Answer:
m=(150,200,250)
Step-by-step explanation:
this is because the least he can make is 150 which requires 6hrs he can also make 200 and 250 within 10hrs which is well within his limits and needs
Evidently the quesiton is incomplete.
It is logic that the actions are roll a die and draw a card.
The two events are indepent, so the combined probability is the sum of the individual probabiliites.
Probability = number of positive events / number of possible events
Probability of rolling an even number = number of faces with even numbers / total number of numbers.
Probability of rolling an even number = 3 / 6 = 1/2
Probability of drawing an ace = number of aces in the deck of cards / number of cards
Probability of drawing an ace = 4 / 52 = 1 / 13
Combined probability = 1/2 + 1/13 = (13 + 2) / 26 = 15 / 26
Answer: option D. 15 / 26
The rate of Sue is 1 car per hour: 1 (c/h)
then the rate of Steve is 2 (c/h) , because Steve works faster, he can wash twice the number of cars, for the same amount of time.
Thus If Steve and Sue work together, they can wash 1 + 2 = 3
(cars per hour).
That is, the rate of Steve and Sue working together, is 3 (c/h).
In the first 30 minutes, Sue washes half of the car.
The remaining half will be washed at a rate of 3 (c/h)
The main formula is Work = Time * Rate
where Work is washing (1/2)c, and rate is 3(c/h)
Time=Work/Rate =
![\frac{ \frac{1}{2} c}{3 \frac{c}{h} }= \frac{1}{6}h](https://tex.z-dn.net/?f=%20%5Cfrac%7B%20%5Cfrac%7B1%7D%7B2%7D%20c%7D%7B3%20%5Cfrac%7Bc%7D%7Bh%7D%20%7D%3D%20%5Cfrac%7B1%7D%7B6%7Dh%20)
1/ 6 h =(1/6)*60 min = 10 min
Answer: 10 min
