Suppose that prices of recently sold homes in one neighborhood have a mean of $230,000 with a standard deviation of $6150. Using Chebyshev's Theorem, what is the minimum percentage of recently sold homes with prices between $217,700 and $242,300?

Suppose that the price p, in dollars, and the number of sales, x, of a certain item follow the equation 4 p plus 4 x plus 2 pxequals56. suppose also that p and x are both functions of time, measured in days. find the rate at which x is changing when xequals2, pequals6, and startfraction dp over dt endfraction equals1.5.
