Mean:
Add all the numbers:
13 + 17 + 15 + 18 + 21 + 13 + 20 + = 16.7
16.7 + 3.7 = 20.4
Mean = 20.4
Median:
Order the numbers:
13, 13, 15, 17, 18, 20, 21
The median, or middle number is 17.
17 + 3.7 = 20.7
Median = 20.7
Mode:
The number that repeats the most is 13.
13 + 3.7 = 16.7
Mode = 16.7
Range:
Highest Number = 21
Lowest Number = 13
21 - 13 = 8
Range = 8
The answer choice that matches is choice A.
Hope this helped☺☺
The approximate mass of the spherical weight is 51 pounds
To answer the question, we need to know what the mass of the sphere is
<h3>Mass of the sphere</h3>
The mass of the sphere m = ρV where
- ρ = density of steel = 0.284 lb/in³ and
- V = volume of sphere = 4πr³/3 where
- r = radius of sphere = 3.5 in
So, m = ρV
= ρ4πr³/3
Substituting the values of the variables into the equation, we have
m = ρ4πr³/3
= 0.284 lb/in³ × 4π(3.5 in)³/3
= 0.284 lb/in³ × 4π × 42.875 in³/3
= 48.706π lb/3
= 153.014 lb/3
= 51 lb
The approximate mass of the spherical weight is 51 pounds
