Answer:
11.
Step-by-step explanation:
Lower quartile = (12 + 8) /2 = 10
Upper quatrile = (20+22)/2 = 21
Interquartile range = 21-10 = 11,
Answer:
1. It has two points in common with the x-axis.
2. The vertex in relation to the x-axis is at 
Step-by-step explanation:
The points that the equation has in common with the x-axis are the points of intersection of the parabola with the x-axis.
To find them, substitute y=0 and solve for "x":

Use the Quadratic formula:

It has two points in common with the x-axis.
To find the vertex in relation to the x-axis, use the formula:

Substituting values, you get:

The winner got $70,000 and the runner up got $14,000
Let the winner be represented by x and runner up by y
Data given;
- Amount to be shared = $84000
- x = 5y
This is a simple case of ratio i.e 1 : 5
<h3>Equation</h3>

The runner up received $14000. let's use this data to find how much the winner got.

From the calculations above, the winner got $70,000 and the runner up got $14,000.

2 and 1/4 miles is how far Mary walks around the track. This is because she walks for 15 minutes before Jerry gets there, which is 0.75 miles at 3mph. Then Jerry goes for 2 miles, which is half an hour. Half an hour is double 15 minutes, so it's double 0.75 miles. So 0.75 plus 1.5 = 2.25 Mark me brainliest :3
It's increasing cause it's going higher if it's decreasing it's going lower
