Twenty years ago, 53% of parents of children in high school felt it was a serious problem that high school students were not being taught enough math and science. A recent survey found that 325 of 850 parents of children in high school felt it was a serious problem that high school students were not being taught enough math and science. Do parents feel differently today than they did twenty years ago? Use the a = 0.05 level of significance. Because npo (1-Po) = 211.7 10, the sample size is less than 5% of the population size, and the sample %3D can be reasonably assumed to be random, the requirements for testing the hypothesis are satisfied. (Round to one decimal place as needed.) What are the null and alternative hypotheses? 0.53 versus H;: Ho: (Type integers or decimals. Do not round.) 0.53 Find the test statistic. Z0 = - 8.63 (Round to two decimal places as needed.) Find the P-value. P-value = (Round to three decimal places as needed.)

Consider the following. The variable y varies directly as x, and y = 80 when x = 48. Write the equation that expresses the relationship between the variables. (Let k represent the variation constant.) y =     Using the given data, solve for the variation constant k. k =

olve the following equations. Logs (x) = 3 Round your final answer to two decimal places).

Determine the positive x solution for the following equation. x³ = 1,000,000
