Answer:

7 X 8 = 56

6 X 8 = 48

8 X 8 = 64

8 X 11 = 88

8 X 16 = 128

If the division is left divided goes into the right then it would be:

72 divided by 3 = 24

17 divided by 3 = 5.66666

11 divided by 3 = 3.66666

9 divided by 3 = 3

216 divided by 3 = 72

If the division is right divided goes into the left then it would be:

24 divided by 3 = 8

33 divided by 3 = 11

51 divided by 3 = 51

27 divided by 3 = 9

72 divided by 3 = 24.

Step-by-step explanation:

for the first problem you multiply the left numbers by the 8 to get the right numbers and to get the left numbers you divide the right numbers by 8.

For the second problem if the division is left divided goes into the right then it would be for getting the left numbers multiply the right numbers by 3 and for getting the right numbers just divide the left by 3 but if the division is right divided goes into the left then it would be the exact same process as before but in this one if you are getting the left numbers just divide the right by and if you getting the right numbers then multiply the left numbers by 3.

ps: sorry this answer is long.

Answer:

A. 16%

Step-by-step explanation:

Problems of normally distributed samples can be solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

$\mu = 64, \sigma = 4$
