Answer:
no solutions
Step-by-step explanation:
distribute the 4 to get:
-12b - 56 = -12b
add 12b to each side to get:
-56 = 0
since -56 does not equal 0 there are no solutions
Answer:
-2x - 12 - 2
Step-by-step explanation:
- Apply the distributed property: -2x - 12 - 2
I hope this helps!
This is the answer for both number 9 and number 11.
Good luck
Answer:
Option D
Step-by-step explanation:
A reporter collects a random sample of 50 runners from all the runners who finished the Cherry Blossom Ten Mile Run in 2009 and constructs a 99% confidence interval for the true mean finish time to be (86.05, 99.38) minutes.
Assuming the reporter performed the calculations correctly, which of the following statements are appropriate interpretations of this confidence interval?
We can expect that 99% of confidence intervals created using the same method the reporter used will contain the true mean run time for runners of this race.
The table is missing in the question. The table is attached below.
Solution :
Let X = appraised value
Y = area (square feet)
The regression line is given by :







The regression line is :

To estimate the error variance, we have:
Error variance,
