Answer:
a. 0.5
b. 0.4375
c. 0.125
d. 0
e. 1
f. 0.9655
Solving
Step-by-step explanation:

for -1 ≤ x ≤ 1
a.
probability of P(0<X)


when we integrate we have
![1.5[x^{2+1} ]/3](https://tex.z-dn.net/?f=1.5%5Bx%5E%7B2%2B1%7D%20%5D%2F3)

b. probability of 0.5<x<1


c. probability of p(-0.5≤X≤0.5)
I had difficulty using the math editor. ALmost ran out of time. please check the attachment for the solution to this.
the answer is 1/8 = 0.125
d. probability of x<-2 is equal to 0
e. p(x<0 or X>-0.5)
= p(X>-0.5) + p(x<0.5)
= 1-0.0625 + 0.0625
= 0.9375 + 0.0625
= 1
f.
we are to solve for P(x<X) = 0.05
= 0.9655

For 8, 15.25*18=274.5, 274.5/2= 137.25 or 137 1/4
for 9, 11*13=143, 143/2= 71.5 or 71 1/2
Answer:
4/10 but simplified = 2/5
Step-by-step explanation:
Add the marbles up, there are 4 green, so it's 4/10
But if you simplify it, it would be 2/5
I hope this helped!
THIS IS EASY. I don't have a calculator on me so bare with me.
1.) 7x - 9 = -4x + 90
7x +9. = -4x. + 9
7x. = -4x. 99
+4x = +4x. + 99
11× = 99
÷ 11. ÷ 11
X = 9
U can solve the rest. Are you serious?
