Answer:
10626 ways
Step-by-step explanation:
Given
Number of students = 23
Prizes = 3
Required
Number of different outcomes for the top 3
This question will be solved using permutation formula because it implies selection of 3 students from 23
<em>Where n = 23 and r = 3</em>
The formula becomes
<em>Hence, there are 10626 ways</em>
If you divide the area of the rectangle by the length (44÷5.5) the answer is 8. Your answer is 8 ft.
Answer:
Geometric mean is the nth root of the product of n numbers
For two numbers it's the square root
for three numbers it's the cube root
for 4 numbers it's the fourth root
etc.
--------------------------
5 and 20
m = √(5 * 20) =
m = √100
m = 10
3 and 12
m = √(3 * 12)
m = √36
m = 6
do the rest the same way
If the length is 7cm, you multiply it by 2 because it’s “twice it’s length”.
7x2 = 14
the width is 14cm.
area of a rectangle = LxW
14x7 = 98
The area of the rectangle is 98cm2
The answer is B
