The mean of this data is 212.5454 repeating.
To find the mean you need to find the average and to do that you need to add all values and divide by the number of values. When you add all of those numbers, you get 4676. There are 22 values so you would divide 4676 by 22. This answer is 212.5454 repeating.
Well let’s see I tried to think and I couldn’t come up But I’ll tell U when I know
1.)By dividing the given costs per pound (6÷9, or 12÷18) you will get the answer of 1.5. This means it is $1.50 per pound.
2.)If you buy 9 pounds of tomatoes at a $1.50 a pound, you have to multiply to find out how much you get. 9×1.5=13.5
They paid $13.50
3.) To find how many pounds you can buy for $19.50, you have to divide 19.5÷1.5 and you will get 13 pounds.
If it takes the cold water faucet x minutes to fill 1 tub, then its flow rate is (1 tub)/(x min).
The hot water faucet takes 4 times as long, so its flow rate is (1 tub)/(4x min).
Together, the total flow rate is (1 tub)/(3 min), so we have
