Amixture of pulverized fuel ash and portland cement to be used for grouting should have a compressive strength of more than 1300 kn/m2. the mixture will not be used unless experimental evidence indicates conclusively that the strength specification has been met. suppose compressive strength for specimens of this mixture is normally distributed with σ = 64. let μ denote the true average compressive strength. let x denote the sample average compressive strength for n = 11 randomly selected specimens. consider the test procedure with test statistic x and rejection region x is 1331.26. what is the probability distribution of the test statistic when h0 is true?

The graph below could be the graph of which exponential function?

Find the given elements if matrix d:

You have learned about the six trigonometric functions, their definitions, how to use them, and how to represent them graphically. the sine, cosine, and tangent trigonometric functions can be paired with their reciprocal functions, cosecant, secant, and cotangent, respectively. think about how each function is related to its reciprocal function.how are the graphs of the reciprocal functions related to their corresponding original functions? what happens to the graphs of the reciprocal functions as x approaches the zeros of the original functions? describe how you would teach friends with different learning styles (visual-spatial, aural-auditory, verbal-linguistic, physical-bodily-kinesthetic, logical-mathematical, social-interpersonal, and solitary-intrapersonal) how to graph the reciprocal functions
