Use v = 3 and y = 6 to determine if the expressions 3x + 2(x + 1) - 4 and 16 + 3v – v are equivalent. which
statements are true? check all that apply.
o the value of both expressions when v = 3 is 13.
0 the value of both expressions when u = 3 is 22.
the value of both expressions when u = 6 is 28.
the value of both expressions when v = 6 is 46.
0
o
the expressions are equivalent.
the expressions are not equivalent.

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
