Draw the graph of the equation 3x - 2y = 4. From the graph, find the coordinates of the point whose y -coordinate is 7

(6, 7)

Step-by-step explanation:

If the y coordinate is 7, all you have to do is put 7 into the equation and then it would be 3x-2(7)=4. So, 2 x 7 is 14. Add that 14 to make sure the x is by itself. Add the 14 to the 4 and you get 18. Then divide the 3x by 3 and that becomes x=. Then divide 18 by 3 and you get 6. So the answer (if I understood the question correctly) would be (6, 7)

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
