Suppose "true-talent" average exit velocity (AEV) on batted balls for all players is normally distributed with mean 86 mph and a standard deviation of 2 mph. For any sample of individual batted balls hit by one player, the standard deviation of exit velocity around a particular player's true-talent AEV is 8 mph. At this point in the season, Marco Masher has a total of 10 batted balls with an average exit velocity of 94 mph. Given only this information, the best estimate for his true talent exit velocity is closest to which whole number?

M< 5 = 80 , < 2 = 80, < 6= 100, < 3= 100, < 7= 80, < 4= 80, < 8= 100

Ithink it’s a as the answer.

Okay so n is going to represent our first number. since the second number of five times greater than n, the second number will be represented as 5n. for us to figure out the two  numbers we need to have  the value of n first. this is going to be done by adding the two numbers together, n and 5n. it can be simplified as 6n, which the problem states is equal to 72. divide 72 by 6n and you can solve for n.  n+5n=726n=72n=(72/6)n=12  now that we know the value of n, we have to multiply 5 times 12 which equals 60. so our two numbers/integers are 12 and 60
