1/4 is the same as 1 * 0.25
Answer:
see attached diagram
Step-by-step explanation:
First, draw the dashed line 50x+150y=1500 (dashed because the inequality is without notion "or equal to"). You can do it finding x and y intercepts.
When x=0, then 150y=1500, y=10.
When y=0, then 50x=1500, x=30.
Connect points (0,10) and (30,0) to get needed dashed line.
Then determine which region (semiplane) you have to choose. Note that origin's coordinates (0,0) do not satisfy the inequality 50x + 150y>1500, because

This means that origin lies outside the needed region, so you have to choose the semiplane that do not contain origin (see attached diagram).

Drawing a scatter plot for the given values on a graphing calculator, we have;
<h3>How can the function that best represents the data be found?</h3>
The values are;
Day; Running time
1; 8.2
2; 8.1
3; 7.5
4; 7.8
5; 7.4
6; 7.2
7; 7.1
Entering the above values in a graphing calculator, we have;
- The slope of the line of best fit = -0.19
- The x-intercept = 45
Therefore;
- 0 = -0.19 × 45 + y-intercept
0 = -8.36 + y-intercept
The equation found using the statistics function for scatter plot on a calculator is therefore;
