23 floors
Step-by-step explanation:
Subtract 7 from 30:
30 - 7
= 23
So, she traveled 23 floors.
An equal sign.
If there was an equal sign kt would turn into an algebraic equation imstead of an expression.
Happy to help! Marking my answer as the Brainliest would really be aprreciated.
Answer:
For a data set of N elements:
{x₁, x₂, ..., xₙ}
The mean is:
The mean absolute deviation is:
And the population standard deviation is:
In this case, our set has 5 elements, and the set is:
{2, 4, 6, 9, 14}
The mean of this set is:
The mean absolute deviation is:
And the population standard deviation is:
Answer:
Lets start with the given system of linear equations In order to solve for one variable, we must eliminate the other variable. So if we wanted to solve for y, we would have to eliminate x (or vice versa). So lets eliminate x. In order to do that, we need to have both x coefficients that are equal but have opposite signs (for instance 2 and -2 ...
