Answer:
18
Step-by-step explanation:
to find the MAD you add all of the numbers first 22+19+30+13+17+21+8+15+12+23= 180
then you divide it by how many numbers there are for instance there are 10 because there are 10 pairs of numbers then you divide it by 180 and you get 18
hope it helped :)
V = (pi) * r^2 * h
V = 470.48
h = 6.5
pi = 3.14
470.48 = 3.14 * r^2 * 6.5
470.48 = 20.41r^2
470.48 / 20.41 = r^2
23.05 = r^2
sqrt 23.05 = r
4.8 = r <=====
Answer:
z = 28
Step-by-step explanation:
Let's try this first:
6 = something - 1
Something = 7
Next:
We know that "something" is 1/4z
1/4z = 7
Divide both sides by 1/4 to isolate z
z = 28
Hope this helps :)
Have an awesome day!!
