A bag contains 2 snickers bars, 8 twix bars, and 5 crunch bars. A candy bar is chosen, the replaced, then another is chosen. What is the probability of choosing a twix bar and then a crunch bar? (Please answer with a fraction and not a percentage)

2 + 8 + 5 = 15 total candy bars.

8 twix, so picking a twix would be 8/15

5 crunch bars, picking a crunch would be 5/15, which reduces to 1/3

Probability of both: 8/15 x 1/3 = 8/45

c. prove the lengths are the same.

step-by-step explanation:

you need to prove the segments are congruent. congruent segments have the same length. find the lengths of the segments using the distance formula, and compare them.

answer: c. prove the lengths are the same.

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.
