How much would it cost to buy 10 pounds of peanuts?
Answer: $35
What is the cost per pound?
Answer: $3.50
Step-by-step explanation:
So first, to find the anser to the first question, we need to find out the second question. So, what is the cost per pound.
Well if she got 4 pounds for $14, we should try dividing 14 by 4.
14 divided by 4 = 3.5 ($3.50)
So the cost per pound is $3.50
Now to find out how much it costs if Lulu bought 10 pounds, we need to multiply.
10 x 3.5 = 35
So if she bought 10 pounds, she would play $35
13 out of the 213 tagged returned
13/213 is estimate of how many fraction returned
proportional, marked/totalmarked≈caught/totalinlake
213/13=total/104
times both sides by 104*13 (cross multiply)
213*104=total times 13
22152=total times 13
divide both sides by 13

Answer:
No, none of the number need to be 48 for the mean to be 48. To get a mean, you add up all the number and divide it by the amount of numbers.
Example:
the mean of 10, 79, 42, 88, 19, and 50 is 48, but the actual number 48 was not part of the set.
10 + 79 + 42 + 88 + 19 + 50 = 288
288 ÷ 6 = 48
