A jar contains nine blue marbles, eight yellow marbles, 11 black marbles, and 12 red marbles.

Without looking, what is the probability of pulling a white marble from the jar?

1
0
3/10
9/40

0%

Step-by-step explanation:

The first thing you need to do, is add the total of all of the marbles together.

9 + 8 + 11 + 12 = 40.

Knowing this, you can take the amount of white marbles, (0) and put this against the 40 total marbles.

Since there are 0 white marbles in the jar, you know that it is impossible to pull one out of the jar.

the 2 figures are congruent bc if you reflect abcd over the y axis then over the d axis the figures overlap

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
