8 0

Answer:

Step-by-step explanation:

Sum = 6

Product = 8

Factors = 2 , 4

x² + 6x + 8 = x² + 2x + 4x + 8

= x(x + 2) + 4(x + 2)

= (x + 2)(x + 4)

Nadusha1986 [10]

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 $s = \frac{\sigma}{\sqrt{n}}$
