Answer:

e=20

Step-by-step explanation:

Given there is a scatter plot.

A point on it is (10,7)

The regression line y' = -x-3

We have regression line giving estimate for given value of x

When x=10, actual value of y

= y observed = 7 (given)

As per regression line estimate

y = -10-x = -13

Difference between y estimate and actual y = 7-(-13)

=20

CAN ANYONE HELP ME WITH THIS

Alchen [17]

The line in the middle has a right angle, so the angle just above the Y would be 90 degrees.

The angle to the right of y is given as 48.

The three inside angles of a triangle need to equal 180.

So y = 180 - 90 - 48 = 42 degrees.

==================================================

Explanation:

When applying any kind of reflections, the parallel sides will stay parallel. Check out the diagram below for an example of this.

So PQ stays parallel to RS. Also, QR stays parallel to PS.

The statement "PQ is parallel to PS" is incorrect because the two segments intersect at point P. This letter "P" is found in "PQ" and "PS" to show the common point of intersection. Parallel lines never intersect.
