Okay so first since there are 4 red marbles, 4 blue marbles, and 12 yellow marbles, you add them together so the whole total would be 20 marbles now. Since there are 4 marbles, the probability of her pulling it out would be 4/20. So now that she took 1 red marble away, we have 19 marbles left. So now that has been finished, she 1 more yellow marble away so now we have 12/19. Now that it's completed you multiply the two, and now you should have 12/95, divide 12/95 and you'll get 0.126315789 in other words rounded that too the nearest hundredth and you'll get 0.13
Answer:
-13
Step-by-step explanation:
Replacing x with -3 results in f(-3) = -(-3)^2 - 4, or
f(-3) = -9 - 4 = -13
If I did my math right the answer would be X = -5/4
hope this helps!
