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

X is directly proportional with the square root of Y. If X=128 and Y=16 find: X when Y=36 B) Y when X=48 ( HELP ASAP!)
Tems11 [23]

x = sqrt{y}k

K is the constant of proportionality.

128 = sqrt{16}k

128 = 4k

128/4 = k

32 = k

x = sqrt{y}k

x = sqrt{36}•32

x = 6 • 32

x = 192

Find y when x = 48.

x = sqrt{y}k

48 = sqrt{y}32

48/32 = sqrt{y}

(48/32)^2 = [sqrt{y}]^2

2.25 = y
