Answer:

The answer is 60.11

Step-by-step explanation:

An adult person receives 425 pieces of mail each year with a standard deviation of 50.

Now, we have the following details  :

Mean of sample = 425

sigma = 50

Standard error = \frac{425}{\sqrt{50} }

= \frac{425}{7.07} = 60.11

A circle has a circumference of 50.24 units.<br> What is the radius of the circle?
S_A_V [24]

2 \times \pi \times r = 50.24 \\ 2 \times  \frac{22}{7} r = 50.24 \\ r =  \frac{50.24 \times 7}{22 \times 2 }  \\ r =  \frac{351.68}{44}  \\ r = 7.99
