Using the given scatter plot, let's describe the relationship between the average income in a city and the average rent for a 1-bedroom apartment in that city.

Here, the average income is represented on the x-axis while the average rent is represented on the y-axis.

Using the scatter plot, we can see that as the average income increases, the average rent also increases.

Since one variable increase as the other increases, and the points show a straight line pattern, we can say the relationship between them is a positive linear association.

Therefore, the relationship between the average income and the average rent for a 1-bedroom apartment in that city is a positive linear association.

======================================

Explanation:

Your diagram is 100% correct. Nice work.

To get the area of the trapezoid, we could use the area of a trapezoid formula below:

A = h*(b1+b2)/2

In this case, we have,

the bases are parallel to each other. The height is always perpendicular to the base. We won't use the "14" at all.

So,

A = h*(b1+b2)/2

A = 7*sqrt(3)*(18+25)/2

A = 7*sqrt(3)*21.5

A = (7*21.5)*sqrt(3)

A = 150.5*sqrt(3)

This is the exact area.

The approximate area is roughly

150.5*sqrt(3) = 260.673646539

The units for the area are in square km, or km^2. Though your teacher said for you not to include the units.

Another way to get the area of the trapezoid is to break the diagram into a rectangle and triangle as you have done so, and then find the area of each sub-piece. Adding the two smaller areas should lead to the result shown above.

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

To get the perimeter, we add up all of the exterior sides. We do not include the right-most vertical line that is 7*sqrt(3) km long because it is inside the figure. The horizontal segment that is 7 km long is part of the "25 km" segment, so we'll ignore that 7.

Adding the four exterior sides leads to:

7*sqrt(3)+18+14+25 = 57+7*sqrt(3)

This value is exact. It approximates to

57+7*sqrt(3) = 69.12435565

The units for the perimeter are in kilometers, and you won't have any exponent over the "km". While your teacher doesn't want the units, it's still handy to know what the units would be.

Step-by-step explanation:

solution given:

for rectangle

length [l]=18km

breadth [b]=7√3 km

for triangle

base[b1]=25-18=7km

height [h]=b=7√3km

for area :area of. (rectangle +triangle}=

l×b+1/2 b1×h=18×7√3+1/2 ×7×7√3=260.67km²

now

perimeter=sum of all sides

=18+14+25+7√3=69.12km

Answer:

A). Using dependent samples with paired data is generally better than using two independent samples.

Explanation:

Observational studies is the research/study design in which the investigator observes the samples collected from the population in their natural pattern to make valid inferences without any kind of manipulation or interference. While the experimental studies involves a controlled or manipulated variable in order to check its impact over the independent variable and the relation between the two.

As per the question, the design principle that is emphasized for both the studies would be 'employing dependent samples along with the paired data is usually effective than employing two independent samples' as the former concerns one set of elements that makes them 'self-evident'(as the subjects of one sample can be employed to determine the subjects of other). Thus, option A is the correct answer.

Answer:

its just 22

Step-by-step explanation:

To find the value of x, we can set the two angle measures equal to each other and solve for x.

Given:

mZA = (4x - 2)°

mZB = (6x - 20)°

Setting them equal to each other:

4x - 2 = 6x - 20

Now, we can solve for x:

4x - 6x = -20 + 2

-2x = -18

Dividing both sides by -2:

x = -18 / -2

x = 9

Therefore, the value of x is 9.

Answer:

The answer is 9.

Step-by-step explanation:

We need to use the fact that the sum of the angles in a triangle is 180 degrees. Let A, B, and C be the three angles in the triangle. Then we have:

mZA + mZB + mZC = 180°

Substituting the given values, we get:

(4x - 2)° + (6x - 20)° + mZC = 180°

Simplifying the left side, we get:

10x - 22 + mZC = 180°

Next, we use the fact that angles opposite congruent sides of a triangle are congruent. Since we know that segment AC and segment BC are congruent, we have:

mZA = mZB

Substituting the given values and simplifying, we get

4x - 2 = 6x - 20

Solving for x, we get:

x = 9

Therefore, the value of x is 9.

2 3/4 degree below Zero = less than 0 = - 2 3/4

-3 ; - 2 3/4 ; + 5 ; + 6

Step-by-step explanation:

5 degrees above Zero = greater than 0 = + 5

3 degrees below Zero = less than 0 = - 3

6 degrees above Zero = greater Than 0 = + 6

2 3/4 degree below Zero = less than 0 = - 2 3/4

Answer:

Step-by-step explanation:

The amount (A) resulting from principal P invested at simple interest rate r for t years is ...

  A = P(1 +rt)

  A = $100,000(1 +0.05·4) = $120,000

__

The amount resulting from interest being compounded daily is ...

  A = P(1 +r/360)^(365.25t)

  A = $100,000(1.00013888...)^1461 = $122,495.31

The "Banker's rule" says the daily rate is based on 360 days per year. The actual interest is computed based on the exact number of days. In 4 years, there will be a leap year, so that's 1461 days.

__

The investment with compounded interest earns more.

  $122,495.31 -120,000.00 = $2,495.31

The difference in interest earned is $2,495.31.

From the sampling distribution, the correct answer is: Both the center will remain the same, but the spread will decrease.

The center of the sampling distribution will remain the same, which is the expected proportion of even numbers showing on a single roll of the die, which is 1/2 or 0.5. This is because the probability of getting an even number on a single roll of the die does not change with the number of rolls in the experiment.

However, the spread of the sampling distribution will decrease as the number of rolls increases. This is because the larger the sample size, the more precise our estimate of the proportion of even numbers showing on each roll of the die will be. With more rolls, we will have a better idea of the true proportion of even numbers that the die produces.

Using the concept of proportions and ratios on the similar triangles, the value of x is 48 units

Similar triangles are triangles that have the same shape but may differ in size. They have corresponding angles that are equal and corresponding sides that are proportional. In other words, the ratios of the corresponding sides of similar triangles are equal.

The concept of similar triangles is based on the fundamental property that corresponding angles in similar shapes are equal, and the corresponding sides are proportional.

To determine the value of x, we can apply the concept of proportions and ratio on the similar triangle;

x / 36 = 64 / x

Cross multiplying both sides

x * x = 36 * 64

x² = 2304

x  = √2304

Answer:

cos60°

Step-by-step explanation:

Using the cofunction identity

cos(90 - x) = sinx , then

sin30° = cos(90 - 30)° = cos60°

The value of the trigonometric equation is sin ( 30 )° = cos ( 60 )°

Trigonometry is the study of the connections between triangle angles and side lengths.

The trigonometric relations are represented as sin , cos , tan , cosec , sec and cot

Let the angle be θ , such that

sin θ = opposite / hypotenuse

cos θ = adjacent / hypotenuse

tan θ = opposite / adjacent

tan θ = sin θ / cos θ

cosec θ = 1/sin θ

sec θ = 1/cos θ

cot θ = 1/tan θ

Given data ,

Let's call the trigonometric relationship A.

Now , the value of A is

sin ( 30 ) = 1/2

Now , the value of cos ( θ ) which gives the value of 1/2 is given by

when θ = π/3 or θ = 60°

cos ( 60 )° = 1/2

Therefore , the trigonometric relation is cos ( 60 )° = 1/2

Hence , the equation is sin ( 30 )° = cos ( 60 )°

Hence the answer is 60 square units

The user in Atlanta around 3 seconds to download the web page and pictures from the web server in Denver.

Based on the given information, we can calculate the total time it would take for the user in Atlanta to retrieve the web page and the images from the web server in Denver, assuming a round-trip time (RTT) of 50 ms and a bandwidth of 2 Mbps.

First, we need to convert the file sizes to bits:

Web page: 25 Kbytes = 200 kbits

Each image: 200 Kbytes = 1600 kbits (3 images in total)

Next, we can calculate the time it would take to transfer the web page:

Time to transfer web page = (200 kbits) / (2 Mbps) = 0.1 seconds

Consider it the time it takes for the request and response to travel back and forth between the user in Atlanta and the web server in Denver.

Since the RTT is 50 ms, this round trip time would be 100 ms (50 ms for the request and 50 ms for the response).

Therefore, the total time to transfer the web page would be:

Total time for web page

= 0.1 seconds + 0.1 seconds + 0.05 seconds

= 0.25 seconds

Next, we can calculate the time it would take to transfer all three images:

Time to transfer one image = (1600 kbits) / (2 Mbps) = 0.8 seconds

Total time to transfer three images = 3 x 0.8 seconds = 2.4 seconds

Again, we need to consider the time for the request and response to travel back and forth, which would be a total of 100 ms for each image. Therefore, the total time to transfer all three images would be:

Total time for images

= 2.4 seconds + 3 x 0.1 seconds + 3 x 0.05 seconds

= 2.75 seconds

Adding the time for the web page and the images, the total time to retrieve the web page and images would be:

Total time = 0.25 seconds + 2.75 seconds = 3 seconds

Therefore, it would take the user in Atlanta approximately 3 seconds to retrieve the web page and images from the web server in Denver, given the assumptions and parameters provided.
