The answer is 0.50.

P(4<=X<=8)=P(x=4)+ P(x=5)+ P(x=6)+ P(x=7)+ P(x=8)= 0.05+ 0.15+0.15+0.15 +0 = 0.50

Notice that in 8 the line touches the x axis so it’s corresponding probability is 0.

A) y=1/3x+5
B) y=-2x+9
C) y=-3
D) y=2x+9

F) y=x-2

Explanation:
Use y=mx+b

b=starting point (or where it crosses the y-axis

For slope, use rise over run.
To determine negative slope, read from left to right and see if it’s going up or down. If down it’s negative, if up then positive.

Also BE CAREFUL, on D, the y-axis is labeled differently. Take an extra look at it.
