Make sure you read the directions for each part carefully. this system of equations will be used in all three? part 1: solve the system by graphing. draw the graphs on paper and indicate their intersection point. type the ordered pair solution here as your answer to part 1. part 2: solve the system using the substitution method. show all work here and indicate the solution for the system as an ordered pair. part 3: solve the system using the addition method. show all work here and indicate the solution for the system as an ordered pair. 4x - 2y = -12 2x +y = -2

If 10 men take 18 days to mow 60 acres of grass, how long will 15 men take to mow 80 acres?

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.
