An economist wants to estimate the mean per capita income (in thousands of dollars) for a major city in California. Suppose that the mean income is found to be $24.4 for a random sample of 748 people. Assume the population standard deviation is known to be $10.6. Construct the 85% confidence interval for the mean per capita income in thousands of dollars. Round your answers to one decimal place.

step-by-step explanation:

subtract 7, so the answer is x < = 3, or c.

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,

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval
