What is a Variable Expense?‌

Business expenses can be classified as either fixed (invariable) or variable. A fixed expense does not change based on a business’s other activities. Costs like rent and administrative salaries are fixed costs, which remain the same no matter how much a business is producing. Imagine a factory that produces pencils — the cost of renting the factory building will remain the same, month after month, no matter how many pencils the company actually produces.

Variable expense ratio expresses variable expenses as a proportion of a company's sales. To calculate the variable expense ratio, simply divide the company's total variable expenses by the company's total net sales. To express the result as a percentage, simply multiply it by 100.

Therefore, A Task can be created in Outlook 2016 by clicking on the Tasks navigation item, or by clicking on the View tab. Thus, option A is correct.

Recently, Walmart offered a wireless data contract based on bandwidth used, with a minimum monthly charge of $42 for up to 5 gigabytes (GB) of use. Additional GB can be purchased at the following rates: $12 for an additional 1 GB, $28 for an additional 3 GB, and $44 for a capacity of 10 GB. What is the cost for a user who is expecting to use 9 GB

Answers

Answer:

For 9GB of data the user would pay $82 monthly!

Explanation:

To start off, our end goal is 9GB. We have the equation 9 = ? We can add up to our solutions with 1GB, 3GB, and 10GB. We can immediately rule out 10GB, since 9GB ≠ 10GB. To cost the least amount of money we can add up             3GB and 1GB = 4GB + 5GB = 9GB!

So, our equation is 3GB + 1GB + 5GB = 9GB, now lets figure out the cost!

                                $28 + $12 + $42 = $82

For 9GB of data the user would pay $82 monthly!

we need to send 254 kbps over a noiseless channel with a bandwidth of 15 khz. how many signal levels do we need

Answers

Answer:

The level of the signal is 353.85

Explanation:

Data rate determines the speed of the data transmission.

The data rate depends on the following factors

The available bandwidthnumbers of signal levelsthe quality of the channel ( Means the level of noise )

The data is transmitted either from a noiseless channel or a noisy channel.

The given quality of the channel in the question is noiseless.

Use the following formula to calculate the signal levels

Bit rate = 2 x bandwidth x [tex]Log_{2}[/tex] ( signal level )

where

Transmitted Data = 254 kbps = 254,000 bps

Bandwidth = 15 khz = 15,000 hz

Placing values in the formula

254,000 = 2 x 15,000 x [tex]Log_{2}[/tex] ( L )

254,000 = 30,000 x [tex]Log_{2}[/tex] ( L )

254,000 / 30,000 = [tex]Log_{2}[/tex] ( L )

8.467 = [tex]Log_{2}[/tex] ( L )

L = [tex]2^{8.467}[/tex]

L = 353.85 levels

. Else-if is good selection statement that help us to solve problems in C++,mostly times same problem of same nature can also be solved via switch statement. Which one you prefer to use and why?

Answers

Answer:

Else-If statements

Explanation:

Personally, I prefer using Else-If statements for conditional statements since you can start with and If statement and add to it if necessary. Aside from this, Else-If statements also allow you to add more than one condition to be met by using tags such as and or and not. Switch statements are better in scenarios where you have a set of possible inputs or results and need a specific event to happen for each input/result, but this is not as common of a scenario so Else-If is usually my go-to conditional statement.

Which example can be used to perform a binary search?

Answers

Answer:

In any case, binary search can be used to solve more extensive scope of problem, for example, finding the next smallest or next-biggest element in an array comparative with the target regardless of whether it is present or missing in the array.

Explanation:

In computer science, binary search, otherwise called logarithmic search, is a search calculation that finds the position of an objective incentive inside an arranged array. Binary search compares  the  target value to the center component of the array. In the event that they are not equivalent, the half in which the value can't lie is dispensed with and the search proceeds on the other half, again taking the center value to contrast with the target value, and continues this until the target value is found. On the off chance that the search ends with the other half being empty, the target value isn't in the array.

Binary search is quicker than linear search aside from small arrays. Nonetheless, the array should be arranged first to have the option to apply  binary search. There are particular data structures intended for quick looking, for example, hash tables, that can be looked through more effectively than binary search.
