A rancher has a herd of black cows and red cows. In total he has 65 COWS. The number of black cows is 7 less than triple the number of red cows."
a. Write two equations with two
variables to represent the
information in the problem,
b. How many red cows does the
rancher have? How many black
cows are there?(Write the final
answer as a sentence.)

What is the y-coordinate of the solution of the system of equations? [tex]y = 2x + 14 \\ - 4x - y = 4[/tex]y=

Will give brainliest immeadeately true or false: the origin woud be included in the solution set for the inequality: y< 2x-5

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).
