The table shows the age of the swimmes on Dions swims team. Find the mean age of the swimmers om the team?
PilotLPTM [1.2K]
Hello!

If we want to find the mean (average) of any set of numbers, all you need to do is add the set together, then divide by how many numbers are in the set.

When we add all the numbers we get: 100

Next we just divide by the number of people which is 10: 100 divided by 10 is 10

So, the mean age of the swimmers on the team is an even number of 10.

X= 7 4. Find the equation of a line passing through (5, -6) perpendicular (b) 3x + 5y = (d) 7x - 12y (f) x = 7 (a) 2x + y = 12 (
goldfiish [28.3K]

Given data:

The first set of equations are x+y=4, and x=6.

The second set of equations are 3x-y=12 and y=-6.

The point of intersection of first set of te equations is,

6+y=4

y=-2

The first point is (6, -2).

The point of intersection of second set of te equations is,

3x-(-6)=12

3x+6=12

3x=6

x=2

The second point is (2, -6).

The equation of the line passing through (6, -2) and (2, -6) is,

\begin{gathered} y-(-2)=\frac{-6-(-2)}{2-6}(x-6) \\ y+2=\frac{-6+2}{-4}(x-6) \\ y+2=x-6 \\ y=x-8 \end{gathered}

Thus, the required equation of the line is y=x-8.
