Will bought 4 slices of pizza for $6.00. let x represent the number of slices of pizza purchased, and let y represent the total cost. graph the line that represents the proportional relationship.

The graph of line

Step-by-step explanation:

Since, here x represent the number of slices of pizza purchased, and let y represent the total cost.

And, According to the question,

Will bought 4 slices of pizza for $6.00.

Therefore, the price of one slice pizza = 6/4 = $3/2

Thus, the price of x pizza = 3x/2

But, the price of x pizza = y

Therefore, y = 3x/2

Which is the required equation of line.

And, this line passes through the origin.

If x =2 y =3

If x= 4 y = 6

If x = 8 , y= 12

Thus, the points of the line are ( 2,3), (4,6) and (8,12)

Therefore, we can plot the graph of the line with help of above information.

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0
