The perimeter of the parallelogram is 10units
What is perimeter of a parallelogram?A parallelogram is a quadrilateral with two pairs of parallel sides. The opposite sides of a parallelogram are equal in length, and the opposite angles are equal in measure. Also, the interior angles on the same side of the transversal are supplementary. The Sum of all the interior angles equals 360 degrees.
To obtain the perimeter of the parallelogram , we add all the sides together.
P = 2(l+b)
P= 2( c-2+12-c)
P = 2( c-c -2 +12 )
P = 2( 10)
P = 20

To rewrite the equation in Ax + By = C form, we need to rearrange it so that the x and y terms are on the same side of the equation and the constant is on the other side and the equation become x + 3y = 9.
What is Equation?
An equation is a mathematical statement that shows the equality of two expressions or values. It typically contains one or more variables and an equal sign, which indicates that the expressions on either side of the equal sign have the same value. Equations can be used to represent various relationships between different mathematical objects and are used extensively in many fields of mathematics, science, engineering, and other disciplines. Equations can be solved to find the values of the variables that make the equation true, which is often the goal of many mathematical problems.
To rewrite the equation in Ax + By = C form, we need to rearrange it so that the x and y terms are on the same side of the equation and the constant is on the other side.
Starting with:
y = (1/3)x + 3
We can multiply both sides by 3 to eliminate the fraction:
3y = x + 9
Now we can rearrange to get the x and y terms on the left side:
-x + 3y = 9

Which of the following equations listed below are linear equations?
Answers
Only Equation I is a linear equation. A linear equation is defined as an equation where the highest power of the variable is 1, and the relationship between the variables is a straight line.
What is Straight line?
A straight line is a type of geometric shape that is defined as a line with no curvature, extending infinitely in both directions. In other words, it is a one-dimensional object that extends indefinitely without bending or curving. Straight lines are often represented mathematically as y = mx + b, where m is the slope (or gradient) of the line and b is the y-intercept.The slope determines the steepness of the line, and the y-intercept determines where the line crosses the y-axis. Straight lines play a crucial role in mathematics, especially in geometry and linear algebra.
Only Equation I is a linear equation.
A linear equation is defined as an equation where the highest power of the variable is 1, and the relationship between the variables is a straight line. In Equation I, P is equal to 4 times s, so the highest power of the variable (s) is 1, making this a linear equation.
In Equation II, the right-hand side of the equation contains a single constant ($3), not a variable, and therefore it is not a linear equation.
Equation III is not a linear equation because it is just a constant equal to 2 and does not contain a variable.
So the answer is: 1. Equation I, only.

Write the inequality shown by the shaded region in the graph with the boundary line −5x+2y=−2
Answers
Answer:
Step-by-step explanation:
The boundary line of the shaded region in the graph, which is represented by the equation -5x + 2y = -2, can be used to write the inequality that represents the shaded region. To do this, we first need to determine which side of the boundary line the shaded region is on.
If the shaded region is on the same side of the line as the open half-plane that contains the y-axis, then the inequality is given by:
-5x + 2y > -2
If the shaded region is on the same side of the line as the closed half-plane that does not contain the y-axis, then the inequality is given by:
-5x + 2y ≥ -2
So, the inequality that represents the shaded region depends on the specific context and requirements of the problem, as well as the interpretation of the graph.

A set of data has a mean of 10 and a standard deviation of 3.
(a) Each value in the data set has 6 added to it. Write down the value of
(i) the new mean;
(ii) the new standard deviation.
(b) Each value in the original data set is multiplied by 6.
(i) Write down the value of the new mean.
(ii) Find the value of the new variance.
Answers
Answer:
Step-by-step explanation:
(a) (i) The mean of the original data set is denoted as μ and the constant value being added to each data point is denoted as c.
The formula for the new mean is simply μ + c, so the new mean is μ + 6 = 10 + 6 = 16.
(a) (ii) The standard deviation of the original data set is denoted as σ. Adding a constant value to each data point does not change the spread of the data set, so the new standard deviation is still σ = 3.
(b) (i) The mean of the original data set is denoted as μ and the constant value being multiplied to each data point is denoted as k.
The formula for the new mean is μ * k, so the new mean is μ * 6 = 10 * 6 = 60.
(b) (ii) The variance of the original data set is denoted as V. To find the new variance after multiplying each data point by k, we can use the formula: k^2 * V.
So, the new variance is 6^2 * V = 36 * V.
--------
Here is a definition of each variable:
μ: The mean of a set of data is the sum of all the values divided by the number of values. It represents the average value of the data set.
σ: The standard deviation of a set of data is a measure of the spread of the data set about the mean. It is the square root of the variance.
V: The variance of a set of data is the sum of the squares of the deviations of each value from the mean, divided by the number of values. It is a measure of the spread of the data set about the mean, but it is measured in squared units.
c: A constant value added to each data point.
k: A constant value multiplied to each data point.

Answers
The percentage of middle school students that prefer each season and the percentage of high school students that prefer each season is 57.93% and 42.07% respectively.
What is the percentage?The percentage is the ratio of the composition of value to the overall composition of value multiplied by 100.
Here,
Total number of students = 93 + 31 + 36 + 54 = 214
The percentage of students in middle school prefer spring,
= number of students in middle school prefer spring / total student × 100%
= 93/214 × 100%
= 43.45%
Similarly,
The percentage of students in middle school prefer winter,
= number of students in middle school who prefer winter/ total students × 100%
= 31/214 × 100%
= 14.48%
Thus, the percentage of middle school students that prefer each season and the percentage of high school students that prefer each season are 43.45 + 14.48 = 57.93% and 100-57.93% = 42.07%.

Yasmin is participating in a 5-day cross-country biking challenge. She biked for 45,60,68 and 52 kilometers on the first four days. How many kilometers does she need to bike on the last day so that her average (mean) is 58 kilometers per day?
Answers
Step-by-step explanation:
The total distance biked by Yasmin on the first four days can be calculated as follows:
45 + 60 + 68 + 52 = 225 km
To find out how many kilometers she needs to bike on the last day to achieve an average of 58 km per day over the 5 days, we can set up an equation based on the formula for the mean:
(45 + 60 + 68 + 52 + x) / 5 = 58
Where x is the number of kilometers Yasmin needs to bike on the last day. Expanding the equation:
225 + x = 5 * 58
225 + x = 290
Subtracting 225 from both sides:
x = 65
So Yasmin needs to bike 65 kilometers on the last day to achieve an average of 58 kilometers per day over the 5 days

As part of a larger experiment, Dale (1992) looked at six samples of a wetland soil undergoing a simulated snowmelt. Three were randomly selected for treatment with a neutral pH snowmelt; the other three got a reduced pH snowmelt.

Use mathematical notations. (b) 2 points We want to test whether the two treatments have equal average numbers of Copepoda. Write the n and the alternative hypotheses using the notations defined in the previous question (c) 5 points We want to perform a t-test. What assumptions are you making?

(d) 5 points) Using a randomization-based analysis, test the nul hypothesis that the two treatments have equal average numbers of Copepoda versus a two-sided alternative. Use a level of significance v = 0.05.
Answers
(a) The mathematical notations is (xₙ, yₙ)
(b) The alternative hypotheses using the notations defined in the previous question is t = (Xₙ - Yₙ) / SE
(c) The assumptions making is variances of the two populations are equal.
A hypothesis is a tentative explanation or prediction of a phenomenon, and it is essential in scientific research. In this study, we have two hypotheses:
Null Hypothesis: There is no significant difference in the average number of Copepod between the reduced pH and neutral pH snowmelt treatments.
Alternative Hypothesis: There is a significant difference in the average number of Copepod between the reduced pH and neutral pH snowmelt treatments.
Model:
A model is a mathematical representation of a phenomenon, and it is used to make predictions or explanations. In this experiment, we can create two simple models:
Model for Neutral pH Snowmelt:
Let Yₙ be the number of Copepod in a microcosm treated with neutral pH snowmelt. Then, Yₙ follows a normal distribution with mean µn and standard deviation σn.
Model for Reduced pH Snowmelt:
Let Yₙ be the number of Copepod in a microcosm treated with reduced pH snowmelt. Then, Yₙ follows a normal distribution with mean µr and standard deviation σr.
Assumptions:
Before conducting a t-test, we must ensure that the data satisfies the following assumptions:
The sample is a random and representative sample of the population.
The data is normally distributed.
The variances of the two populations are equal.
The test statistic for the t-test is:
t = (Xₙ - Yₙ) / SE
where Xₙ is the sample mean of neutral pH snowmelt, Yₙ is the sample mean of reduced pH snowmelt, and SE is the standard error.
Assuming a level of significance v = 0.05, we have a critical value of t = 2.306 for a two-tailed test with 4 degrees of freedom. If our calculated t-value is greater than 2.306 or less than -2.306, we reject the null hypothesis.
We can perform a randomization test as follows:
If the p-value is less than 0.05, we reject the null hypothesis and conclude that there is a significant difference in the average number of Cope pod between the reduced pH and neutral pH snowmelt treatments. If the p-value is greater than 0.05, we fail to reject the null hypothesis.

What is a rotation?In Geometry, the rotation of a point 90° about the center (origin) in a counterclockwise (anticlockwise) direction would produce a point that has these coordinates (-y, x).
By applying a rotation of 90° counterclockwise to the vertices for D, the coordinates of the vertices of the image point D' are as follows:
(x, y) → (-y, x)
Ordered pair A = (-3, 4) → Ordered pair A' = (-4, -3)
Ordered pair B = (-5, -1) → Ordered pair B' = (1, -5).
Ordered pair C = (-1, 2) → Ordered pair C' = (-2, -1).

Find an equation for the perpendicular bisector of the line segment whose endpoints are (−2 ,− 9) and (−6,7). PLSLLSLS
Answers
The equation of the perpendicular bisector of the line segment joining (-2, -9) and (-6, 7) is y = (-1/4)x - 2
What is the slope of the line?The slope of the line is a tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.
Here,
The midpoint of the line segment joining (-2, -9) and (-6, 7) can be found using the midpoint formula:
Midpoint = ( (x₁+x₁)/2 , (y₁+y₁)/2 )
Midpoint = ( (-2-6)/2 , (-9+7)/2 )
Midpoint = (-4,-1)
Next, we need to find the slope of the line joining the two points (-2, -9) and (-6, 7). We can do this using the slope formula:
Slope = (y₂ - y₁) / (x₂ - x₁)
Slope = (7 - (-9)) / (-6 - (-2))
Slope = 4
The slope of the line perpendicular to the line segment is the negative reciprocal of the slope of the line joining the two points. So the slope of the perpendicular line is -1/4.
Using the point-slope form of a line, the equation of the perpendicular bisector can be written as:
y - y₁ = m(x - x₁), where (x₁, y₁) is the midpoint and m is the slope of the line.
Plugging in the values we found, we get:
y - (-1) = (-1/4)(x - (-4))
y + 1 = (-1/4)(x + 4)
y + 1 = (-1/4)x - 1
y = (-1/4)x - 2
Therefore, the equation of the perpendicular bisector of the line segment joining (-2, -9) and (-6, 7) is y = (-1/4)x - 2.

Graph the line with slope 2 passing through the point (-3, -4).
Answers
The solution is, the equation is y=2/3x.
What is meant by graph?In math, a graph can be defined as a pictorial representation or a diagram that represents data or values in an organized manner. The points on the graph often represent the relationship between two or more things.
A diagram representing a system of connections or interrelations among two or more things by a number of distinctive dots, lines, bars, etc.
here, we have,
so the line is in slope intercept form
y=mx+b, m=slope and b=y intercept
we know the slope so just solve for b
y=2/3x+b
subsitute
3 for x and 2 for y
2=2/3(3)+b
2=2+b
subtract 2 from both sdies
0=b
so the equaiton is
y=2/3x+0 or just simply
y=2/3x
here is the graph
just input values for x and get y values exg
x=3 y=2
x=6 y=4
x=0 y=0
x=-3 y=-2

What is function?The subject οf mathematics includes quantities and their variatiοns, equations and related structures, shapes and their locations, and places where they can be fοund.
The term "functiοn" refers to the relationship between a set of inputs, each of which has an associated output. A cοnnection between inputs and outputs in which each input leads to a single, distinct result is known as a functiοn.
Each function is given a dοmain and a codomain, or scope. Usually, f is used to denote functiοns (x). input is an x. There are fοur main types of functions accessible. based οn the following factors: οn functions, one-to-one functions, many-tο-one functions, inside functiοns, and on functions.
The functiοn will be
h(4)=2(4²)-4
=32-4
=28
h(5)=2(5²)-5
=50-5
=45
Net change is 45-28 = 17
average rate of change = 17/1 = 17

What is trigonometry?
Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
here, we have.
tan∅/(1+ sec∅)
=(sin∅/cos∅)/(1+ sec∅) [tan∅=(sin∅/cos∅)]
=(sin∅/cos∅)/(1+1/cos∅)
=sin∅/1+cos∅
multiplying both numerator & denominator by 1-cos∅, we get,
=sin∅(1-cos∅)/ sin^2∅
=(1-cos∅)/sin∅
=cosec∅ - cot∅

petra jogs 60 miles in 110 minutes, at this rate how long would her take to jog per one minutes
Answers
The speed of Petra will be 0.55 mile/minute.
What exactly is speed?
The definition of speed is:
The pace at which an object's location changes in any direction.
Speed is defined as the ratio of distance travelled to time spent travelling. Because it has just one direction and no magnitude, speed is a scalar number.
Formula for Speed
The speed formula is shown below:
s=d/t
Where,
s is the speed in metres per second, d is the distance travelled in metres, and t is the duration in seconds.
Now,
As given petra jogs 60 miles in 110 minutes
then in one minute she will jog =60/110 mile
=0.5454 mile/min
Hence,
The speed of Petra will be 0.55 mile/minute.

Which of the following is true about this argument? o A The premise entails the conclusion because, if the premise is true, the conclusion has to be true B The premise does not entail the conclusion because, if the premise is true, the conclusion could still be false (setting aside facts not supplied by the premise) O с The premise entails the conclusion because, setting aside facts not supplied by the premise, there is no way the premise could be true and the conclusion false. D The premise does not entail the conclusion because it has no suppositional strength.
Answers
The true argument is option B) The premise does not entail the conclusion because, if the premise is true, the conclusion could still be false
The argument presented lacks logical reasoning and does not provide enough information to support the conclusion. The premise that "Bob is 13 feet tall" is a factual statement, but it is not sufficient to conclude that "Bob is taller than most other people." Without further information about the height distribution of people.
It is impossible to make such a conclusion based solely on Bob's height. Additionally, the argument does not provide any logical reasoning to connect the premise to the conclusion, so it is not a valid deductive argument.
Therefore, the correct option is (B)
