A utility company burns coal to generate electricity. The cost of removing a certain percent of the pollutants from the smokestack emissions is typically not function. That isif it costs C dollars to remove 25% of the pollutants. would cost more than dollars to remove 50% of the pollutants. As the percent of removed pollutants approaches 100 %, the cost tends to become pro . Suppose that the cost C (in dollars) of removing p % of the smokestack pollutants

Two parallel lines are crossed by a transversal.what is value of x

What is the expression in factored form? 3x^2 + 18x + 24 a. 3(x+2)(x+4) b. 3(x-2)(x+4) c. 3(x-2)(x-4) d. 3(x+2)(x-4)

The null and alternate hypotheses are: h0: μ1 ≤ μ2 h1: μ1 > μ2 a random sample of 22 items from the first population showed a mean of 113 and a standard deviation of 12. a sample of 16 items for the second population showed a mean of 99 and a standard deviation of 6. use the 0.01 significant level. find the degrees of freedom for unequal variance test. (round down your answer to the nearest whole number.) state the decision rule for 0.010 significance level. (round your answer to 3 decimal places.) compute the value of the test statistic. (round your answer to 3 decimal places.) what is your decision regarding the null hypothesis? use the 0.01 significance level.
