Ryan is correct, the mean is about 8.1.
To find the mean, you have to add up all the values, then divide by the total amount.
For Sample A:
60 x 6 + 90 x 7 + 145 x 8 + 150 x 9 + 55 x 10 = 4050
If you add up all the adults, you have 500.
Dividing 4050 by 500 = 8.1
Sample B will produce a very similar result.
Answer:
1.1 qt/s
Step-by-step explanation:
To find quarts per second, divide quarts by seconds:
(63 qt)/(56 s) = 9/8 qt/s ≈ 1.1 qt/s
Since line c and d are parallel, line a can act as a transversal. Thus, x=124 degrees because of the alternate exterior angle relationship that can be seen.
Answer: x= −6
/5 is the answer
