Answer:
do 49 x 49 which equals 2,401 then check it
put 2,401 square root which equals 49
The answer would be 53,562. You would multiply 47400 by 1.13 to get your answer. Hope this helps!

Answer:
32 km/h
Step-by-step explanation:
Since there are 60 minutes in an hour, we can find their speed in km/h by multiplying the current distance by 2:
16(2)
= 32
This means the bicyclist can ride 32 km in 1 hour.
So, their speed is 32 km/h
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
