What mistake was made in solving the following system of equations given? y = 3x – 4

y = 5x + 2

Step 1- 3x – 4 = 5x + 2
Step 2- -4 = 2x + 2
step 3- −2 = 2x
step 4- −1 = x
A-Should have added 3x to both sides in Step 1
B-Should have divided by -2 in Step 3
C-Subtracted incorrectly from Step 2 to Step 3
D-Should not have solved for y

Cameron made 1 loaf of bread. his family ate 4/6 of the loaf of bread. how much of the loaf of bread remains? /

The discrete random variables x and y take integer values with joint probability distribution given by f (x, y) = a(y−x+1) 0 ≤ x ≤ y ≤ 2 or =0 otherwise, where a is a constant. 1 tabulate the distribution and show that a = 0.1.2 find the marginal distributions of x and y. 3 calculate cov(x, y).4 state, giving a reason, whether x and y are independent. 5 calculate e(y|x = 1).
