There are two main subtypes of quantitative data, which are discrete data and continuous data. Each subtype has different techniques for analysis.
1. Discrete data: This type of data represents whole numbers or counts that can only take specific values. Examples include the number of students in a class or the number of cars in a parking lot. Techniques used to analyze discrete data include:
a. Frequency distribution: A summary of the number of times each value appears in the dataset.
b. Measures of central tendency: Calculating the mean, median, and mode of the dataset to understand its central point.
c. Measures of dispersion: Assessing the range, variance, and standard deviation to understand the spread of the data.
2. Continuous data: This type of data represents measurements that can take any value within a range, such as height, weight, or temperature. Techniques used to analyze continuous data include:
a. Histogram: A graphical representation of the distribution of the data, using bars to represent the frequency of values within specific intervals.
b. Probability density function: A mathematical function that describes the probability of a continuous random variable falling within a specific range.
c. Regression analysis: A statistical method for analyzing the relationship between a dependent variable and one or more independent variables.
Both discrete and continuous data can also be analyzed using inferential statistics, such as hypothesis testing and confidence intervals, to make inferences about a population based on a sample of the data.

what kind of proof was used to find that m p is even? (you must provide an answer before moving to the next part.) multiple choice contraposition contradiction trivial direct
Our initial assumption that m is odd and p is even is false, and m + p must be even. Hence, it is proved that m + p is even.
Suppose that m is an odd integer and p is an even integer. Then, their sum m + p is odd. In this case, it is required to find what kind of proof is used to determine that m p is even.
The direct proof was used to find that m + p is even because it is a valid logical argument that establishes the truth of a proposition.
The method requires identifying the statements that are considered true (known as premises) and using them to establish the validity of the proposition being proven.
In this case, the proof uses the fact that m is odd and p is even to show that their sum is even.
Let's consider the definition of an even integer.
An integer is said to be even if it can be expressed in the form 2n, where n is an integer. Therefore, an even integer can be expressed as 2n and an odd integer can be expressed as 2n + 1.
The direct proof used to find that m + p is even is as follows: Suppose m is odd and p is even. Then, m can be expressed as m = 2k + 1 for some integer k, and p can be expressed as p = 2l for some integer l.
Therefore, their sum can be written as:m + p = (2k + 1) + 2l = 2k + 2l + 1 = 2(k + l) + 1
Since k and l are both integers, k + l is also an integer.
Thus, we can write the expression above as: m + p = 2(k + l) + 1
Since 2(k + l) is an even integer, and the sum of an even integer and an odd integer is always odd, we can conclude that m + p is odd. However, this contradicts the given statement that m + p is even.
Therefore, our initial assumption that m is odd and p is even is false, and m + p must be even.
Hence, it is proved that m + p is even.

David, Stephen and June share £96 in a ratio 2:3:3. How much money does each person get
Answer:
David gets £24, Stephen gets £36, and June gets £36.
Step-by-step explanation:
Firstly, add the ratio values together.
2:3:3 ⇒ 2 + 3 + 3 = 8
Next, divide £96 (your total) by 8.
£96 ÷ 8 = £12
Now, we have the number of pounds for 1 value.
Multiply 12 by each ratio value.
12 × 2 : 12 × 3 : 12 × 3
= 24:36:36
Therefore, David gets £24, Stephen gets £36, and June gets £36.
I hope this helped! I would really appreciate it if you would please mark me brainliest! Have a blessed day!
Answer:
David = £24
Stephen = £36
June = £36
Step-by-step explanation:
Total amount of money = £96
Ratio = 2:3:3
Total ratio = 2+3+3 = 8
David's share = 2÷8×96 = £24
Stephen's share = 3÷8×96 = £36
June's share = 3÷8×96 = £36
A tool box has the dimensions of 9 in by 6 in by 7 in. If Mark plans to double one dimension to build a larger tool box, he believes he would double the volume of the tool box. Is he correct?
Yes, Mark is correct he believes that doubling one of the dimensions would double the volume of his toolbox.
Volume refers to the space occupied by a 3-Dimensional space. The volume of a cuboid is given by:
V = l * b * h
where l is the length
b is the breadth
h is the height
V = 9 * 6 * 7

how would you decide if you needed a univariable (i.e., simple linear regression) or multivariable linear regression model?
The decision to use a univariable or multivariable regression model depends on the research question, data availability, model complexity, and goodness of fit.
What is the linear regression equation?
The formula for simple linear regression is Y = mX + b, where Y is the response (dependent) variable, X is the predictor (independent) variable, m is the estimated slope, and b is the estimated intercept.
When deciding whether to use a univariable or multivariable linear regression model, there are several factors to consider:
Research question: Consider the research question you are trying to answer. If you are interested in understanding the relationship between a single independent variable and a dependent variable, then a univariable regression model may be sufficient. However, if you want to explore the effect of multiple independent variables on a dependent variable, then a multivariable regression model may be more appropriate.
Data availability: Look at the data you have available. If you have only one independent variable that you believe is relevant to your research question, then a univariable regression model may be appropriate. However, if you have multiple independent variables that could potentially influence the dependent variable, then a multivariable regression model may be necessary.
Model complexity: Consider the complexity of the model you want to build. If you are interested in a simple linear relationship between an independent variable and a dependent variable, then a univariable regression model may be sufficient. However, if you believe that there are interactions between multiple independent variables that could affect the dependent variable, then a multivariable regression model may be necessary.
Model fit: Evaluate the goodness of fit of both univariable and multivariable models. Compare the R-squared values of each model to determine which model provides a better fit to the data. A higher R-squared value indicates a better fit between the independent and dependent variables.
Hence, the decision to use a univariable or multivariable regression model depends on the research question, data availability, model complexity, and goodness of fit.

Answer:
Length = 18 ft

Let the width of the rectangle be x ft
Therefore, length = (x + 14) ft
Area of rectangle = 72 sq ft
\( \therefore \: x(x + 14) = 72 \\ \therefore \: {x}^{2} + 14x - 72 = 0 \\\therefore \: {x}^{2} + 18x - 4x - 72 = 0 \\\therefore \: x(x + 18) - 4(x + 18) = 0 \\ \therefore \:(x + 18)(x - 4) = 0 \\ \therefore \:x + 18 = 0 \: \: or \: \: x - 4 = 0 \\ \therefore \:x = - 18 \: or \: \: x = 4 \\ \because \: dimensions \: of \: a \: rectangle \: \\ cn \: not \: be \: negative \\ \therefore \: x \neq \: - 18 \\ \implies \: x = 4 \\ \therefore \: x + 14 = 4 + 18 = 18 \\ length \: of \:the \: rectangle \: = 18 \: ft \\ width \: of \: the \: rectangle = 4 \: ft\)

The formula we need to use is given above. In this formula, we will substitute the desired values. Let's start.
\(P=3W+D\)A) First, we can start by analyzing the first premise. The team has \(8\) wins and \(5\) losses. It earned \(8 \times 3 = 24\) points in total from the matches it won and \(1\times5=5\) points in total from the matches it drew. Therefore, it earned \(24+5=29\) points.
B) After \(39\) matches, the team managed to earn \(54\) points in total. \(12\) of these matches have ended in draws. Therefore, this team has won and lost a total of \(39-12=27\) matches. This number includes all matches won and lost. In total, the team earned \(12\times1=12\) points from the \(12\) matches that ended in a draw.
\(54-12=42\) points is the points earned after \(27\) matches. By dividing \(42\) by \(3\) ( because \(3\) points is the score obtained as a result of the matches won), we find how many matches team won. \(42\div3=14\) matches won.
That leaves \(27-14=13\) matches. These represent the matches team lost.
Finally, the answers are below.
\(A)29\)
\(B)13\)
Answer:
a) 29 points
b) 13 losses
Step-by-step explanation:
You want to know points and losses for different teams using the formula P = 3W +D, where W is wins and D is draws.
A 8 wins, 5 drawsThe number of points the team has is ...
P = 3W +D
P = 3(8) +(5) = 29
The team has 29 points.
B 54 pointsYou want the number of losses the team has if it has 54 points and 12 draws after 39 games.
The number of wins is given by ...
P = 3W +D
54 = 3W +12
42 = 3W
14 = W
Then the number of losses is ...
W +D +L = 39
14 +12 +L = 39 . . . substitute the known values
L = 13 . . . . . . . . . . subtract 26 from both sides
The team lost 13 games.
__
Additional comment
In part B, we can solve for the number of losses directly, using 39-12-x as the number of wins when there are x losses. Simplifying 3W +D -P = 0 can make it easy to solve for x. (In the attached, we let the calculator do the simplification.)

The distance of the run is 12meters from the initial point.
Since, we are given the time duration between the two joggers.
So, let suppose from the initial point the length of run is S meters.
Since speed is given in hours, in that case we need to take time in hours also.
Now, we assume first jogger takes t₁ times and second jogger takes t₂ times, in that case using distance -speed formula
=>Distance=Speed × Time
=>Distance/Speed=time
For first jogger
=>S/8=t₁ -----(eq1)
Similarly, for second jogger
=>S/6=t₂----------(eq2)
Subtract both of equations and equating to equal to 1/2hrs,we get

Next Londell needs a total of $400 to buy a new bicycle. He has $40 saved. He earns $15 each week delivering newspapers. How many weeks will Londell have to deliver papers to have enough money to buy the bicycle?
Londell needs to deliver newspapers for 24 weeks to have enough money to buy the bicycle.
Londell currently has $40 saved, and he needs a total of $400 to buy the bicycle. Each week, he earns $15 delivering newspapers.
To calculate the number of weeks Londell needs to work, we can set up an equation:
$40 (current savings) + $15 (weekly earnings) × (number of weeks) = $400 (total cost of the bicycle)
Simplifying the equation:
$40 + $15 = $400
Subtracting $40 from both sides of the equation:
$15 = $400 - $40
$15 = $360
Dividing both sides of the equation by $15:
= $360 / $15
≈ 24
Therefore, Londell will have to deliver newspapers for approximately 24 weeks to have enough money to buy the bicycle.

Ellen wants to purchase a book that is regularly priced at $18. The book is discounted 15%. She also needs to pay a 6% sales tax on the discounted price.
What is the total amount Ellen will pay for the book?
Answer:
Ellen will pay $16.22 for the book.
Step-by-step explanation:
Part 1:
We know that the book Ellen wants to buy has a normal price of $18. However, there is a 15% discount. So, let's calculate 15% of $18.
18 x 0.15 = $2.70
This lets us know that there is a $2.70 discount.
Now, let's subtract the discount from the regular price.
18 - 2.70 = $15.30
So, now we know the discounted price is $15.30
Part 2:
We also know that Ellen has to pay 6% sales tax. The discounted price is 100% of the price, plus 6% is 106%. Let's calculate the tax to figure out the total amount.
15.30 x 1.06 = $16.22 when rounded to the nearest cent.
Therefore, Ellen will pay the total amount of $16.22.
Answer:
$16.22
Step-by-step explanation:
marked price = $18 = 100%
discount = $? = 15%
selling price/ = $? = 85%
discounted price- this price is lower than the marked price as they have given you a DISCOUNT- an amount of money DEDUCTED.(a.k.a selling price)
selling price = 85% x $18 = $15.3= discounted price
100%
sales tax=6%
= 6 x 15.3 = 0.918 = $0.92=sales tax
100
total amount = discounted price + sales tax
= 15.3 + 0.92
= $16.22
