Drag the tiles to the correct boxes to complete the pairs. Match each point of intersection with the system of equations whose solution is at that point.

W X Y Z

y = -2x − 3
y = 2x − 1

y = x + 4
y = -x + 2

y = -2x − 3
y = x + 4

y = 2x − 1
y = -x + 2

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0

answer:

c. the third graph

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.
