Histograms are useful when we have data which can be divided into several classes or groups. The histogram shows the trend of each class and the trend among the different classes. For example when we have about 50 different values ranging from 1 to 20, it will be a better approach to draw a histogram in this case by dividing the data into small ranges e.g 1 to 4, 5 to 9 and so on and counting the frequency for each class.

Dot plot is useful when we have a small number of individual values. In this case we can visualize how many times each individual value occurred in the data. This is useful when the number of values in the data is less.

In the given scenario, we have 12 values in total ranging from 1 to 5. So making a dot plot would be the best choice. A histogram would not be useful in this case.

Therefore, the correct answer is option D. Dot plot, because a small number of scores are reported individually

Kendra has $3.15 in dimes and nickels. If she has 4 times as many dimes as nickels, how many of each coin does she have?
svetoff [14.1K]
  • It is important to note that:

A nickel = $0.05

A dime = $0.10

We would be representing,

The number of nickels =  n

The number of dimes = d

  • Kendra has $3.15 in dimes and nickels. Writing this statement as an algebraic expression:

0.05n + 0.10d = 3.15...............Equation 1

  • She has 4 times as many dimes as nickels. The algebraic expression for this statement :

4n = d ........................................ Equation 2

We would substitute 4n for d in Equation 1

0.05n  + 0.10 x 4n = 3.15...............Equation 3

0.05n + 0.4n = 3.15

0.45n = 3.15

Divide both sides by 0.45

0.45n/0.45 = 3.15/0.45

n = 7

The number of nickels is 7

We solve for d, the number of dimes

4n = d

n = 7

4 x 7 = d

28 = d

The number of dimes is  28

Therefore, Kendra has 7 nickels and 28 dimes
