This is my method.
Take two points.
(X₁ = -8, Y₁ = 8)
(X₂ = -3, Y₂ = 4.875 or 4 7/8)
Equation of a straight line:
y = mx + b ------(i)
Step 1: Calculating Slope (m).
[tex]\frac{y_2-y_1}{x_2-x_1 }[/tex]
[tex]\frac{4.875-8}{-3--8}[/tex]
[tex]\frac{-3.12500}{5}[/tex]
[tex]m=-0.625[/tex]
Now putting value of m in equation (i)
y = -0.625x + b -----(ii)
Step 2: Calculating Y-intercept (b).
Lets choose the first point, (-8,8) for calculating y-intercept:
y = mx + b
8 = -0.625(-8) + b
8 = 5 + b
3 = b
b = 3
Now putting value of b in equation (ii)
y = -0.625x + 3
This is slope-intercept form, now let's convert to point-slope formula.
⇒ [tex]y-2.375=-0.625(x-1)[/tex]
For what value of k are the graphs of 12y = 9x + 8 and 4y = k(x + 4) parallel?
perpendicular? I HAVE THE ANSWER, just need step to step explanation on how to solve it (pls be clear, answers in pic)
Answer:
parallel: k = 3perpendicular: k = -16/3Step-by-step explanation:
You want to know the values of k that make the line 4y = k(x +4) either parallel or perpendicular to the line 12y = 9x +8.
ParallelThe slopes of parallel lines are the same. When the equation of a line is written in "y =" form, the slope is the coefficient of x. Here, the two equations written in that form are ...
y = k/4x +1y = 3/4x +2/3For parallel lines, we want to choose the value of k so that the slopes are equal:
k/4 = 3/4
k = 3 . . . . . . . . multiply by 4
PerpendicularThe slopes of perpendicular lines have a product of -1. This means we want to choose k so that ...
(k/4)(3/4) = -1 . . . . . the product of slopes k/r and 3/4 is -1
k = -16/3 . . . . . . . . . multiply by 16/3

Manas is half his sister's age.
She is eight years younger than
Uncle Mike. Mike is the sum of a
dozen and a score.
In how many years time will the sum of Manas' age and his
sister's age be 48 years?
Answer: In 6 years the sum of Manas' age and his sister's age will be 48 years.
Step-by-step explanation:
We know that value of a dozen is 12 and the score is 20.
Hence,
Uncle Mike's age = 12+20 = 32 years
Since Manas' sister is 8 years younger than Mike,
Her age = 32 - 8 = 24 years
We know that Manas is half her age. Therefore,
Manas' age = 24 ÷ 2 = 12 years
After x years the sum of Manas' age and his sister's age will be 48 years.
Manas' future age = (12 + x) years
His sister's future age = (24 + x) years
The Sum of their ages is 48 years. Hence,
(24 + x) + (12 + x) = 48
36 + 2x = 48
2x = 48 - 36
2x = 12
x = 12 ÷ 2
x = 6
Therefore, in 6 Years sum of their ages is 48 years.

y = mx + c .....(i)
Putting x =21 and y = 1517 in the equation (i)
1517 = 21m + c ...(ii)
Putting x = 47 and y = 2609 in the equation (i)
2609 = 47m + c ...(iii)
Subtract equation (ii) from (iii)
47m + c =2609
21m + c = 1517

How to calculate the length of the hypotenuse ?The Pythagorean theorem, sometimes known as Pythagoras' theorem, is a basic relationship between a right triangle's three sides in Euclidean geometry. According to this rule, the areas of the squares on the other two sides add up to the area of the square whose side is the hypotenuse, or the side across from the right angle. This theorem can be expressed as the Pythagorean equation, which is an equation relating the lengths of the sides a, b, and the hypotenuse c:

The value for df within in an experiment with two levels of factor a and three levels of factor b and five samples for each treatment condition is between 3.
Explain the term levels of factor?In a two-way ANOVA, the 2 separate variables are known as factors. Two variables, or factors, are supposed to influence the dependent variable. There will be two or even more levels inside each factor, and there are one less degrees of freedom per factor than there are levels.Let n1 represent factor A's level of freedom.
Let n2 represent factor B's degree of freedom.
If factor A has five levels, then n1 = 2.
If Factor B has seven levels, then n2 = 3.
The formula is used to express how the degrees of freedom interact;
df = (n1 - 1)+(n2 - 1) (n2 - 1)
df = n1 -1 + n2- 1
df = n1 + n2 -2
Replace n1 and n2 to obtain df;
df = 2 + 3 - 2
df = 3

Polynomials can be thought of as a type of mathematics. Nearly all branches of mathematics employ them to express numbers, and calculus is one of those branches where they play a crucial role.
A specific kind of expression is a polynomial. A mathematical statement without the equals symbol (=) is called an expression.
An algebraic expression known as a polynomial requires that all of its exponents be whole numbers.
Any polynomial must have variable exponents that are non-negative integers.
Although a polynomial contains variables and constants, we are unable to divide a polynomial by a variable.

The system of equation is inconsistent as these three equations does not give any solution.
How to solve three variable equations?
In comparison to equations with two variables, a three-variable linear equation requires a little more work to solve. The extra variable is the cause of this complexity.
Even if there are various ways to solve this kind of equation, the elimination technique is still the simplest.
To solve three variable linear equations using the elimination approach, follow these steps:
1. Avoid using fractions and decimals and write all the equations in standard form.
2. Pick an appropriate variable to remove.
3. Remove the chosen variable from any two of the three equations.
4. Choose another set of the two equations, and then take the same chosen variable out.
5. For the two variables they each include, solve the two equations from stages three and four.
6. Replace the answer in fifth step.
7. Reverify by putting them again in the equation.
So according to these given Equations we have to find the value of x, y and z respectively,
-2x + 15y + z = 44
4x + 3y + 3z = 18
-3x+6y-z = 8
After solving these three equations we do not get any solutions.
Hence the system of equations is inconsistent.

The smallest residual is 14, and the largest residual is 51. The largest residual does not correspond to an outlier in the data.
C)
The smallest residual is 18, and the largest residual is 45. The largest residual corresponds to an outlier in the data.
D)
The smallest residual is 18, and the largest residual is 45. The largest residual does not correspond to an outlier in the data.
Based on the information provided, the correct statement is: The smallest residual is 14, and the largest residual is 51. The largest residual corresponds to an outlier in the data.
A residual is the difference between the actual value of the dependent variable (in this case, the number of customers) and the predicted value of the dependent variable based on the model (in this case, the line of fit). In other words, it is the error or deviation between the observed data and the model.
In this case, the smallest residual is 14, and the largest residual is 51. This means that the model is most accurate when predicting the number of customers on days with temperatures close to 82°F and least accurate when predicting the number of customers on days with temperatures close to 91°F. The large residual of 51 corresponds to an outlier in the data, which means that the model is not a good fit for this data point and may not accurately predict the number of customers on days with temperatures close to 91°F.
Option A is correct because it correctly describes the range and magnitude of the residuals and identifies the largest residual as corresponding to an outlier in the data. Options B, C, and D are all incorrect because they either do not correctly describe the range or magnitude of the residuals or do not correctly identify the largest residual as corresponding to an outlier in the data.
