A company that makes thing-a-ma-bobs has a start up cost of $44055. It costs the company$1.97 to make each thing-a-ma-bob. The company charges $5.31 for each thing-a-ma-bob. Let x denote the number of thing-a-ma-bobs produced. Write the cost function for this company. C(x) = Write the revenue function for this company. R(x) = What is the minumum number of thing-a-ma-bobs that the company must produce and sell to make a profit?

Analyzing functions ANSWERED asked 2020-12-29 Regarding analysis of residuals, decide in each case which assumption for regression inferences may be violated. a. A residual plot-that is, a plot of the residuals against the observed values of the predictor variable-shows curvature. b. A residual plot becomes wider with increasing values of the predictor variable. c. A normal probability plot of the residuals shows extreme curvature. d. A normal probability plot of the residuals shows outliers but is otherwise roughly linear.

Analyzing functions

Let S be an ordered set and A is a nonempty subset such that sup A exists. Suppose there is a $$\displaystyle{B}⊂{A}$$ such that whenever $$\displaystyle{x}∈{A}$$ there is a $$\displaystyle{y}∈{B}$$ such that $$\displaystyle{x}≤{y}$$. Show that $$\displaystyle\supset{B}$$ exists and $$\displaystyle\supset{B}=\supset{A}$$.
