The government of an impoverished country reports the mean age at death among those who have survived to adulthood as 66.2 years. A relief agency examines 30 randomly selected deaths and obtains a mean of 62.1 years with standard deviation 8.1 years. Test whether there is enough evidence supporting the agencys claim, at the 1% level of significance, that the population mean is less than 66.2. Q6/ Two cables BC & BD are pull out the ship as shown in Fig. (6), if the diameter of each cable is 50 mm, determine the normal stress in each cable? (12 marD Fig. (6) NTOS Write an equation for a parabola given the coordinates of thefocus F(-1; -2) and the directrix equation x - y + 8 = 0 A pulsar is a rapidly rotating neutron star that emits radio pulses with precise synchronization, there being one such pulse for each rotation of the star. The period T of rotation is found by measuring the time between pulses. At present, the pulsar in the central region of the Crab nebula has a period of rotation of T = 0.07000000 s, and this is observed to be increasing at the rate of 0.00000268 s/y. What is the angular velocity of the star? What is the angular acceleration of the pulsar? If its angular acceleration is constant, in how many years will the pulsar stop rotating?The pulsar originated in a super-nova explosion in the year A.D. 1054. What was the period of rotation of the pulsar when it was born? Find the truth table of each proposition. 1. (pq)v(pq) 2. [p(qr)][q(pr)] 3. [r(pq)](rq) 4. [(pq)(r(p)](rq) 5.

Gail has interest income totaling $245,000 and she pays property taxes and home mortgage interest totaling $30,000.a. What filing status applies to Gail?b. Compute her taxable income and gross tax.c. Assume that Gail does not have a daughter. What is Gail's filing status? ABC Country has 1105414 unemployed, a labor force of 4214785 and a working age population of 6802730 . What is the labor force participation rate for ABC Country? The windshield wipers on a car have not been working properly. The probability that the car needs a new motor is 0.6, the probability that the car needs a new switch is 0.4, and the probability that the car needs both is 0.25. What is the probability that the car needs neither a new motor nor a new switch? The probability that the car requires needs neither a new motor nor a new switch is (Type an integer or a decimal.)

Why are groins and jetties rarely beneficial to the coastalsystem they are designed to protect? Be specific in youranalysis Explain the tension and paradox of why Managing change is not asimple task? Which of the following statements is TRUE of qualitative research? Samples for qualitative studies are large and do not require participants to be screened based on important attributes. With a qualitative study, detalled, rich data is usually collected by atking general, open-ended questlons. Findings from qualitative data are generafizable to the population as a whole, informing a marketing manager's final strategle dedslon. Conducting a qualitative study prevents researchers from probing more deeply into areas such as subconscious, psychological consumer motivations. Qualitative study designs are typically informed/influenced by findings from quantitative research. In evaluating your secondary data sources, you are sure to check your news sources to make sure they come from reputable onganizations and that they do not feature sponsored content. This is in keeping with which evaluation criterla discussed in class? Consistency Methodology Purpose Influence Credibility Which of the following is true of independent variables? Their values remain constant throughout an experiment. They do not affect the outcome of an experiment. They are also called criterion variables. Their values are directly manipulated by a researcher. Their values change only with changes in the values of dependent variables. When researchers perform a they gather and synthesize background information, as well as internal and external secondary data to famillarize themselves with the overall complexity of the problem. Data check Background check Situation analysis Theory definition Anatomy screening Which of the following is true of marketing research? It is exclusively used by large businesses. It was originally developed to manage the activities in a supply chain to maximize product value. It solely relies on quantitative techniques. It draws heavily on the social sciences both for methods and theory. It solely relies on observational techniques. Traditional organizations have historically organized workers together for communication purposes and coordinated the Stern School of Business's Center for Digital Economy Research Working Paper IS-93-48. In contrast to a physical presence, IT design variables allow for a virtual organizational structure.Discuss the ideas in this scientific paper Find the polar equation of a hyperbola with eccentricity 2and directrix y = 5Select the correct answer below:r = 10/(1 - 2cos theta)r = 10/(1 + 2cos theta)r = 10/(1 - 2sin theta)r = 10/(1 + 2sin theta) The following is the balance sheet of Korver Supply Company at December 31, 2020 (prior year). Transactions during 2021 (current year) were as follows: Additional information: The notes payable are dated June 30,2020 , and are due on June 30,2022 . Interest at 6% is payable annually on June 30 . Depreciation on the furniture and fixtures for 2021 is $20,000. The furniture and fixtures originally cost $300,000. Required: Prepare a classified balance sheet at December 31, 2021, by updating ending balances from 2020 for transactions during 2021 and the additional information. The cost of furniture and fixtures and their accumulated depreciation are shown separately. (Amounts to be deducted should be indicated by a minus sign.) furniture and flxtures for 2021 is $20,000.

You throw a ball straight up into the air. It takes you 0.850 s to accelerate the ball to 15.0 m/s at which point it leaves your hand. You catch it when it has a velocity of -15.64 m/s. It takes 0.450 seconds for the ball to come to a stop after it reaches your hand. a. Calculate the acceleration of the ball before it leaves your hand b. What is the acceleration of the ball after it leaves your hand and before you catch it? C. If the ball left your hand at 1.90 m above the ground what altitude did it reach? 2a-(5pts.)
