At 9:00, Paula has x cups of food in a container for her dog. Paula pours a 2 1/2 cup box of food into the container. Then she removes 3/4 cup of food to feed her dog. Now there are 5 1/4 cups of food in the container. write an equation that can be used to determine the number of cups, x, of food in the container at 9:00?

Which equation can be used to determine the number of cups of food, x, in the container at 9:00?

A.5 1/4 = x + 212 + 34
B.5 1/4 = x − 212 + 34
C.5 1/4 = x + 212 − 34
D.5 1/4 = x − 212 −34

(co 3) the times that customers spend in a book store are normally distributed with a mean of 39.5 minutes and a standard deviation of 9.4 minutes. a random sample of 25 customers has a mean of 36.1 minutes or less. would this outcome be considered unusual, so that the store should reconsider its displays? no, the probability of this outcome at 0.035, would be considered usual, so there is no problem yes, the probability of this outcome at 0.035, would be considered unusual, so the display should be redone no the probability of this outcome at 0.359 would be considered usual, so there is no problem yes, the probability of this outcome at 0.965 would be considered unusual, so the display should be redone
