A rectangle's width is 5 feet less than its length. Write a quadratic function that expresses the rectangle's area in terms of its length.
O A. Al) = lu
OB. 4(1) = w(w+5)
C. A(1) = 12 - 51
O D. 4(1) = 12 + 51

A. find the power of the test, when the null hypothesis assumes a population mean of mu = 450, with a population standard deviation of 156, the sample size is 5 and the true mean is 638.47 with confidence intervals of 95 b. find the power of the test, when the null hypothesis assumes a population mean of mu = 644, with a population standard deviation of 174, the sample size is 3 and the true mean is 744.04 with confidence intervals of 95% c. find the power of the test, when the null hypothesis assumes a population mean of mu = 510, with a population standard deviation of 126, the sample size is 10 and the true mean is 529.44 with confidence intervals of 95
