What is the inter-quartile range of the given data set?
a.2
b.3
c.6
Answers
20 - 17
3
Hope this helps!
----------------------------
----------------------------
Explanation:
The left edge of the box is at 17. This is the first quartile, so Q1 = 17
The right edge of the box is at 20. This is Q3 = 20 (third quartile)
Subtract the quartile values to get the inter-quartile range (IQR)
IQR = Q3 - Q1
IQR = 20 - 17
IQR = 3

describe a situation in which 2 angles are both congruent and complementary
Answers
The only situation in which two angles are both congruent and complementary is when their measures are both 45°:
Two angles are complementary if their sum is 90°, and they are congruent if their measures are the same, say n. Therefore, to find two congruent angles which are complementary, we solve the following equation:
n+n=2n
2n = 90
2n/2 = 90/2
n=45
Two angles that are both congruent and complementary can be found in right angles.
Two angles that are both congruent and complementary can be found in the case of right angles. When two angles are right angles, they are both congruent (having the same measure) and complementary (adding up to 90 degrees).

A student got a grade of 85% on a text in which she answered 3 questions incorrectly. How many questions were on the test?
Answers
To find this, we must first find out how much was taken off of 100% to get 85%. In terms of math, this can be put like this:
100% - X = 85%
Now, we solve for X.
100% - X = 85%
Add X to both sides.
100% = 85% + X
Subtract 85% from both sides.
100% - 85% = X
Subtract.
15% = X
This means that 15% was taken off of 100% to get 85%. In other words, 3 incorrect questions are equal to 15% of the final grade. In terms of math, we can put it like this:
3 = 15%
Now, let's go back to the first question we asked at the beginning.
"How much of 100% is one question worth?"
To find this, we need to make 3 become 1 in the equation 3 = 15%.
3 = 15%
Divide both sides by three.
3/3 = 15%/3
Divide.
1 = 5%
This means that 1 question is worth 5% of the grade. With this information, we can find out how many questions it takes to get 100% of the grade. To do this, we need to make the 5% become 100%.
1 = 5%
Multiply both sides by 20.
20(1) = 20(5%)
20 = 100%
This means that there are a total of 20 questions on the test.
By interpreting the student's grade of 85% and knowing that 3 questions were answered incorrectly, we can infer that the test consisted of 20 questions in total.
To calculate how many questions were on the test, we first need to establish the relationship between the number of questions answered incorrectly and the student's overall percentage score. If the student got an 85% on the test, this means they answered 85% of the questions correctly. With 3 questions answered incorrectly, we can assume that these incorrect answers account for the remaining 15%. To find the total number of questions on the test (let's denote it as x), we set up a simple equation:
0.15x = 3
Solving for x yields:
x = 3 / 0.15
x = 20
Therefore, the test consisted of 20 questions in total.

Michael has a total of$4.40 in dimes (1 dime=$0.10) and quarters (1quarter=$0.25), and he has 20 coins in total. Which of the following systems of equations can be used to find the number of dimes, d, and the number of quarter,q, he has?
Answers
0.1d+0.25q=4.40 Let's just read what this says: first, # of dimes (d) plus # of quarters (q) is 20.The second equation can be called the VALUE EQUATION; it says that one tenth of a dollar ($0.10) times the # of dimes is part of the total monetary value, and that one quarter of a dollar ($0.25) times the # of 'quarter' coins is the other part of this stash, and it totals $4.40. VOTE FOR A.
Final answer:
To solve for the number of dimes and quarters Michael has, we use two equations: 0.10d + 0.25q = 4.40 for the total value, and d + q = 20 for the total quantity of coins.
Explanation:
To find the number of dimes, d, and the number of quarters, q, Michael has, we need two equations to form a system. The first equation will represent the total amount of money in terms of dimes and quarters, and the second one will represent the total number of coins.
The value of a dime is $0.10 and the value of a quarter is $0.25. The total amount of money, $4.40, can be represented as 0.10d + 0.25q = 4.40. This is the value equation.
Since there are 20 coins in total, the second equation will simply be the count of both types of coins together: d + q = 20. This is the quantity equation.
The system of equations to find the number of dimes and quarters is:
0.10d + 0.25q = 4.40 (value equation)
d + q = 20 (quantity equation)
Sara was on a cliff 25 feet above sea level. she jumped into the sea and descended a total of 37 feet. how many feet below sea level did she travel? justify your reasoning
Answers
Sara travels a distance of 12 feet below sea level when she jumped into the sea.
What is the Subtraction operation?Subtraction is a mathematical operation that deducts the right-hand operand from the left-hand operand.
for example 4 -2 = 2
We have been given that Sara was on a cliff 25 feet above sea level. she jumped into the sea and descended a total of 37 feet.
To determine the number of feet below sea level travel by Sara
The number of feet below sea level = total descended - cliff of a number of feet above sea level.
Here total descent is 37 feet and the cliff is 25 feet above sea level.
Substitute the value in the above equation,
The number of feet below sea level = 37 - 25
The number of feet below sea level = 12 feet
Therefore, she travels a distance of 12 feet below sea level.

Answers
The question is missing critical information as it lacks the proportion or number related to the shaded part of the model. Without this detail or a visual representation, it's not possible to determine the accuracy of Gary or John's statements.
Explanation:The question provided seems to be missing critical information, specifically the proportion or number that Gary and John are referring to when they mention how much of a model is shaded. In a typical mathematics problem regarding fractions or percentages, students would be asked to determine if statements about the shaded portion of a model are correct. Without the visual model or additional context indicating the proportion of the model that is shaded, it's impossible to conclude which student, Gary or John, is correct.
In order to answer correctly, we would need either a clear description of the model and its shaded parts or, preferably, a visual representation. Then, we would analyze the shaded portion to assess which statement about the fraction or percentage shaded is accurate. If we had this information, we could illustrate the process of comparing the given fraction or percentage with the actual shaded section of the model.
Unfortunately, without the necessary details, we can neither confirm if Gary, John, or both are correct, nor can we properly address the question.

Why is indirect compensation important to recruiting and retaining employees?
Answers
Indirect compensation is significant for retaining employees as it creates job security, motivates productivity, and reduces costs of recruitment and training. It also plays a role in managing modern workforce, which requires a more flexible and multi-faceted approach to retain.
Explanation:Indirect compensation is important for recruiting and retaining employees in several ways. One of them is that it often works under an implicit contract, where the employer tries to maintain wages even when the economy or the business is not doing well, providing a form of protection for the employees. This implicit contract can make workers feel secure and motivated, hence improving productivity and reducing the likelihood of them leaving the firm.
Moreover, retaining employees from more modern generations can be more challenging since their expectations differ from those of previous generations; they tend to lack inherent company loyalty, hence, frequent rewards, praises, and feedback are essential. On the other hand, the efficiency wage theory argues that better pay results in higher productivity since the employees are motivated to work harder to maintain their current job because they realize that they could suffer a wage cut if they were to lose it.
Lastly, to avoid the costly and time-consuming endeavor of hiring and training new employees, employers often find it advantageous to pay a little more to the existing ones, a strategy that not only minimizes costs but also retains skilled and motivated employees.

An investment earns 6% simple interest. What amount of principal is needed to have $3000 after 5 years? Round your answer to the nearest cent.
Answers
The principal amount needed to have $3000 after 5 years with 6% simple interest is $10,000.
To find the principal amount needed to have $3000 after 5 years with 6% simple interest, we can use the formula for simple interest:
Simple Interest = Principal * Rate * Time
where Rate is the interest rate as a decimal, and Time is the time period in years.
We can rearrange this formula to solve for the Principal:
Principal = Simple Interest / (Rate * Time)
In this case, we want to find the Principal that will yield $3000 after 5 years with 6% simple interest. Therefore, we have:
Simple Interest = $3000
Rate = 0.06
Time = 5 years
Plugging these values into the formula, we get:
Principal = $3000 / (0.06 * 5) = $10,000
Therefore, the principal amount needed to have $3000 after 5 years with 6% simple interest is $10,000.
