B.w/5
C.5 + w
D.5 + 5w

Answers

Answer 1
Answer: the answer would be option A 
because if you know that David recycles 5 cans a week every week that the week would turn into w and 5 would stay the same so when you put 5 and w (week) together you would get 5w 
(i am not sure if that is right thought i am taking a test with the same question)

p.s. sorry if i confused you i don't really know how to explain it
Answer 2

A bag has 4 red marbles, 12 blue marbles and 6 yellow marbles. What is the probability of picking a yellow marble, replacing it, and then picking a blue marble?a) 1/18
b) 18/121
c) 15/22
d) 22/131

Answers

Probability of picking a yellow marble = no of yellow marbles/total number of mables = 6/(4 + 12 + 6) = 6/22 = 3/11
Probability of picking a blue marble = 12/22 = 6/11

Probability of picking a yellow marble and a blue marble = 3/11 x 6/11 = 18/121

You've decided you want a plant for your room. At the gardening store, there are 4 different kinds of plants (tulip, fern, cactus, and ficus) and 4 different kinds of pots to hold the plants (clay pot, plastic pot, metal pot, and wood pot). If you randomly pick the plant and the pot, what is the probability that you won't get a clay pot or a cactus?

Answers

There are 4×4 = 16 different combinations of plant and pot. Of those, 7 are either clay pot or cactus. Thus the probability you won't get a clay pot or a cactuis is 9/16.

Answer:

9/16
