a cylinder has a radius and a height. How many times greater is the surface area when both demensions are multiplied by a factor of 2, 3, 5, 10

2. True

4. True

Step-by-step explanation:

1. The number line of a dot plot would start at 1.

False. The objective of the point diagram is to show the number of times a given event is repeated, therefore the diagram should show the number of times that no mail arrived during the day

2. A dot plot would show 7 points for numbers greater than 2.

 It is true. Note that the data shows this series of numbers greater than 2.

Number Frequency

3 2

4 3

5 1

6 1

Total 7

3. The intervals on a histogram should be 0 to 2, 3 to 4, and 5 to 6.

The intervals should not necessarily have a difference of 2 units.

4. A histogram would have a maximum of 7 bars.

It's true, because there are only 7 different data types {0, 1, 2, 3, 4, 5, 6}

5. A histogram should not show a bar that includes 0 pieces of mail.

It is not true. This histogram should show a bar with 0 pieces because it must show the number of days that no mail arrived. Also in this problem 0 is defined as a class with frequency of 3
