60\times 60}[/tex]
v = 3.8 × [tex]10^{-11}[/tex] meter per second
Height of the tower = 55 meter
From the formula of angular velocity,
v = rω
ω = [tex]\frac{v}{r}[/tex]
ω = [tex]\frac{3.8\times 10^{-11}}{55}[/tex]
ω = [tex]6.91\times 10^{-13}[/tex] rad per second.
Therefore, top of the tower is moving with an angular speed of [tex]6.91\times 10^{-13}[/tex] rad per second.
Three red balls, 4 white balls, and 1 green ball are in a bag. A ball is drawn without replacement. What is the probability that 3 balls can be drawn without drawing the green ball?
Answer:
[tex]\frac{5}{8}[/tex]
Step-by-step explanation:
Three red balls, 4 white balls, and 1 green ball are in a bag. A ball is drawn without replacement.
total balls = 3 red + 4 white + 1 green = 8 balls
the number of balls that are not green is 7
pick 3 balls from 7 balls that are not green
[tex]nCr= \frac{n!}{r!(n-r)!}[/tex]
[tex]P(not \ green)=\frac{7C3}{8C3}[/tex]
[tex]7C3= \frac{7!}{3!(7-3)!}=35[/tex]
[tex]8C3= \frac{8!}{3!(8-3)!} =56[/tex]
[tex]P(3 \ balls \ drawn)=\frac{35}{56} =\frac{5}{8}[/tex]
In a mid-size company, the distribution of the number of phone calls answered each day by each of the 12 receptionists is bell-shaped and has a mean of 37 and a standard deviation of 9. Using the empirical rule (as presented in the book), what is the approximate percentage of daily phone calls numbering between 28 and 46?
Answer:
0.6826
Step-by-step explanation:
Mean(μ) = 37
Standard deviation (σ) = 9
P(28 < x < 46) = ???
Using normal distribution
Z = (x - μ)/σ
For x = 28
Z = (28 - 37)/9
Z = -9/9
Z = -1
For x = 46
Z = (46 - 37)/9
Z = 9/9
Z = 1
We now have
P(-1 < Z < 1)
= P(Z < 1) - P(Z < -1)
From the table, Z = 1 = 0.3413
φ(Z) = 0.3413
Recall that
When Z is positive, P(x<a) = 0.5 +φ(Z)
P(Z<1)= 0.5 + 0.3413
= 0.8413
When Z is negative, P(x<a) = 0.5 - φ(Z)
P(Z< -1)= 0.5 - 0.3413
= 0.1587
We now have
0.8413 - 0.1587
= 0.6826

One store has 3 Managers and 12 Salespeople.Another store has 4 Managaers and 15 salespeople. Do both stores have equivalent ratios of managers to salespeople explain.
Answer:
The ratio of mangers to sales people of the stores are not equivalent as the ratios in their simplest form are not equal.
Step-by-step explanation:
Given:
One store has:
3 Managers and 12 sales persons
Another store has:
4 Managers and 15 sales persons.
To find if the ratio of mangers to sales people are equivalent.
Solution:
Store A:
Managers = 3
Sales people = 12
Ratio of mangers to sales people for store A = [tex]\frac{3}{12}[/tex] =[tex]\frac{3\div3}{12\div 3}=\frac{1}{4}[/tex] (Simplest ratio)
Store B:
Managers = 4
Sales people = 15
Ratio of mangers to sales people for store B = [tex]\frac{4}{15}[/tex]
The ratio is in the simplest form and cannot be reduced further.
We can see that : [tex]\frac{1}{4}\neq \frac{4}{15}[/tex]
Hence, the ratio of mangers to sales people of the stores are not equivalent.
Traditions clothing store is having a sale. Shirts that were regularly priced at $20 are on sale $17. Explain how to find the discount offered for the price of the shirts?
Answer:
Step-by-step explanation:
Let x represent the discount in percentage offered for the price of the shirts.
The regular price of the shirts was $20
The price for which the shirt was offered for sale is $17 which also represents the discounted price.
The discount would be
20 - 17 = $3
The percentage discount would be
The discount/ the regular price × 100%.
Therefore,
% discount = 3/20 × 100 = 0.15 × 100
= 15%
Jacob and Ali want to run from one corner of a football field to the opposite corner. The rectangular football field is 50 yards wide and 120 yards long. Jacob runs around the perimeter of the field, while Ali runs in a straight line through the middle of the field. How many more yards does Jacob run than Ali?
Answer:
Jacob ran 40 yards more than Ali.
Step-by-step explanation:
Football field is in the shape of a rectangle having dimensions 120 yards × 50 yards
Since Jacob runs around the perimeter of the field from one corner to other corner, therefore, distance run by Jacob = [tex](\text{Length+width})[/tex]
Distance run by Jacob = 50 + 120 = 170 yards
Ali runs through the middle of the field diagonally on a straight line.
Therefore, distance covered by Ali = [tex]\sqrt{\text{length}^{2}+\text{width}^{2}}[/tex]
= [tex]\sqrt{(50)^{2}+(120)^{2}}[/tex]
= [tex]\sqrt{2500+14400}[/tex]
= [tex]\sqrt{16900}[/tex]
= 130 yards
Now difference between the distance covered by Jacob and Ali
= 170 - 130
= 40 yards
Therefore, Jacob ran 40 yards more than Ali.

A: When using polynomial long division, the same process of divide, multiply, and bring down applies, just like when dividing integers.
A: When using polynomial long division, the multiply, subtract, and bring down portion applies just like when dividing integers.
B: When using polynomial long division, polynomial terms are added, not subtracted like in integer division.
A: When using polynomial long division, the same process of divide, multiply, subtract, bring down applies, just like when dividing integers.
B: Polynomial long division uses powers of variables instead of place values used when dividing integers, and only the first term of the divisor is considered in the divide step.
B: Polynomial long division treats remainders differently than they are treated in integer long division.
B: Polynomial long division and integer division are completely the same.
Answer:
A: When using polynomial long division, the multiply, subtract, and bring down portion applies just like when dividing integers
B: Polynomial long division uses powers of variables instead of place values used when dividing integers, and only the first term of the divisor is considered in the divide step
Step-by-step explanation:
The above answers are pretty self-explanatory.
I find polynomial division easier, because the "trial division" step uses only the highest-degree terms, so always gives the exact result you need for the quotient. (There's no "guess and check" as with integer long division.) Powers of the variable take the place of powers of 10 (or whatever number base you're using) in integer long division.
__
For integer long division, the steps are ...
Divide the leading portion of the dividend by the divisor to determine the quotient digit.Multiply the divisor by the quotient digit and subtract the result from the dividend, paying attention to place value. If the quotient digit is too large (the difference is negative), choose a smaller value and repeat.Append the next succeeding digit of the dividend to the difference from the above step to form the new dividend and repeat from the first step until the desired quotient precision is achieved.If all given digits of the dividend have been exhausted, append zero to form the new dividend.Any remainder can be expressed as a fraction with the divisor as its denominator. (That fraction is added to the rest of the quotient.)For polynomial long division, the steps are similar.
Divide the highest degree term of the dividend by the highest-degree term of the divisor to form the next term of the quotient.Multiply the quotient term just found by the divisor and subtract the result from the dividend to obtain the new dividend.Repeat from the first step until the degree of the dividend is less than that of the divisor. If this remainder is non-zero, it can be expressed as a fraction with the divisor as its denominator. (That fraction is added to the rest of the quotient.)_____

Packages of batteries normally sell for $4.99. They are now 20% off. How much would you have to pay?
Answer:
You will have to pay $ 3.99 for the package of batteries with 20% discount
Step-by-step explanation:
Standard price of the batteries packages = $ 4.99
Discount = 20% = 0.2
Discounted price = Standard price - Discount
Discounted price = 4.99 - (0.2 * 4.99)
Discounted price = 4.99 - 1.00 (Rounding to the next tenth)
Discounted price = 3.99
You will have to pay $ 3.99 for the package of batteries with 20% discount
Final answer:
A package of batteries with a 20% discount off the original price of $4.99 would be approximately $3.99 after subtracting the discount amount, which is $0.998.
Explanation:
To calculate how much the student would have to pay for packages of batteries that normally sell for $4.99 with a 20% discount, we first need to determine the amount of the discount. To find the discount amount, multiply the original price by the discount percentage:
$4.99 × 0.20 = $0.998
Now, subtract the discount amount from the original price to get the sale price:
$4.99 - $0.998 = $3.992
The discounted price will be approximately $3.99, as the final amount is traditionally rounded to the nearest cent.
Aparty rental company has chairs and tables for rent. The total cost to rent 5 chairs and 6 tables is $65. The total cost to
rent 3 chairs and 2 tables is $25. What is the cost to rent each chair and each table?
Answer:the cost of renting each chair is $2.5
the cost of renting each table is $8.75
Step-by-step explanation:
Let x represent the cost of renting each chair.
Let y represent the cost of renting each table.
The total cost to rent 5 chairs and 6 tables is $65. This means that
5x + 6y = 65 - - -- - - - - - - -1
The total cost to rent 3 chairs and 2 tables is $25. This means that
3x + 2y = 25 - - - - - - - - - - - -2
Multiplying equation 1 by 3 and equation 2 by 5, it becomes
15x + 18y = 195
15x + 10y = 125
Subtracting, it becomes
8y = 70
y = 70/8 = 8.75
Substituting y = 8.75 into equation 1, it becomes
5x + 6 × 8.75 = 65
5x + 52.5 = 65
5x = 65 - 52.5 = 12.5
x = 12.5/5 = 2.5
The rodriguez brother buys f boxes of frozen burger meat, each containing m slices of meat. Every week, the family eats b burgers. Write an equation in terms of f, m,, and b that represents the number of remaining burger meat,r, after 5 weeks
Answer:
[tex]r=f\times m-5b[/tex]
Step-by-step explanation:
Given:
Number of boxes of burger meat = [tex]f[/tex]
Number of slices of meat in each box = [tex]m[/tex]
Number of burgers the family eats each week = [tex]b[/tex]
Number of burger meat remaining = [tex]r[/tex]
To write: An equation in terms of [tex]f, m,\ and\ b[/tex] that represents the number of remaining burger meat, [tex]r[/tex], after 5 weeks.
Now, since each box contain 'm' slices.
Therefore, by unitary method, number of slices of meat in 'f' boxes is given as:
[tex]Total\ number\ of\ slices=f\times m[/tex]
Now, each week burger consumption = 'b'
So, 'b' slices of meat are eaten each week. Again by unitary method, the number of slices eaten in 5 weeks is given as:
[tex]\textrm{Number of slices eaten in 5 weeks}=5b[/tex]
Now, Slices remaining = Total number of slices - Number of slices eaten in 5 weeks.
Therefore, [tex]r=f\times m-5b[/tex]
Hence, the equation that represents the number of slices of burger meat remaining in terms of 'f', 'm', and 'b' is given as:
[tex]r=f\times m-5b[/tex]
A relationship between two variables in which the variables vary in the opposite direction (i.e., one increases while the other decreases, or vice versa) is referred to as a:________ a) strongerb) weakerc) positived) negative
Answer: d) negative
Step-by-step explanation:
The term correlation is used to define the relationship between the two variables .
We say there is a positive relationship between them if one increases / decreases then other also increases / decreases simultaneously.Here, the variables vary in the same direction.
If one variable increases while the other decreases , then we call it a negative relationship between them.Here, the variables vary in the opposite direction.
∴ A relationship between two variables in which the variables vary in the opposite direction (i.e., one increases while the other decreases, or vice versa) is referred to as a: negative correlation.
Hence, the correct answer is d) negative

In a school, 3/4 of the students study a language. Of those who study a language, 3/5 study French. Find the ratio of students who study French to students who do not study French. Give your answer in its simplest form.
Answer: 9:11
Step-by-step explanation:
Let x be the total number of students.
If 3/4 of students study a language That mean 3x/4 students study a language.
Number of students that don't study a language becomes
x - 3x/4 = x/4.
and 3/5 of those who study language study French, that means 3x/4 * 3/5 of students study French.
This gives 3x/4 * 3/5 = 9x/20 Studying French.
Number of students that study language but do not study French becomes
3x/4 - 9x/20 = 6x/20
Total number of students that do not study French becomes
[total number of students not studying any language] + [total number of students studying a language but do not study French ]
Which becomes
x/4 + 6x/20 = 11x/20
Hence ratio of those that study French to those that do not study French Becomes
9x/20 : 11x/20

Imagine that the interest rate on your savings account was 1% per year and inflation was 2% per year. After 1 year, how much would you be able to buy with the money in this account?
a. More than today
b. Exactly the same
c. Less than today
d. I do not know
Answer:
C Less than today
Step-by-step explanation:
If i save $100 at 1% per annum after 1 year I will get $101, but with inflation rate of 2%per annum a commodity that is worth $100 now will be worth $102 after 1 year so u can't buy same commodity I can buy today after 1 year even when my money has increase.
The purchasing power of money in a savings account would decrease after 1 year due to inflation.
Explanation:To calculate how much you would be able to buy after 1 year, we need to consider the effect of both the interest rate and inflation. With an interest rate of 1% per year, your savings account would increase by 1% over 1 year. However, with an inflation rate of 2% per year, the price of goods and services would also increase by 2% over the same period.
This means that the purchasing power of your money would decrease. To calculate the actual increase or decrease in purchasing power, you can subtract the inflation rate from the interest rate. In this case, 1% - 2% = -1%.
Therefore, the correct answer is c. Less than today. After 1 year, you would be able to buy less with the money in your savings account.

A wheel on carmen's bike is 1.1 m in diameter. Carmen races the bicycle for 93m. How many times dose the wheel turn as the bicycle travels this distance
93÷1.1= 84.545454545
Answer:approximately 30 times
Step-by-step explanation:
The wheel on Carmen's bike circular in shape and has a diameter of 1.1 meter.
Radius = diameter/2 = 1.1/2 = 0.55 meter.
When the wheel completes one revolution, the distance covered is equal to the circumference of the wheel.
The formula for determining the circumference of the wheel is expressed as
Circumference = 2πr
Where π is a constant whose value is 3.14
Circumference = 2 × 3.14 × 0.55 = 3.454 metres.
Carmen races the bicycle for 93m. Therefore, the number of times that the wheel of the bicycle turns as it travels this distance would be
93 / 3.454 = 26.9 times
Suppose that the number of worker-hours required to distribute new telephone books to x% of the households in a certain rural community is given by the function W(x)=250x/(400−x). (a) What is the domain of the function W? (Give the domain in interval notation. If the answer includes more than one interval write the intervals separated by the "union" symbol, U.) (b) For what values of x does W(x) have a practical interpretation in this context? (c) How many worker-hours were required to distribute new telephone books to the first 70% of the households? (d) How many worker-hours were required to distribute new telephone books to the entire community? (e) What percentage of the households in the community had received new telephone books by the time 3 worker-hours had been expended?
Answer:
a) Domain = [tex](-\infty,400)\cup (400,\infty)[/tex]
b) [tex]x \in [0,100][/tex]
c) 53.03 worker hours
d) 83.33 worker hours
e) 83.33 worker hours
Step-by-step explanation:
We are given the following in the question:
[tex]W(x) = \dfrac{250x}{(400-x)}[/tex]
where W(x) is the number of worker-hours required to distribute new telephone books to x% of the households in a certain rural community.
a) Domain of function.
The domain is the all the possible values of x that the function can take.
Domain = [tex](-\infty,400)\cup (400,\infty)[/tex]
b) Values of x
Since x is a percentage in reference to context, it can only take value upto 100. Also it cannot take any negative value.
So domain n reference to context will be
[tex]x \in [0,100][/tex]
c) worker-hours were required to distribute new telephone books to the first 70% of the households
[tex]W(70) = \dfrac{250(70)}{(400-70)} = 53.03[/tex]
53.03 worker hours were required to distribute new telephone books to the first 70% of the households.
d) Worker hour for entire community
For entire community, x = 100
[tex]W(100) = \dfrac{250(100)}{(400-100)} = 83.33[/tex]
83.33 worker hours were required to distribute new telephone books to the entire households.
e) Percentage of the households in the community for 3 worker hours
[tex]3 = \dfrac{250x}{(400-x)}\\\\1200-3x = 250x\\253x = 1200\\\\x = \dfrac{1200}{253} = 4.74\%[/tex]
Thus, 4.74% of the households in the community had received new telephone books by the time 3 worker-hours had been expended.
Final answer:
The domain of the function W(x) is (-∞, 400) U (400, +∞). The values of x that have a practical interpretation in this context are in the interval [0, 100]. Approximately 53.03 worker-hours were required to distribute new telephone books to the first 70% of households, and approximately 83.33 worker-hours were required to distribute to the entire community. After 3 worker-hours, approximately 4.73% of the households had received new telephone books.
Explanation:
(a) The domain of the function W is the set of all possible values of x that make the function defined and meaningful. In this case, the function W(x) is defined except when the denominator 400-x is equal to zero. So, we need to find the values of x that make the denominator zero.
To do that, we solve the equation 400-x = 0, which gives x = 400.
Therefore, the domain of the function W is the set of all real numbers except x = 400. We can express this in interval notation as (-∞, 400) U (400, +∞).
(b) In this context, the function W(x) represents the number of worker-hours required to distribute new telephone books to x% of the households in the rural community. A practical interpretation is only meaningful when x represents a valid percentage, meaning that it is between 0% and 100%, inclusive. So, the values of x that have a practical interpretation in this context are in the interval [0, 100].
(c) To find the worker-hours required to distribute new telephone books to the first 70% of households, we substitute x = 70 into the function W(x). Evaluating the expression, we get: W(70) = 250(70) / (400 - 70) = 17500 / 330 = 53.03.
Therefore, approximately 53.03 worker-hours were required to distribute new telephone books to the first 70% of households.
(d) To find the worker-hours required to distribute new telephone books to the entire community, we substitute x = 100 into the function W(x). Evaluating the expression, we get: W(100) = 250(100) / (400 - 100) = 25000 / 300 = 83.33.
Therefore, approximately 83.33 worker-hours were required to distribute new telephone books to the entire community.
(e) To find the percentage of households that had received new telephone books after 3 worker-hours, we rearrange the function W(x) to solve for x. We have:
W(x) = 250x / (400 - x)
3 = 250x / (400 - x)
3(400 - x) = 250x
1200 - 3x = 250x
1200 = 253x
x = 1200 / 253 ≈ 4.73
Therefore, approximately 4.73% of the households in the community had received new telephone books after 3 worker-hours.

Tell which measure of central tendency best describes the data. Time spent on Internet (min/day): 75 38 43 120 65 48 52 A. Mean B. Median C. Mode
Answer:
B. Median
Step-by-step explanation:
We have been given data about time spent on Internet (min/day). We are asked to determine the best measure of central tendency for the given data.
Data: 75, 38, 43, 120, 65, 48, 52,
We can see that our given data has a very large value outlier (120), so it will increase the mean.
There is no mode for the given data set as no value repeats.
We know that median is best measure for data set with large valued outliers because median is not affected by outliers.
Therefore, option B is the correct choice.
The measure of central tendency that best describes the data is B. Median.
Which measure of central tendency best describes the data on time spent on the Internet?Mean:
= (75 + 38 + 43 + 120 + 65 + 48 + 52) / 7
= 69.86
Median:
We arrange data in ascending order: 38, 43, 48, 52, 65, 75, 120. Since there are seven values, the median is the middle value: 52
Mode: There is no value that appears more than once in the data set.
Therefore, the measure of central tendency that best describes the data is B. Median.

What is Statistics?Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.
To calculate the 4-day SMA (Simple Moving Average)
We need to add up the closing prices for the last 4 days and divide the sum by 4.
We then move the window one day forward and repeat the process.
Using the given closing prices, we can calculate the 4-day SMA as follows:
Day 1: (56 + 61 + 50 + 57) / 4 = 56
Day 2: (61 + 50 + 57 + 60) / 4 = 57
Day 3: (50 + 57 + 60 + 58) / 4 = 56.25
Day 4: (57 + 60 + 58 + 57) / 4 = 58
The 4-day SMA for the given closing prices is: $56, $57, $56.25, $58.
Hence, $56, $57, $56.25 is the 4-day SMA for the following closing prices: $56, $61, $50, $57, $60, $58, and $57.

Jennifer made 5 Liters of punch for her party. Her brother made another 750 milliliters if they combine the two batches how many 180 milliliters servings would they have would there be any punch left over if so how much
Answer:
Step-by-step explanation:
The total amount of punch that Jennifer made for her party is 5 Liters. Her brother made another 750 milliliters.
1000 milliliters = 1 liter
750 milliliters = 750/1000 = 0.75Liter
if they combine the two batches, the total amount made would be
5 + 0.75 = 5.75Liter
= 5.75 × 1000 = 5750 milliliters
The number of 180 milliliters servings would be
5750/180 = 31 servings
There would be leftovers of 170 milliliters

Sue has $40,000 in her savings account. She use some of the money to put towards a house. She has $36,479 left. How much did she put towards the house. Solve and write an equation with a variable to represent the unknown.
Answer:
x = $3,521
Step-by-step explanation:
let the amount of money that she put towards a house be represented by the variable x
Hence,
total savings = amount put towards house + amount left
$40,000 = x + $36,479 (rearrange)
x + $36,479 = $40,000 (subtract $36,479 from both sides)
x = $40,000 - $36,479
x = $3,521
