You would see how many times 6 goes into 30. Which is 5. so you would take 2.5 multiplied by 5. which equals 11 hours
N=12
Since 5/6 and n is being multiplied, you have to divide the 5/6 from both sides. When you divide with a fraction, you have to find it’s reciprocal and multiply with it. So the 5/6 turns into 6/5
5/6 * 6/5 = 30/30 which is one.
10 * 6/5 is 60/5
60/5= 12
Answer
Step 1 the first one is the answer
Answer:
172.5
Step-by-step explanation:
mean of men=sum/no of men
177=sum/30
sum=177*30
= 5310
mean of women=sum/no of women
164=sum/16
sum=164*16
= 2624
mean height= (5310+2624)/30+16
=7934/46
=172.5
