Which of the following are identities? 1.x^ 2 +2xy+y^ 2 =(x+y)^ 2 11. 2x + 2 = 2(x + 1); 1.0 + a = a

a

step-by-step explanation:

strong negative correlation

step-by-step explanation:

a cube has 6 sides

the probability of getting 5 on the first cube is 1/6 since only one side of the cube has 5 on it.

there are 3 sides of the cube with even number on it [2,4,6]

therefore the probability of getting even number is 3/6

for both events to happen together, the probability would be

1/6 x 3/6 = 12/36

which simplifies to 1/12

a 90 degree rotation across the the origin followed by a reflection across the x-axis.

step-by-step explanation:

the answer is b.6
