Answer:
Below.
Step-by-step explanation:
10, 14, 13, 13, 16, 12, 9,7
Arrange in ascending order:
7 9 10 12 13 13 14 16
The median = the mean of the middle 2 values
= (12 + 13) / 2 = 12.5 hours.
The mean = (7 +9 +10 +12+ 13+ 13+ 14+ 16) / 8
= 94/8
= 11.8 hours to nearest tenth.
Charge of Ralph:
Charge = $24 + $33 per hour
Let the time worked be = x.
For x hours, the cost = 33*x = 33x
Charge = 24 + 33x
24 + 33x = 189
33x = 189 - 24
33x = 165
x = 165/33
x = 5
The job took 5 hours.

Answer:
Volume is 718 cm^3
Step-by-step explanation:
We need to get the radius of cylinder A
From the base area,
we have that;
A = pi * r^2
18 = 3.142 * r^2
r^2 = 18/3.142
r^2 = 5.73
r= √5.73
r = 2.39
If two shapes are similar, we have the ratio of their corresponding sides equal;
Thus;
2.39/5 = x/10
x = (10 * 2.39)/5
x = 4.78 cm
To get the volume, we use the formula
V = pi * r^2 * h
V = 3.142 * 4.78^2 * 10
V = 717.8 cm^3
This is approximately 718 cm^3
