The relative frequency of the class interval 65-75 is .20.
<h2>What is relative frequency?</h2>
The word 'relative' is used to indicate that an event is being considered in relation or in proportion to something else.
Frequency is a way to measure how often a particular event occurs. Relative frequency, on the other hand, is a way to measure how often a particular event occurs against total occurrences.
Given that: 50 participants scored between 65 and 75 on a test.
Hence,
The relative frequency of the class interval 65-75 = 75 - 65 = 20

Answer:
radius r = 5 ft r=d/2
height h = 3 ft
volume V = 235.619449 ft3³ or 235.36 A is your answer.
lateral surface area L = 94.2477796 ft²
top surface area T = 78.5398163 ft²
base surface area B = 78.5398163 ft²
total surface area A = 251.327412 ft²
In Terms of Pi π
volume V = 75 π ft³
lateral surface area L = 30 π ft²
top surface area T = 25 π ft²
base surface area B = 25 π ft²
total surface area A = 80 π ft²
Step-by-step explanation:
Calculate volume of a cylinder:
V = πr²h
Calculate the lateral surface area of a cylinder (just the curved outside)**:
L = 2πrh
Calculate the top and bottom surface area of a cylinder (2 circles):
T = B = πr²
Total surface area of a closed cylinder is:
A = L + T + B = 2πrh + 2(πr²) = 2πr(h+r)
Agenfa: r = radius
h = height
V = volume
L = lateral surface area
T = top surface area
B = base surface area
A = total surface area
π = pi = 3.1415926535898

Let's use our largest amount (quarter) to see how many can fit evenly into 1.74.
- 1.74/0.25 = 6.96
- The most quarters that can fit into $1.74 is 6.
---Multiply $0.25 by 6 = $1.50
---Subtract $1.50 from $1.74 = $0.24
---We need to use the rest of the coins to fill up $0.24.
Now let's use our second largest amount (dime) to see how many can fit evenly into 0.24.
- 0.24/0.10 = 2.4
- The most dimes that can fit into $0.24 is 2.
---Multiply $0.10 by 2 = $0.20
---Subtract $0.20 from $0.24 = $0.04
No nickels can fit into $0.04, because they are worth $0.05.
We can use our least amount (pennies) to fill in the $0.04 remaining.
Your answer is 6 quarters, 2 dimes, and 4 pennies.

H
Step-by-step explanation:
Area of a square is given as 16 unit²
Since formula of square is
A=l²
16=l²
l=√16
=4
