An advertisement for a popular weight loss clinic suggests that participants in its new diet program lose, on average, more than 10 pounds. a consumer activist decides to test the authenticity of the claim. she follows the progress of 18 women who recently joined the weight reduction program. she calculates the mean weight loss of these participants as 10.8 pounds with a standard deviation of 2.4 pounds. a) set up the competing hypotheses to test the advertisement's claimb) at the 5% significance level, what is the critical value(s)? specify the decision rulec) what does the consumer activist conclude?

x+y=90

x=30-y=x

step-by-step explanation:

if you understand you will get the answer

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2

step-by-step explanation:

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
