Answer:
For a continuous random variable X, P(20 ≤ X ≤ 40) = 0.15 and P(X > 40) = 0.16.
Step-by-step explanation:
Here, P(x > 40) = 0.16
a). P(x < 40) = 1 - P(x > 40)
= 1 - 0.16
= 0.84
b). P(x < 20) = 1 - 
= 1 - {P(20 ≤ X ≤ 40) + P(X > 40)}
= 1 - (0.15 + 0.16 )
= 1 - 0.31
= 0. 69
c). P(x = 40) = 0; The probability that a continuous variable assume a particular value is zero.
125 would be the correct answer unless you needed to round then it would be 126

Answer:
9(3+5)
Step-by-step explanation:
GCF is 9, because thats the highest <u>common</u> number that both numbers can be divided by.
27/9 = 3
45/9 = 5
so,
9(3+5)
Answer:
81
Step-by-step explanation: 9 * 9 = -81 * -1 = 81
