What is a first-class function? Provide two scenarios where you would implement this concept.

Consider the following propositions: p: You get an A on the final exam. q: You do every exercise assigned in this course. r: You get an A in this class. (a) Translate the statement “You will get an A in this class if you do every exercise assigned in this course or you get an A on the final.” to propositional logic, using p, q, and r. (b) Write the truth table for the statement you wrote in (a). Is the statement a tautology? If not, provide a counter example. (c) What is the negation of the statement you wrote in (a)? (d) Write the truth table for the negation. For what combination(s) of values of p, q, and r is the negation true?

A. An unknown radioactive substance has a half-life of 3.20hours . If 10.6g of the substance is currently present, what mass A0 was present 8.00 hours ago?

B. Americium-241 is used in some smoke detectors. It is an alpha emitter with a half-life of 432 years. How long will it take in years for 45.0{\rm \\%} of an Am-241 sample to decay?

C. A fossil was analyzed and determined to have a carbon-14 level that is 20{\rm \\%} that of living organisms. The half-life of C-14 is 5730 years. How old is the fossil?

i need a thesis statement for gender inequality that is arguable, and has three supporting arguments

it can be about wage gap, women sexual harrasment, patriachy

this was mine but i wasnt sure if its arguable and is good

Discriminatory challenges for women start in childhood as young girls may believe that they are only suitable for certain professionals or in some cases, only for women and mothers. These consistent messages might lead to a false belief that women are not part of the corporate environment. Gender lines were drawn early, and women's exclusion persisted during adulthood. In this paper I will argue that women are discriminated in society. I will illustrate this by explaining women's sexual abuse on a daily basis, the hierarchical roles in which they engage in and the wage gaps, and women's experience in authority are seen as less important.

Show that Boruvka's algorithm has O(lgV) iterations.

The following objects are released simultaneously from rest at the top of a 1.35m long ramp inclined at 3.10 degrees to the horizontal: a solid sphere, a solid cylinder, a hollow cylindrical shell, and a hollow ball.

Which wins the race? The solid Sphere won, I just cant get the positions of the other 3 objects

At the moment the winner reaches the bottom, find the positions of the other three objects.

please explain....

Why might CPI not accurately measure real changes in the cost of living? (Discuss
substitution bias, introduction of new goods, changes in quality). Would CPI
overestimate or underestimate cost of living because of the bias?

Siders Breakfast Foods Inc., produces a popular brand of raisin bran cereal. The package indicates it contains 25.0 ounces of cereal. To ensure that the firm makes good in its marketing promo claim regarding box weight content, the Siders inspection department makes hourly check on the production process. As part of the hourly check, four boxes are selected and their contents weighed. The results for 25 samples are reported below.

1. Develop the appropriate control charts to evaluate and monitor the boxing process (10 pts)
2. What do the control charts tell you about the process during the 25-hour inspection period (i.e. Do a thorough interpretation and analysis of the charts.)? (10 pts)

3. An FDA regulation controlling the contents of packaged food items states that no more than 5 percent of the items produced and sold can contain less than 95 percent of the stated/labeled weight. Assuming that the standard deviation of the process, when in control or is operating as expected, is 0.90, determine if Siders Breakfast Foods, Inc., is in compliance or not in compliance with the FDA regulation given these parameters, i.e. process mean of 25 ounces and standard deviation of 0.90. Explain and show evidence supporting your conclusion. (10 pts). What should Siders Breakfast do if they discover their process to be in violation of the Federal regulation? (5 pts)

   (Assume that the content weight follows the normal distribution).

A block of wood has a mass of 3.54 kg and a density of 588 kg/m3. It is to be loaded with lead (1.13 × 104 kg/m3) so that it will float in water with 0.887 of its volume submerged. What mass of lead is needed if the lead is attached to (a) the top of the wood and (b) the bottom of the wood?

Brazil's environmental record is a real paradox. On the one hand it resembles so many other countries desperately trying to get ahead economically - even at the expense of its environment. On the other hand, Brazil is showing the world how to reduce fossil fuel use with associated benefits (mostly) of using sustainable biofuels.

What do you make of this seemingly contradictory record on the environment and which path do you think Brazil is more likely to take in the future ... and why?
