Answer:
8.06
Step-by-step explanation:
3.5^2 + 2^2 = 16.25
sqrt(16.25) = 4.03112887
2 * 4.03112887 = 8.06225774

Answer:
A
Step-by-step explanation:
Pick a point on the triangle and move it down until it lines up with its red counterpart. Then move the same point over until it lines up with the red counterpart completely. In conclusion, the answer is (x,y) -> (x+4,y-4) or A
X=1. if 1 to the second power=1 and four times 1=4, 1+4-5=0.
Answer:
a)
Mean 
b)
c)
Step-by-step explanation:
From the given information:
a.)
Mean
Let consider X to be a random variable that follows an exponential distribution; then:
P(X) = 1 - 
since 
b.)
The required probability that a random chosen customer would spend more than $5,000 can be computed as:
![P(X > 5000) = 1 - \bigg [ 1 - e ^{- \dfrac{5000}{1250}} \bigg]](https://tex.z-dn.net/?f=P%28X%20%3E%205000%29%20%3D%201%20%20-%20%5Cbigg%20%5B%201%20-%20e%20%5E%7B-%20%5Cdfrac%7B5000%7D%7B1250%7D%7D%20%20%5Cbigg%5D)
c.)
![P(X > 1250) = 1 - \bigg [ 1 - e ^{- \dfrac{1250}{1250}} \bigg]](https://tex.z-dn.net/?f=P%28X%20%3E%201250%29%20%3D%201%20%20-%20%5Cbigg%20%5B%201%20-%20e%20%5E%7B-%20%5Cdfrac%7B1250%7D%7B1250%7D%7D%20%20%5Cbigg%5D)
