Evaluate 8x2 + 9x − 1 2x3 + 3x2 − 2x dx. solution since the degree of the numerator is less than the degree of the denominator, we don't need to divide. we factor the denominator as 2x3 + 3x2 − 2x = x(2x2 + 3x − 2) = x(2x − 1)(x + 2). since the denominator has three distinct linear factors, the partial fraction decomposition of the integrand has the form† 8x2 + 9x − 1 x(2x − 1)(x + 2) = correct: your answer is correct. to determine the values of a, b, and c, we multiply both sides of this equation by the product of the denominators, x(2x − 1)(x + 2), obtaining 8x2 + 9x − 1 = a correct: your answer is correct. (x + 2) + bx(x + 2) + cx(2x − 1).

Hree experiments investigating the relation between need for cognitive closure and persuasion were performed. part of the study involved administering a "need for closure scale" to a group of students enrolled in an introductory psychology course. the "need for closure scale" has scores ranging from 101 to 201. for the 82 students in the highest quartile of the distribution, the mean score was x = 178.70. assume a population standard deviation of σ = 7.97. these students were all classified as high on their need for closure. assume that the 82 students represent a random sample of all students who are classified as high on their need for closure. find a 95% confidence interval for the population mean score μ on the "need for closure scale" for all students with a high need for closure. (round your answers to two decimal places.)
