The following dot plot shows the pulse rates of runners after finishing a marathon



Which of the following data sets is represented in the dot plot?


A. {145, 165, 175, 1853}

B. {145, 150, 150, 152, 153, 160, 163, 165, 170, 170, 178, 179, 185}

C. {1, 5, 6, 1}

D. {145, 165, 165, 165, 165, 165, 175, 175, 175, 175, 175, 175, 185}

The following dot plot shows the pulse rates of runners after finishing a marathon Which of the following data sets is represented in the dot

Answer :

The data set that represented by the dot plot given is:

D. {145, 165, 165, 165, 165, 165, 175, 175, 175, 175, 175, 175, 185}

In a dot plot, each data point in a data set is represented by a dot.

To find out the data set that is represented in the dot plot, list out the data points as plotted on the dot plot given.

Thus:

  • 145 - 1 dot = 145
  • 165 - 5 dots = 165, 165, 165, 165, 165
  • 175 - 6 dots = 175, 175, 175, 175, 175, 175
  • 185 - 1 dot = 185

Therefore, the data set that represented by the dot plot given is:

D. {145, 165, 165, 165, 165, 165, 175, 175, 175, 175, 175, 175, 185}

Answer: D. {145, 165, 165, 165, 165, 165, 175, 175, 175, 175, 175, 175, 185}

Step-by-step explanation:

In the given dot plot that is showing the pulse rates of runners after finishing a marathon, it can be seen that ,

There are 1 dot on 145, 5 dots on 165, 6 dots on 175 and 1 dot on 185.

So , the data sets is representing this would be {145, 165, 165, 165, 165, 165, 175, 175, 175, 175, 175, 175, 185}
, which has the same number of values as the dot plot.

Hence, the data set representing the dot plot would be :

D. {145, 165, 165, 165, 165, 165, 175, 175, 175, 175, 175, 175, 185}
