1 answer:
Answer:
She will go 2.8125 miles in her third run
Step-by-step explanation:
- Karen is training for her upcoming track meet
- She makes 3 practice runs in a 1.5 hour time period
- She runs the distance of each of previous run
- If she ran 5 miles on the first run, how far will she go on her third run
- Assume that she will run x miles in her 1st run
∵ The distance of the 1st run is x
∵ She runs the distance of each of previous run
∴ The distance of her 2nd run is
∴ The distance of her 3rd run is (
)
∴ The distance of her 3rd run is
∵ She ran 5 miles on the 1st run
- Substitute x by 5
∴ The distance of her 2rd run =
∴ The distance of her 2rd run = 3.75 miles
∴ The distance of her 3rd run =
∴ The distance of her 3rd run = 2.8125 miles
* <em>She will go 2.8125 miles in her third run</em>

The residual value, which is the farthest from the line of best fit for the table which shows points and their residual values, is 0.7.
<h3>What is residual value?</h3>The residual value is the estimated value which is calculated for the end of the lease terms for a fixed asset.
Points and their residual values are shown in the table. A 3-column table with 5 rows.
- x 1, 2, 3, 4, 5.
- y 2, 3.5, 5, 6.1, 8.
- Residual Value -0.4, 0.7, -0.2, -0.6 0
The simple regression line can be represented as,
Here α is the constant, β is the slope and <em>e </em>is the residue.
The point which is farthest from the best fit of the line is 3.5. At y=3.5, the value of residue is 0.7.
Thus, the residual value, which is the farthest from the line of best fit for the table which shows points and their residual values, is 0.7.
