Answer:
Number 7 is 34.56in
Step-by-step explanation:
First: Label each side Ex: Left side:
Top:
Bottom:
etc.
Second: Find the area of each side
Third: add them together
P.S. since this was a perfect cube, you could've also just found the area of 1 side then multiplied by 6:)
Divide both sides by 4
e^(2.7x) = 8.25
Take natural logarithm of both sides
2.7x = ln 8.25
x = (ln 8.25)/2.7 = ln (8.25^(1/2.7))
Answer:
h = 18.88 inches
Step-by-step explanation:
Given that,
The circumference of a cylinder is 20 inches
The volume of the cylinder, V = 600 cubic inches
We need to find the height of the cylinder. We know that the volume of a cylinder is given by :
r is radius
We know that,
circumference = 2πr
So,
So, the height of the cylinder is 18.88 inches.
Answer:
y=38 °
Step-by-step explanation:
Answer:
Step-by-step explanation:
a. #We notice this is a Poisson probability function expressed as:
x-number of occurrences in a given interval.
-mean occurrences of the event
-The mean is calculated as:
#the probability of no accidents in a 15-minute period is :
Hence, the probability of no accident in a 15-min period is
b. The the probability of at least one accident in a 15-minute period. is calculated as:
Hence, the probability of at least one accident in a 15-minute period is
c. The probability of four or more accidents in a 15-minute period is calculated as:
Hence,the probability of four or more accidents in a 15-minute period. is 0.9997
