Answer:

Mean of the lengths = 10 meters

Step-by-step explanation:

A group for kangaroo friends had a jumping contest and measured their jumps.

Pocket jumped 16 meters. hopster jumped 9 meters and joey jumped 5 meters.

We have to calculate the mean length of their jumps.

Since mean of jumps will be = [tex]\frac{\text{Total lengths of jumps}}{\text{number of kangaroo friends}}[/tex]

Mean = [tex]\frac{(16+9+5)}{3}[/tex]

         = [tex]\frac{30}{3}[/tex]

         = 10 meters

The mean length of the three is 10 meters.

What is Mean(Average)?

The mean is the average of all the observations of a set of numbers. it is found by dividing the sum of all the observations of the set by the number of observations in the set.

[tex]\rm{Mean=\dfrac{Sum\ of\ observations}{Number\ of\ observations}[/tex]

Given to us

  • Pocket jumped 16 meters,
  • Hopster jumped 9 meters,
  • and Joey jumped 5 meters

Mean(Pocket, Hopster, Joey)

We know that the mean is the average, therefore,

Sum of all the observations = 16 + 9 + 5 = 30

Number of observations = 3

[tex]\rm{Mean=\dfrac{Sum\ of\ observations}{Number\ of\ observations}[/tex]

[tex]\rm{Mean=\dfrac{30}{3} = 10[/tex]

Hence, the mean length of the three is 10 meters.
