Answer:
The odd in favor of drawing a red marble is 5:8
Step-by-step explanation:
Let’s calculate the probability of selecting a red marble
That would be;
number of red marbles/Total number of marbles
Total number of marbles = 2 + 5 + 6 = 13
So the probability of drawing a red marble is 5/13
The probability of not drawing a red marble = 1-5/13 = 8/13
So the odd in favor of drawing a red marble is 5:8
9514 1404 393
Answer:
62.5 oz of 100%
Step-by-step explanation:
Let p represent the number of ounces of pure syrup. Then (100-p) is the number of ounces of 60% syrup. The amount of maple syrup in the desired mix is ...
p +0.60(100 -p) = 0.85(100)
0.40p +60 = 85 . . . . . . . . . . . simplify
0.40p = 25 . . . . . . . . . . subtract 60
p = 62.5 . . . . . . . . . divide by 0.4
62.5 ounces of pure syrup should be mixed with the diluted syrup to make 100 ounces of 85% maple syrup.
_____
The other 37.5 ounces will be 60% syrup.
