The answer for " J " would be 228
Answer:
с. A matched pairs t-interval for a mean difference.
Step-by-step explanation:
With the sample, we will have possession of the sample mean and of the sample standard deviation, which means that the t-distribution will be used.
We want to find the mean number of back problems for each sample, and estimate the difference. Since the groups are similar, with only the positions in which they work being different, we have matched pairs. So the correct answer is given by option c.
Hello there!
To start off this problem, let's replace f(x) with x in the equation. This gives us the following.

Subtract 3/4*x from both sides.



Now, multiply both sides by 4 to eliminate the fraction on the left side.

Your answer is B. Hope this helps! :)
4x - 5
Or what kind of an answer are you looking for?
5x - y³ = 135x - y³ = 13
The answer can be obtained by simply putting the ordered pair into the equations. First (2 , -9)
5(2) - (9)³ = 135(5) - (-9)³ = 13
10 + 729 = 675 + 729 = 13
739 = 1404 = 13
This is not true. Therefore this is not a solution
Second (3,-6)
5(3) - (-6)³ = 135(5) - (-6)³ = 13
231 = 891 = 13
This is also not true
Therefore, neither ordered pair is a solution.
