6 ft for each side, bc area is side times side, which 6x6=36
I think that first one represents a function.
The answer is 2/3 for a fraction and the decimal number is 0.6666666667
Step-by-step explanation:
Confidence interval = mean ± margin of error
CI = μ ± ME
The mean is μ = 8.7.
Margin of error = critical value × standard error
ME = CV × SE
At 95% confidence and 9 degrees of freedom, CV = 2.262.
SE = s / √n
SE = 3.3 / √10
SE = 1.04
The margin of error is:
ME = 2.262 × 1.04
ME = 2.36
CI = 8.7 ± 2.36
CI = (6.34, 11.06)
It’s going up by 2/9 . if you did it for the first one it’d b 3/9 which is 1/3
