Answer:
m = -2
Step-by-step explanation:
For this problem, we will simply solve the equation for m.
19 - 5 ( 2m - 3 ) + 9m = 36
19 - 10m + 15 + 9m = 36
34 - m = 36
-m = 2
m = -2
Hence, for this equation to be true, m must equal negative 2.

Answer:
B) Paired Z-test for means
Step-by-step explanation:
We are told that the distances travelled are normally distributed.
We are also trying to find out if the average distance travelled by the Titleist Pro V1 golf balls is farther than that of the Callaway Chrome Soft golf balls.
Also, the standard deviation of both cases are known.
Thus, this is where Paired Z-test for means is used.
Presently ratio is at 10:18 = 1.25
With 5 more girls & guys joining, ratio would change to 15:13 = 1.153846154
Therefore, the ratio of girls to boys would change rather not remain the same.
