The probability of picking a green marble the first time is 3/20 and the probability of picking a yellow marble the second time is 8/20.
probabilities are heavily related to percents so it would make sense that the probability of picking a color would be the number of that color divided by the total number.
note that it is really important that the problem said that the marble was replaced. If the marble was not replaced, the probability of picking a yellow marble the second time would be 8/19 if the first marble picked was not a yellow one.
I hope this helps.
Yes. Slope = rise over run so you go up one, over five

Answer:
<u>In week 20, Seth will have 80 cards and Matt will have 60.</u>
Step-by-step explanation:
Let's find out the amount of cards that Math and Seth will have in week 20, using the information shown in the graph and table:
Amount of cards Seth has in week 20 = 20 * 4 = 80
The equation to find out the amount of cards, c, Seth has in week w:
c = 4w
Amount of cards Matt has in week 20 = 20 + (2 * 20) = 20 + 40 = 60
The equation to find out the amount of cards, c, Matt has in week w:
c = 20 + 2w
<u>In week 20, Seth will have 80 cards and Matt will have 60.</u>
Should have subtracted 3x
