Answer:
C. 2x-y>-7
Step-by-step explanation:
The Line is not part of the region since is drawn in the graph using a dotted line, but we still need to find its equation.
The equation of a line is y=mx+b, where 'm' is the slope.
'm' can be obtained using the following formula.
To find the slope, as well 'b' we need points from the line, those will be (-6,-5), (0,7) as (x2,y2) and (x1,y1) respectively
Evaluating those point in the formula we have 'm' =2
Using now the above result and the point (0,7) in the equation y=mx+b, we obtain the value for 'b'.
7=2*0+b7
b=7
Hence our line is y=2x+7, and if we write it in standard form we obtain the following> y-2x=7.
Now, since our line is not part of the region, and the region is below that line, there is the < sign.
Hence the inequality that corresponds to the figure is y-2x<7 or, if we multiply by -1 (changin orientation of signs) 2x-y>-7

Answer:
a) "=T.INV(1-0.02,7)"
And we got
b) "=T.INV(0.85,7)"
And we got
Step-by-step explanation:
For this case we have a sample size of n=8, so we can find the degrees of freedom like this:
Part a
For this case we need a value who accumulates 0.02 of the area in the right of the t distribution with 7 degrees of freedom so we can use the following excel code:
"=T.INV(1-0.02,7)"
And we got
Part b
For this case we need a value who accumulates 0.85 of the area in the left of the t distribution with 7 degrees of freedom so we can use the following excel code:
"=T.INV(0.85,7)"
And we got
