Quick! what is the area of this trapezoid?

How do you create a data set with 8 points in it that has a mean of approximately 10 and a standard deviation of approximately 1?

Asmall business produces and sells balls. the fixed costs are $20 and each ball costs $4.32 to produce. each ball sells for $8.32. write the equations for the total cost, c, and the revenue, r, then use the graphing method to determine how many balls must be sold to break even.
