5. Given the relative-frequency table below, find the expected value of x. x P(X = x) 3 .02 5 .39 7 .12 9 .47

angle uzt is congruent to angle tzy. angle vzw is congruent to angle yzx.

step-by-step explanation:

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)

5x+2x=49

7x=49

x=7. 35 apples

use distributive property on all like terms and change your signs if you have a double negative or if you have positive/negative
