Using cell references enter a formula in B6 to calculate monthly payments for the loan described in this worksheet Omit the optional arguement use a negative value for pv
Answers
Answer:
= PMT(B4/B2, B2 * B3, B1)
Explanation:
The syntax to use is:
= PMT(Rate,NPER, PV)
To answer this question, the following assumptions will be made.
B1 = Present Value i.e. PV
B2 = Number of Payment Period i.e n
B3 = Duration (in years)
B4 = Rate
So, the formula to enter in B6 is:
= PMT(B4/B2, B2 * B3, B1)
The above formula will return the monthly payment in cell B6
Design a TestScores class that has fields to hold three test scores. The class should have a constructor, accessor and mutator methods for the test score fields, and a method that returns the average of the test scores. Demonstrate the class by writing a separate program that creates an instance of the class. The program should ask the user to enter three test scores, which are stored in the TestScores object. Then the program should display the average of the scores, as reported by the TestScores object.

Answer: 32cm
Explanation:
Since the focal length of the convex lens is 8cm, the distance between the object and its image be 4f which will be:
= 4 × f
= 4 × focal length
= 4 × 8
= 32cm
The distance between the object and its image is 32cm.

A video streaming website uses 32-bit integers to count the number of times each video is played. in anticipation of some videos being played more times than can be represented with 32 bits, the website is planning to change to 64-bit integers for the counter. which of the following best describes the result of using 64-bit integers instead of 32-bit integers? a. 2 times as many values can be represented. 32 times as many values can be represented. 2^32 times as many values can be represented. 32^2 times as many values can be represented. I know the answer is 2^32 but can someone explain it to me?
Answers
Answer:
2³² times as many values that can be represented
Explanation:
A 64 bit register can hold 2⁶⁴ different values, while a 32 bit register can hold 2³² different addresses
Therefore, a 64 bit can represent 2⁶⁴ ÷ 2³² = 2³² times as many values as can be represented by 32-bit
Therefore, the 64 bit can represent 2³² times as many values that can be represented by a 32 bit integer

Katie wants to use VLOOKUP for a column in a table. Which value of the mode parameter should she use to look for an exact match of the searched data?
Katie should use the __ value of mode parameter for an exact match with the searched data.
Answers
Answer:
The exact match mode is the mode parameter that Katie should use to look for an exact match of the searched data
Further Explanation:
The VLOOKUP function in Excel helps us search for and retrieve information from a particular column in a table and lookups a value in the left-most column of the table. It has two modes of matching.
Exact matching – When you perform a range_lookup, an argument FALSE is defined to mean that there is an exact match of the return value.
To achieve this, select a cell in your Excel worksheet
Type =VLOOKUP in the type bar of the Excel sheet
Select the value to look up and then select the data range
Type the column number that you want to search and then type FALSE

Activity in September 2014, the Federal Bureau of Investigation (FBI) announced that is next generation Idenufication system was fully functional The FBI named it the integrated Automated Fingerprint Identification system (IAFIS), Conduct online research on this system and answer the following questions 1. Which elements can be stored in IAFIS? 2. What is the response time of this system? 1. How has this system benefited the FBI
Answers
Answer:
(Answers may vary.)
In addition to fingerprints, IAFIS stores criminal histories, mug shots, and physical information like scars, tattoos, eye color, hair color, weight, and height. It also stores fingerprints of individuals who are or were employed by the US military and the federal government.
The system’s average response time for criminal fingerprint processing is about 27 minutes. Civil fingerprint processing takes over an hour.
Previously, the tenprint submission and identification was a manual, tedious process. It took the FBI weeks or months to process a single fingerprint submission. IAFIS has automated this process and added advanced identification capabilities. The submission and processing takes just few minutes. This has helped the FBI solve and prevent crime and tighten holds on criminals and terrorists.
