The scores on a psychology exam were normally distributed with a mean of 56 and a standard deviation of 5. About what percentage of scores were less than 46. The percentage of scores that were less than 46 was ?

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

the answer is 0.8in^2

hope you get it down chief.

the answer is $23.63
