A tortoise and a hare were competing in a foot race. Because the hare knew he could run faster than his friend, he let the tortoise have a 15-meter head start. The system {y=15+3xy=5x can be used to model the race (x is the time, in seconds, since the race began, and y is the distance, in meters, from the starting line)

Use the grid provided to graph the system.

If you have the following equation, 2/3x+5/6-x=2-3/4x what would you multiply each term by to get rid of all the fractions

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).

What is the interquartile range of this data set? 2, 5, 9, 11, 18, 30, 42, 48, 55, 73, 81
