(c) which interval gives a larger average rate of change, [40, 50] or [40, 80]? [40, 50] [40, 80] correct: your answer is correct. (d) compute f(40) − f(0) 40 − 0 . -15/3 incorrect: your answer is incorrect. what does this value represent geometrically? the slope of the line segment from (0, f(0)) to (40, f(40)) the slope of the tangent line at (0, f(0)) the slope of the tangent line at (20, f(20)) the slope of the tangent line at (40, f(40)) correct: your answer is correct. need ? read it

Use mathematical induction to prove the statement is true for all positive integers n, or show why it is false. 1^2 + 4^2 + 7^2 + + (3n - 2)^2 = [n(6n^2-3n-1)/2]

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.
