A machine produces coins such that the probability of heads, p, follows a Beta distribution with parameters (α, β) = (1, 1). A coin produced by this machine is picked at random and tossed independently n times. Let Y be the number of heads.

1. (a) Find E[Y ].

2. (b) Write down the pmf for Y (your answer can include unevaluated integrals and

   combination numbers [aka “n choose m” symbols]).

Straws work on the principle of the outside atmospheric pressure pushing the fluid (for example water) up the straw after you have lowered the pressure at the top of the straw (in your mouth). Assuming you could create a perfect vacuum in your mouth, what is the longest vertical straw you could drink water from?

1.65 m

4.28 m

7.71 m

10.3 m

8)  How would this answer change if you were on a planet with a much lower atmospheric pressure?

increases

decreases

remains the same

9)  A block of wood (density 550 kg/m³) and a block of metal (density 2700 kg/m³) with equal volume are placed 1 m under water in a swimming pool. Which has a greater buoyant force on it?

the metal

the wood

they have the same buoyant force

10)  Which has a greater force of gravity on it?

the metal

the wood

they have the same force of gravity

11)  Compare the buoyant force to the force of gravity for each object.

In both cases the buoyant force is greater.

In both cases the force of gravity is greater.

For the metal, the buoyant force is greater; for the wood, the force of gravity is greater.

For the wood, the buoyant force is greater; for the metal, the force of gravity is greater.

12)  If they were taken to a depth of 10 m what would happen to the buoyant force on each (assume the density of water is constant and the objects are incompressible)?

they increase

they decrease

they remain the same

they would sink

they would float

they would stay right where the are!

For your main Discussion post, describe at least two typical adjusting entries a service-type business would need to record to bring account balances up-to-date. For your examples, one of the adjusting entries should be an accrual and another a deferral. You may use similar examples as those in your textbook and you may also research other typical adjusting entries for service-type companies. Be sure to address the following questions:

• What are the purposes of each of your example adjusting entries?
• Why are these adjusting entries required?
• What if the company does not record these adjusting entries? Would financial statements be accurate? Why or why not?
• Should the adjusting entries described be posted to the general ledger before preparing an adjusted trial balance? Why or why not?

Question 3:

Suppose that 1000 customers are surveyed and 850 are satisfied or very satisfied with a corporation’s products and services.

1. Test the hypothesis H₀: p = 0.9 against H₁: p ≠ 0.9 at α = 0.05. Find the p-value.
2. Explain how the question in part (a) could be answered by constructing a 95% two-sided confidence interval for p.

Please provide an example of how MC.sim in R is to be used. The data can be made up, but please provide steps and explanations what to plug into that function. Thanks.

Java question:

Explain how class (static) variables and methods differ from their instance counterparts. Give an example of a class that contains at least one class variable and at least one class method. Explain why using a class variable and method rather than an instance variable and method would be the correct choice in the example you select.

Select the correct statement(s) regarding TCP.

select any five bones in the body and provide the following for each:

• A locational description using proper regional AND directional terminology

• An identification of a synovial joint this bone is a part of and a description of any features of that bone that are associated with the identified joint

• A description of the movement that is possible at the identified joint

(e.g. – The occipital bone of the skull is found in the posterior, inferior portion of the cranial cavity. It articulates with the atlas at the atlanto occipital joint. The occipital condyles of the occipital bone articulate with the superior articular facets of the atlas (or C1 vertebra). The atlanto occipital joint consists of two condyloid (or ellipsoid) synovial joints, allowing flexion and extension and a small amount of lateral flexion.)

How many total atoms are in 0.900 g of P2O5?

1. For the following reaction, 4.52 grams of oxygen gas are mixed with excess butane (C₄H₁₀). The reaction yields 3.09 grams of carbon dioxide.

butane (C₄H₁₀) (g) + oxygen (g) ----> carbon dioxide (g) + water (g)

2. For the following reaction,  5.60 grams of  chlorine gas are mixed with excess phosphorus (P₄) . The reaction yields  4.90 grams of  phosphorus trichloride .

phosphorus (P₄) ( s ) +  chlorine ( g ) ----> phosphorus trichloride ( l )

Given the vectors A= 2.00i + 6.00j and B= 3.00i - 2.00j, (a) draw the vector sum C= A + B and the vector difference D = A - B. (b) Calculate C and D in terms of unit vectors. (c) Calculate C and D in terms of polar coordinates, with angles measured in respect to the positive x-axis.

Parking Tickets – The Chicago police department claims that it issues an average of only 60 parking tickets per day. The data below, reproduced in your Excel answer workbook, show the number of parking tickets issued each day for a randomly selected period of 30 days. Assume σ =13.42.   State the null and alternate hypotheses, as well as the claim, which (hint!) is in the null hypothesis. Is there enough evidence to reject the group’s claim at α = .05?   (As with all of these exercises, use the P-value method, rounding to 4 digits.) (Hint: so since we know the population standard deviation, use the standard normal distribution z-test .) (Monday class)

                                                            Digital Clock with LCD Display

write the code for the function header:

#include "mbed.h"

#include "TextLCD.h"

1. In this lab, you will redo a digital clock this time with the LCD display and in the format of HH:MM:SS (HH is the hour from 0 -- 23, and MM is the minute from 00 -- 59, and SS is the second from 00-59)

2. Design the circuit that properly connects the LCD display to the mbed platform. Include your connection diagram in the Experiment Results of your lab report.

3. Based on the hardware design from step 2, design your code to implement the digital clock. Upon reset of the board, the clock should reset to 00:00:00, then changed to 00:00:01 after 1 second, and 00:00:02 after another second, etc.

4. Test your digital clock with an accurate clock (e.g. the clock in the computer). Explain the test process and what you observe while carrying out the test process. Is your digital clock accurate? If it is not, explain what you think might be the cause of the inaccuracy. "Calibrate" your digital clock by modifying your code to be as close to the accurate clock as possible. Include the details of your calibration process in your lab report.

I am more interested in the coding. Thanks
