Hi guys, I'm having trouble with this problem.
Consider a group of 8 people.
a. How many orders are there for these 8 people to stand in a line?
b. How many ways are there to choose a president, a vice president, and a secretary?
c. How many ways are there to choose a group of 3 people from this group?
Thank you for your time!
Answers
B) Answer is 336
Explanation
There are 8 ways for a President to be selected, and have chosen a president there are 7 ways to choose a Vice (from the remaining people). Then, six ways to choose a secretary.
Then, 8*7*6 = 336.
I'm not 100% sure about this as I have used this method for 9 people and two roles, but I'm rather confident the same rules apply.

Key: 2 | 1 | 0 means 12 for Bay Side and 10 for Seaside
Part A: Calculate the measures of center. Show all work. (2 points)
Part B: Calculate the measures of variability. Show all work. (1 point)
Part C: If you are interested in a smaller class size, which school is a better choice for you? Explain your reasoning. (1 point)
PLEASE HELP ASAP !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Answers
Part A: To calculate the measures of center, we can find the median and the mean for each school.
For Bay Side School, the median class size is the average of the 8th and 9th values when the data is sorted in ascending order. The 8th and 9th values are both 25, so the median class size is 25.
To find the mean class size for Bay Side School, we can add up all the class sizes and divide by the total number of classes. The sum of the class sizes is 12 + 12 + 12 + 14 + 15 + 15 + 16 + 16 + 18 + 18 + 20 + 20 + 23 + 25 + 25 = 243. There are 15 classes, so the mean class size is 243/15 ≈ 16.2.
For Seaside School, the median class size is the average of the 8th and 9th values when the data is sorted in ascending order. The 8th and 9th values are both 15, so the median class size is 15.
To find the mean class size for Seaside School, we can add up all the class sizes and divide by the total number of classes. The sum of the class sizes is 10 + 10 + 10 + 11 + 12 + 15 + 15 + 16 + 17 + 17Part A (continued):
18 + 18 + 20 + 20 + 25 = 222. There are 14 classes, so the mean class size is 222/14 ≈ 15.9.
Therefore, the measures of center for Bay Side School are: median = 25, mean ≈ 16.2.
The measures of center for Seaside School are: median = 15, mean ≈ 15.9.
Part B: To calculate the measures of variability, we can find the range and the interquartile range (IQR) for each school.
For Bay Side School, the range is the difference between the largest and smallest class sizes. The largest class size is 25, and the smallest class size is 12, so the range is 25 - 12 = 13.
To find the IQR for Bay Side School, we need to find the first quartile (Q1) and the third quartile (Q3) of the data. From the stem-and-leaf plot, we can see that Q1 is 15 and Q3 is 20. Therefore, the IQR is 20 - 15 = 5.
For Seaside School, the range is the difference between the largest and smallest class sizes. The largest class size is 25, and the smallest class size is 10, so the range is 25 - 10 = 15.
To find the IQRPart B (continued): for Seaside School, we need to find the first quartile (Q1) and the third quartile (Q3) of the data. From the stem-and-leaf plot, we can see that Q1 is 12 and Q3 is 18. Therefore, the IQR is 18 - 12 = 6.
Therefore, the measures of variability for Bay Side School are: range = 13, IQR = 5.
The measures of variability for Seaside School are: range = 15, IQR = 6.
Part C: If you are interested in a smaller class size, Seaside School is a better choice because its measures of center are lower than those of Bay Side School, indicating that its class sizes tend to be smaller on average. Additionally, Seaside School has a smaller range and IQR, indicating less variability in class size. Therefore, there is less chance of encountering very large classes at Seaside School compared to Bay Side School.

Answer: I believe the answer is around/about 56.55
Step-by-step explanation: C=2πr=2·π·9≈ 56.54 or aound 56.52
Formula: C=2πr
Simplified Equation:
2 x 3.14 x 9= 56.52 - 56.55
Good luck!! I hope this helps! All you have to do is memorize the formula, break down & simplify the numbers and equation and you're golden!!
Edit: I reccomend checking out Khan Academy for math help!
Answer:
C= 56.52
Step-by-step explanation:
\(C=\pi d\\\)
\(C=(3.14)(18)\\C=56.52\)
If you didn't understand it in mathmatical terms, then here it is in English.
Step 1:
Re-write the formula (Please don't forget to do this step as it is a VERY important step in math)
Step 2:
Once yoou have re-writen the formula, substitute
In place of \(\pi\) write "3.14"
In place of \(d\) write 18. I got 18 because the diameter is 2r or twice the amount of the radius. So I added 9. So the equation would be \(C=(3.14)*(9+9)\)
\(C=(3.14)*(18)\)
Step 3:
Solve for "C" or Circumfrence
\(C=(3.14)*(18)\\C=56.52\)
I hope it's clear and understandable. :D

edward deposited $7,500 into a savings account 5 years ago. The simple interest rate is 5%. How much money did earn in interest?
Answers
Answer:
Edward earned $1,875 in interest.
Step-by-step explanation:
The formula for simple interest is i = prt, where p is the principal, r is the interest rate as a decimal fraction, and t is the time in years.
Here, p = $7,500, r = 0.05 and t = 5 years, and so the interest earned was
i = ($7,500)(0.05)(5) = $1,875.
Edward earned $1,875 in interest.

A. 37.5%
B. 9.1%
C. 18.2%
D. 12.5%
Answers
Answer:
Step-by-step explanation:
To find the conditional frequency of someone who likes Flip-Frog game and is between 18 and 22 years old, we need to use the formula:
Conditional frequency = (Frequency of Flip-Frog players between 18 and 22) / (Total frequency of Flip-Frog players)
From the table, we see that the frequency of Flip-Frog players between 18 and 22 is 4, and the total frequency of Flip-Frog players is 9+4+12=25.
Therefore, the conditional frequency of someone who likes Flip-Frog game and is between 18 and 22 years old is:
Conditional frequency = 4 / 25 = 0.16 = 16%
Rounding to the nearest tenth, we get:
Conditional frequency = 16.0%

Answer:
x=12.5% (hope this right if not I am so sorry)
Answer Explanation:
let x%= annual interest rate
deposit = $800
interest earning period = 24 months = 24/12 years
interest earned = $200
so $200 = $800 * x /100* 24/12
200 = 800 * x/100 * 2
