For number 9 put the equation in the graphing calculator and see what the outcome is
Answer:
201.24
Step-by-step explanation:
75%x115=86.25
86.25+ 115=201.25
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;

A straight line = 180 degrees.
Subtract the 2 known angles from 180:
180 - 112 - 38 = 30 degrees
Let w=width
w+12
