You randomly select two marbles from a mug containing 5 blue marbles 3 red marbles and 2 white marbles. How many times greater is the probability of selecting 2 white marbles when you replace the first marble before selecting the second marble than when you do not replace the first marble before selecting a second marble?

Will give are given that xy is parallel to zw. if xz is a transversal that intercepts xy and zw, angle angle alternate interior angles. since xy is parallel to zw, we know that these angles are we also know that angle xvy and angle zvw are , and thus congruent. we can conclude that △xyv ~ △zwv using the similarity theorem.

The measure of one angle of an octagon is two times smaller that of the other seven angles. what is the measure of each angle?

Multiply and simplify. (x - 4) (x^2 – 5x – 6) i will mark brainliest if your answer is right. show how you got the answer. if your answer is correct but does not show how you got the answer you will not be marked brainliest.
