If the worksheet is opened by the user and he is in the cell B3, then the B3 and B6 are selected, If the user clicks the B6 after pressing the ctrl and the shift key.The shift and ctrl are used to select any two cells in the MS-Excel worksheet.The above question asked about which cell is selected when the user in on cell B3 and press the B6 while holding the ctrl and shift key. So the answer is "B3 and B6".Use two variables k and total to write a for loop to compute the sum of the squares of the first 50 counting numbers, and store this value in total. Thus, your code should put 1*1 + 2*2 + 3*3 +... + 49*49 + 50*50 into total. Use no variables other than k and total.
Answer:
Following are the statement in the C++ Language
int total=0; // variable declaration
int k;// variable declaration
for(k=0;k<50;k++) // iterating the for loop
{
total=total+k*k;// perform operation and calculating square of 50 number
}
Explanation:
Following is the description of the statement
Declared a variable "total" and "k" of the "int" type initialized the total variable with the value 0. Iterating the for loop for calculating the squares of the first 50 counting numbers. So we will execute the loop less then 50 . In this loop, we counted the square of 50 number in the "total" variable.Care should be taken whenever you post comments or photos to any social media or other websites, because each of these online activities either add to or detract from your personal brand.1.

Which of the following is not a component of the programming phase of facility construction? deciding what to build examining space, cost, and other criteria designing the facility with architects deciding what events will be held at the facility and addressing capacity and amenities issues deciding the number and location of food and beverage preparation and sales areas
The programming phase focuses on fundamental design and planning aspects of facility construction but does not typically include deciding which events will be held at the facility. It lays out foundational design elements like capacity and amenities, while event scheduling pertains to operational planning.
The component that is not a part of the programming phase in facility construction is 'deciding what events will be held at the facility'. Programming, as a part of the design process, focuses on gathering information about the project, such as site inventory, analysis, and understanding user needs, environmental conditions, and economic considerations. This phase includes activities like deciding what to build, examining space, cost and other criteria, and integrating findings into the design with architects. It specifically deals with the fundamental aspects of designing the facility, ensuring the design maintains a focus on elements like capacity and amenities to meet users' needs. However, decisions related to events pertain to operational planning, which is distinct from the initial construction programming.
Programming provides the critical foundation for later stages such as schematic design, design development, construction documentation, and construction administration. This early stage of planning helps lay out the essential frameworks and supports potential adaptability in design—not detailed operational planning such as event scheduling.
Give a recursive implementation for the function: def is_sorted(lst, low, high) This function is given a list of numbers, lst, as well as two indices: low and high (low ≤ high), which indicate the range of the indices for the elements that should to be considered. When called, the function should determine if the elements that are placed at the low, low+1, …, high positions, are in an (ascending) sorted order. That is, it should return True if-and-only-if lst[low] ≤ lst[low+1] ≤ … ≤ lst[high] For example, if lst = [1, 3, 6, 8, 12, 15, 31], the call is_sorted(lst, 0, 6), will return True. Implementation requirements: Your function should run in worst case linear time. That is, if n is the size of the range low, low+1, …, high, calling is_sorted(lst, low, high) will run in �(�). Note: Write your implementation.
Answer:
# recursive method to find if list is in ascending order
def is_sorted(list, low, high):
if low >= high: # if reached end of list
return True
if list[low] > list[low+1]: # if item at low is greater than low+1
return False # return false
return True and is_sorted(list, low+1, high) # or return True and recursion call to low+1

Who would be a tippee for purposes of insider trading? a. a janitor who gathers information by reading files on corporate counsel's desk b. an MBA student who tracks the market very closely c. a broker who once worked in the pharmaceutical industry d. All of the above would be tippees.
Answer:
Option A is correct.
Explanation:
A janitor that collects data through reviewing reports on a business counsel's desk could be a tippee for insider trading activities.
Probably, the justification for insider trading remains wrong being that it offers each insider the undue benefit on and around the marketplace, gets the insider's preferences beyond them for which they assume the trustee responsibility, as well as enables the insider to unfairly manipulate the cost of the inventory of a business.
So, the following are the reason the other options are not correct according to the given scenario.

The use of simulations has been limited by their ____ a. inability to incorporate situations that a trainee might encounter b. inability to be used on a desktop computer c. need for employees to travel to a central training location d. high development costs
Answer: d
High development costs.
Explanation: Simulation is an approximate imitation of a process or a system that represents it overtime.
In Computer simulation is said to be a process of mathematical modelling that is performed on a computer and is designed to predict the behaviour of or the outcome of a physical system. Computer simulations are now useful tools for the mathematical modeling of many natural systems like in computational physics, astrophysics, climatology, chemistry, biology and manufacturing and also human systems like in economics, psychology, social science, health care and engineering.
" Simulations can be used to explore and gain new insights into new technology and to estimate the performance of systems too complex for analytical solutions and also to do a wide range of other things", but its development cost is very high, Very expensive.
Answer:
D. High development costs
Explanation:
Simulations try to as much as possible imitate the functions or activities of a system or process. They cut across various disciplines such as education, technology, science, management and so on.
One common ground about simulations is that it accrues high development costs. This is due to its closeness to the real-world application. Each block of the real process has to be appropriately simulated to ensure that the same results are obtained.

When evaluating portable CD players, you consider price, the sound quality, and ease of using the controls. These are your ______ in the purchased decision process.
Answer:
Hi you haven't provided the options to the question so I will just give the answer in my own words and you can check with the options.
Answer is ALTERNATIVES
When evaluating portable CD players, you consider price, the sound quality, and ease of using the controls. These are your ALTERNATIVES in the purchased decision process
Explanation:
Purchase decision process is the decision making process used by consumers regarding the market transactions before, during and after the purchase of a good or service.
There are five stages involved in purchase decision process which are: need recognition,
Information search, evaluation of alternatives, purchase decision and post purchase behavior.
Evaluation of alternatives: The information search reveals different products for the consumer to evaluate and understand which product would be appropriate, this can also be referred to as the consumer's alternatives.
Therefore, the answer that best suits the question is ALTERNATIVES. When evaluating portable CD players, you consider price, the sound quality, and ease of using the controls. These are your ALTERNATIVES in the purchased decision process
Answer:
They are my "Alternatives" in the purchase decision process
Explanation:
Before customers take the bold step of purchasing goods or paying for services, they usually pass through five stages. These five stages are:
1. The problem recognition stage.
2. The information search stage.
3. Evaluation of alternatives stage.
4. Purchase decision stage.
5. Post- purchase evaluation stage.
This then implies that before a product is finally purchased or before a service is paid for, the process of buying that product/service commences long before the actual acquisition of the service/product.
In the first stage, the consumer understands/recognizes that there is a problem or need that could be met by a product.
In the second stage, after recognition of the need that must be met by a product or service, the consumer then makes moves to search for further information regarding the possible products that could meet this need.
After the consumer has satisfactorily gathered enough information regarding the products that can possibly meet those needs, he/she then starts evaluating those products/service with regards to the belief in the company producing the products, the degree of importance, characteristics and abilities of the commodity, satisfaction, price etc, in order to choose wisely and correctly.
Therefore, if I consider price, sound quality etc when evaluating portable CD player, those things I consider are my alternatives in the purchase decision process.
