Answer:
A
Step-by-step explanation:
The volume (V) of a cylinder is calculated as
V = πr²h ( r is the base radius and h the height )
Here r = 6 and h = 8, then
V = π × 6² × 8 = π × 36 × 8 = 288π cm³ → A
First is to know length and width of the rectangular garden.
length of the garden is difference in the x coordinates
L = 8 - 2 = 6 ft
while the width is the difference in the y coordinates
w = 5 - 3 = 2 ft
now we can solve the area of the rectangular garden.
A = Lw
A = 6 x 2 = 12 sq ft
Cost = ($ 5.25 / 6 sq ft) x ( 12 sq ft)
cost = $ 10.5

Answer:
Option d
Step-by-step explanation:
We need 2 fundamental data to solve this problem.
1.- Average number of clients attended in 1 hour.
2.- Time in which it is expected that a client will be attended.
They tell us that the average number of clients served in an hour is m = 8
They tell us to calculate the probability that the client will be seen in less than 15 minutes.
But the time t in the formula is given in hours.
Therefore we must write 15 minutes according to hours.
We know that
.
So:
.
Now we substitute in the formula
and
to find P.
![P = 1 -e^{-mt}\\\\P = 1- e^{-(8)(0.25)}\\\\P = 1 - e^{-2}\\\\P = 0.8646\\\\P= 86\%](https://tex.z-dn.net/?f=P%20%3D%201%20-e%5E%7B-mt%7D%5C%5C%5C%5CP%20%3D%201-%20e%5E%7B-%288%29%280.25%29%7D%5C%5C%5C%5CP%20%3D%201%20-%20e%5E%7B-2%7D%5C%5C%5C%5CP%20%3D%200.8646%5C%5C%5C%5CP%3D%2086%5C%25)
