A set of middle school student heights are normally distributed with a mean of 150 centimeters and a standard deviation of 20 centimeters. Let X = the height of a randomly selected student from this set.
Find P(130 < X < 150).
You may round your answer to two decimal places.

step-by-step explanation:

if u want da anser kill your teeser ifu hav wun

it is not that hard all u have to do is plot the graph

step-by-step explanation:

show da graph

step-by-step explanation:

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x
