I'm thinking of two numbers. Their difference is 8. And they = 8. when they are subtracted they =8 what are the two numbers?

What is the standard form of -5x^2+2x^4-11+x^3+3x

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?

Mika taught her sister the steps for dividing a decimal by a decimal. which instructions are correct? 1. multiply the divisor by a multiple of 10 to create an integer divisor. 2. multiply the dividend by the same multiple of 10 as step 1. 3. divide, and apply the rules for dividing signed numbers. 1. multiply the dividend by a multiple of 10 to create an integer. 2. multiply the divisor by the same multiple of 10 as step 1. 3. divide, and apply the rules for dividing signed numbers. 1. divide the divisor by a multiple of 10 to create an integer divisor. 2. divide the dividend by the same multiple of 10 as step 1. 3. divide, and apply the rules for dividing signed numbers. 1. divide the dividend by a multiple of 10 to create an integer. 2. divide the divisor by the same multiple of 10 as step 1. 3. divide, and apply the rules for dividing signed numbers.huy
