(4) Let S = {a,b,c,d,e}. (a) List all of the 2-permutations of S in an organized manner. How many are there? (b) List all of the 2-combinations of S in an organized manner. How many are there? (c) List all of the 3-combinations of S in an organized manner. How many are there? (d) On the previous page, you should have gotten the same number of 2-combinations of S as 3-combinations. Explain why we should expect these numbers to be the same.

The edge roughness of a slit paper products increases as knife blades wear. Only 1% of products slit with new blades have rough edges, 3% of products shot with blades of average sharpness exhibit roughness, and 5% of the products slit with worn blades exhibit roughness. If 25% of the blades in manufacturing are new, 60% are of average sharpness, and 15% are worn blades.a. What is the proportion of products that exhibit edge roughness?b. If a paper was selected at random and found that it has rough edges, what is the probability that it was slit by a new knife blades?c. If a paper was selected at random and found that it has rough edges, what is the probability that it was slit with a blade of average sharpness blades or worn blades?

A store offers packing and mailing services to customers. The cost of shipping a box is a combination of a flat packing fee of $5 and an amount based on the weight in pounds of the box, $2.25 per pound. Which equation represents the shipping cost as a function of x, the weight in pounds?f(x) = 2.25x + 5f(x) = 5x + 2.25f(x) = 2.25x − 5f(x) = 5x − 2.25

5.8 Twitter users and news, Part I. A poll conducted in 2013 found that 52% of U.S. adult Twitter users get at least some news on Twitter.12. The standard error for this estimate was 2.4%, and a normal distribution may be used to model the sample proportion. Construct a 99% confidence interval for the fraction of U.S. adult Twitter users who get some news on Twitter, and interpret the confidence interval in context.

You calculated probabilities involving various blood types. Some of your answers depended on the assumption that the outcomes described were disjoint; that is, they could not both happen at the same time. Other answers depended on the assumption that the events were independent; that is, the occurrence of one of them doesn't affect the probability of the other. Do you understand the difference between disjoint and independent? a) If you examine one person, are the events that the person is Type A and that the same person is Type B disjoint , independent, or neither? b) If you examine two people , are the events that the first is Type A and the second Type B disjoint , independent, or neither? c) Can disjoint events ever be independent? Explain

What is the difference between a categorical and continuous variable? Group of answer choices Categorical is independent (explanatory); continuous is dependent (response). Categorical are subjective (based on researcher’s judgment); continuous are measured Categorical can be measured accurately; continuous have to be estimated. Categorical are assigned to discrete categories; continuous can take any value in a range.

The probability that the first stage of a numerically controlled machining operation for high-rpm pistons meets specifications is 0.90. Failures are due to metal variations, fixture alignment, cutting blade condition, vibration, and ambient environmental conditions. Given that the first stage meets specifications, the probability that a second stage of machining meets specifications is 0.95. What is the probability that both stages meet specifications?
