The correct answer to
this would be:
“No, because the sample
is not representative of the whole population.”
Since the <span>sample values are the 10 highest annual salaries of TV
personalities, they give almost no information about the salaries of TV
personalities as a whole or in general. </span>
Answer:
I believe it is C) decreasing when x > -1
Step-by-step explanation:
If you plot all 3 points on a graph, you will notice that the parabola is facing downwards. This means that on the left side of the vertex, it is increasing (the y-value increases). On the right side of the vertex, it decreases (y-value decreases). Note that "decreasing" refers to the y values.
So, since the vertex's x-value is -1 (we know this from the point (-1, 2)), any x-value greater than -1 will be to the right of the vertex. For example, 0, 1, 2, 3, etc. are all greater x-values than -1, so they are all to the right of -1. Since they are on the right, that means the corresponding-values will be decreasing.
Therefore, when x > -1, the parabola is decreasing.
Answer:
c = 0
Step-by-step explanation:
A 3-variable linear system of equations is constructed after replacing known values for x and y:
After making algebraic manipulation, the following solution is found:
and 
and 
The value of c is 0.
Answer:
43%
Step-by-step explanation:
Since, 43 square out of 100 are shaded, hence shaded area represents 43%
Since $50 is the fixed rate that would be your y intercept. Since $25 is charged per hour, this value changes and is the slope. Therefore y=25x+50
