Gross sales receipts (in thousands of dollars) are recorded daily for a sample of 20 small businesses in the New York metropolitan area for a one-day period in March. The mean of the sample is 283.2 and the standard deviation of the sample is 118. The sample results are as follows. 521.0 299.6 430.0 325.0 170.5 248.6 125.5 91.2 353.3 268.6 359.7 207.7 392.1 336.3 467.0 300.3 150.6 139.1 263.6 214.3 a company is considered to be "successful" if its daily sales exceed $200,000. Based on the above sample, what is the point estimate of the true percentage(same as True Population) of companies that are successful?

step-by-step explanation:

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).
