B. 75.
Explanation: You're more likely to get 75 as the answer because it's in the middle of the symmetric distribution. The equation for the mean average is
sum of all numbers / how many number there are. And at the middle is where all the averages are.

Answer: $489.13</h3>
===========================================================
Work Shown:
1 yard = 3 feet
1/3 yard = 1 foot .... divide both sides by 3
1 ft = 1/3 yard
11 ft = 11/3 yard ... multiply both sides by 11
13 ft = 13/3 yard ... same idea, but now with 13
-----
area in square yards = (11/3)*(13/3) = 132/9 square yards
Multiply this area with the cost per square yard ($33.35) to get
(132/9)*33.35 = 489.133333
Rounding to the nearest penny, we get $489.13
Add 60+15, divide by 3, subtract 2
Answer: 166 2/3m
Step-by-step explanation:
Area of a rectangle = length times width
Length: 16 2/3
To find the width, multiply it by 3/5.
w = 16 2/3 · 3/5
w = 10
Then, multiply the length by the width.
a = l · w
a = 16 2/3 · 10
a = 166 2/3m
Answer:
9.4 m/s
Step-by-step explanation:
We are given that
Height of pile driver above a pile =h=4.5 m
Acceleration due to gravity=
According to law of conservation of energy
K.E=Potential energy
Substitute the values
m/s
Hence, the velocity of pile driver as it hits the pile=9.4 m/s
