12. Building codes regulate the steepness of stairs. Homes must have steps that are at least 13 inches wide for each 8 inches that they rise.
a. Discuss how to find the slope of the stairs.
b. Describe how changing the width or height affects the steepness of the stairs.

On a certain portion of an experiment, a statistical test result yielded a p-value of 0.21. what can you conclude? 2(0.21) = 0.42 < 0.5; the test is not statistically significant. if the null hypothesis is true, one could expect to get a test statistic at least as extreme as that observed 21% of the time, so the test is not statistically significant. 0.21 > 0.05; the test is statistically significant. if the null hypothesis is true, one could expect to get a test statistic at least as extreme as that observed 79% of the time, so the test is not statistically significant. p = 1 - 0.21 = 0.79 > 0.05; the test is statistically significant.

Suppose that triangle a shown on the grid is translated 3 units to the right and 2 units up to create a triangle a', what is the slope of the hypotenuse of triangle a'?

Part 1: use the graph to count the slope of the line that passes through the points (2,1) and (2,0).part 2 in two or more complete sentences, explain why it is not possible to write the equation of the given line in the traditional version of the point-slope form of a line
