13 Which equation has (-2,-4) as a solution? a. y = 4x + 4
b. y = 3x - 8
c. y = -2x + 1
d. y = -4x - 4

What is the definition of exponential decay?

What are the solutions of the system? solve by graphing. y = x^2 + 3x + 2 y = 2x + 2

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).
