The concept that can be used in order to answer this item is that of man-days. The total number of man-days required to do the job should always be constant.

This can be illustrated by the givens above.
Scenario 1:
N1 = (4 employees)(4 days) = 16 man-days

Scenario 2:
N2 = (2 employees)(8 days) = 16 man-days

The equation for determining the value of e is equal to,
k = (d)(e)

The answer is the second choice.

Answer: inverse variation; $de = k$

Step-by-step explanation:

Given: In a company, it takes 4 employees 4 days to complete a task.

Work done by complete the task by = $4\times4=16$

Similarly, It would take 2 employees 8 days to complete the same task.

Work done by complete the task = $2\times8=16$

There is inverse variation which means if number of workers decreases then the number of days increases.

If e represents the number of employees working on the task and d represents the number of days it takes them to complete that task.

Then, by inverse variation $de = k$

[PLEASE ANSWER BOTH QUESTIONS] The following data points represent the number of quesadillas each person at Toby's Tacos ate. So

Fynjy0 [20]

Answer:

Part 1: Already solved.

Part 2: 1 quesadilla.

Step-by-step explanation:

Part 1: The data points given are 0, 0, 1/4, 1/2, 1/2, 1, 1, 1, 5/4, 2, and 2.

The data are already sorted from least to greatest.

Part 2: To get the interquartile range, we must know the first and third quartiles. To find those, we need to know the median of the data.

There are 11 data points, so we can cross out 5 numbers on the left and cross out 5 numbers on the right. That leaves a median of 1.

Since we know the median is 1, we can find the first quartile by finding the median of the following numbers: 0, 0, 1/4, 1/2, 1/2 (any number less than 1). There are five numbers, so cross out two numbers from the left and cross out two numbers from the right. We are left with a first quartile of 1/4.

Now that we have the first quartile, we need to find the third quartile. Since the median was actually the first "1" in the data set, the third quartile will be the median of the numbers to the right of that "1": 1, 1, 5/4, 2, 2. Cross out the leftmost two numbers, and cross out the rightmost two numbers. We are left with a third quartile of 5/4.

Now that we have both the third and first quartiles, we can find the interquartile range! The IQR is calculated by finding the third quartile minus the first quartile. 5/4 - 1/4 = 4/4 = 1.

So, your interquartile range is 1 quesadilla.

Hope this helps!

Please choose the answer that describes the scientific notation for 5,098,000.

avanturin [10]

Scientific notation is the representation of a number in a power of ten, with a sequence of digits placing the comma after the first digit, and the power or then that is mathematically consistent with the number. For example 400 is 4.00 * 10^2; 3100 is 3.100 * 10^4; 13421 = 1.3421 * 10 ^4. It is important that you have only one digit before the comma. So, 5,098,00 is 5.098 * 1,000,00 = 5.098 * 10^6. <span>The answer is the option c. 5.098 * 10^6.</span>

malik collects rare stamps and has a total of 212 stamps. he has 34 more domestic stamps than foreign stamps. let x represent th

valina [46]

<span>x = number of domestic stamps

y = number of foreign stamps

Malik collects rare stamps and has a total of 212 stamps.

=> x + y = 212

he has 34 more domestic stamps than foreign stamps.

=> x = y + 34

which equation represents the total number of stamps malik collected?

x + y = 212

which equation represents the difference in the number of foreign and domestic stamps malik collected?

x - y = 34

which system of linear equations represents the situation?

x + y = 212
x - y = 34
