Consider a population proportion p = 0.20. [You may find it useful to reference the z table.]

a. Calculate the standard error for the sampling distribution of the sample proportion when n = 20 and n = 58? (Round your final answer to 4 decimal places.)

20=0.0894

58= 0.0525

b. Is the sampling distribution of the sample proportion approximately normal with n = 20 and n = 58?

c. Calculate the probability that the sample proportion is between 0.18 and 0.20 for n = 58. (Round "z-value" to 2 decimal places and final answers to 4 decimal places.)

3.     Calculate a numerical value for net filtration pressure in the glomerulus under each of the following conditions. Don’t forget to include units with each answer.

        a. At the afferent end of the glomerular capillaries: glomerular capillary blood (hydrostatic or hydraulic) pressure is 60 mm Hg; hydrostatic (hydraulic) pressure in Bowman’s capsule is 15 mm Hg; oncotic pressure in the glomerular capillaries at the afferent end is 21 mm Hg; and oncotic pressure in Bowman’s capsule is 0 mm Hg. Please show your work.

        b. Does your answer to the above question indicate that filtration or reabsorption is occurring across the glomerular capillaries at their afferent end?

        c. At the efferent end of the glomerular capillaries: glomerular capillary blood (hydrostatic or hydraulic) pressure is 58 mm Hg; hydrostatic (hydraulic) pressure in Bowman’s capsule is 15 mm Hg; oncotic pressure in the glomerular capillaries at the efferent end is 33 mm Hg; and oncotic pressure in Bowman’s capsule is 0 mm Hg. Please show your work.

        d. Does answer to the above question indicate that filtration or reabsorption is occurring across the glomerular capillaries at their efferent end?

        e. What is the average net filtration pressure across the glomerular capillaries in the above 2 problems? Show your work and include units.

In the drawing, the rope and the pulleys are massless, and there is no friction. The larger block has a mass of 10.03kg and the smaller block has a mass of 3.85kg.

Hyrdrofluoric acid (Ka = 7.2 x 10^-4), is used in a wide range of commercial processes. HF is used for glass etching and the synthesis of pharmaceutical drugs and compounds such as teflon. One issue with HF is its corrosive nature, "Aqueous hydrofluoric acid is a contact-poison with the potential for deep, initially painless burns and ensuing tissue death." (from Wikepedia page on hydrofluoric acid).

The flouride ion is often used in dental procedures, as the F- can react with tooth enamel to form highly stable mineral fluorohydroxyapatite (which is less likely to break down in the mouth than "normal" enamel). One common form of F^- delivery is fluoride varnish, which has a F^- concentration of around 1.778 M.

Given what you know of the acid base chemistry of HF, what is the concentration of HF in an aqueous solution with a pH of 5.85?

Write a C program to take two integer arrays in ascending order and combine them in a new array in descending order. Remove any duplicates in the final array, if any. Your code must store the arrays as a linked list of objects, each put in a “struct.” All operations should also be carried out using linked lists.

Input: 2 sorted arrays, each on a new line.

Output: An array sorted in descending order, without duplicates.

There is a single white space after each number, even after the last number. There is no new line at the end. Use the following struct as a reference:

struct ELEMENT {

int value;

struct ELEMENT *next;

};

1.Read the Lab6-Background.pdf first.2.Start the “Stack Queue” applet.3.The purpose of this exercise is to see how you could reverse a list of names. Push the three names “Alice,” “Bob,” and “Charles” onto the stack. When you pop the stack 3 times, what do you see in the text field next to “Pop”?4.Write an algorithm in pseudo-codethat would describe how to use a stack to reversea sequence (list)of letters and print them. For instance, if the original sequence is COMPUTERthe output will be RETUPMOC. Review pages 249-250 of the textbook(Chapter8)to see the related sample pseudo-codes.5.A palindrome word is one that has the same sequence of letters if you read it from right to left or left to right(e.g., radar or madam). Describe (in terms of a pseudo-code) how you could use a stack in conjunction with the original listto determine if a sequence is a palindrome.Hint:Given that the letters have been already assigned to both stackand the queueand these two data structures are ready to be processed (compared).

A spaceship leaves the earth, starting from rest and accelerating at a constance rate of 10m/s^2. its destination is the Moon, 380,000 km from earth. ignore size of earth and moon. Assume that both are at rest.

a.) At this rate of acceleration how long will it take the spacecraft to reach the moon?

for part b assume the spaceship accelerates to a halfway point (same acceleration as a)and then begins to deccelerate to have a final velocity of 0 when it reaches the moon.

b.) With the new method how long will it take for the spaceship to reach the moon?

the spaceship is carrying a probe which it can launch ouot of the front end of the spacecraft with a speed of 5000 m/s with respect to the spaceship.

c.) Assume the spaceship is traveling the same way as part b, at what distance from the moon should the probe be launched so that it will reach the moon at the same time as the saceship?

suppose the spaceship also has a probe that it can launch in the backward direction at the same speed of 5000 m/s with respect to the ship.

d.) In this case what distance from the moon should the probe be launched so that it will reach the moon at the same time as the ship?
