So let’s say your doing a problem like mine for instance: Shelly buys 3 cabinets worth 40.89$
and a chair for 27.98$
But you do all the work in your head
And you come out with something like 50.089 now in cents you can’t have anything beyond three numbers after the decimal so what would you do in this instance?

If f(x) = 2x + 2 and g(x) = x? , what is (gºf)(2)?

The number of chocolate chips in an 18-ounce bag of chocolate chip cookies is approximately normally distributed with a mean of 1252 chips and standard deviation 129 chips. (a) what is the probability that a randomly selected bag contains between 1100 and 1500 chocolate chips, inclusive? (b) what is the probability that a randomly selected bag contains fewer than 1125 chocolate chips? (c) what proportion of bags contains more than 1225 chocolate chips? (d) what is the percentile rank of a bag that contains 1425 chocolate chips?
