The answer is 24.

Answer 2

Answer:

24

Step-by-step explanation:

Plug in the value of t: 4(7 - 1)We can solve this two ways: one way is doing the distributed property, the other is PEMDAS. For now, let's use the distributed property (the other person who answered used PEMDAS)4 × 7 = 284 × 1 = 4Put them together: 28 - 428 - 4 = 24

I hope this helps!

IN triangle DEF, DE is congruent to FD and m

Answers

Answer:

The measure of angle E is 55°

Step-by-step explanation:

In an isosceles triangle, the vertex angle is the angle including between the two equal sides, the base angles are the other angles of the triangle, the base angles are equal in measures

In triangle DEF

DE is congruent to FD

∴ The length of DE = the length of FD

∵ ∠D is the angle including sides DE and FD

∴ ∠D is the vertex angle

∠F and ∠E are the base angles

∵ The base angles of the isosceles triangle are equal in measures

m∠F = m∠E

∵ m∠F = 55°

∴ m∠E = 55°

The measure of angle E is 55°

The histograms below summarize the average travel time to work for random samples of 70
workers in the Los Angeles area and 61 workers in the New York City area.
(a) Briefly compare the distributions of travel times for these two regions.
(b) Suppose you wanted to make the point that typical travel time is longer in the New York City area than in the Los Angeles area. Which measure of center would you use? Justify
your answer.

Answers

Answer:

(a) The travel times of the Los Angeles workers have a higher variability than those of the New York City area and about 54 out the 70 Los Angeles workers take longer (over 20minutes) than the maximum travelling time for the New York City workers (18 minutes) when they travel to work

(B) (i) The percentage of workers that travel close to the maximum travel times given in the data of the two cities

(ii) Almost half of the New York City area workers spend between 40 and 100 minutes to work, while almost half (32) of the Los Angeles workers spend between 0 and 20 minutes to work every day

Step-by-step explanation:

The travel times for the 70 Los Angeles workers are;

Number of workers                    [tex]{}[/tex]         Travel time

32                    [tex]{}[/tex]                                      0 - 20 minutes

10                   [tex]{}[/tex]                                        40 - 60 minutes

4                   [tex]{}[/tex]                                          60 - 80 minutes

2                   [tex]{}[/tex]                                          80 - 100 minutes

The travel times for the 61 New York City area workers are;

18                   [tex]{}[/tex]                                          0 - 20 minutes

14                   [tex]{}[/tex]                                          20 - 40 minutes

10                   [tex]{}[/tex]                                          40 - 60 minutes

12                   [tex]{}[/tex]                                          60 - 80 minutes

Workers in Los Angeles averagely take short time to reach to workplace than in New  York.

Descriptive statistics like mode, IQR, skewness etc do care about how the data is more leaning on one side than other. That is why these types of measures are helpful here.

Given data includes:

For Los Angeles: 32, 22, 10, 4, 2 (skewed left)

For New York: (18, 14, 10, 12 ,7) (very slightly skewed left)

Part a.

Comparing the distributions of travel times for both of the regions:

Histogram of Los Angeles is more skewed to the left. (values like 32, 20 lies on the left, and 5, 2 on the right tail)

Histogram of New York, in comparison to the histogram of Los Angeles is not that skewed and lies approximately leveled but is slight skewed to left.

This hows that time taken by worker to travel in Los Angeles is averagely very  short and count of workers taking longer time falls dramatically.

On the other hand, that above thing doesn't happen for workers in New York.

Part b.

Central measure "Mode" can be used here. The reason of choosing mode is that it focuses on frequency and gives weights to outliers too. Mean, on the other hand takes average of all values thus might forget the data of skewness.

The 3rd moment of measure of skewness can be used to measure the degree of skewness in both the data.

Inter Quartile Range is also useful since it will tell quartile to quartile measures which can help not loose the data of skewness.

So, the important thing that should be included in the measure we use to  describe this data is to include the information of skewness of the graph.

Descriptive statistics like mean, standard deviation etc forget about skewness.

Descriptive statistics like mode, IQR, skewness etc do care about how the data is more leaning on one side than other. That is why these types of measures are helpful here.

James completely covered a square poster board using 68.2 in. of cardstock. Which measurement is
closest to one side of the poster board in inches?
Answer?

Answers

Answer:

17inches

Step-by-step explanation:

If James completely covered a square poster board using 68.2 in. of cardstock, this means that the perimeter of the square box is 68.2in.

To get the measurement if one side if the box we will use the formula for finding the perimeter of the square.

P = 4L

L is side length of the square box

68.2 = 4L

L = 68.2/4

L = 17.05in

.hence the measurement closest to one side of the square box is 17inches

x = 6

Step-by-step explanation:

Since the triangles are congruent, then corresponding sides are congruent, that is

QS = TV , substitute values

6x + 12 = 9x - 6 ( subtract 6x from both sides )

12 = 3x - 6 ( add 6 to both sides )

18 = 3x ( divide both sides by 3 )

6 = x

Answer:

x = 6

Step-by-step explanation:

x = ?

6x + 12 = 9x - 6

get the variables and numbers on different sides

6x + 12 - 6x = 12

9x - 6 + 6 = 9x

12 + 6 = 18

9x - 6x = 3x

3x = 18

divided each side by 3

3x / 3 = x

18 / 3 = 6

x = 6

Which equation is parallel to y = –3 x + 4 and passes through the point (–3 , 4)?

Answers

The equation given has a slope of -3. See it? The equation we are looking for must have the same slope because the lines are parallel to each other. This means the lines never meet or touch on the xy-plane.

We use the point-slope formula to find the equation.

Here is the point-slope formula:

y - y_1 = m(x - x_1)

y - 4 = -3(x - (-3))

y - 4 = -3(x + 3)

y - 4 = -3x - 9

We now isolate y to find our equation.

y = -3x - 9 + 5

y = -3x - 4

Done.

Following are the calculation to the given line which is parallel:

Given:

[tex]\bold{ line: \ y=-3x+4}\\\\\bold{ point: (-3,4)}[/tex]

Given rectangle QUAD, If DU = 5x - 4 and QP = 2x + 7, then find the length of DU.

Answers

Answer:

DU = 86

Step-by-step explanation:

Properties of a rectangle,

- Opposite sides are equal in measure.

- Diagonals of a rectangle are equal.

- Diagonals bisect each other.

In the given rectangle QUAD,

Diagonals AQ and DU bisect each other at P.

AQ = DU

2(QP) = DU [Since, AQ = 2(PQ)]

2(2x + 7) = 5x - 4

4x + 14 = 5x - 4

5x - 4x = 14 + 4

x = 18

Since, DU = 5x - 4

DU = 5(18) - 4

     = 90 - 4

     = 86

Therefore, measure of DU = 86 units

The image of (6, 9) under a dilation is (4, 6).

The scale factor of the dilation is ________.


Type a numerical answer in the space provided. If necessary, us the / key to represent a fraction bar.

Answers

Answer:

2/3

Step-by-step explanation:

The scale factor is the number that the original image is multiplied by to find the new image. So, we have to find what number multiplied by 6 equals 4 and what number multiplied by 9 equals 6. This can represented as an equation, with the unknown number represented by x:

6 * x = 4

6x = 4

Divide both sides by 6 to isolate x:

6x/6 =4/6

x = 4/6 = 2/3

x = 2/3

9x = 6

9x/9 = 6/9

x = 6/9 = 2/3

x = 2/3

For both dilations x came out to be 2/3. So, the scale factor is 2/3.

Answers

Answer:

The answer to this question is given below in the explanation section.

Step-by-step explanation:

The table shows three different recipes. In this question, it is asked that will all the recipes taste same. To obtain the answer to this question, first, we measure the taste of each recipe in terms of calculating the ratio.  

Water ............................. Cups

     1   ............................. 3

    4   ............................. 12

    6   ............................. 18

1. The fraction of the first recipe is 1/3 so the ratio is 1:3(water to cup)

2. The fraction of the second recipe is 4/12

which can be simplified as 4/12=1/3 so the ratio is 1:3(water to cup)

3. The fraction of the third recipe is 6/18

which can be simplified as 6/18 = 3/9 = 1/3 so the ratio is 1:3(water to cup).

So based on the above answer, all recipes taste the same.

Answer 2:

No recipe taste different, all the recipe taste the same. Because all the recipe ratios are equivalent.
