You are buying potato chips at the grocery store. you have a manufacturers coupon for a $1.00 off and the store is offering 20% off if you buy 2 bags. you decide to buy 2 bags of potato chips. how do you compute your final cost?

a. subtract $1.00 off each bag and then multiply by .20
b. multiply each bag by .20, subtract $1.00 off of each bag, and then add them together.
c. add the two bags together, multiply by .80, and then subtract $1.00.
d. subtract $1.00 from the first bag, then add them together, and then multiply by .80.

You are responsible for designing a new city. you are inspired by pierre charles l'enfant, who laid out the streets of our nation's capital. numbered streets run north and south, and lettered streets run east and west. avenues are named after states, and they intersect the streets on a diagonal. the streets are parallel and the intersections form similar triangles. 18th st. is 454 meters long and the intersection of 18th and k st. is 207 meters from connecticut ave. if 19th st. and k st. is 385 meters from connecticut ave., what is the length of 19th st.?

The table shows population statistics for the ages of best actor and best supporting actor winners at an awards ceremony. the distributions of the ages are approximately bell-shaped. compare the z-scores for the actors in the following situation. best actor best supporting actor muequals42.0 muequals49.0 sigmaequals7.3 sigmaequals15 in a particular year, the best actor was 59 years old and the best supporting actor was 45 years old. determine the z-scores for each. best actor: z equals best supporting actor: z equals (round to two decimal places as needed.) interpret the z-scores. the best actor was (more than 2 standard deviations above more than 1 standard deviation above less than 1 standard deviation above less than 2 standard deviations below) the mean, which (is not, is) unusual. the best supporting actor was (less than 1 standard deviation below more than 1 standard deviation above more than 2 standard deviations below more than 1 standard deviation below) the mean, which (is is not) unusual.

How can you find the mean absolute deviation (mad) for this set of data?
