Peter won £75 as a prize.He gave 4/5 of the prize money as a present to Roger and Bethan.Roger and Bethan shared the present in
Molodets [167]
Roger: $24
Bethan: $36

Explanation:
4/5 of $75 is $60

So $60 is distributed to Roger and Bethan in the ratio 2 : 3.

Add the numbers in the ratio 2 : 3
2 + 3 = 5

Divide $60 by 5
60 ÷ 5 = 12

Multiply each number in the ratio 2 : 3 by 12:
2 • 12 : 3 • 12
= 24 : 36

I’m sorry if I explained this badly
But if my answer was correct, brainliest please!
Have a nice day!

The table shows the time 50 students spent on their homework.
seraphim [82]

Answer: Mean = 52.8 mins

Step-by-step explanation:

We have lapses of 30 minutes, so we can write the average for each, this means that:

0 < t < 30 can be averaged to the middle of the range: 15 min.

Doing this, we have that:

7 students 15 min

27 students 45 min

12 students 75 min

4 students 105 min.

Now we can calculate the mean:

mean = (x1*n1 + x2*n2 + ...)/N

where x1 is the amount of time 1, and n1 is the number of students associated to that time and so on. N is the total number of students

Mean = (7*15min + 27*45min + 12*75min + 4*105min)/(7 + 27 + 12 + 4)

Mean = 52.8 mins
