Answer:

Step-by-step explanation:

The trick is to think of these as fractions and multiplying them instead of dividing them.

Since dividing things is the same as multiplying by it's reciprocal, so something like

[tex]\frac{4}{y+2}[/tex]

turns into

[tex]\frac{4}{1} *\frac{1}{y+2}[/tex]

Following this concept,

[tex]\frac{4}{1} *\frac{1}{y+2-3}*\frac{1}{y-2+12}*\frac{1 }{y^{2} -4}[/tex]

and then

[tex]\frac{4}{1} *\frac{1}{y-1}*\frac{1}{y+10}*\frac{1 }{y^{2} -4}\\[/tex]

Now we'll have to multiply out everything like this

[tex]\frac{4}{(y-1)(y+10)(y^2-4)}[/tex]

so it becomes

[tex]\frac{4}{(y^2-9y-10)(y^2-4)}[/tex]

which turns into

[tex]\frac{4}{y^4-9y^3+22y^2+40}[/tex]

And there you have it as a single fraction.

The slope of the taxi fare is a positive slope.

Distance is a measure of the space between two points. It is the length of a physical path between two points, usually measured in units of meters or kilometers. Distance can also refer to the amount of time or energy it takes to travel between two points. Distance is a fundamental concept in physics, mathematics, and other scientific fields. Distance can also be used to measure relationships between people, such as the distance between two people's homes.

The x-axis would represent the distance, while the y-axis would represent the fare. As the distance increases, the fare increases at a rate of 2 dollars for every additional 1 km.

Answer: b i think

Step-by-step explanation:

The taxes paid for each taxable income is given as follows:

a. $400,000: $113,775.

b. $10,954: $1,095.4.

c. $108,962: $18,904.88.

d. $209,850: $47,222.5.

The amount of taxes is obtained identifying the correct interval in the table and then applying the proportions.

For a taxable income of $400,000, the tax is of $45,210 plus 35% of the income ​over $204,100, hence:

45210 + 0.35(400000 - 204100) = $113,775.

For a taxable income of $10,954, the tax is a simple 10%, hence:

0.1 x 10954 = $1,095.4.

For a taxable income of $108,962, the tax is of 12962 plus 24% over 84,200, hence:

12962 + 0.24 x (108962 - 84200) = $18,904.88.

For a taxable income of $209,850, the tax is of $45,210 plus 35% of the income ​over $204,100, hence:

45210 + 0.35(209850 - 204100) = $47,222.5.

Recapping, we identify between which two values the taxable income is located, and then apply the tax rule defined by the table for the range in which the income is located.

so correlation coefficient = σ^XY/σ^Xσ^Y = 1.225 / 1.36 = 0.9

Step-by-step explanation:                                                                          

a) We need to find the conditional p m f of X when Y = 1.

So, when Y = 1, there are only two X values: X =1 and X =2.

X can have any of the following values: 0, 1, 2, or 3                                                                                                        

so P(0) = 0/ 0.2 = 0          

P(1) = 0.1/(0.1+0.1) = 0.5

P(2) = 0.1/( 0.1+ 0.1) = 0.5

P(3) = 0/ 0.2 = 0

b)  The correlation coefficient of X and Y isρXY              

ρ^XY=(X,Y)=(X,Y)/σ^Xσ^Y=σ^XY/σ^Xσ^Y

We will calculate σ^X first by μ^x

f x(x) = 0.2; x = 0

= 0.2; x =1

= 0.2 ; x = 2

= 0.4 ; x = 3

μ^x = 0.2 * 0 + 0.2 * 1 + 0.2 * 2 + 0.4 * 3 = 1.8

σ^X^ 2 = 0.2 * 1.82 + 0.2 * 0.82 + 0.2 * 0.22 + 0.4 * 1.22 = 1.36

σ^X = 1.166

We will calculate σ^y first by μ^y

f^ x (X) = 0.2; y = 0

= 0.2; y =1

= 0.2 ; y= 2

= 0.4 ; y = 3

μ^y = 0.2 * 0 + 0.2 * 1 + 0.2 * 2 + 0.4 * 3 = 1.8

σ^y^ 2 = 0.2 * 1.82 + 0.2 * 0.82 + 0.2 * 0.22 + 0.4 * 1.22 = 1.36

σ^y = 1.166

Now we will calculate σ^XY

σ^2^XY = 0.4 * ( 3 - 1.8)* ( 3-1.8) + 0.2 *( 0 -1.8) * ( 0 - 1.8) + 0.1 * ( 1- 1.8) * ( 1- 1.8) + 0.1 * ( 2 -1.8) * ( 1 -1.8) + 0.1 * ( 1 - 1.8) * ( 2 - 1.8) + 0.1 * ( 2 - 1.8) * ( 2 - 1.8) = 1.26

σ^XY = 1.225        

so correlation coefficient = σ^XY/σ^Xσ^Y = 1.225 / 1.36 = 0.9

The perimeter of the triangle is 7x + y -4 feet. The correct option is B.

A closed shape's perimeter is the sum of the lengths of its outside boundaries. The lengths of all the sides are added to determine the measurement.

Given:

The sides of the triangles are 4x+5 feet, y-7 feet and 3x-2 feet.

To find the perimeter:

The perimeter of the triangle is the sum of all the sides of the triangle.

So, the perimeter = (4x+5) + (y-7) + (3x-2)

The perimeter = 4x+5 + y-7 + 3x-2

The perimeter = 4x + 3x + y +5 -7 -2

The perimeter = 4x + 3x + y +5 -9

The perimeter = 7x + y -4 feet.

Step-by-step explanation:

S(48) = (48/2)(2a+47d),

S(36) = (36/2)(2a+35d).

Now S(48) = 4S(36)

24(2a+47d) = 4*18(2a+35d) = 72(2a+35d).

Then 2a+47d = 3(2a+35d) and

6a +105d -2a -47d = 0,

4a +58d = 0,

2a+29d = 0.

Now S(30) = (30/2)(2a+29d) = (15)(2a+29d)=0

The pattern represented by the scatter plot in Graph A are as follows;

1. a) The pattern of the graph with a scale factor of 1 unit equivalent to 1 y-value is the y-value at a point is 1 + the x-value at the specified point

b) When the scale factor is changed to 0.1 y-value unit to each unit of the graph, the pattern is each y-value is 0.1 × the x-value at the point plus 0.1

A scatter plot is the plot of variable pairs along the two axis of a coordinate plane such that the pattern formed indicates the correlation between the values.

1. a. The values of the coordinate points of the Graph A using a scale of 1 to 1 unit of the graph are; (1, 2), (2, 3), (3, 4), (4, 5), (5, 6)

A pattern of the graph can be obtained by finding the value of the x and y values as follows;

The first difference in the y-values that is constant indicates, that the relationship is a linear relationship

The slope of the graph is; (3 - 2)/(2 - 1) = 1

The equation of the graph is therefore; y - 2 = 1 × (x - 1) = x - 1

y = x - 1 + 2 = x + 1

y = x + 1

The pattern is therefore, each value of y is equivalent to the value of x + 1

(b) Changing the scale of 1 unit on the graph to 0.1 unit of the y-value, we get; (1, 0.2), (2, 0.3), (3, 0.4), (4, 0.5), (5, 0.6)

Therefore, the slope of the graph is; (0.3 - 0.2)/(2 - 1) = 0.1

The equation of the graph is therefore; y - 0.2 = 0.1 × (x - 1)

y - 0.2 = 0.1 × (x - 1)

y - 0.2 = 0.1·x - 0.1

y = 0.1·x - 0.1 + 0.2 = 0.1·x + 0.1

y = 0.1·x + 0.1
The pattern represented by the graph after the scale is changed to a decimal value of 0.1 y-value to 1 unit of the graph is; y = 0.1·x + 0.1

Which is each y-value is 0.1 + the product of the x-value and 0.1

Answer:

The y-intercept is -2.

Step-by-step explanation:

The line intersects at the y-axis on the point (0, -2).

The equation of the line that passed through the points, can be found to be y = -4 x + 1

The equation of a line takes the form:

y = mx + b

m = slope

b = y - intercept

The slope is:

= ( Y2 - Y1 ) / ( X 2 - X 1 )

Given the points, (-1,5) and (2,-7), the slope is:

= ( - 7 - 5 ) / ( 2 - ( - 1 ))

= - 12 / 3

= - 4

The y - intercept can be found by plugging in the slope and the value of a point into the equation:

- 7 = -4 ( 2 ) + b

b = -7 + 8

b = 1

Considering the expression of a line, the equation of the line that passes through the points (-1,5) and (2,-7) is y= -4x +1.

A linear equation o line can be expressed in the form y = mx + b

where

Knowing two points (x₁, y₁) and (x₂, y₂) of a line, the slope of the line can be calculated as:

m= (y₂ - y₁)÷ (x₂ - x₁)

Substituting the value of the slope m and the value of one of the points in  y = mx + b, the value of the ordinate to the origin can be obtained.

In this case, being (x₁, y₁)= (-1, 5) and (x₂, y₂)= (2, -7), the slope m can be calculated as:

m= (-7 - 5)÷ (2 - (-1))

m= (-7 - 5)÷ (2 + 1)

m= (-12)÷ 3

m= -4

Considering point 1 and the slope m, you obtain:

5= (-4)× (-1) + b

5= 4+b

5 -4= b

1= b

Finally, the equation of the line is y= -4x +1.

What is probability ?

Probability can be defined as the ratio of number of favourable outcomes and total number of outcomes.

This is a case of conditional probability. The conditional probability of an event, A given that B has occurred is is written as P(AIB). We would calculate the probability as

P(AIB) = Probability of A and B/Probability of B

Looking at the given question, Probability of S and F is 12/21 (12 of the students in the class passed both quizzes)

Probability of S = 19/21

Therefore,

P(SIF) = (12/21) / (19/21)
