The difference between the greatest and lowest numbers in a piece of data is the range. The range of the given data set {6, 9, 9, 12, 18, 24, 24, 24, 37} is 31.
What is the range?
The difference between the greatest and lowest numbers in a piece of data is the range. The difference here is that the range of a set of data is determined by subtracting the sample maximum and minimum.
The range of the given data set {6, 9, 9, 12, 18, 24, 24, 24, 37} is,
37-6 = 31
Hence, The range of the given data set {6, 9, 9, 12, 18, 24, 24, 24, 37} is 31.

This questions bothers permutation since permutation talks about arrangement.
The number of ways n objects can be arranged is n! ways
n! = n(n-1)(n-2)!
If a family of 5 is going on a cross-country vacation, and decided to change their seating arrangement. The total seating arrangement that they can have is;
5! = 5*4*3*2*1
5! = 20*6
5! = 120 different arrangements

If an ostrich is 108 inches tall. Then the height of the kiwi will be 22 inches. Then the correct option is A.
What is Algebra?
The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.
The height of an ostrich is 20 inches more than 4 times the height of a kiwi.
Let y be the height of the ostrich and x be the height of a kiwi. Then the equation is given as,
y = 4x + 20
If an ostrich is 108 inches tall. Then the height of the kiwi will be
108 = 4x + 20
4x = 88
x = 22
If an ostrich is 108 inches tall. Then the height of the kiwi will be 22 inches. Then the correct option is A.

k=height of kiwi
h is 20 more than 4 times k
k=20+4k
k=108
108=20+4k
minus 20 from both sides
88=4k
divide both sides by 4
22=k

Answers
Answer:
Label: About 527.9 square centimeters
Aluminum: About 835.7 square centimeters
Step-by-step explanation:
Amount of paper needed for the label:
You can imagine taking off the label and unrolling it, forming a rectangle. The height of this rectangle will be the height of the cylinder, while the length of the rectangle will be the circumference of the cylinder. Therefore, the area of that rectangle will be .
Amount of aluminum needed for the can:
This time, you need to add in the top and bottom of the can as well, which each have area . Together, they have area
. Adding this to the area of the sides, you get a total of about 835.7 square centimeters.
