Answer:
16th term = 39.
Step-by-step explanation:
Plug 16 into the formula -6 + 3(n - 1):
A(16) = -6 + 3(16-1)
= - 6 + 3*15
= -6 + 45
= 39.
Answer:
Yes. They are proportional.
Step-by-step explanation:
The left side 0.777 is equal to the right side 0.777, which means that the given statement is always true.
True
Answer:
0.3678
Step-by-step explanation:
Jones figures that the total number of thousands of miles that an auto can be driven before it would need to be junked is an exponential random variable with parameter 1/20. Smith has a used car that he claims has been driven only 10,000 miles. If Jones purchases the car, what is the probability that she would get at least 20,000 additional miles out of it?
Given that the total number of thousands of miles(X) that an auto can be driven
before it would need to be junked is an exponential random variable with parameter 1/20.
=> X ≅ Exponential(λ= 1/20)
=> f(x) = 1/20 * e^(-x/20) , 0 < x < ∞
=> F(X) = P{X < x} = 1 - e^(-x/20)
The probability that she would get at least 20,000 additional miles out of it.
P{X > 20} = 1-P{X < 20}
P{X > 20} = 1-(1 - e^(-20/20))
= e^(-1)
= 0.3678
Answer:
Step-by-step explanation: i rlly dont know dont worry someone will answer it for u!
all i know is the mike had a better deal of gas then Serena
The circumference is doubled since circumference is directly proportional to radius, and the area is quadrupled since it is directly proportional to the radius squared
