Answer:
The value for the original mean = 32
Step-by-step explanation:
Here, we want to calculate the original value of the mean.
Let the number of samples be n
Mathematically;
mean = Total value/n
Now, we added 8 to each of values; total value added = 8 * n = 8n
Now, for the new mean of 40; we have
(Total value + 8n)/n = 40
Total value + 8n = 40n
Total value = 40n -8n
Total value = 32n
kindly recall from the beginning of the solution;
mean = Total value/n
mean = 32n/n
mean = 32
So the original value of the mean is 32
V=150.8
V=3.14*36*h/3
V=113.04*4/3
V=452.16/3
V=150.72

Answer:
2×9=9+9
Step-by-step explanation:
Answer:
19/12 or 1 7/12 lbs
5/6 + 3/4
Find a common denominator, aka least common multiple
So, 5/6 becomes 20/24 and 3/4 becomes 18/24
20/24 + 18/24 = 38/24 which simplifies to 19/12 or 1 7/12
