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 - ![P(x\geq 20)](https://tex.z-dn.net/?f=P%28x%5Cgeq%2020%29)
= 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.
Answer:
![P=19,000(1.034)^{t}](https://tex.z-dn.net/?f=P%3D19%2C000%281.034%29%5E%7Bt%7D)
Step-by-step explanation:
Let
P-------> the population of Jacksonville
t----> the number of years since 2018
we know that
The equation that models the population of Jacksonville in t years is
![P=19,000(1+r)^{t}](https://tex.z-dn.net/?f=P%3D19%2C000%281%2Br%29%5E%7Bt%7D)
we have
![r=3.4\%=3.4/100=0.034](https://tex.z-dn.net/?f=r%3D3.4%5C%25%3D3.4%2F100%3D0.034)
substitute
![P=19,000(1+0.034)^{t}](https://tex.z-dn.net/?f=P%3D19%2C000%281%2B0.034%29%5E%7Bt%7D)
![P=19,000(1.034)^{t}](https://tex.z-dn.net/?f=P%3D19%2C000%281.034%29%5E%7Bt%7D)
