The answer to this question is twenty I think
Answer:
x=8
Step-by-step explanation:
The exterior angle of the triangle is equal to the sum of the opposite interior angles
11x+2 = 6x+2 + 40
Combine like terms
11x+2 = 6x+42
Subtract 6x from each side
11x+2-6x = 6x+42-6x
5x+2 = 42
Subtract 2 from each side
5x+2-2 = 42-2
5x = 40
Divide each side by 5
5x/5 = 40/5
x = 8
Answer:
a: sample mean: 130.2 pounds
This is not the population mean
Step-by-step explanation:
To find the mean weight of the sample, add up all the values and divide by the total number of values entered. In this case, 10, so we have...
mean: (136 + 99 + 118 + 129 + 125 + 170 + 130 + 128 + 120 + 147)/10 =
1302/10 = 130.2
This is not the population mean. It is the mean of the sample. We would have to know more information to make a conjecture about the population mean.
