Towards the end of the Ming Dynasty, a capitalist production system was gradually developing. The Ming Dynasty achievements resulted in many entrepreneurs readily seizing economic development opportunities building the great wall. One of the most significant Ming Dynasty achievements in engineering is the completion and repair of the Great Wall. Ming, The restoration of the Grand Canal was also an important achievement of this era. A wide range of machinery and equipment from which silk and cotton looms were made were invented during this era.  Dynasty achievements also included significant contributions in the fields of philosophy, art, and literature.

Answer:

80°

Step-by-step explanation:

In rhombus, opposite angles are equal. i.e <KET = <KIT

Triangle KET is isoceles, which means both parts of angle E are equal.

Angle E = 40 + 40

Angle E = 80

If angle E is 80 than Angle I is also 80.

Answer:

x=135

Step-by-step explanation:

The two angles are supplementary, meaning they both add up to 180°.

So to find the value of one angle, simply subtract 50 from 180.

180-50=130

So now we know that 130 is equal to the expression.

x-5=130

Add 5 to both sides.

x=135

Answer:

342yd^2

Step-by-step explanation:

Hope this helps!

Answer:

342yd^2

Step-by-step explanation:

The way I find surface area is by laying out the box and finding the area of each square seperately and then adding them together.

First, I placed the 7 on the wing to the side because that is the width.

Next, I placed the 13 on the long side of the big box because that is the length.

Then, I placed the 4 on the small side of the big box because that is the width.

After that I just did the multiplication for each box.

2(7•13) + 2(7•4) + 2(13•4) = 342

You can apply this same strategy to any surface area problem like this. The format will change based on the shape but that's pretty much it. Hope this helped

Answer:

67.9 min < μ < 113.5 min

Step-by-step explanation:

Calculation to determine the confidence interval estimate

First step is to find alpha (α/2)

α =1-0.98

α=0.02/2

α= 0.01

Second step is to determine ± zα/2

z-score of 1.0000 - 0.0100 = .9900 using normal distribution table

z-score = ± 2.33

Now Let determine the confidence interval estimate using this formula

X ± zα/2(σ/√n)

Where,

Confidence Interval (CI) = .98

X = 90.7

n = 20

σ = 43.7

Let plug in the formula

Confidence interval estimate = 90.7 ± 2.33 (43.7/√20)

Confidence interval estimate= 90.7 ± 22.76786775

Confidence interval estimate=90.7 - 22.76786775 < μ < 90.7 + 22.76786775

Confidence interval estimate= 67.9 min < μ < 113.5 min

Therefore the confidence interval estimate will be 67.9 min < μ < 113.5 min

Answer:

The test value is z = -1.31.

Step-by-step explanation:

The Eagle Ridge Contractors Association claims the average price of a home in their subdivision is $125,150.

This means that the null hypothesis is that the mean is this value, that is:

[tex]H_0: \mu = 125150[/tex]

The Eagle Ridge Home Owners Association is interested in knowing if the costs of homes for sale in this subdivision are actually lower than claimed.

This means that at the alternate hypotehsis we test that the mean is lower than that value, that is:

[tex]H_a: \mu < 125150[/tex]

The test statistic is:

[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, [tex]\sigma[/tex] is the standard deviation and n is the size of the sample.

125150 is tested at the null hypothesis:

This means that [tex]\mu = 125150[/tex]

Standard deviation of $7,350.

This means that [tex]\sigma = 7350[/tex]

A sample of 36 homes for sale in this subdivision had an average selling price of $123,550.

This means that [tex]n = 36, X = 123550[/tex]

Compute the test value.

[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

[tex]z = \frac{123550 - 125150}{\frac{7350}{\sqrt{36}}}[/tex]

[tex]z = -1.31[/tex]

The test value is z = -1.31.

Answer:

• 25%

• Drama movie

Step-by-step explanation:

• Total number of children

= 16 +12 +18 +20 +14

= 80

Percentage of children that voted for action movie

[tex] = \frac{no. \: of \: children \: that \: voted \: for \: action \: movie}{total \: number \: of \: children} \times 100\%[/tex]

[tex] = \frac{20}{80} \times 100\%[/tex]

[tex] =\textbf{25\%}[/tex]

------------------------------------------------------------

• Total number of votes

= 30 +32 +36 +36 +26

= 160

20% of total votes

= 20% ×160

= 32 votes

Since Drama movie received 32 votes, it received 20% of the total votes.

Answer:

a = 0.8

Step-by-step explanation:

a varies jointly as b and c.

This means that a can be written as a constant k multiplied by b multiplied by c, that is:

[tex]a = kbc[/tex]

One set of values is a = 2.4, b = 0.6, and c = 0.8.

We use this to find the value of k:

[tex]2.4 = k(0.8)(0.6)[/tex]

[tex]0.48k = 2.4[/tex]

[tex]k = \frac{2.4}{0.48}[/tex]

[tex]k = 5[/tex]

So

[tex]a = 5bc[/tex]

Find a when b = 0.4 and c = 0.4.

[tex]a = 5bc = 5(0.4)(0.4) = 5(0.16) = 0.80[/tex]

The answer is a = 0.8.

Note how the 3 and 10 are two values such that

We can use the distribution rule like so to help confirm the answer

(x+3)(x+10)

y(x+10) ... replace x+3 with y

xy+10y .... distribute

x( y ) + 10( y )

x( x+3 ) + 10( x+3 ) .... plug in y = x+3

x^2+3x + 10x+30 .... distribute again twice more

x^2 + 13x + 30 ... combine like terms

Answer:

10.3

Step-by-step explanation:

Recall SOH, CAH, TOA

In this case we have the hypotonouse is given (the hyptonouse is the side that is opposite from the right angle) and we need to solve for the opposite

therefore we will use SOH

we have

sin(69)=x/11

11*sin(69)=x

x=10.269

which rounds to

10.3

Answer:

[tex] \displaystyle \: x= 10.3[/tex]

Step-by-step explanation:

we are given hypotenuse and [tex]\theta[/tex]

we want to figure out x (opposite)

remember that,

[tex] \displaystyle \: \sin( \theta) = \frac{opp}{hypo} [/tex]

here our [tex]\theta [/tex] is 69°

and hypo is 11 and opp is x

so substitute:

[tex] \displaystyle \: \sin( 69 ^{ \circ} ) = \frac{ x}{11} [/tex]

cross multiplication:

[tex] \displaystyle \: x= 11 \sin( 69 ^{ \circ} ) [/tex]

by using calculator:

[tex] \displaystyle \: x= 10.3[/tex]

PART A: Two pieces of information that are included by the graph are the minimum value (20)  and the maximum value (95). One piece of information that is not included in the graph is the number of students who surf the internet. (this one doesn't really need a step by step because it is just analyzing a graph)

PART B:  The IQR is equal to 20. The IQR represents the mid-spread, or 50% of the data.

Step-By-Step:

To find the IQR, you need to subtract the first quartile from the third quartile. So to find the IQR we would need to subtract 60 (Q3) and 40 (Q1),

60-40 = 20

= 20.

20 is the IQR

PART C: If an outlier is present, it may affect the mean, but will not change the median or the mode.

Step-By-Step: An outlier is an abnormally large (or small) number in a given data set.

Best of luck,

Some 6th grader.

Answer:

Step-by-step explanation:

The graphs can be seen in the picture attached below where

y= sin x is the red wave

y= sin 2x is the blue wave

y=2 sin x  is the green wave

Each graph is obviously a wave in shape but where they all differentiate is in the frequency and amplitude of the wave. Meaning how often a wave cycle repeats in the functional and how high and low the wave cycles actually get. That is where the difference takes place sinx has wider wave cycles than the other two. sin2x has the shortest wave cycles, almost twice for everyone red wave cycle. While 2sinx has the highest and lowest amplitude of all of the waves.

Answer:

y = 2/3x - 2

Step-by-step explanation:

If two lines are parallel to each other, they have the same slope.

The first line is y = 2/3x + 1. Its slope is 2/3. A line parallel to this one will also have a slope of 2/3.

Plug this value (2/3) into your standard point-slope equation of y = mx + b.

y = 2/3x + b

To find b, we want to plug in a value that we know is on this line: in this case, it is (3, 0). Plug in the x and y values into the x and y of the standard equation.

0 = 2/3(3) + b

To find b, multiply the slope and the input of x (3)

0 = 2 + b

Now, subtract 2 from both sides to isolate b.

-2 = b

Plug this into your standard equation.

y = 2/3x - 2

This equation is parallel to your given equation (y = 2/3x + 1) and contains point (3, 0)

Hope this helps!
