Because they are similar, we could do 180-52-62= 66

The scale factor is 1/2, because each side is dilated 1/2 to get to the new shape. 

HAHA that's funny, I have another one Here’s some advice: At a job 
interview, tell them you’re willing to give 110 percent. Unless the job is a statistician.

160/2187

the slope is -1

a. x intercept is (-3,0)

b. y intercept is (0,2)

For c, just find points that satisfy the equation and connect the points to form the graph. 

Thanks!!!

There are 6 choose 3 ways for 3 of the dice to show even numbers and 3 of them to show odd numbers. Each roll is even with probability 1/2 and odd with probability 1/2, so each arrangement of 3 odd numbers and 3 even number occurs with probability (1/2)^6. Thus, the probability that 3 dice out of 6 show even numbers is 5/16

Is it possible to translate into Enlgish?

You just plug in the 21 for m and 12 for n.

1/3(21) - 1 - 1/2(12) = 7 - 1 - 6 = 0

The answer is zero
