Answer:
0.3 probability that 
Step-by-step explanation:
The probability distribution is given in the table.
Probability that x <= -3
The values that are -3 or lower are -3 and -5. So

From the table:
. So

0.3 probability that 
Answer:
34
Step-by-step explanation:
The interval from x = -4 to x = 0 is when the graph is completely flat.
We can write this interval as -4 < x < 0 which becomes (-4,0) in interval notation
That's why the answer is choice C
Note: be careful not to mix up interval notation and ordered pair notation
Step-by-step explanation:
area of ∆ = .5*b*h
b= x+5
h= x-5/2
let's do (x+5) * (x-5/2)
x^2+5x-5/2x-25/2
x^2+5/2x-25/2
area = .5x^2+5/4x-25/4
