A manufacturer estimates that its product can be produced at a total cost of C(x) = 55,000 + 100x + x dollars. If the manufacturer's total revenue from the sale of x units is R(x) = 5200x dollars, determine the level of production x that will maximize the profit. (Round your answer to the nearest whole number.) units Find the maximum profit. (Round your answer to the nearest dollar.)

The first quartile is denoted by Q1. The second quartile separates the lower 50% of the observations from the higher 50% of the observations. The second quartile is denoted by Q2.The second quartile is same as median. The third quartile separates the lowest 75% of the observations from the higher 25% of the observations. The third quartile is denoted by Q3. The third quartile can obtained as follows...." Third Quartile is 1 somehow, and I don't understand how it is.

The mean of the data set {9,5, y, 2, x} is twice the data set {8, x, 4,1,3}. What is (y- x)2?
