Answer:
The mean of Martin's scores is 85.2
Step-by-step explanation:
In order to find the mean of a set of numbers, you will have to add up all of the numbers and divide the result by the total numbers in the set.
98 + 78 + 84 + 75 + 91 = 426
Since there are 5 numbers in total, we will do 426 divided by 5.
426 ÷ 5 = 85.2
So, the mean of Martin's scores is 85.2
Answer:
7.05 in^3
Step-by-step explanation:
V = 4/3(pi)r^3 , r = 3/2 = 1.5
V = (4/3)(3.14)(1.5^3)
= 14.10
Now divide by 2 for 1/2 of the ball.
V/2 = 14.10 = 7.05
= 7.05 in^3

Answer:
The height of the parallelogram is 3 yards.
Step-by-step explanation:
A parallelogram has a base of 7 yards, and an area of 21 square yards.
The formula for the area of a parallelogram is A = bh.
So, to find h (the height), that formula becomes h = A/b
h = 21/7
h = 3
The height of the parallelogram is 3 yards.
(Work Check:
A = bh
A = 7 * 3
A = 21)
