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?

12= 9x

divide by 9

12/9 =

1.3 =x

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,

the answer is 1 becuz if it were 1.0 that would rip apart the entire so ya. : )
