Determine the mean
The mean of a data is calculated as thus:

In this case:

So, the formula becomes:



Answer:
a. 850/85 = 10.625 hr or 10 hr 37 min 30 sec
b. 6:08 AM
C. Average time is (10.625 + 10.8)/2 = 10.7125
or 10 hour 42 min 45 sec
Answer:
61
Step-by-step explanation:
and let c looks to be a right angle
The system of inequalities is x+y≥250 and 3x+2y≤800.
Step-by-step explanation:
Given,
People to invite = at least 250
At least 250 means that the number can increase from 250.
Cups to be provided = only 800
It means the number cannot exceed 800.
Number of adults = A
Number of children = C
According to given statement;
x+y≥250
3x+2y≤800
The system of inequalities is x+y≥250 and 3x+2y≤800.
