Suppose medical records indicate that the length of newborn babies in
inches) is normally distributed with a
mean of 20 and a standard deviation of
2.6. Find the probability that a given
infant is between 17.4 and 22.6 inches
long.

i = 2 / - 5

step-by-step explanation:

evaluation of ( 2 - 4 ) ( p + q ) when p = 2 and q = 5 i, by putting values of p and q,                                                                    

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
