B. No, because the Central Limit Theorem states that the sampling distribution of x is approximately normally distributed only if the sample size is large enough.

The Central Limit Theorem (CLT) is a fundamental concept in statistics that states that as the sample size increases, the sampling distribution of the sample means will approach a normal distribution. However, this is only true if certain conditions are met, one of which is having a large enough sample size.
The CLT states that the sampling distribution of x will be approximately normally distributed if the sample size is large enough (usually greater than 30). If the sample size is small, the sampling distribution may not be normally distributed. In such cases, other statistical techniques like the t-distribution should be used.
Furthermore, the CLT assumes that the population being sampled is not necessarily normally distributed, but it does require that the population has a finite variance. This means that even if the population is not normally distributed, the sampling distribution of x will still be approximately normal if the sample size is large enough.
In conclusion, the answer is B, as the Central Limit Theorem states that the sampling distribution of x is approximately normally distributed only if the sample size is large enough.

The use of intersecting lines in a drawing to indicate areas of shadow and depth is called "cross-hatching."

Cross-hatching is a technique used in drawing and other visual arts to create the illusion of shadows, volume, and depth. It involves drawing a series of intersecting parallel lines or strokes in close proximity to one another. By varying the density, spacing, and direction of these lines, an artist can create areas of darker shading or indicate the contours and three-dimensional form of an object.

The intersecting lines create a pattern that visually simulates the effect of shadows and adds dimensionality to the artwork. Cross-hatching is a versatile and effective method to enhance the realism and visual impact of a drawing, and it is commonly employed in various art forms such as sketching, illustration, and pen-and-ink techniques.

Answer: GP = ar^n-1

To find r , divide the 2nd term by the 1st term or the 3rd term by the 2nd term.
Now r = 3/4 or g/3. To find g now, the two can be equated together and solve for g or by multiplying the 2nd term by the common ratio.
(1) r = 3/4 ……………………,(1)

r =. g/3……………………..(2)

g = 3/4 x 3

= 9/4. or

3/4 = g/4, by cross multiplying the equation, it now becomes

4g = 3 x3

4g = 9

Now divide both dude by the coefficient of g which is 4

g = 9/4

Now, r = 3/4 or g/3 and g = 9/4

Step-by-step explanation:

Area = 1/2 * base * height

         = 1/2 * 8 * 5.2

Answer:

A = 20.8 cm²

Step-by-step explanation:

We have just to use the following expression:

A = (Base x height) / 2

So:

A = (8 x 5.2) / 2

A = 4 x 5,2

A = 20.8 cm²

Answer:

y=1/3x+0 or y=1/3x

Step-by-step explanation:

find the slope by taking two points and putting them in

y2 - y1/x2 - x1

so, (3,1) and (6,2) becomes 2-1/6-3 or 1/3 so, slope is 1/3

then to find y intercept you can put a point (6,2) and slope (1/3) into slope intercept form y - y1 = m(x - x1)

y - 2 = 1/3(x-6)

when you solve this you get y = 1/3x + 0, so y intercept is 0. you can also see. this on the graph given

The calculated value of the expression x² + y² + 8 is 12 - 2xy

From the question, we have the following parameters that can be used in our computation:

x + y + 2 = 0

This can be expressed as

x + y = -2

Using the sum of two squares, we have

x² + y² = (x + y)² - 2xy

So, we have

x² + y² = (-2)² - 2xy

Evaluate

x² + y² = 4 - 2xy

Add 8 to both sides

x² + y² + 8 = 12 - 2xy

Hence, the value of the expression x² + y² + 8 is 12 - 2xy

Answer:

96/x

Step-by-step explanation:

When two variables x and y vary inversely, their product is a constant. Therefore, the function that models the inverse variation between x and y is:

x*y = k

where k is the constant of proportionality.

We can use the given information to find the value of k:

x = 12 when y = 8

so, k = xy = 128 = 96

Now we can use this value of k to write the function that models the inverse variation:

x*y = 96

To find the inverse variation, we divide both sides by y,

x = 96/y

Alternatively, we can write y = 96/x

So, the function that models the inverse variation between x and y is either x = 96/y or y = 96/x

Based on proportions, the numbers of students in the senior form and junior form are 615 and 885, respectively.

Proportion refers to the equation of two ratios.

Proportion is a fractional value depicted using ratios, percentages, fractions, and decimals.

The percentage of senior form students in the school = 41%

The percentage of junior form students = 59% (100% - 41%)

The additional percentage of junior over senior students = 18% (59% - 41%)

The additional number of junior form students over the seniors = 270

Proportionately, if 18% = 270, the total number of students (both junior and senior) = 1,500.

Therefore, the number of senior and junior students is as follows:

Check:

The difference in the numbers = 270 (885 - 615)

Thus, using proportions, we can state that there are 1,500 students in the school, consisting of 615 seniors and 885 juniors.

The inequality form of the given expression is:

x < -8 or x > 0

The interval notation is : (−∞,−8)∪(0,∞)

Given, the expression is |x + 4| - 4 > 0

An inequality is a relationship that shows a non-equal comparison between two numbers or mathematical expressions.

Isolate the variable by dividing each side by factors that don't contain the variable.

⇒  |x + 4| - 4 > 0

⇒  |x + 4|  > -4

Remove mod.

⇒ x + 4 > -4 or  x - 4 > -4

⇒ x > -4 -4 or x > -4 +4

⇒ x <-8 or x > 0

Hence the internal notation is :

Step-by-step explanation:

The minutes that it would take for the 0702 bus to go from Birmingham to Coventry is 92 minutes.

The latest time that Steve should leave his house so as to get to work on time is 07 56 hours .

If the bus from Birmingham leaves at 07 02 hours, it would reach Coventry at 08 34. The time taken is therefore :

= 08 34 - 07 02

= 1 hour 32 minutes

In minutes, this is:

= 60 minutes in an hour + 32

= 92 minutes

The total time it would take Steve to reach Coventry from Birmingham would be:

= Time to Coventry + Time spent walking from house + Time spent walking in Coventry

= 92 minutes + 9 + 12

= 113 minutes

The time Steve should leave his house at the latest is:

= 10 am - 113 minutes

= 08 07 hours

However, he would miss the 08 35 bus if he did this so he needs to leave in time for the 08 05 bus which is:

= 08 05 - 9 minutes walking

= 07 56 hours

The following formula may be used to calculate the measure of an angle: angle measurement = (intercepted arc size of angle) / (360 degrees)

Where the size of the intercepted arc of the angle equals the radius of the circle produced by the angle.

If we know the ratio of the sides of a triangle, we may use trigonometry to get the measure of an angle.

The sine of an angle, for example, is the ratio of the length of the side opposite the angle to the length of the hypotenuse. The cosine of an angle is the ratio of the length of the adjacent side to the length of the hypotenuse, and the tangent of an angle is the ratio of the length of the hypotenuse to the length of the adjacent side.

As a result, we might use sin(theta)=opposite/hypotenuse.

cos(theta)=adjacent/hypotenuse

tan(theta)=opposite/adjacent

It is important to carefully select the survey population and explain why the survey is necessary. It is also important to limit the number of questions and ask them in a clear and concise manner.

Select the survey population carefully: This means selecting a group of people who are representative of the target population and have the relevant knowledge or experience to answer the survey questions. For example, if the survey is about customer satisfaction with a product, the survey population should be customers who have used the product.

Limit the number of questions: It's important to keep the survey short and focused to reduce the risk of respondent fatigue and increase the response rate. A shorter survey also makes it easier to analyze the data.

Explain why the survey is necessary: This helps to increase the response rate by providing a clear explanation of why the survey is being conducted, what the data will be used for, and how it will benefit the target population.

Select the survey population randomly: Random selection helps to ensure that the survey results are representative of the target population and minimize the risk of bias in the sample.

     See the attached image for my work. First, you need to know the quadrants. In order from the top right counter-clockwise, it goes I (1), II (2), III (3), and IV (4).

     Next, we will count up five units since Quadrant II is above the point, in Quadrant III.

The value of unknown variable x and y for the attached similar polygon is equal to 24 and 7 respectively.

Polygon with side measure are as follow,

In the attached figure,

Let the name of the small triangle be ABC.

AB = y

BC = 25

CA = x

And the name of the larger triangle be ADE

AD = 14

DE = 50

AE = 48

Both the polygons are similar to each other.

Corresponding sides of similar polygon are in proportion.

ABC ↔ ADE

AB / AD = AC / AE = BC/ DE

This implies,

y/ 14 = 25/ 50 = x / 48

Now solve for x we have,

25/ 50 = x / 48

⇒ x = ( 1/ 2 ) × 48

⇒ x = 24

Now solve for y we have,

y/ 14 = 25/ 50

⇒ y = ( 1/ 2) × 14

⇒ y = 7

Therefore, the value of x and y for the similar polygon is equal to 24 and 7 respectively.
