Answer:

See explanation

Step-by-step explanation:

Required

The average

The data whose average is to be calculated are not given.

However, the formula to calculate the average is:

\bar x = \frac{\sum x}{n}

Assume the data is:

1287\ 1215\ 1221\ 1229

This means that the number of schools is 4

So:

\bar x = \frac{1287+ 1215+ 1221+ 1229}{4}

\bar x = \frac{4952}{4}

\bar x = 1238

<em>The average of the assumed data is 1238</em>

Answer:

k = 11

Step-by-step explanation:

Given the points are collinear then the slopes between consecutive points are equal.

Using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (5, 1) and (x₂, y₂ ) = (1, - 1)

m = \frac{-1-1}{1-5} = \frac{-2}{-4} = \frac{1}{2}

Repeat with another 2 points and equate to \frac{1}{2}

with (x₁, y₁ ) = (1, - 1) and (x₂, y₂ ) = (k, 4)

m = \frac{4+1}{k-1} , then

\frac{5}{k-1} = \frac{1}{2} ( cross- multiply )

k - 1 = 10 ( add 1 to both sides )

k = 11
