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

Solve this equation, <br> -13m=-377

lozanna [386]

-13m = -377
m= -377/-13
m=29
the negatives cancel out. so just do 377/13 which equals 29
