Answer:
b/4
Step-by-step explanation:
After rewriting the quotient as a fraction,
We can look for common factors to reduce it. 8a and 2a both have the common factor 2a, and since 2a = 1 · 2a and 8a = 4 · 2a, we can reduce our fraction down to
Length (L): 3w + 8
width (w): w
Perimeter (P) = 2L + 2w
128 = 2(3w + 8) + 2(w)
128 = 6w + 16 + 2w
128 = 8w + 16
112 = 8w
14 = w
Length (L): 3w + 8 = 3(14) + 8 = 42 + 8 = 50
Answer: width = 14 inches, length = 50 inches
Answer:
I think it is 4.48.
Explain:
6.16/22 is 0.28 Then 0.28 times 16 is 4.48.

Answer:
Standard deviation is 25.4
Step-by-step explanation:
The standard deviation is a metric that determines the variance a set of data has both above and below the mean. A standard deviation of 25.4 means that the values in a given data set are dispersed in a range of 25.4 units both above and below the mean.
The standard error refers to the Standard Error of the Mean (SEM) which measures the precision of the mean in terms of how much a sample mean is likely to differ from the population mean. By using SEM, individuals can estimate how sure they can be that the mean of the sample reflect the true mean of the population. The standard error always is lower than the standard deviation. Since, 25.4 is the higher number, this number would be the standard deviation.
(-X-13)+(X+13)+(X-13)
The positive x and negative x cancel out and equal zero. The positive 13 and negative 13 cancel and equal zero also. Then you are left with (x-13)
