Answer:
A unit rate always relates quantites with the same unit
Step-by-step explanation:
I could be wrong but I think this would the answer for this.
Answer:
The answer is 4) A unit rate always relates quantities with the same units.
Step-by-step explanation:
It cannot be 1 because a unit rate relates a quantity to 1. Hence the word unit which means single or undivided whole.
It cannot be 2 because you can indeed use unit rates to compare two rates. In fact we do all the time in math! Just like comparing fractions.
It cannot be 3 because the rate has to be equivalent to its unit rate or else its wrong.
Thus making it four!

is y=10x a function?
Answer:
Yes
Step-by-step explanation:
A scale drawing of a rectangular room has a length of six inches and a width of 4 inches. The drawing uses a scale of one inch to three feet. Find the cost to carpet the room if carpeting costs $5.50 per square foot. What is the shape of the room? Answer the next questions about the above room. So what is the square footage
Answer:
We know that:
1 inch in the drawing, equals 3 feet in the real room.
Then if the scale is 6 in by 4 in, the actual room is:
6*3ft by 4*3ft
18ft by 12ft.
The total area of the room is:
18ft*12ft = 216ft^2.
Now we know that the price of the carpet is $5,50 per square ft,
The area of the room is 216 ft^2, then if we want to carpet the whole room, we need to pay 216 times $5.50.
Cost = 216*$5.50 = $1,188

At Sparrowtown Consulting, the head of human resources examined how the number of employees with health care benefits varied in response to policy changes.
According to the Graph provided, what was the rate of change between 2012 and 2014?
Step-by-step explanation:
Rate of change = final - initial / time(in years)
= 41 - 43 / 2014 - 2012
= - 2 / 2
Rate of change = - 1
Therefore, the number of employees with health care benefits reduced by 1 person per year between 2012 - 2014 in response to policy changes.

Answer:
C. 16
Step-by-step explanation:
First of all, these two angles are corresponding angles, which means that they equal each other. So, the equation here would be: 2x+18= 4x-14.
Step 1- Move the variables to one side.
2x+18= 4x-14
-2x -2x
18= 2x-14
Step 2- Add 14 to both sides of the equation.
18= 2x-14
+14 +14
32= 2x
Step 3- Divide 2 to both sides of the equation to isolate the variable.
32= 2x

The sum of the first n odd numbers is equal to the nth square. 1+3+5+7+...+ (2n-1) = n² To prove this by mathematical induction, what will be the induction assumption? A. The statement is true for n=k: 1 + 3 +5+7+...+(2k-1) = k² B. The statement is true for n = 1: 2x1 - 1 = 1² C. The statement is true for n=k+1:1+3+5+7+...+(2k-1)+(2k + 1) = (k+ 1)² D. The statement is true for n=k+ 1: 1+3+5+7+...+(2k-1)+(2k + 2) = (k+ 2)² Prove that 7"-4" is divisible by 3 Q4. On a factory feedback form, employees were asked to rate the work atmosphere at the factory using a score from 1 to 5, where 1 was poor and 5 was very good. distrubtion of X. Score, X Frequency 1 3 2 4 3 10 4 23 5 10 i. Use the frequency distribution shown to construct a probability distribution for the random variable X. Find the expected value of the distribution ii.
In question 1, the recursive formula for the balance of Mohamed's credit card debt each month can be written as Bₙ = 1.02Bₙ₋₁ - 300, where Bₙ represents the balance in the nth month.
In question 2, (i) The second term in the expansion of (y-2x)³ is option B: -8y³x.
(ii) Row 7 of Pascal's Triangle is option B: 1, 5, 10, 10, 5, 1.
(iii) Expanding (2x³ + 1)³ completely yields 8x⁹ + 12x⁶ + 6x³ + 1.
In question 3, To prove the statement that the sum of the first n odd numbers is equal to the nth square (1+3+5+7+...+(2n-1) = n²) by mathematical induction, the induction assumption is option A: The statement is true for n=k: 1 + 3 + 5 + 7 + ... + (2k-1) = k².
In question 4, the probability distribution for the random variable X, representing the work atmosphere scores, can be constructed using the given frequency distribution.
In question 1(i), the recursive formula Bₙ = 1.02Bₙ₋₁ - 300 represents the balance of Mohamed's credit card debt each month. The balance increases by 2% each month due to interest and decreases by the monthly payment of AED 300.
In question 1(ii), to find the first three iterates of the function f(x) = 5x + 4 starting with x₀ = 2, we substitute the value of x₀ into the function and then repeatedly apply the function to obtain x₁, x₂, and x₃.
In question 2, the answers are obtained as follows:
(i) To find the second term in the expansion of (y-2x)³, we use the binomial expansion formula (a-b)³ = a³ - 3a²b + 3ab² - b³. In this case, a = y and b = 2x. Using the formula, the second term is -3a²b = -3(y)²(2x) = -3y²(2x) = -6xy². However, in the given options, the term is in the form -8y³x. To match this form, we can rewrite -6xy² as -8y³x. Therefore, the second term is -8y³x, which corresponds to option B.
(ii) Pascal's Triangle is a triangular arrangement of numbers where each number is the sum of the two numbers above it. Row 7 of Pascal's Triangle is 1, 6, 15, 20, 15, 6, 1. However, none of the options matches this row. Thus, the given options are incorrect, and the correct row 7 of Pascal's Triangle is not provided.
(iii) To expand (2x³ + 1)³ completely, we use the binomial expansion formula (a + b)³ = a³ + 3a²b + 3ab² + b³. In this case, a = 2x³ and b = 1. Applying the formula, we obtain (2x³ + 1)³ = (2x³)³ + 3(2x³)²(1) + 3(2x³)(1)² + (1)³. Simplifying this expression gives 8x⁹ + 12x⁶ + 6x³ + 1.
Therefore, the second term in the expansion of (y-2x)³ is -8y³x, the correct row 7 of Pascal's Triangle is not provided, and the expansion of (2x³ + 1)³ is 8x⁹ + 12x⁶ + 6x³ + 1.
In question 3, To prove the given statement using mathematical induction, we need to follow the steps of induction: base case and induction step.
The base case is when n = 1. We need to show that the statement is true for n = 1. Evaluating the left-hand side (LHS) and right-hand side (RHS) of the equation, we have 1 = 1², which is true.
Next, we assume that the statement is true for some value k, which is the induction assumption. In this case, the assumption is that 1 + 3 + 5 + 7 + ... + (2k-1) = k².
Now, we need to prove that the statement holds for n = k+1. This is the induction step. We add (2k+1) to both sides of the assumption and evaluate the LHS and RHS. The LHS becomes 1 + 3 + 5 + 7 + ... + (2k-1) + (2k+1), and the RHS becomes (k+1)².
By applying the induction assumption and simplifying the LHS, we can show that it is equal to (k+1)², proving the statement for n = k+1.
Therefore, option A: The statement is true for n=k: 1 + 3 + 5 + 7 + ... + (2k-1) = k² is the correct induction assumption for proving the sum of the first n odd numbers is equal to the nth square.
Regarding the second part, to prove that 7ⁿ - 4ⁿ is divisible by 3, we can use mathematical induction. By verifying the base case (n = 1) and assuming the statement is true for n = k, we can prove that it holds for n = k+1.
In question 4, to construct the probability distribution for the random variable X, we use the frequency distribution to determine the probabilities associated with each score. The expected value of the distribution can be calculated by multiplying each score by its corresponding probability and summing the results.
By understanding the concepts and applying the appropriate formulas and techniques, the solutions to these questions can be obtained.

what is 31.05 dollars divided equaly into three people
Hey there!
Each person would mostly get approximately $10.35 because you simply DIVIDE 31.05 from 3 & 10.35 * 3 gives you $31.05
Here’s an equation you can set it up as
• 3p = number of people
• 31.05 could be the one the one we’re dividing with p
• So your equation will most likely look like:
3p = 31.05
“3p = 31.05”
• DIVIDE both of your sides by 3
3p/3 = 31.05/3
• Cancel out
3p/3 because that gives you 1
• Keep
31.05/ 3 because that helps us solve what we give to the number of people
p = 31.05 / 3
➡️ 31.05 / 3 = 10.35
Thus, each person will get: 10.35
So that further a do: your answer is “10.35”☑️

In a classroom with some girls and some boys, four students are chosen at random to lead a class discussion. All of those chosen are boys. The probability of this happening would be highly unlikely to occur by chance alone.
In probability theory, the probability of an event is a measure of the possibility of the event occurring. It is expressed as a value between zero and one, with zero representing impossibility and one representing certainty.
The formula for calculating the probability of an event is the number of ways the event can occur divided by the total number of possible outcomes. In this case, the probability of four boys being chosen from a mixed group of boys and girls is calculated as follows:
The probability of the first boy being chosen is the number of boys divided by the total number of students. If there are 30 students in the class, 15 boys, and 15 girls, then the probability of the first boy being chosen is 15/30.
The probability of the second boy being chosen is the number of remaining boys divided by the total number of remaining students. After the first boy is chosen, there are 14 boys and 29 students left. Therefore, the probability of the second boy being chosen is 14/29.
The probability of the third boy being chosen is the number of remaining boys divided by the total number of remaining students. After the second boy is chosen, there are 13 boys and 28 students left. Therefore, the probability of the third boy being chosen is 13/28.
The probability of the fourth boy being chosen is the number of remaining boys divided by the total number of remaining students.
After the third boy is chosen, there are 12 boys and 27 students left.
Therefore, the probability of the fourth boy being chosen is 12/27.To find the probability of all four boys being chosen, we multiply the probabilities of each event together:15/30 * 14/29 * 13/28 * 12/27 = 0.018 or 1.8%
Therefore, the probability of all four boys being chosen is only 1.8%. This means that it would be highly unlikely to occur by chance alone.

in facility location, as the number of retail stores increases, which is false?
a.
Customer service will improve.
b.
Fixed facility costs will increase.
c.
Transportation costs will increase.
d.
Inventory costs will increase.
The false statement among the options provided is: a. Customer service will improve.
While having more retail stores can potentially provide benefits such as increased accessibility and convenience for customers, it does not automatically guarantee an improvement in customer service. Customer service relies on several factors that are not solely determined by the number of retail stores:
Quality of Staff: The level of customer service primarily depends on the training, skills, and attitude of the staff members. It is essential to have well-trained and motivated employees who possess excellent communication and problem-solving abilities. The number of stores alone does not directly impact the quality of staff.
Training Programs: Retailers need to invest in comprehensive training programs to enhance their staff's customer service skills. This includes imparting knowledge about products, effective communication techniques, conflict resolution, and empathy, among other things. The presence of more stores does not guarantee a robust training program unless it is specifically implemented and maintained.
Management Practices: Effective management practices play a vital role in ensuring consistent and high-quality customer service across all stores. This involves setting clear service standards, providing ongoing support and guidance to the staff, monitoring performance, and addressing any issues promptly. The number of stores does not inherently improve management practices.
Organizational Culture: The overall culture within the retail organization greatly influences its customer service. If there is a customer-centric culture that values and prioritizes exceptional service, it is more likely to be reflected in all stores, regardless of their number. However, simply increasing the number of stores does not automatically create or enhance a positive organizational culture.
In conclusion, while having more retail stores may provide potential advantages in terms of accessibility and convenience, the improvement in customer service cannot be guaranteed without considering factors such as staff quality, training programs, management practices, and organizational culture. These elements have a more direct impact on customer service than the number of stores alone.

From the given diagram, the bearing of D from C is calculated by taking the angle measure of point D from North of C clockwise as follows;
D from C = 360⁰ - 45⁰ = 315⁰
Note; 45⁰ is the position of D from north of C anti clockwise, since we are interested in the clockwise measure of the bearing, we subtracted 45 degrees from 360 degrees; which is the sum of angle at a point.
