The value of point a on the x axis is anywhere that’s from left to right from the origin (0,0) There should normally be indications on where the graph is.
Mean is average example
mean of x,y,z is (x+y+z)/3
so 6 values
mean of 28
that means that they add up to 168
median means the middle number when you arrange them
range means the distance from smallest number to largest number
an example
18,27,29,29,29,36
Answer:
Step-by-step explanation:
What's the question?
The answer would be 17.
This is because, the format for finding out the hypotenuse of a triangle is--
a^2 + b^2 = c^2
So, it would translate to--
15^2 + 8^2 = c^2
225 + 64 = 289
Because 289 = c^2, you need to take the square root of it.
The square root of 289 is 17.
Therefore, your answer is 17.
