Answer:
we need a picture of the graph
The total snowfall throughout the day is the expected value of the distribution.
The estimated total snowfall during the day is 30 inches
Start by calculating the average rate of snow collected on that day.

This gives

Divide 7.5 by 6

There are 24 hours in a day.
So, the total snowfall is:

This gives

Multiply

Hence, the estimated total snowfall during the day is 30 inches

Answer: its square.
Step-by-step explanation:
Given:
Week 1 : - 40
Week 2 : - 56
Week 3 : 105
Week 4 : 70
Week 5 : 140
Week 6 : ?
At the end of the 6th week, net profit is 252.
Profit = 105 + 70 + 140 = 315
Loss = 40 + 56 = 96
Net Profit = 315 - 96 = 219
252 - 219 = 33 Profit on Week 6.
Average profit : 252 / 6 = 42 per week
You can find the rate of change by taking it's derivative.
