Total Price for her vehicle will be $20600

Step-by-step explanation:

Edith's trading is worth $8000. So, without the package upgrade of the vehicle delivery charge, her cost is:

$22750 - $8000 = $14750.

Now, add the package upgrade ($5050) and the delivery charge ($800).

$14750 + $5050 + $800 = $20600.

The total cost price of the vehicle after all the expenses is given by the equation A = $ 20,500

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

The initial cost of the vehicle is = $ 22,750

Now , Edith has asked for an upgrade to a premium package for which the cost is $5050

So , the new cost of the vehicle = $ 22,750 + $ 5050 = $ 27,800

Now , the delivery charge of the vehicle = $ 700

And , the updated total price = $ 27,800 + $ 700 = $ 28,500

Now , the dealer has offered her $8000

So , the final price of the vehicle = updated total price - $ 8000

On simplifying the equation , we get

The final price of the vehicle A = $ 28,500 - $ 8,000

The final price of the vehicle A = $ 20,500

Hence , the final price of the vehicle is $ 20,500

Answer:

Mean, median and mode are measures of central tendency. The median is a better measure of central tendency when the given data contains outliers.

Step-by-step explanation:

Mean, median and mode are all measures of central tendency. These are statistical information that gives the middle or centre of a set of data. Since the values are central, they usually represent the entire distribution.

The mean is the obtained by dividing the sum of all the scores by the number of scores. The median is the middle value when numbers are arranged in increasing or decreasing order of magnitude. The mode is the most frequently occurring score in a distribution.

Let us see an example of the median as a measure of central tendency. Given the set of values; 4, 10, 12, and 26, the median is obtained from the average of the two middle numbers in the set of values which are 10 and 12 as seen from the set of values above. Hence the median of this set of values is 11.

The median can be a very good measure of central tendency, even better than the mean mostly in situations where there are outliers, or extreme values.

Answer:

1/100

Step-by-step explanation:

Since the numerators are all the same, the lowest value will depend on the denominators. The greater the denominator, the lower the value. Thus, the answer is 1/100

Answer:

15 cm

Step-by-step explanation:

Median means middle number

10,15,15,18,20

Answer:

15 cm

Step-by-step explanation:

The median is the number in the middle of a data set.

First, arrange the data from least to greatest.

10 cm, 15 cm, 15 cm, 18 cm, 20 cm

Now, take one number off each end of the data set until the middle number is reached.

10 cm, 15 cm, 15 cm, 18 cm, 20 cm

15 cm, 15 cm, 18 cm

15 cm

Therefore the median of the set of measurements is 15 cm.

The scale factor of the two triangles is [tex]\frac{3}{4}[/tex].

When two triangles are similar, the reduced ratio of any corresponding sides is called  the scale factor of the similar triangles.

Similar triangles are triangles that have the same shape, but their sizes may vary.

According to the given question

We have two triangles NGK and ALH

In which

NG = 15, GK = 6, NK = 3

And, AL =  20, LH = 8 and AH = 4

Since, we have to find the scale factor of these two triangles so the two triangles must be similar.

As, ΔNGK is similar to ΔALH

⇒ [tex]\frac{NG}{AL} = \frac{GK}{LH} = \frac{NK}{AH}[/tex]

⇒ [tex]\frac{15}{20} = \frac{6}{8} =\frac{3}{4}[/tex]

⇒ [tex]\frac{3}{4} = \frac{3}{4} =\frac{3}{4}[/tex]

Hence, the scale factor of the two triangles is [tex]\frac{3}{4}[/tex].

Answer:

126

Step-by-step explanation:

We multiply 42 × 3= 126

The measure of the angle is 126.

The measure of angle will be 66°.

What is Complementary angle?

The sum of two or more angle is 90 degree then the angle is called the complementary angle.

Given that;

The measure of the supplement of an angle is 42 more than 3 times the measure of the complement of an angle.

Now,

Let the measure of angle = x

So, We can formulate;

⇒ (180 - x) = 42 + 3 (90 - x)

Solve for x as;

⇒ 180 - x = 42 + 270 - 3x

⇒ 180 - x + 3x = 312

⇒ 2x = 312 - 180

⇒ 2x = 132

⇒ x = 66

Thus, The measure of angle will be 66°.

A. Tomas is correct; AC is opposite ∠B and BC is adjacent to ∠B.

Step-by-step explanation:

edge2021

The description of Thomas is correct. AC is opposite ∠B and BC is adjacent to ∠B.

Right angled triangle are those triangle for which one of the angle is 90 degrees.

Hypotenuse of a right angled triangle is the longest side.

Opposite side with respect to an angle is the side opposite to that angle.

Adjacent side with respect to an angle is the side which is adjacent to the angle.

Given is a triangle ABC.

Here C is the right angle.

Then the side opposite to the right angle is the hypotenuse.

So AB is the hypotenuse.

Now we are describing the sides in relation to the ∠B.

Side opposite to ∠B is AC, which is the opposite side.

Side adjacent to ∠B is BC, which is the adjacent side.

This is the description of Thomas.

Hence Thomas is correct about describing the sides in relation to ∠B.

Answer:

The value of the test statistic is:

t = -1.112

Step-by-step explanation:

In this case a paired difference test is to be performed.

The hypothesis can be defined as follows:

H₀: There is no difference between the two population means, i.e. d = 0.

Hₐ: There is a significant difference between the two population means, i.e. d ≠ 0.

The significance level of the test is, α = 0.10.

Use MS-Excel to perform the analysis.

Consider the output attached below.

The value of the test statistic is:

t = -1.112

The p-value of the two-tailed test is:

p-value = 0.303.

Decision rule:

Reject the null hypothesis if the p-value is less than the significance level.

p-value = 0.303 > α = 0.10.

The null hypothesis was failed to be rejected at 10% level of significance.

Conclusion:

There is not enough evidence to support the claim that there is a difference between the two population means.

Answer:

Step-by-step explanation:

Let the volume of tank be x

In 18 hours volume of tank filled = x

we have to find the volume of tank which is filled in 1 hours.

For that we divide LHS and RHS by 18

In 18/18 hours volume of tank filled = x/18

In 1 hours volume of tank filled = x/18

In 30 hours volume of tank emptied = x

we have to find the volume of tank which is emptied in 1 hours.

For that we divide LHS and RHS by 30

in 30/30 hours volume of tank filled = x/30

In 1 hours volume of tank filled = x/30

If tank is empty and one starts to fill it, two things will happen

it will start filling at rate of x/18 hours

But there is leak which will start to empty the tank at  x/30 hours

So , at any given time rate if filling of water will be rate of filling the tank- rate of emptying the tank

In 1 hour volume of tank filled if both filling and leaking takes place simultaneously =  x/18 -x/30 = (30-18)x/18*30 = 12x/18*30 = x/3*15 = x/45

In 1 hour volume of tank filled = x/45

in 1*45 hour volume of tank filled = x/45*45 = x

Thus, it will take 45 hours to fill the leaky tank  .

[tex]solution \\ {2x}^{2} - x + ( - x - {2x}^{2} - 2) \\ = {2x}^{2} - x - x - {2x}^{2} - 2 \\ = {2x}^{2} - {2x}^{2} - x - x - 2 \\ = - 2x - 2[/tex]

I believe consumers and targets of these ad campaigns should know EXACTLY what they are buying. They need to be intrigued by the ad without the use of Subliminal Messages because with these tricks, big companies can trick and manipulate people and consumers into buying many things. For example they can buy fast food, sweets, and perhaps medicines that don't even work.

I think the target audience for these advertisements, the buyers, should be completely aware of what they are purchasing. Without the usage of subliminal messages, they must be captivated by the advertisement, since large corporations can deceive and trick individuals into buying a variety of products by using these techniques. They may choose to purchase fast meals, treats, and possibly even ineffective medications.

The process and methods used in advertising are intended to draw attention to a good or service. With the help of advertising, businesses strive to draw consumers' attention to their goods and services. Although there are many purposes, the commercial advertisement is the most frequent. It is typically used to market a certain commodity or service.

Through "branding," in which consumers link a brand names or image with specific traits, commercial advertising frequently aim to boost consumption of their goods or services.
