A girl of mass, m = 40 kg has osteoporosis which weakens her bones. From a kneeling position, she topples forward onto her elbows with her upper arms extended vertically downwards on impact with the ground. In falling forward, her centre of mass lowers by a height, h = 50 cm and she absorbs all of her kinetic energy from her fall into her two humerus bones (one bone in each upper arm).

Determine an equation for the stress in each humerus bone, ?, in terms of m, h, the acceleration due to gravity, g, Young’s modulus for bone, Y, the cross sectional area of each humerus bone, A and the length of each humerus bone, l. State any laws used. Now, determine the minimum rupture strength required for the girl’s humerus bones such that she doesn’t break them, given in units of N/m2 . Take l = 20 cm, A = 3.0 cm2 and Y = 1.4 x10^10 N/m2 .

1. In a repressible operon transcription is normally turned off.

2) A Monoybrid cross involves one gene and two or more different alleles.

3) Crossing over during meiosis occurs in the Metaphase II stage.

4) In prokaryotes, transcription and translation are separated in time and space.

5) Crossing over takes place in meiosis and is responsible for recombination.

6) Natural selection can lead to a decrease in genetic variation both within and between populations.

7) The pyrimidine bases in nucleic acids are adenine and guanine.

8) The poly(A) tails on mRNA molecules are transcribed from DNA templates.

9) Exons are degraded in the nucleus. 10) Most DNA binding motifs, such as leucine zippers, and Zinc fingers, have the binding the major groove of DNA. site in

For the data below perform a Wilcoxon Rank-Sum Test by-hand showing all steps (you may verify your results using software if you want to but it’s not required). 
Two treatments were developed for asthma patients. Twelve patients were randomly assigned to one of Treatment A or Treatment B (six patients on each treatment). The response variable is the number of days that the patients were symptom free after using their assigned treatments for a week. Test to see if Treatment A has a distribution that is shifted to the right (i.e. tends to have larger values) than Treatment B. 
Show all steps of your test and use 5% level of significance.

I am supposed to read chapt. 7 and 8 about bond valuation and risk this week . My assignment due wed is this . .. To prepare for this Discussion, consider your organization or one with which you are familiar, and its current riskiness. Develop an idea for a new product or service that has the potential to generate a good return on investment at reasonable or even high stand-alone risk but that has an opportunity to lower the organization's overall risk. Develop an argument as to why your suggested project has the potential to reduce the organization's overall risk. Be sure to identify at least two risk measurement tools used in the readings that you would deploy to measure the overall risk in the organization, and explain why your choices are appropriate for the situation. I'm not sure what he wants.. can anyone help

Person1, Person2, and Person3 all play on the Lacrosse Team and have an upcoming game. If none of them play in the game, their team will win by 5 points. If exactly one of person1, person2, or person3 plays, their team will win by 6 points, if exactly two of them play, their team will win by 7 points, and if all three play, their team will win by 8 points.

The probability that person1 plays is 3/10, as is the probability that person2 plays and the probability that person3 plays. The probability that person1 plays if person3 plays is 1/2. The probability that person2 plays if person3 plays is 1/3. The probability that person2 plays if person1 plays is 4/10. The probability all three play is 1/20.

Find the expected value, variance, and standard deviation of the number of points they will win by.
