Answer:
I don't understand the "table." I'll assume x increases over a range of values.
Step-by-step explanation:
See attached table.
Answer:
15
Step-by-step explanation:
Let x represent the number of hours it takes the larger hose to fill the pool. Then each hour, it contributes 1/x of the pool volume. Similarly, the other hose contributes a volume of 1/(1.5x) each hour.
The two hoses together contribute a volume of 1/9 of the pool volume each hour:
1/x +1/(1.5x) = 1/9
2.5/(1.5x) = 1/9 . . . . combine the fractions
22.5/1.5 = x . . . . . . multiply by 9x
15 = x
It takes the larger hose 15 hours to fill the pool alone.

Answer: 0.053
Step-by-step explanation:
n(r) = 7
n(b) = 8
n ( g) = 5
Total number of marbles = 20
The probability that both marbles drawn will be green will be
The probability of the first being green = 5/20 and the probability that the second marble is green = 4/19.
We will multiply the two together , we have
5/20 x 4/19 = 20/380 = 0.05263157895
Therefore : the probability, to the nearest 10th of a percent, that both marbles drawn will be green will be 0.053
