Answer:
He could work 10 hours as a lifeguard, and 5 hours as a tutor
Step-by-step explanation:
If he makes $16 an hour as a lifeguard
and $18 an hour as a tutor,
He could work 10 times $16, to make $160 for 10 hours.
Now we subtract this from $250, this makes $90.
We know need to find out how many times 18 goes into 90, 5 times.
So we know that he could work 10 hours as a lifeguard and 5 hours as a tutor.
I hope this is right.
I hope this helps too, have a nice day!
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
