<h2>Solving for the Mean, Median and Mode of a Data Set</h2><h3>Answer:</h3>

Mean: 8

Median: 7

Mode: 5

<h3>Step-by-step explanation:</h3>

If we increase each element in the data set by 4, our new data set will be...

\{ 7, 9, 5, 9, 5, 5, 6, 7, 19 \}

The mean of a data set is the sum of all of its elements divided by the number of elements.

Solving for the mean:

\frac{7 +9 +5 +9 +5 +5 +6 +7 +19}{9} \\ \frac{72}{9} \\ 8

The median of a data set is just the middle number if and only if the elements of the data set is arranged according to how less to how great each element is.

If we arrange our data set it will be...

\{ 5, 5, 5, 6, 7, 7, 9, 9, 19 \}

We can do see that our middle number is 7 so this our median.

The mode of a data set is the number that repeated the most. We can see in our data set that the number 5 repeated 3 times. 6 and 19 is 1. 7 and 9 is 2. Since 5 is the number that repeated the most, this is our median.

Are there any linear quantities in the chart shown? And if so, what is the slope of said pairs?
VashaNatasha [74]

The chart does not represent a linear quantity

<h3>How to determine if there are linear quantities in the chart shown?</h3>

From the chart, we have the following coordinates

(x, y) = (0.10, 0.14), (0.50, 0.32), (1.00, 0.46), (1.70, 0.59) and (2.00, 0.63)

To determine if the chart is a linear quantity, we simply calculate the slope using the coordinates.

The slope is calculated as:

m = (y2 - y1)/(x2 - x1)

So, we have:

m = (0.32 - 0.14)/(0.50 - 0.10) = 0.45

m = (0.46 - 0.32)/(1.00 - 0.50) = 0.28

In the above computations, the calculated slopes are not equal

Hence, the chart does not represent a linear quantity
