Suppose there are 12 equal parts of the house to be cleaned. Max can do 1 per hour, and Maggie can do 3 per hour.

The number of units they can do together in x hours is x+3x. Since there are 12 units to do, x+3x=12. For x=3 this is true, so the sister was right!

The sister is correct, because if you divide 12 by 4 your answer is 3 hours.

A study has shown that the daily amount of milk produced by a dairy cow is
8090 [49]

Answer:

A

Step-by-step explanation:

this is more of a mind game.  Lots of words to throw you off.  Daily a cow produces a mean of 6.2 gallons (average of 6.2 gallons, meaning they already found the mean, "averaged" it out for you) with a deviation of .7 gallons ("give or take" .7 gallons).  On any given day (throw these words out) 68% of the cows (don't need this information to answer the question either, thrown in to confuse you) will produce an amount of milk within which of the following ranges?  Just subtract the deviation ("give or take number") .7 gallons from the mean (average (already determined)) 6.2 gallons which is 5.5 gallons THEN add the deviation ("give or take number") .7 gallons to the mean (average (already determined)) 6.2 gallons which is 6.9 gallons.  Your answer is A 5.5 gallons to 6.9 gallons.     You don't even have to go crazy on the math on this question you can rule them all out but A immediately with subtracting .7 from 6.2.  Mind games .... LOL sneaky.
