Given the following hypotheses: H0: μ = 480 H1: μ ≠ 480 A random sample of 14 observations is selected from a normal population. The sample mean was 488 and the sample standard deviation 8. Using the 0.10 significance level: State the decision rule. (Negative amount should be indicated by a minus sign. Round your answers to 3 decimal places.)

The square root of 9x plus 7 plus the square rot of 2x equall to 7

Combine the information in the problem and the chart using the average balance method to solve the problem.

Triangle xyz, with vertices x(-2, 0), y(-2, -1), and z(-5, -2), undergoes a transformation to form triangle x? y? z? , with vertices x? (4, -2), y? (4, -3), and z? (1, -4). the type of transformation that triangle xyz undergoes is a . triangle x? y? z? then undergoes a transformation to form triangle x? y? z? , with vertices x? (4, 2), y? (4, 3), and z? (1, 4). the type of transformation that triangle x? y? z? undergoes is a .
