The selling price for houses in a neighborhood in West Richland, WA have an approximately normal distribution with a mean selling price of $275,000 and a standard deviation of $10,500.
If 35 homes sell in this neighborhood, what is the probability that the average selling price of the 35 homes will
be within $2000 of the true mean (that is, what is the probability the sample mean will be between $273,000
and $277,000)?
Include four decimal places in your answer.

Write a polynomial that fits the description: a third-degree polynomial with leading coefficient -4

Use composition to determine if (x) or h(x) is the inverse of f(x) for the limited domain x2-1.

Ican interpret and represent the remainder in division calculations sensibly for the context (eg if we wont to know how many 40 seat buses will be needed to transport 170 students for on excursion, we divide 170 by 40 and realise buses and another smaller vehicle to that we need 4 transport 10 more students) solve the following questions. show your work! 11) the zoo had 420 butterflies that needed to be transported to a new enclosure. the boxes that the butterflies would be moved in only hold 80 butterflies in each. how many boxes would they need? 2 12) each classroom in the school can have exactly 25 students, if there are 345 students in the school how many full classrooms are there?
