The switchboard in a small denver law office gets an average of 6 incoming phone calls during the noon hour on thursdays. staffing is reduced accordingly; people are allowed to go out for lunch in rotation. experience shows that the assigned levels are adequate to handle a high of 8 calls during that hour. (a) what is the chance that at least 10 calls are received in the noon hour, some particular thursday, and thus missing important calls?

answer

see attachment

explanation

the given function is

this function has y-intercept at

-4 and a slope of 2.

note that, the graph has a positive slope.

the graph that represents this function is the straight line that moves upward from left to right.

the graph touches the y-axis at -4.

the correct choice is the graph shown in the attachment.

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

i suppose it should be (y=2x-5)
