Answer:
see below
Step-by-step explanation:
h(t) = -16t^2 + 256
h(4) =0
This means at t=4 second the height above the ground is 0
At 4 seconds, the penny will hit the ground

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.
A fraction between 0 and 1/2
What is smaller than 1/2?
Smaller than 0.5 is 0.3
0.3 = 1/3
A fraction smaller than 1/2 and bigger than 0 is 1/3
Final answer: 1/3
