190 runners would not have finished the race.
If you add up all the waves, there were 952 total runners.
If 7/8 finished the race, then that means that 1/8 did not finish the race.
Just multiply 1/8 by 952 to get the amount that did not finish.
It would be 190.

Answer:
x = -1 and y = 6
Step-by-step explanation:
using x = -b/2a
x = -4 / 2(2)
x = -1
y = 2(-1)² + 4(-1) + 8
y = 2 - 4 + 8
y = 10 - 4
y = 6
Answer:
A
Step-by-step explanation:
because there variables represent 1 so 1 cant be bigger than one and the other two have real equations
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
