Radius of ball is 6 inches. Then the volume is 904.32 
<u>Solution:</u>
Given that, radius of a ball is 6 inches.
We have to find the volume of the ball with 6 inches radius.
Now, we know that, a ball will be in a shape of sphere, so we have to use the volume of a sphere formula to find the volume of the ball.
<em><u>The volume of sphere is given as:</u></em>

where r is the radius.
Here in our problem, r = 6


Hence the volume is 904.32

Answer:
a) P(X ≤ 4) = 0.9
b) P(X>7) = 0
c) P(X ≤ 5) = 0.9
d) P(X>4) = 0.1
e) P(X≤2)= 0.7
Step-by-step explanation:
Hello!
Given the distribution of cumulative probability
0 for X < 1
F(x) 0.7 for 1 ≤ X < 4
0.9 for 4 ≤ X < 7
1 for 7 ≤ X
To determine each of the asked probabilities you have to select the probability corresponding to the defined intervals for X:
a) P(X ≤ 4) = 0.9
This value of X is included the interval "4 ≤ X < 7" so the corresponding probability is 0.9
b) P(X>7) = 0
This is equal to the expression:
1 - P(X≤7)
This expression is included in the last interval so the probability is 1
1 - 1 = 0
c) P(X ≤ 5) = 0.9
5 is included in the third interval "4 ≤ X < 7" so the corresponding probability is 0.9
d) P(X>4) = 0.1
P(X>4) = 1 - P(X≤4)
P(X≤4) is in the interval of definition "4 ≤ X < 7" so the corresponding probability is 0.9
1 - 0.9 = 0.1
e) P(X≤2)= 0.7
The value X=2 is included in the second interval "for 1 ≤ X < 4", so the probability is 0.7
I hope it helps!
