Ming made a triangular picture frame out of cardboard. the sides of the frame are 6.75 in., 6.75 in., and 8.375 in. ming uses the addition below to determine the amount of string she needs to decorate the edges of the frame. mc012-1.jpg which explains ming’s error? she should have included the decimal in 6.75 and aligned the decimal points to add 6.750 + 6.750 + 8.375 = 21.875. she forgot to put the decimal point in two of the numbers: 0.675 + 0.675 + 8.375 = 9.725.. she added 6.75 twice, and she should have only added it once: 6.75 + 8.375 = 15.125. she should have placed a zero placeholder after the decimal point to add 6.075 + 6.075 + 8.375 = 20.525.

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.
