Answer: Our required probability would be 0.35.
Step-by-step explanation:
Since we have given that
Number of boxes = 2
Number of purple marbles in Box A = 30
Number of yellow marbles in Box A = 20
Number of purple marbles in Box B = 15
Number of yellow marbles in Box B = 35
So, If Melanie randomly selects one of the boxes and then randomly selects one marble from that box.
Probability that the marble selected will be purple is given by
Hence, our required probability would be 0.35.
Answer:
1615 / 48
Step-by-step explanation:
So the mixed numbers as improper fractions is:
6 1/3 = 19 / 3
4 1/4 = 17 / 4
1 1/4 = 5 / 4
19 / 3 * 17 / 4 * 5 / 4 = 1615 / 48
It's kinda messy so it might be wrong.
Now you have
<u />
<u>(.15)0.5 lb peanuts</u> = <u>0.075 lb peanuts</u>
0.5 lb nuts 0.5 lb nuts
for every pound of 75% mixed nuts you add, you get .75 lb peanuts, how many pounds, x, do you need to add to get the ratio 50 to 100?
<u>0.075 lb peanuts + 0.75x lb peanuts</u><em> = <u /></em><u> 50 </u><u>
</u>0.5 lb nuts + x lb nuts 100
cross multiply
(0.075 + .75x) 100 = (0.5 + x) 50
7.5 + 75x = 25 + 50x
25x = 17.5
x = 0.7 lb of 75% peanuts
