Running times for 400 meters are normally distributed for young men between 18 and
30 years of age with a mean of 93 seconds and a standard deviation of 36 seconds.
what is the proportion of men having running times faster than 120 seconds? (hint:
remember running faster means the finishing time is a smaller number). round to 3
decimal places.

Given the system of equations presented here: 2x + 4y = 14 4x + y = 20 which of the following actions creates an equivalent system such that, when combined with the other equation, one of the variables is eliminated? multiply the second equation by â’4 to get â’16x â’ 4y = â’80 multiply the second equation by â’1 to get â’4x â’ y = â’20 multiply the first equation by 2 to get 4x + 8y = 28 multiply the first equation by â’1 to get â’2x â’ 4y = â’14
