Answer:
The equation of line is:
Step-by-step explanation:
We are given that a graph is a that passes through two points:
and
We know that the equation of line passing through two points:
and is given by:
Here we have:
and
Hence, the equation of line is:
Hence the equation of line is:
X=2
y=-2-2x=-2-4=-6
so you choose a
Answer:
D.2.58
Step-by-step explanation:
We have that to find our level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of .
That is z with a pvalue of , so Z = 2.58.
The answer is given by option D.

Answer:
RS = 10
Step-by-step explanation:
We are told that to get ∆QRS, the scale factor of ⅖ was used. To get side RS, we would multiply the side length of the side that corresponds to RS.
YZ corresponds to RS.
YZ = 25
Thus,
RS = 25*⅖
RS = 10
