Answer:

b = -2

Step-by-step explanation:

-5(5b+7)=7b+29

Distribute

-25b -35 = 7b +29

Add 25b to each side

-25b+25b-35 =7b+25b+29

-35 = 32b+29

Subtract 29 from each side

-35-29 = 32b+29-29

-64 = 32b

Divide each side by 32

-64/32 = 32b/32

-2 =b

Step-by-step explanation:

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