Answer:
75.4 square inches
Step-by-step explanation:
The cylindrical block has a height of 4 inches and a radius of 2 inches find the total surface area of the block
The formula for the Total surface area of a cylinder
= 2πr (r + h)
= 2 × π × 2( 2 + 4)
= 75.398223686 square inches
= 75.4 square inches
The total surface area of the cylindrical block is 75.4 square inches.
The number of members that prefers geometry are 54members
Given the total number of people in the math club = 120 members
Let algebra + arithmetic + geometry = 100%
20 + 35 + geometry = 100
55 + geometry = 100
geometry = 100 - 55
geometry = 45%
This shows that the percentage of the member of the club that prefers geometry is 45%
Number of member that prefer geometry = 45% * 120
Number of members that prefer geometry 0.45 * 120
Number of members that prefers geometry = 54 members
Hence the number of members that prefers geometry are 54members

Answer:
22%
Step-by-step explanation:
x/100 * 160=35
160x=3500
21.875
hence to the nearest percent: 22%
16 or more books sold in a day will include two intervals from the given table:
a) 16 - 20 books sold.
Probability = 0.201
b) 21 - 25 books sold.
Probability = ?
Since the table gives the probability distribution, the sum of all the probabilities must be equal to 1. We are given the probabilities of 4 out 5 intervals. So in order to find the probability of the 5th interval (21-25) we can subtract the sum of probabilities of rest of the intervals from 1.
So, P(21 - 25) = 0.019
In order to find the probability of 16 or more books sold we need to sum the probabilities of both these intervals.
So, the probability of 16 or more books being sold on a given day = 0.201 + 0.019 = 0.220
