Wayne is solving a system of linear equations.

y = −34x + 5
x = −2

To solve this system, he graphed the line y = −34x + 5.

When Wayne graphs the line x = −2, at which point will he find the solution of this system of linear equations?

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).
