Problems 31-33 are very complicated

31.

The top row is the x value, the bottom row are the Y values.

The first point (0,)) would remain the same.

The second point (0,-4) , the -4 moves the the x location and the sign reverses and the X value becomes the y value, so would become (4,0)

The third point the x value becomes the Y value and the Y value becomes the X value, so becomes (0,5)

To get 0,4,0 on the top and 0,0,5 on the bottom.

The answer is B.

32.

Reflecting on the Y, the X values change sign, the Y values stay the same.

First point (-2,0) becomes 2,0

2nd point -5,3 becomes 5,3

3rd point (0,5) becomes 0,5 ( it stays the same since Y = 0)

The answer is D.

33.

Subtract 2 from the X values and subtract 1 from the y values.

5,7 becomes 3,6

3,1 becomes 1,0

2,3 becomes 0,2

The answer is A.

Answer

:we are told that every year the temperature rises by 0.08degrees Centigrade,

So the difference between margin of error and the increase is much higher

That is

0.15-0.08=0.07

But remember Margin of error=Critical value *Standard deviation of population

And it is a quantity that measures accuracy

So the counter argument is that this is still an increase and it should be considered.
