Alan company invests $500,000 in equity securities on April 30, 2016, and classifies them as trading securities. At December 31, 2016, the company’s year-end, the securities have a fair value of $495,000. On February 1, 2017, the company sells the securities for $520,000.

Which statement is true regarding how this information is reported in the company's financial statements?

a. The companies 2016 balance sheet reports the securities at $495,000, and gain of $20,000 is reported on the 2017 income statement.

b.The companys 2016 balance sheet reports the securities at $500,000 and no gain or loss appears in the 2016 financial statements.

c. The company 2016 balance sheet reports the securities at $500,000, and a loss of $5,000 is reported on the 2016 income statement.

d. The companys 2016 balance sheet reports the securities at $495,000, and a gain of $25,000 is reported on the 2017 income statement.

The following information is available for Quality Book Sales’ sales on account and accounts receivable: Accounts receivable balance, January 1, 2016 $ 79,500 Allowance for doubtful accounts, January 1, 2016 4,910 Sales on account, 2016 560,000 Collection on accounts receivable, 2016 566,000 After several collection attempts, Quality Book Sales wrote off $2,960 of accounts that could not be collected. Quality Book Sales estimates that 5 percent of the ending accounts receivable balance will be uncollectible. Required: a. Compute the following amounts: (1) Using the allowance method, the amount of uncollectible accounts expense for 2016. (2) Net realizable value of receivables at the end of 2016. b. Record the general journal entries to: (1) Record sales on account for 2016. (2) Record cash collections from accounts receivable for 2016. (3) Write off the accounts that are not collectible. (4) Record the estimated uncollectible accounts expense for 2016. (If no entry is required for a transaction/event, select "No journal entry required" in the first account field.)

1. Assume that you are conducting an experiment in human performance. You have two groups: experimental (the group that receives the treatment) and control (the group that does not receive the treatment). Briefly describe your experiment, your research hypothesis, and your null hypothesis.

2. Assume that you are conducting an experiment in human performance. You have two groups: experimental (the group that receives the treatment) and control (the group that does not receive the treatment). What steps would you take to make a decision about the effectiveness of your experimental intervention?

Hi there,

I want to make an experiment that you can use a one sample z- test and interval on it. The project is a paper helicopter and we can make as many we like and then explain the process It should be dropped from a height and a weight like paperclip in the bottom to make fall. Please help me with this project.

1st: what is inference procedure and the variables you are

estimating

2nd: the experiment procedure, the condition and how we can prevent bias

3rd. what kind of difficulties I could have on making such an experiment.

We want to determine spesifications of very toxic fuel especially the particle diameters. After some studying we claim that the particle diameter is dp, exit speed is U, the liquid viscosity is u, surface tension is Y, density is p, the diameter of spraying injector exit is D. For a secure experiment we need to work with water. Design an experiment with water and determine the required conditions. Finally, for toxic fuel use the results of experiment for determining spesifications (especially the partical diameter) with mathematical expressions use dimensionless numbers if needed.

According to an? airline, flights on a certain route are on time 80?% of the time. Suppose 13 flights are randomly selected and the number of? on-time flights is recorded. ?(a) Explain why this is a binomial experiment. ?(b) Find and interpret the probability that exactly 8 flights are on time. ?(c) Find and interpret the probability that fewer than 8 flights are on time. ?(d) Find and interpret the probability that at least 8 flights are on time. ?(e) Find and interpret the probability that between 6 and 8 ?flights, inclusive, are on time. ?(a) Identify the statements that explain why this is a binomial experiment. Select all that apply. A. There are two mutually exclusive? outcomes, success or failure. B. The trials are independent. C. The probability of success is the same for each trial of the experiment. D. There are three mutually exclusive possibly? outcomes, arriving? on-time, arriving? early, and arriving late. E. The experiment is performed a fixed number of times. F. Each trial depends on the previous trial. G. The experiment is performed until a desired number of successes is reached. ?(b) The probability that exactly 8 flights are on time is nothing. ?(Round to four decimal places as? needed.) Interpret the probability. In 100 trials of this? experiment, it is expected about nothing to result in exactly 8 flights being on time. ?(Round to the nearest whole number as? needed.) ?(c) The probability that fewer than 8 flights are on time is nothing. ?(Round to four decimal places as? needed.)
