Patrick is a health researcher. He wonders if emergency room visits are evenly distributed across the days of the week. He plans to take a random sample of recent visits in order to carry out a χ 2 χ 2 \chi, squared goodness-of-fit test on the results. What is the smallest sample size Patrick can take to pass the large counts condition?

the domain of a function is the set of input values, x , for which a function is defined. the domain is shown in the left oval in the picture below. the function provides an output value, f(x) , for each member of the domain.

yx = 36

step-by-step explanation:

cos f = opposite side/ hypotenuse

cos f = yw / yx

we know cos f = 4/9 and yw =16

4/9 = 16/yx

multiply each side by yx

4/9 yx = 16/ yx * yx

4/9 yx = 16

multiply each side by 9/4

9/4 * 4/9 yx = 16 *9/4

yx = 36
