Answer:

If the maximum of function r(x) and t(x) occur at the same point c in domain P = max(r(x)+t(x)) = M+N

In general P  ≤  M+N

Step-by-step explanation:

If the maximum of function r(x) and t(x) occur at the same point c in domain then M=r(c) and N=t(c) So in this case P = max(r(x)+t(x)) = M+N

In general P  ≤  M+N

by definition of maximum  

r(x)≤M,t(x)≤N   for all x in domain

=>  r(x)+t(x)≤M+N   for all x in domain

=> max(r(x)+t(x)) <= M+N

=> P  ≤  M+N

Thus we get in general the relationship is P  ≤  M+N

Find a average daily rainfall for a 30 days month if the total rainfall during that period was 16.8 inches.
max2010maxim [7]

Average = 0.56 inches

Solution:

Given data: Total rainfall = 16.8 inches

Total number of days for a month = 30

To find the average of the rainfall.

Formula for average:

\text {Average}=\frac{\text {Sum of the observations}}{\text {Total number of observations}}

\text {Average}=\frac{16.8}{30}

            = 0.56 inches

Average = 0.56 inches

Hence, average of daily rainfall is 0.56 inches.
