In a hypothetical study, a pharmaceutical company is interested in finding the dosage of a new medication that best treats panic attacks. ninety people, who are diagnosed with panic attacks, were randomly assigned to three groups: (1) 20 milligrams of the new drug, (2) 30 milligrams of the new drug, and (3) 40 milligrams of the new drug. after 30 days on the medication, each participant records the number of panic attacks they have experienced in the previous seven days. what hypothesis testing technique should the researcher use to analyze the data? a) anovab) z-test for the population meanc) two-sample t-testd) paired t-test

What is the result of the following division?

3x = 729 solve for x plz . it's urgent. will mark

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).
