Abox contains 10 tags, numbered 1 through 10, with a different number on each tag. a second box contains
8 tags, numbered 20 through 27, with a different number on each tag. one tag is drawn at random from each
box. what is the expected value of the sum of the numbers on the two selected tags?

(a) 13.5
(b) 14.5
(c) 15.0
(d) 27.0
(e) 29.0

(E) 29.0

Step-by-step explanation:

If a tag is drawn at random from each box, the expected value of the sum of the tags is the sum of the expected values for each tag.

The expected value for each tag is the mean value of the numbers in its box.

The expected value of the sum of the numbers on the two selected tags is 29.

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)
