First arrange numbers
14,15,15,17,19,20,21,23,24
19 is median
15+15/2=15 is first quartile
Answer:
There are 40 problems on the test
Step-by-step explanation:
Let p = the number of problems on the test
The number of problems on the test times the percent correct is the number correct
p * 85% = 34
p * .85 = 34
Divide each side by .85
p * .85/.85 = 34/.85
p = 40
There are 40 problems on the test
Let x is the side of the square
so A = x * x or A = x^2 = 36
As you know 36 is a perfect square root = 6^2
Then x = 6 cm
Perimeter = 4x = 4(6) = 24 cm
Answer:
40 units²
Step-by-step explanation:
Area of Rectangle: A = lw
Step 1: Define variables
<em>l</em> = 8
<em>w</em> = 5
