As a salesperson, brittany earns $1,200 a month plus 7.5% commission on her sales. she needs to earn at least $3,300 a month to pay all her bills. the following inequality can be used to find the amount of sales brittany needs to have each month. 1200+0.075x > 3300. what is the solution to the inequality? a. x< 28,000 b. x> 28,000 c. x< 33,750 d. x> 33,750

G(x)=x2-16xb=-16, so =16 = 649(x) = (x2 - 16x + 64) - 649(x) = (x - 1)2-

The graph shown is the graph of which function?

Atextile fiber manufacturer is investigating a new drapery yarn, which the company claims has a mean thread elongation of 12 kilograms with a standard deviation of 0.5 kilograms. the company wishes to test the hypothesis upper h subscript 0 baseline colon mu equals 12 against upper h subscript 1 baseline colon mu less-than 12 using a random sample of n equals 4 specimens. calculate the p-value if the observed statistic is x overbar equals 11.8. round your final answer to five decimal places (e.g. 98.76543).
