While reviewing the March 31, 2020, balance sheet of Business Solutions, Santana Rey notes that the business has built a large cash balance of $68,146. Its most recent bank money market statement shows that the funds are earning an annualized return of 0.64%. S. Rey decides to make several investments with the desire to earn a higher return on the idle cash balance. Accordingly, in April 2020, Business Solutions makes the following investments in trading securities

On June 30, 2020, the fair value of the Johnson & Johnson bonds is $14,700 and the Starbucks notes is $3,700.

Required:
1. Prepare journal entries to record the April purchases of trading securities by Business Solutions.
2. On June 30, 2020, prepare the adjusting entry to record any necessary fair value adjustment to its portfolio of trading securities.

In java design and code a class named comparableTriangle that extends Triangle and implements Comparable. Implement the compareTo method to compare the triangles on the basis of similarity.

Draw the UML diagram for your classes.

Write a Driver class (class which instantiates the comparableTriangle objects) to determine if two instances of ComparableTriangle objects are similar (sample output below). It should prompt the user to enter the 3 sides of each triangle and then display whether or not the are similar triangle. (25 points)

Triangle Similarity: With the Triangle class we have already built, one that uses only side lengths, not angles, in its constructor, there is only one way we can check for similarity: side-side-side similarity. The definition of side-side-side similaritry is:

If all the sides of a triangle are proportional to the corresponding sides of another triangle then the triangles are said to be similar.

in other words: (Triangle1 side1 / Triangle2 side 1) = (Triangle1 side2 / Triangle2 side2) = (Triangle1 side3 / Triangle2 side3)

In a survey of 1118 U.S. adults conducted by the Financial Industry Regulatory Authority, 415 said they always pay their credit cards in full each month.

a) Construct a 95% interval for the population proportion of U.S. adults who pay their credit cards in full each month.

To show work, write out the following:
- The given numbers with their corresponding variables.

- The formula that's used to calculate the confidence interval. Also give a short explanation stating why you chose the formula that you did.

- The built in calculator program that you used to compute your answer.

b) Interpret you confidence interval from (a). Include the following:

- The confidence level.

- The population parameter of interest (in the context of the problem).

- The lower and upper bounds of the C.I., along with the units.

c) Based on your confidence interval from (a), is it true that a majority of U.S. adults always pay their credit cards in full each month? Explain why or why not using a complete sentence.

Binary Search Algorithm

a.) Create a Java application that utilizes the "Binary Search Algorithm" presented in chapter 19 (NOT Java's pre-built binarySearch() method from imported Java library) to search for an integer in a random array of size 30 in the range of 0 to 1000 inclusive. You should use Java's random number generator to randomize the numbers in your array.

b.) The application's main() method should display unsorted array and sorted array, prompt user for a search key, allow user to enter a search value from the keyboard, read in the user's keyboard entry, then perform binary search for the search key in the array after the array is sorted, then inform the user of the search result in the console by displaying a message indicating whether or not the value is found, if found, also display its index in the array. Note:binarySearch() for a value in an array require the array to be sorted first, before searching for any value in the array.

(Python)

Implement a function to compute a sum that can compute sum for an arbitrary number of input integers or float numbers. In other words, calls like this should all work:

flexible_sum(x1, x2) # sum of two integer or float numbers or strings x1 and x2

flexible_sum(x1, x2, x3) # sum of 3 input parameters

and can also handle a single input parameter, returning it unchanged and with the same type, i.e.:

  flexible_sum(1)

returns 1

and can accept an arbitrary number of strings as input parameters and return their concatenation. In other words, the following call

  flexible_sum('one ', 'two ', 'three ')

should give result string

  'one two three '

And the function can also accept a single input parameter in the form of a list of an arbitrary length and return a sum for it.

If you can, try to implement your function without calls to any other external functions, including Python built-in functions.

A realtor in Oregon found that the selling price (in thousand dollars) of the house and the age of the house (how long since it was built) was highly correlated (r=–0.6). She collected some data and derived the following regression model.

Y = 260 – 2.5X

(1) Given above information, what would be the expected selling price for a house that was build 20 years ago?

(2) If another house is 8 years newer than the one mentioned in (1), will be the selling price higher or lower, and by how much?

Select one:

a. (1) 210 thousand dollars; (2) 8 thousand dollars lower.

b. (1) 210 thousand dollars; (2) 8 thousand dollars higher.

c. (1) 310 thousand dollars; (2) 12 thousand dollars higher.

d. (1) 240 thousand dollars; (2) 20 thousand dollars lower.

e. (1) 210 thousand dollars; (2) 20 thousand dollars higher.

This task has the following elements that are relevant to the learning outcomes of this module: - use ArrayList to save, find, insert items - convert from an array to an ArrayList - shuffle a list using your own method, sort a list You should write a simple Java class that will perform some operations on an ArrayList Create an Integer array of ten objects that you initialize with values ​​1 to 10. Convert it to an ArrayList object. Add a number Remove one of the numbers in the list. Ask the ArrayList object if it contains added value and the value that was removed. Create a method (do not use built-in shuffle methods) to put the values ​​in a random order Arrange the array list in descending order and print it. Example of printing is:

Does list contain 42? Yes 
Does list contain 9? No 

4 2 5 1 0 3 8 7 6 42 
42 8 7 6 5 4 3 2 1 0

For this Discussion, consider yourself in the following scenario: As an instructional designer, you have noticed an increased attrition rate in a particular online course. The facilitators of the course have reported back to you that students have demonstrated a lack of motivation to participate in and complete the course. Based on Learning Resources, first identify what factors are most likely to motivate someone in an online classroom (these factors could be intrinsic or extrinsic). Next, create a plan to boost the motivational level of these online learners utilizing Keller’s ARCS model and/or one of the other motivation theories you learned about this week. Be specific in your methodology for how you are going to increase motivation and be certain to link your methodology to the various components of the motivation theory upon which your plan is built.

Post a summary of motivational factors in an online classroom and, as well, summarize a plan to heighten motivation of online learners using Keller’s ARCS model.
