Answer:
The standard error of the mean = 5.14 mins
Step-by-step explanation:
Number of random sample (n) = 20
Mean(X) = 31.25 mins
Standard deviation (α) = 23.7 mins
Standard error of mean =
standard deviation / √sample size
= 23.7/√20
= 23.7/4.4721
= 5.14 mins
The correct solution: 4x^2 -27x +167 - 996/(x+6)
Step-by-step explanation:
The width would be 90.
900/100=90
Since it give you the over all square yards, you take that number and divide it by what ever the number would be and that gives you the answer.
