Answer:

D. is the answer if you are given that 40% are purple and 18% are green.

Step-by-step explanation:

So if you do this with replacement, it is just P(green)*P(purple).  Here the probability of purple will not be change because we are putting the first bead back in the bag.

P(green)*P(purple)=.18*.4=0.072 or 7.2%

It’s only one question plz help (DON’T GUESS NO LINKS) please I will do anything there is a part two I’m struggling and this is
pshichka [43]

Answer:

For question 1 it's B

For question 2 it's C

Step-by-step explanation:

<u>For question 1, you have to apply the "Triangle Inequality Theorem"</u>

A+B > C

B+C > A

A+C > B

Let's say that A=22, B=17, C= 14

22+17 > 14       True

17+14 > 22       True

22+14 > 17       True

Therefore, the answer is B

<u>For question 2, you apply the rule of the sum of the triangles which is 180°</u>

70+70+? = 180

140+? = 180

? = 40

Therefore, it's C
