Suppose two proposed computer mouse designs were compared by recording wrist extension in degrees for 24 people who each used both mouse types. the difference in wrist extension was computed by subtracting extension for mouse type b from the wrist extension for mouse type a for each student. the mean difference was reported to be 8.89 degrees. assume that it is reasonable to regard this sample of 24 people as representative of the population of computer users. (a) suppose that the standard deviation of the differences was 10 degrees. is there convincing evidence that the mean wrist extension for mouse type a is greater than for mouse type b? use a 0.05 significance level. (use a statistical computer package to calculate the p-value. use μd = μa − μb. round your test statistic to two decimal places, your df down to the nearest whole number, and your p-value to three decimal places.)

x + 107

step-by-step explanation:

let's say that the number he had before the mistake was x. then, he will have 107 dollars more than this, so the answer is x + 107.

answer: the resulting cross section is a rectangle. solution: a plane parallel to the base of a triangular prism will intersect a cross section that is the same shape as its bases. so the cross section is a triangle.

step-by-step explanation:

a, b, c, d are correct.

step-by-step explanation:

we have g(x) = 3 and are required to find which option is a translation of g(x).

now, 'translation' is a transformation which means to shift the function in any direction and the general form of translation is g(x) + k, where k is any real number.

so, according to the options we see that all are correct as they satisfy the general form of translation.

also, it can be seen from the graph below that the function g(x) = 3 is shifted from its position in all the four options.

answer: two angles are called supplementary if they add up to 180°. example: the two angles (140° and 40°) are supplementary because they add up to 180°.
