A telephone call arrived at a switchboard at random within a one-minute interval. The switch board was fully busy for 40 seconds into this one-minute period. What is the probability that the call arrived when the switchboard was not fully busy

step-by-step explanation:

it will be a cylinder. with a diameter of 8 and 4 single pieces high

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

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol

d.) 48 units
