7choose a number b at random from the interval [0, 1] with uniform density. find the probability that (a) 1/3 < b < 2/3. (b) |b − 1/2| ≤ 1/4. (c) b < 1/4 or 1 − b < 1/4. (d) 3b2 < b

What is the average rate of change for this function for the interval from x=2 to x=4 ?

Use the ratio test to determine whether ∑n=14∞n+2n! converges or diverges. (a) find the ratio of successive terms. write your answer as a fully simplified fraction. for n≥14, limn→∞∣∣∣an+1an∣∣∣=limn→∞.
