Ahandler loads one item every 10 ? minutes, so 48 items are completed in his first day of work. his manager checks his work by randomly selecting an hour of the day, when reviewing all the items he completed that hour. does this sampling plan result in a random? sample

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
