in a basketball game a referee throws the basketball upwards from an initial height of 2.00 meters above the floor, with sufficient initial speed such that its highest point will be 4.20 meters above the floor. a basketball players outstretched hand is 2.50 meters above the floor when he holds his hand above his head, and he can jump with an initial speed of 3.90m/s upwards. how long after the ball is released from the referees hand should the player jump in order to reachthe ball just as his highest point of his jump, if he is to do so (a) while the ball is still on its way up, and (b) when the ball is on its way back down?

Can you please use excel to answer this question. Please

1. The annual returns of three stocks for the past seven years are given in the following table:

1. Determine the average return and the standard deviation of returns for each stock. Which stock has the highest expected return and which one has the highest risk?
2. Determine the correlation coefficient and the covariance between each pair of stocks.

Look at how precipitation and evapotranspiration vary globally, and find out why. Both are parts of climate and weather and must be related to atmospheric and oceanic circulation patterns, latitude, distance from the ocean, topography, vegetation and perhaps other factors. Examine the global maps of evapotranspiration, precipitation, and temperature (http://quebec.hwr.arizona.edu/classes/hwr201/infographics/). Look also at topography, for example by using google maps with “terrain” option switched on, and maybe also at wind patterns, ocean currents etc. Required: (a) Where is precipitation highest? Lowest? (b) Where is evapotranspiration highest? Lowest? (c) Explain why (use all available information: precipitation, evapotranspiration, temperature, topography, geography, winds, circulation)

Describe three current routines used in a program to assist with classroom management.

1. Take time to do a physical assessment of your current teaching-learning space.
   • Draw a map (preferably to scale) showing the placement of permanent items.
   • Add arrows to suggest traffic flow.
   • Circle the areas of highest concentration of student activity during a typical working day.
   • Identify student's personal storage space.

After creating your map, write a brief description of your current teaching-learning space. Make sure you describe the placement of permanent items, the flow of traffic, areas of highest student concentration and students’ personal storage space

1. Note areas of improvement and a plan for change.

Course Name: Professional Communication

Required:

Make a good presentation

TOPIC: Corona Virus has impacted the entire world. UAE is no exception. And your Company is also no exception. Make a presentation to showcase how your Company or department managed the crisis. Assume you are presenting to the highest Council in UAE.

Note:

Start with deciding why you are making a presentation to the highest Council. Do you need some money to support your department because of the crisis? Do you need some other support from the Council? Or are you presenting how you have utilized the funds the government has given to your department?

Based on the objective you choose, make a presentation on the above topic.

Write a python program.
The function protocol implements the functionality of the diagnostic protocol. The main idea of this function is to call the functions that you
have already implemented in the previous questions. See below for an explanation of exactly what is
expected.
def protocol(my_symptoms: Tuple[Set], all_patients_symptoms: Dict[str, Tuple[Set]],
all_patients_diagnostics: Dict[int, str]) -> str:

'''Return the diagnostic for my_symptoms based on the dictionary of patients symptoms
(all_patients_symptoms) and the dictionary of patients diagnostics
(all_patients_diagnostics).
Hint: This function selects the patients with the highest similarity between the their
symptoms and my_symptoms (by calling the function similarity_to_patients). Then, it
reports the the most frequent diagnostic from the patients with the highest symptoms
similarity (by calling the function getting_diagnostics).
>>>protocol(yang, all_patients_symptoms, all_patients_diagnostics)
'cold'

The general social survey (GSS) is a yearly survey of adult US citizens on a variety of social issues. Over 5300 different questions have been asked over the nearly 40 years of administering the survey, with many of the questions, the same from year to year. Here are some of the questions asked:

i. Gender (Male/Female)

ii. Age (years)

iii. Highest Degree Earned (None, High School Diploma, Associate’s level, Bachelor’s level, Post-bachelor’s [MS, PhD, MD, etc.])

iv. Political Party (Republican, Democrat, Other)

v. Household yearly income ($’s)

For each of the following questions, indicate the most appropriate analysis to be used to test the research hypothesis. Choose one of the following strategies: ANOVA (comparing multiple group means), Independent Samples T-Test (comparing two group means), Correlation, Chi-squared Test (comparing two or more proportions), One proportion test

14. A relationship between Gender and Highest Degree Earned__________________

15. A relationship between Age and Income________________________

16. A relationship between Age and Highest Degree Earned____________________

17. A relationship between Political Party Affiliation and Income___________________

A(n) 8.0 ?%, ?25-year bond has a par value of? $1,000 and a call price of ?$1,100 . ?(The bond's first call date is in 5? years.) Coupon payments are made semiannually? (so use semiannual compounding where? appropriate).

a. Find the current? yield, YTM, and YTC on this? issue, given that it is currently being priced in the market at $ 1,225. Which of these 3 yields is the? highest? Which is the? lowest? Which yield would you use to value this? bond? Explain.

b. Repeat the 3 calculations? above, given that the bond is being priced at ?$875 . Now which yield is the? highest? Which is the? lowest? Which yield would you use to value this? bond? Explain.

a. If the bond is priced at ?$1,225 ?, the current yield is ___ ?%. ?(Round to two decimal? places.) The annual? yield-to-maturity with semiannual compounding is ___ ?%. ?(Round to two decimal? places.)

The annual? yield-to-call with semiannual compounding is ____ ?%. ?(Round to two decimal? places.) Which of these 3 yields is the? highest? Which is the? lowest???

Which yield would you use to value this? bond???(Select the best answer? below.)

A. The? yield-to-maturity because the bonds may not be called.

B. The? yield-to-maturity is always used.

C. It? doesn't matter which yield you use.
