Answer:
two ways
Step-by-step explanation:
there are two ways to do this
640/4 =160
take 160x16 = 2,560
OR
640x4 = 2,560
4 because 4x4 = 16
First,we need to understand the point-slope form:
Where x and y are the coordinates and m is the slope.
Put the above information into the equation:
y-(-6)=-3/4(x-2)
y+6 = -3/4 (x-2)
Therefore the answer is C.y+6 = -3/4 (x-2).

Answer: (13.4996, 32.5004)
Step-by-step explanation:
The confidence interval for mean difference is given by :-
,
where = sample mean difference .
= critical t value (two-tailed)
SE= Standard error.
Given :
SE= 4.2
Now, the confidence interval for mean difference will be :-
Hence, the required confidence interval : (13.4996, 32.5004)
