Answer:
90°
Step-by-step explanation:
From the pie-chart given, the best estimate for central angle for the leading cause which is "Human Error" is: B. 165 degrees.
The leading cause of train derailment will be the cause on the pie-chart that has the largest sector.
From the pie-chart given, the largest sector in the diagram is the sector for "Human Error."
This means that the leading cause is definitely "Human Error."
The central angle of the sector for "Human Error." is between 90 degrees and 180 degrees. That's less than half a full circle and less of a quarter circle. The best estimate from the given options is <u>165 degrees.</u>
Therefore, from the pie-chart given, the best estimate for central angle for the leading cause which is "Human Error" is: B. 165 degrees.

The better value is Quick Clean. Quick Clean is $0.03 cheaper per roll of paper towel.
To get there -
1. divide your price by your amount to get the unit price for one of the item (in this case paper towels)
2. do the same for your other price.
3. make sure you are keeping things labeled and separate so you know what means what :)
4. compare the two prices and decide which one answers the question you are being asked (again in this case which is a better deal)
Hope that helps!
