What’s the system of equations for 2x+3y=5 and 2x+4y=9

x+y=0 and x+y=3

Step-by-step explanation:

not sure what you mean. but answers add comment and ill check it.

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
