A publisher reports that 54% of their readers own a particular make of car. A marketing executive wants to test the claim that the percentage is actually different from the reported percentage. A random sample of 220 found that 50% of the readers owned a particular make of car. Determine the P-value of the test statistic. Round your answer to four decimal places.

Answers

Answer 1

Answer and explanation:

Null hypothesis: p is not 54%

Alternative hypothesis : p is equal 54%

First find standard deviation

Standard deviation is:

σ = √[ P ( 1 - P ) / n ] = √[ 0.54×0.46/220 ] =0.033

The z score is calculated p-P/σ = (0.54-0.50)/0.033 = 1.2121

Therefore we can conclude that proportions are not same and fail to reject the null hypothesis

Step-by-step explanation:

4x + 3y = -5
-2x+2y = 6

Answers

Answer:

4x + 3y = -5

x = −3 /4 y +  −5 /4

y = −4 /3 x +  −5 /3

-2x+2y = 6

x = y - 3

y = x + 3

Step-by-step explanation:

Solving for x

4x + 3y = -5

4x + 3y + −3y = −5 + −3y

4x = −3y − 5

Then you will divide both sides by 4.

4x /4  =  −3y − 5 /4

x=  −3 /4 y +  −5 /4

Solving for y

4x + 3y + −4x = −5 + −4x

3y = −4x −5

Then you will divide both sides by 3.

3y /3  =  −4x −5 /3

y =  −4 /3 x +  −5 /3

-2x + 2y = 6

Solving for x

−2x+2y+−2y=6+−2y

−2x = −2y + 6

Then you will divide both sides by -2.

−2x/ −2  =  −2y + 6/ −2

x = y − 3

Solving for y

−2x + 2y + 2x = 6 + 2x

2y = 2x + 6

Then you will divide both sides by 2.

2y /2  =  2x + 6 /2

y = x + 3

What is the criteria for similarity of two triangles?

Two triangles are said to be similar when either the ratio of their corresponding sides are equal or all the corresponding angles are equal.

Two similar triangles are the same in shape but not in size.

The given diagram shows two similar triangles as ΔFGH and ΔKJH.

Since the ratios of the corresponding sides of the two triangles are equal, the following equation can be written for the given case as,

(x + 8)/32 = (4x - 25)/52

=> 52(x + 8) = 32(4x - 25)

=> 52x - 128x = -32 × 25 - 52 × 8

=> -76x = -1716

=> x = 22.42

Thus FH = 4x - 25 = 4 × 22.42 - 25 = 64.68

Hence, the length of FH for the given case is 64.68.

Answers

Question:

Consider a cookie recipe in which 1 1/2 cups of chocolate chips are needed to make 25 cookies. Lara wants to double the number of cookies. How many cups of chocolate chips should she use?

Answer:

[tex]Cups = 3[/tex]

Step-by-step explanation:

Given

[tex]Cups = 1\frac{1}{2}[/tex]

[tex]Cookies = 25[/tex]

Required

Number of cups when the cookies is doubled

When [tex]Cookies = 25[/tex], [tex]Cups = 1\frac{1}{2}[/tex]

So, when the number of cookies is doubled, the number of cups will also be doubled.

i.e.

[tex]Cookies = 25*2[/tex]

[tex]Cookies = 50[/tex]

and

[tex]Cups = 1\frac{1}{2} * 2[/tex]

Convert to improper fraction

[tex]Cups = \frac{3}{2} * 2[/tex]

[tex]Cups = \frac{3* 2}{2}[/tex]

[tex]Cups = \frac{6}{2}[/tex]

[tex]Cups = 3[/tex]

i.e. 3 cups are needed

What is a linear equation?

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

The slope of the line is given as,

m = (y₂ - y₁) / (x₂ - x₁)

The graph of a linear function is shown on the grid.

From the graph, the points are (-2.5, 0) and (0, 5) and the y-intercept is 5. The slope of the line is given as,

m = (5 - 0) / (0 + 2.5)

m = 5 / 2.5

m = 2

The slope of the equation is 2. Then the correct option is D.

An angle measures 130° more than the measure of its supplementary angle. What is the measure of each angle?

Answers

Answer:

An angle measures 130° more than the measure of its supplementary angle.

Therefore the required angle is (180°-130°)°=50°

50° is the right answer.

The measure of the angle is A = 50° and the supplementary angles are given by 130° and 50°

What are Supplementary and Complementary Angles?

Supplementary angles are two angles that have a sum of 180°.

Complementary angles are two angles that have a sum of 90°.

Given data ,

Let the first angle be represented as A

Now , the value of A is

Let the second angle be represented as B

And , the value of B is B = 130°

The angles A and B are supplementary

So , A + B = 180°

On simplifying , we get

The measure of A + 130° = 180°

Subtracting 130° on both sides , we get

The measure of angle A = 180° - 130°

The measure of angle A = 50°

Hence , the measure of angle is 50°

y = 8

Step-by-step explanation:

First substitute x with 6 in the equation

Multiple 1/3 with 6, which is 2

2y + 2 = 18

Solve the equation by subtracting 2 from both sides

2y + 2 = 18

    - 2     - 2

You get 2y = 16, so you divide 2 frm both sides

You get y = 8
