A company produces very unusual CD's for which the variable cost is $ 20 per CD and the fixed costs are $ 30000. They will sell the CD's for $ 49 each. Let x be the number of CD's

produced.

Write the total cost C as a function of the number of CD's produced.

C= $

Write the total revenue R as a function of the number of CD's produced.

R= $

Write the total profit P as a function of the number of CD's produced.

P= $

Find the number of CD's which must be produced to break even.

The number of CD's which must be produced to break even is no

If g^-1(x) is the inverse of g (x) which statement must be true

Each of the following data sets has a mean of x = 10. (i) 8 9 10 11 12 (ii) 7 9 10 11 13 (iii) 7 8 10 12 13 (a) without doing any computations, order the data sets according to increasing value of standard deviations. (i), (iii), (ii) (ii), (i), (iii) (iii), (i), (ii) (iii), (ii), (i) (i), (ii), (iii) (ii), (iii), (i) (b) why do you expect the difference in standard deviations between data sets (i) and (ii) to be greater than the difference in standard deviations between data sets (ii) and (iii)? hint: consider how much the data in the respective sets differ from the mean. the data change between data sets (i) and (ii) increased the squared difference îł(x - x)2 by more than data sets (ii) and (iii). the data change between data sets (ii) and (iii) increased the squared difference îł(x - x)2 by more than data sets (i) and (ii). the data change between data sets (i) and (ii) decreased the squared difference îł(x - x)2 by more than data sets (ii) and (iii). none of the above
