Answer:
13. It is a paralellogram, because its opposite sides are equal & parallel
14. It is a paralellogram , because it's two diagonals bisect each other .
15. Is a paralellogram, cause its opposite angles are equal
Step-by-step explanation:
Answer: A. Mean of sampling means 
Standard deviation of sampling means =
B. The probability that your sample has mean less than 165 is 0.1492 .
Given : The distribution of blood cholesterol level in the
population of young men aged 20 to 34 years is close to normal with
mean
Mg/dl and standard deviation
mg/dl.
Sample size : n= 150
Let
sample mean values.
A. The mean and the standard deviation of the distribution of the sampling means would be :
Mean of sampling means =
Standard deviation of sampling means = 

The probability that your sample has mean less than 165 would be

Hence , the probability that your sample has mean less than 165 is 0.1492 .
Answer: For question 2 I think it would be C
Step-by-step explanation:
The match up are:
- 64 inches : cross-section, cube, 16 inches
- 26 inches : right rectangular prism, 10x 3 x 14 inches
- 48 inches : cube with 12-inches edges
- 34 inches : rectangular prism, 5x12x4 diagonal of 13 inches
<h3>What is a prism?</h3>
A prism is known to be a kind of 3-dimensional shape that has two similar shapes that are known to be facing each other.
Note that:
Right rectangular prism == 10x 3 x 14 inches
Since the cross-section is known to be parallel to the base, then:
P = 10 + 3 + 10 + 3
= 26 inches
For cube that has 12-inches edges
We say that;
P = 12 + 12+ 12 + 12
= 48 inches
For rectangular prism that has 5x12x4 diagonal of 13 inches
We say that:
P = 13 + 4 + 13 + 4
= 34 inches
For cross-section cube that 16 inches,
we say that:
P = 16 + 16 + 16 + 16
= 64 inches.
