Anewspaper publisher trying to pin-point his market’s characteristics wondered whether the way people read a newspaper is related to the reader’s educational level. a sur-vey asked adult readers which section of the paper they read first and asked to report their highest educational level. these data were recorded (column 1 = first section read where 1 = front page, 2 = sports, 3 = editorial, and 4 = other) and column 2 = educational level where 1 = did not complete high school, 2 = high school graduate, 3 = university or college graduate, and 4 = postgraduate degree). what do these data tell the publisher about how edu-cational level affects the way adults read the newspaper?

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).
