Answer:
11331 non fiction books
Step-by-step explanation:
Given :
Total books = 67982
Childrens section = 1/3 of total
Number of children's books :
(1/3 * 67982) = 22660 books (approximately)
Books left :
67982 - 22660 = 45,322 books
Fiction books:
75% of remaining
0.75 * 45322
33991.5
= 33991 books
If the only section left is non - fiction, then
Non - fiction books = (45322 - 33991) = 11331
Question: What is the MAD of the data set?
13, 6, 3, 7, 11
Your mean would be: 8
But your answer would have to be: 3.2
i am pretty sure the answer is 8.
Answer:
D) Wanda will receive $23.50 for her share, meaning she lost $1.50 on the investment.
Step-by-step explanation:
Identify what you know:
1) Wanda bought a single share in Tasty Ice Cream for $25.00 on March 1st.
2) Tasty Ice Cream's stock price dropped to $23.50 (-1.50).
When investing in the stock market, you are always attempting to make a profit. So, you buy a stock when it's "low," and buy it when the prices go up. In reality, Wanda shouldn't sell her share yet, because she will lose $1.50. However, there is nothing stopping her, if she wanted to. Since the share is worth $23.50, Wanda will make $23.50 if she sells her share on June 13th.

As an aid to the establishment of personnel requirements, the director of a hospital wishes to estimate the mean number of people who are admitted to the emergency room during a 24-hour period. The director randomly selects 64 different 24-hour periods and determines the number of admissions for each. For this sample, X = 396 and S = 100. Using the sample standard deviation as an estimate for the population standard deviation, what size sample should the director choose if she wishes to estimate the mean number of admissions per 24-hour period to within 1 admission with 99% reliability, what size sample should she choose?
Answer:
Sample size n = 16
Step-by-step explanation:
We use the formula for Margin of Error for the question
Margin of Error = z × Standard deviation/√n
Margin of Error = 1
z score for 99% confidence interval = 2.576
Standard deviation = 100
1 = 2.576 × 100/√n
1 × √n = 257.6
√n = 257.6/1
n = √257.6
n = 16.049922118
Approximately = 16
Therefore, the sample size = 16
