Explanation:

The number of dots above 3 is 5
The number of dots above 5 is 2
The total number of dots on both rollers coasters ridden is 5+2=7.

Question 10.

Use the Length of Leaves frequency table for 11-12.

Several scientists went to a field to collect various leaves. When they got back to the lab, they measured each leaf, in feet. They recorded the data in a frequency table.

Question 11.
How many leaves were less than $$\frac{3}{8}$$ft in length?
(A) 19
(B) 30
(C) 7
(D) 9

Explanation:

The length of leaves is 1/8 and its frequency is 11.
The length of leaves is 1/4 and its frequency is 19.
The question asked was the number of leaves was less than $$\frac{3}{8}$$ft in length. To get the answer to add the length of leaves 1/8 and 1/4 and their frequencies:11+9=30.
Because 1/8 and 1/4 are less than 3/8.

Question 12.
How many more leaves are $$\frac{1}{4}$$ft than $$\frac{3}{8}$$ft and $$\frac{1}{2}$$ft combined?
(A) 19
(B) 30
(C) 7
(D) 9

Explanation:
The leaves of $$\frac{1}{4}$$ft and its frequency=19
The leaves of $$\frac{3}{8}$$ft and $$\frac{1}{2}$$ft combined and its frequencies are: 7+3=10.
We need to find out the number of more leaves present in 1/4 than 3/8 and 1/2=19-10=9.

Question 13.

Explanation:
Add all the frequencies present from 1 and above.
The number of her friends who read 1 or more books during their vacation:
3+4+1+2+3=13.

Use the Weight of Rocks dot plot for 14-15.

Frank wants to record the weights of the different rocks in his collection. He weighs each rock in pounds and records the data in a dot plot.

Question 14.
How many rocks does Frank have that weigh more than a pound but less than 1.7 pounds?
(A) 9
(B) 7
(C) 14
(D) 10

Explanation:
More than a pound means we need to count from 1.4 and less than 1.7 means we need to count up to 1.6.
Total rocks=3+2+4=9 (1.4, 1.5, 1.6).

Question 15.
How many rocks does Frank have in his collection?
(A) 1o
(B) 11
(C) 13
(D) 14

Explanation:
Add all the dot plots from 1.4 to 1.9.
The dot plots are 1.4, 1.5, 1.6, 1.7, 1.8, 1.9 and their dots are 3+2+4+1+2+2=14.

Question 16.

(A) 17
(B) 20
(C) 19
(D) 23

Explanation:
The Kerry spend 4 hours or less=13+10+12=35
The Kerry spend 5 hours or more=5+9+1=15
The number of more times he spends 4 hours or less than 5 hours or more=35=15=20

Question 17.

we need to count the leaves which are having less than 20. This representation will be shown in the diagram.

1| 1 represents 11 goals
1| 4 represents 14 goals
1| 6 represents 16 goals.
These are less than 20 goals.

(A) 2
(B) 4
(C) 3
(D) 6

Explanation:
The dots having on 9/12 are 5
The dots having on 6/12 and 5/12 are 2+1=3
The number of more times he practised for 9/12 than 6/12 and less=5-3=2.

Question 21.
How many times did Chad practice for $$\frac{7}{12}$$ hour?
(A) 2
(B) 3
(C) 4
(D) 5

Question 22.
Brandon borrowed a book from the library. The data show the lengths of time Brandon read the book each day until he finished it. Explain how you would use the data to label and plot the dots on a dot plot. What is the difference between the longest time and shortest time Brandon spent reading the book?

1. The representation must be lowest to highest.
2. Count and write the number of dots above the respective places.
3. The diagram representation is shown below:

The dot plot of 1/4 is having 4 dots.
The dot plot of 1/2 is having 2 dots.
The dot plot of 3/4 is having 1 dot.
The dot plot of 1 is having 1 dot.
In the question asked was the difference between the longest time and shortest time Brandon spent reading the book.
The longest time is 1 hour the dot is 1.
The shortest time is 1/4 hour that’s the dot is 4.
The difference is 4-1=3 hours.
