5. Sporting Goods Equipment During the period 1990–2002, the amount of money E in millions of dollars) spent on sporting goods equipment in the U. S. and the
porcent P (in decimal form) of this amount that is spent on exerciso equipment can
be modeled by
E= -5.564 + 149.937 – 1314,6572 + 4396.75€ + 14,439.09
and P = -0.0000214 -0.00051+ 0.002814 + 0.0017+ 0.126
where is the number of years since 1990.
a. Find the values of E and P for i = 0; What does the product E Pmean for
**0 in the context of this problem?
b. Write an equation that models the amount spent on exercise equipment as a
function of the number of years since 1990.
c. How much money was spent in the U. S. on exercise equipment in 1990?

(c) compare the results of parts (a) and (b). in general, how do you think the mode, median, and mean are affected when each data value in a set is multiplied by the same constant? multiplying each data value by the same constant c results in the mode, median, and mean increasing by a factor of c. multiplying each data value by the same constant c results in the mode, median, and mean remaining the same. multiplying each data value by the same constant c results in the mode, median, and mean decreasing by a factor of c. there is no distinct pattern when each data value is multiplied by the same constant. (d) suppose you have information about average heights of a random sample of airline passengers. the mode is 65 inches, the median is 72 inches, and the mean is 65 inches. to convert the data into centimeters, multiply each data value by 2.54. what are the values of the mode, median, and mean in centimeters? (enter your answers to two decimal places.) mode cm median cm mean cm in this problem, we explore the effect on the mean, median, and mode of multiplying each data value by the same number. consider the following data set 7, 7, 8, 11, 15. (a) compute the mode, median, and mean. (enter your answers to one (1) decimal places.) mean value = median = mode = (b) multiply 3 to each of the data values. compute the mode, median, and mean. (enter your answers to one (1) decimal places.) mean value = median = mode = --
