Answer: Option 'a' is correct.
Step-by-step explanation:
Since we have given that
Dimensions of the room is given by
15 ft by 25 ft
Let x be the width around the rug.
So, new length = 15-2x
new breadth = 25-2x
Since Area of the rug = 264 sq. ft
So, it becomes,

Hence, Option 'a' is correct.
Y=7/5× -71/5
plug in the points into the y=mx+b equation and solve from there and of course there are Fractions so you have to make the same denominators but is just an extra step
The only true statement is A:
"The data show a negative linear relationship."

</h3><h3>
Which statement is true?</h3>
On the graph, we can see how the car's vale decreases almost linearly with the age of the car.
Where the response variable would be the one on the y-axis, which is the car's value.
For that linear behavior, we know that there is a correlation coefficient different than zero. So options B, C, and D are false.
Finally, we already saw the linear behavior (decreasing, so the slope is negative). Then we conclude that the only true statement is A.

Answer:
The 95% confidence interval for the true mean length of the shafts is ($3402.08, $4142.75).
Step-by-step explanation:
A (1 - <em>α</em>)% confidence interval for true mean (<em>μ</em>), when the population standard deviation is known is:

If the population standard deviation is not known, then the confidence interval for true mean is:

A 95% confidence interval for true mean is an interval estimate of the population mean. The interval has 0.95 probability of consisting the true value of the population mean.
It is provided that the 95% confidence interval for mean, based on a sample of size 30 is ($3402.08, $4142.75).
This interval implies that the true mean value is between $3402.08 and $4142.75 with 95% confidence.
Thus, the 95% confidence interval for the true mean length of the shafts is ($3402.08, $4142.75).
