Answer:

CD = 6.3

Step-by-step explanation:

The triangles CED and CGF are similar since two sides are on same line and one side is parallel.

<u>Corresponding sides have equal ratios:</u>

CG/CE = CF/CD
CG/CE = (CD - 1.8)/CD
6/(6 + 2.4) = (CD - 1.8)/CD
6/8.4 = (CD - 1.8)/CD
1/1.4 = (CD - 1.8)/CD
1*CD = 1.4CD - 1.4*1.8
0.4CD = 2.52
CD = 2.52/0.4
CD = 6.3

Answer:

By the Central Limit Theorem, the average value for all of the sample means is 14.

Step-by-step explanation:

We use the central limit theorem to solve this question.

The Central Limit Theorem estabilishes that, for a random variable X, with mean $\mu$ and standard deviation $\sigma$ , the sample means of size n can be approximated to a normal distribution with mean $\mu$ and standard deviation, which is also called standard error $s = \frac{\sigma}{\sqrt{n}}$
