A random sample of residents of a city were asked whether they were satisfied with the city's public transportation system. The survey resulted in a sample proportion of p ′ =0.4 , with a sampling standard deviation of σ p ′ =0.07 .

If the graphs of the linear equations in a system are parallel, what does that mean about the possible solution(s) of the system? a. there are infinitely many solutions. b. there is no solution. c. there is exactly one solution. d. the lines in a system cannot be parallel.

Use the quadratic formula to solve the equation. if necessary, round to the nearest hundredth. x^2 - 8 = -6x a. –7.12, 1.12 b. 7.12, –1.12 c. 7.12, 1.12 d. –7.12, –1.12
