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;

Answer:
74
Step-by-step explanation:
Say that arc JL going through M is arc E and JL going the other way is arc D
For the angle formed by two tangents, K=(1/2)(E-D)
64=E-D
Furthermore, angle K and central angle JCL (facing toward K) are supplementary, so 180-K=JCL=180-32=148
Thus, as the angles around angle C add up to 360, angle JCL (facing toward M) is 360-148=32+180=212
E is then 212
64=212-D
212-64=D=148
Thus, as JML is an inscribed angle, M=1/2(D)=1/2(148)=74
Perimeter= 2l+2w
126= 2l+2w
l=2w
Substitute the value for l
126= 2(2w)+2w
126= 4w+2w
126=6w
21=w
Plug the value for w in to find l
l=2(21)
l=42
Final answer: Length-42 ft, Width-21 ft
-2x^6 That is pertty short :)
