1.) How many grams of B are there in a sample of B that contains 6.55×1023 atoms?

2.) A 19.35 gram sample of chromium is heated in the presence of excess fluorine. A metal fluoride is formed with a mass of 33.49 g. Determine the empirical formula of the metal fluoride. (Enter the elements in the order Cr , F)

3.) A 25.34 gram sample of chromium is heated in the presence of excess iodine. A metal iodide is formed with a mass of 210.9 g. Determine the empirical formula of the metal iodide. (Enter the elements in the order Cr , I)

A certain data distribution has a mean of 18 and a standard deviation of 3

Wha, is the value would have a Z-score of -3.2?

Assuming that the distribution is normal, use the Empirical Rule to determine what proportion of this distribution would be found to be between 15 and 24

Assuming that the distribution is normal, use the Empirical Rule to determine what proportion of his distribution would be found to be between 12 and 15

Now imagine that this distribution is NOT guaranteed to be normally distributed. What would be the minimum proportion of this distribution that might be found between 13.5 and 22.5?

PLEASE NO USE OF LINKED LIST OR ARRAYS(USE CHARACTER POINTERS INSTEAD) TO HOLD DATA STRUCTURES

This lab, for which you may work in groups of two, will require you to use a C structure to hold a record of any kind of data, i.e., address book, library of books as with chapter 14, etc. These records will be held in dynamic memory using memory allocation (malloc) to create new memory and the function (free) to release memory created via (malloc). Do not use linked lists for this assignment, we are using dynamic memory allocation to hold records, not using linked lists. The structures will act as an in memory database for your records (structures), and you will need to create enough memory to hold all of your records, but also when you remove records, you will need to allocate new memory, move the data over to that memory space, and free the old memory (instead of using a static size array). No use of arrays is allowed to hold your structures, but you can use arrays in other places in your program. Your program will prompt for information that will be added to a new structure that will be added when you call the add function. Delete is as simple as just taking the last record out of your database (i.e. no need to search for a “record” to delete - this assignment is about pointers and memory allocation / free, so no need to make the algorithm more complicated). In addition to your memory to hold your data / structures, your program will also need to hold a static duration memory type that will serve as the counter for how many times the database has changed. Along with the amount of times the database has changed, you will also need to have a variable to hold the number of records in your database, functions to calculate size (records multiplied by sizeof struct), and functions to add, print, and delete records. You will not be required to use lookup functions, print is just the entire database. To manage your in-memory database, you will need to use some pointers to hold locations of your data. Please take some time to write down examples of where you will need to have pointers. You will need to have at least a pointer to the beginning of your database memory, another to show which record you are on, but think about the need for other pointers when you think about functions that will delete a record, add a record, etc. One of the major points of this assignment is not just the ability to manage records in memory, it is also about how to manage the memory itself. There is a huge inherent danger in how memory is allocated and subsequently not released properly which will create a “memory leak” in your program which will consume memory over time and crash your system (due to all the memory being used, or your process hitting a max limit of memory). This will mean that you will need to manage how pointers are pointing at data very carefully as it is very easy to create a memory leak and your program will not crash, it will just not release memory properly. You will need a menu to prompt users for the above requirements that may look like: MENU ======= 1. Print all records 2. Print number of records 3. Print size of database 4. Add record 5. Delete record 6. Print number of accesses to database 7. Exit Once you have gathered the appropriate information you will need to manipulate the data to hold the data correctly, but we are not using File I/O to maintain state on the data (would require too much time). Your database is a memory only database, so once your program ends, your database is gone. Being this is the case, it will be important to create a header file that has some data in it (5-7 records), so you will not need to enter all the records every time.

In 2016, Gandoff sold inventory to Bilbo Co for $600,000 on credit. This merchandise had cost Gandoff $300,000. At the end of 2016 Bilbo had not sold any of this merchandise nor had they paid Gandoff for the merchandise

In 2017 Bilbo paid off Gandoff and had sold 70% of the merchandise acquired from Gandoff.

In 2018 Bilbo sold the rest of the merchandise it had acquired from Gandoff

REQUIRED:

A) MAKE THE JOURNAL ENTRY GANDOFF MAKES WHEN IT SELLS THE MERCHANDISE TO BILBO (GANDOFF USES THE PERPETUAL METHOD FOR INVENTORY)

C) MAKE ANY NECESSARY WORKSHEET ENTRIES FOR 2016 CONNECTED WITH THIS MERCHANDISE

D)MAKE ANY NECESSARY WORKSHEET ENTRIES IN 2017 CONNECTED WITH THIS MERCHANDISE

E) MAKE ANY NECESSARY WORKSHEET ENTRIES IN 2018 CONNECTED WITH THIS MERCHANDISE

F) IN 2016, GANDOFF REPORTED UNCONSOLIDATED INCOME OF $4,000,000 AND BILBO REPORTED INCOME OF $300,000 WHAT WAS CONSOLIDATED INCOME IN 2016

G) IN 2017, GANDOFF REPORTED UNCONSOLIDATED INCOME OF $4,300,000 AND BILBO REPORTED INCOME OF $333,000 WHAT WAS CONSOLDIATED INCOME IN 2017

H) IN 2018 GANDOFF REPORTED UNCONSOLIDTED INCOME OF $5,000,000 AND BILBO REPORTED INCOME OF $500,000 WHAT WAS CONSOLIDATED INCOME IN 2018?

Colonial Adventure Tours Case

• The owner of Colonial Adventure Tours knows that being able to run queries is one of the most important benefits of using a DBMS. In the following exercises, you will use the data in the Colonial Adventure Tours database shown in Figures 1-15 through 1-19 in Chapter 1. (If you use a computer to complete these exercises, use a copy of the Colonial Adventure Tours database so you will still have the original data when you complete Chapter 3 exercises.) In each step, use QBE to obtain the desired results. You can use the query feature in a DBMS to complete the exercises using a computer, or you can simply write a description of how you would complete the task. Check with your instructor if you are uncertain about which approach to take.
• Save the file on your computer with your last name in the file name. (Example: case_1-1 _Jones.doc)
• Click the Choose File button to find and select your saved document.

18. One of the reservations agents at Colonial Adventure Tours created the query shown in Figure 2-49 to list each trip name and the last name and first name of each corresponding guide. The query results included 410 records, and he knows that this result is incorrect. Why did he get so many records? What should he change in the query design to get the correct query results?
