The answer for the question is C - 3
Answer:108.93 repeating
Step-by-step explanation:
1634/15
Solution: We are given the population mean 
Now, in order to find which shift's mean is closest to population mean, we will find the mean of each shift.
The mean of shift 1 is:

The mean of shift 2 is:

The mean of shift 3 is:

The mean of shift 4 is:

We clearly see the mean of shift 2 is close to the population mean. Hence the option B) Shift 2 is correct.
We need to find the increasing function with constant slope.
Let us check each option one by one.
A) 6x -5y =10.
Let us solve it for y to get slope-intercept form
6x-5y =10.
-5y =-6x +10.
y =6/5 x-2.
<em>Slope is 6/5 positive, therefore, it's an increasing function.</em>
<em>A linear function always has a constant slope.</em>
<h3>Therefore, correct option is option A.</h3><h3>A. 6x -5y =10</h3>
All other options are incorrect.
