The life expectancies (in years) for men and women in the U. S. can be given using models in slope-intercept form. Women: L = m t + b Men: L = m t + b where t is the number of years since 1980. Suppose that in 1980, women's life expectancy was 77.2 and was increasing by 0.09 years of life expectancy per year of time. (In other words, each year that passed saw women's life expectancy go up an additional 0.09 years.)

This is the number of parts out of 100, the numerator of a fraction where the denominator is 100. submit

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.
