The average performance rating of the employees at company a is 6.5 on a scale from 1 to 10 (10 being highest). the standard deviation is 2.1 the average performance rating of the employees at company c is 7.4. company c has a standard deviation of 6.8. it would be better to hire a random employee from company a.

  the correct choice is marked

step-by-step explanation:

the first two graphs show multiple turning points. the last graphs matches the description in every detail.

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
