ards, where a face card is a Jack, a Queen, or a King, in succession from a standard deck of 52 cards without replacing the first card, you win $10. Otherwise, you pay your friend $20. If the same bet was made 15 times, how much would you expect to win or lose? Round your answer to the nearest cent, if necessary.

ction between the floor and book is µk. Using the information given in the figure: (a) draw free body diagrams for both the books, and also for the combined system (of mass m1+m2), (b) find acceleration of the books along horizontal direction, and (c) find the magnitude and direction of the force exerted by the left book on the right book. 3.A car of mass 1500-kg enters a circular path at point P and leaves at point Q (see the figure) at constant speed of 5.0m/s, and the frictional force acting on its tires is 2500-N. a) how long it takes to reach point Q from point P, and b) what should be the minimum value of the coefficient of static friction between the tires and the road? 4)In an elevator which is accelerating downward at 2.5ms−2 , a 25-kg block hangs from a spring attached to the ceiling of the elevator. If spring gets stretched by 0.15m, find its spring constant.

two objects and recorded whether or not the dog being tested correctly chose the object indicated. A four-year-old male beagle named Augie participated in this study. He chose the correct object 42 out of 70 times when the experimenter leaned towards the correct object. (a) (2 points) Let the parameter of interest, π, represent the probability that the long-run probability that Augie chooses correctly. Researches are interested to see if Augie understands human body cues (better than gussing). Fill in the blanks for the null and alternative hypotheses. H0 : Ha : (b) (6 points) Based on the above context, conduct a test of significance to determine the p-value to investigate if domestic dogs understand human body cues. What conclusion will you draw with significance level of 10%? (If you use an applet, please specify which applet you use, and the inputs.) (c) (5 points) Based on the above context, conduct a test of significance to determine the p-value to investigate if domestic dogs understand human body cues. What conclusion will you draw with significance level of 5%? (If you use an applet, please specify which applet you use, and the inputs.) (d) (2 points) Are your conclusions from part (b) and (c) the same? If they are different, please provide an explanation. (e) (5 points) Shown below is a dotplot from a simulation of 100 sample proportions under the assump- tion that the long-run probability that Augie chooses correct is 0.50. Based on this dotplot, would a 90% confidence interval for π contain the value 0.5? Explain your answer. (f) (4 points) Compute the standard error of the sample proportion of times that Augie chose the object correctly. 1 (g) (5 points) (h) (3 points) question? (i) (4 points) (j) (4 points) A. B. C. Construct an approximate 95% confidence interval for π using the 2SD method. What is the margin of error of the confidence interval that you found in the previous How would you interpret the confidence interval that you found in part (g)? Which of the following is a correct interpretation of the 95% confidence level? If Augie repeats this process many times, then about 95% of the intervals produced will capture the true proportion of times of choosing the correct objective. About 95% times Augie chooses the correct objective. If Augie repeats this process and constructs 20 intervals from separate independent sam- ples, we can expect about 19 of those intervals to contain the true proportion Augie chooses the correct objective. (k) (4 points) object 21 out of 35 times. Conjecture how, if at all, the center and the width of a 99% confidence interval would change with these data, compared to the original 2SD 95% confidence interval.

rts to the fireworks platforms: one part is on the ground and the other part is on top of a building. You are going to graph all of your results on one coordinate plane. Make sure to label each graph with its equation. Use the following equations to assist with this assignment. • The function for objects dropped from a height where t is the time in seconds, h is the height in feet at time it t, and 0 h is the initial height is 2 0 ht t h ( ) 16 =− + . • The function for objects that are launched where t is the time in seconds, h is the height in feet at time t, 0 h is the initial height, and 0 v is the initial velocity in feet per second is 2 0 0 ht t vt h ( ) 16 =− + + . Select the link below to access centimeter grid paper for your portfolio. Centimeter Grid Paper Task 1 First, conduct some research to help you with later portions of this portfolio assessment. • Find a local building and estimate its height. How tall do you think the building is? • Use the Internet to find some initial velocities for different types of fireworks. What are some of the initial velocities that you found? Task 2 Respond to the following items. 1. While setting up a fireworks display, you have a tool at the top of the building and need to drop it to a coworker below. a. How long will it take the tool to fall to the ground? (Hint: use the first equation that you were given above, 2 0 ht t h ( ) 16 =− + . For the building’s height, use the height of the building that you estimated in Task 1.) b. Draw a graph that represents the path of this tool falling to the ground. Be sure to label your axes with a title and a scale. Your graph should show the height of the tool, h, after t seconds have passed. Label this line “Tool”.

tarting the process of meiosis. Draw the chromosomes, depicting them inside the cell, as you would expect them to appear during Metaphase I. (Note: there is more than one correct answer for this prompt. You only need to draw one of the answers.) 2.How many copies of gene A are present in this parent cell during Metaphase I? 3.How many total chromosomes would you have after DNA replication (synthesis)? 4.While examining a specific tissue in this organism, Bridget noticed some cells with more than one nucleus (this is commonly found in many species, including humans!). What could have happened during the process of cell division to yield these multinucleate cells? 5.In one of her harebrained experiments, Dr. Milam remembers treating some cells from one of her organisms with a drug that resulted in the cell being unable to replace RNA primers with DNA. Which protein in the cells was most likely affected by this drug treatment? 6.In another one of her experiments, Dr. Milam treated cells with a different drug that caused an adenosine in gene A to be paired with a cytosine instead of a thymine during DNA replication. However, Dr. Milam remembers that the amino acid sequence of the protein product of gene A wasn’t actually changed. How could you explain this observation?

exane ring with 2 substitutions, exactly 2 chiral centers and 3 units of unsaturation. then I have to pick one chiral stereoisomer from it, and circle chiral centers of it and assign (R/S) and how work for priority. then I have to do a chair flip of this stereoisomer, draw both conformers of the cyclohexane ring and show the more stable conformer between the two.

m 2 After graduating from AUD, Salman plans to start a book publishing company in the Media City. He did some research and found that the printer will cost Dh 230,000. He estimated that the variable cost per book is Dh 170 and the selling price is Dh 390. a. How many books must he sell to break even? Also calculate the breakeven in dirham. b. In addition to the costs given above, if he wants to pay himself a salary of Dh 15,400 per year, what is her breakeven point in units and dirham? c. In the first three months of his business, he sold 400 books. Suddenly the printer breaks down. He spent Dh 25000 to fix the printer. In addition to 400 books sold, how many more books she should sell to breakeven? Assume that this part of the question is independent, and she does not draw any salary. Problem 8 A furniture store makes tables and chairs from plywood and glass. The store has 30 units of plywood, 24 units of glass. Each table requires 7 units of plywood three units of glass, whereas each chair requires three units of plywood and two units of glass. The demand for chairs is between 2 and 4. The ratio between the table and chair is at least 1 to 2. A table earns $225 in profit and a chair, $145. The store also wants a minimum profit of $5000. The store wants to determine the number of tables and chairs to make in order to maximize profit. Formulate a linear programming model for this problem

f the students make their choices independently and each is as likely to pick one integer as any other, what is the probability that 8 or more will select 4,5 or 6? b Having observed eight students who selected 4, 5, or 6, what conclusion do you draw based on your answer to part (a)?A missile protection system consists of n radar sets operating independently, each with a probability of .9 of detecting a missile entering a zone that is covered by all of the units. a If n = 5 and a missile enters the zone, what is the probability that exactly four sets detect the missile? At least one set? b How large must n be if we require that the probability of detecting a missile that enters the zone be .999?

k of 10 cards numbered 1-10. I draw 5 cards (each time i draw i put the card back and shuffle). The numbers were 8, 2, 4, 9, and 4. What is the probability that it will be 4 on the 6th time i draw? I know each card has a 10% chance of being drawn. I also know the probability of a 10% event happening twice is 1%. But wouldnt the odds be lower since i drew 4 a couple trials earlier? How exactly would i calculate that. If there is an online calculator that executes the answer id like to know. Just a college student who craves probability. :)

e based on the provided data set. You can draw the tree electronically, or draw it by hand and scan or photograph a copy—or use any other appropriate means you wish. 2. How many homoplasies are in the tree? Give the nucleotide position number(s) and tell what character states were independently derived in which species. 3. Two major clades are revealed by the tree. List the species in each clade. What can you say in general about the geographic distribution of each clade? 4. In cases where two species of Map Turtle occupy the same river system, are those species each other’s nearest relatives? Considering their phylogeny and distribution, what speciation events (including such factors as migration, vicariance, etc.) would you predict led to the species found in these rivers and their current distributions?
