Answer:
217.33 Ib
Step-by-step explanation:
The mean of a set of numbers is the ratio of the total of these numbers to the number of numbers added. As such where there are x numbers and the sum of these numbers is T, the mean is
= T/x
If the mean weight of 3 outfielders on the baseball team is 194 lb, the total weight of the 3 outfielders
= 194 * 3
= 582 Ib
the mean weight of the 6 other players is 229 lb, the total weight of the 6 outfielders
= 229 * 6
= 1374 Ib
Total weight of the 9 players
= 1374 Ib + 582 Ib
= 1956 Ib
Mean of 9 person team
= 1956/9
= 217.33 Ib

Answer: 12</h3>
Explanation:
Multiply 0.66666667 with 18 to get
0.66666667*18 = 12.00000006
The 6 at the very end is due to rounding error. In reality the 6's in 0.66666667 should go on forever. That 7 is from rounding up.
Anyways, the result 12.00000006 should be 12 exactly.
Note how
12/18 = 0.66666667
when using a calculator.
The areas are as follows:
Deck 1: 5 * 5 = 25ft squared
Deck 2: 5 * 7 = 35ft squared
Deck 3: 5 * 9 = 45ft squared.
They increase by 10ft squared each time.
