Area=600
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
1700 and 2550
You might want to double check that. I'm not certain.
Answer: B
Explanation:
Use Pythagorean’s theorem to find it out:
A^2 + B^2 = C^2
8^2 + 15^2 = 17^2
64 + 225 = 289
289 = 289
So these side lengths create a right triangle
