In 2002, the average price of a new domestic car was $19,126. In 2008, the average price was $28,715. Based on a linear model, what is the predicted average price for 2014? Ston Down​

Answers

Answer:

The predicted average price for 2014 is of $38,304.

Step-by-step explanation:

Linear model:

In a linear model, the average price increases by the same amount during each period.

In 2002, the average price of a new domestic car was $19,126. In 2008, the average price was $28,715.

In a period of 6 years, the increase was of:

28715 - 19126 = $9,589

Based on a linear model, what is the predicted average price for 2014?

Another period of 6 years, so it will increase by 9589 more. Than

28715 + 9589 = 38304

The predicted average price for 2014 is of $38,304.

Answers

Answer:

If I did my math correctly, I'm pretty sure the answer is 3 1/36 yards.

Step-by-step explanation:

1. First, you have to turn them all into an improper fraction.

1 7/18 becomes 25/18

1 2/9 becomes 11/9

5/12 remains the same as it's already an improper fraction.

2. Find a common denominator, which is 36

25/18 becomes 50/36

11/9 becomes 44/36

5/12 becomes 15/36

3. Add them all together and you get 109/36

4. Turn it into a mixed number, and in this case, is 3 1/36

Solution is 3 1/36

Invent measurements that would show triangle XYZ is similar to triangle NLM using the Side-Angle-Side Triangle Similarity Theorem.

Answers

Answer:

The answer is that when you put the LMN. You can rotate it. Then we know it is similar.

Using the rotation method of the triangle LMN show triangle XYZ is similar to triangle NLM using the Side-Angle-Side Triangle Similarity Theorem.

What is the similarity law for triangles?

It is necessary to demonstrate compliance with the law to establish that two triangles are identical in both shape and size. The angles that correspond to those sides have the same congruence and the same ratio of sides.

It is given that the two triangles are triangle XYZ and triangle NLM.

Two triangles are said to be comparable if the ratio of one triangle's two sides to the two sides of another triangle is the same, and the angles that the two sides of both triangles inscribe are equal.

Thus, triangle XYZ is similar to triangle NLM using the Side-Angle-Side Triangle Similarity Theorem.

Hal and Renee take turns drawing a tile, recording the letter, and placing the tile back in the bag. Renee earns a point if she draws a vowel. Hal earns a point if he draws a consonant. They decide that the letter y can be a vowel or a consonant. Which statement best explains whether or not the game is fair?

A) The game is fair because both Hal and Renee will get a point if the letter y is drawn.

B) The game is not fair because the probability of Hal drawing a winning letter is more than the probability of Renee drawing a winning letter.

C) The game is fair because Hal and Renee have the same probability of drawing a winning letter.

D) The game is not fair because the probability of Hal drawing a winning letter is less than the probability of Renee drawing a winning letter.

(SOMEONE PLEASE HELP ME)

Answers

Answer:

B

Step-by-step explanation:

There are more consonants in the phrase than vowels so Hal has a better chance of pulling a winning letter. Also, before any tiles have been drawn, Hal has a 9/14 chance of pulling a winning tile while Renee has a 5/14 chance.

Option B is correct.

As given the bag has 14 tiles, each with a letter from the phrase the probability on it.

What is probability?

Probability is nothing but the ratio of number of favorable outcome and total number of outcomes.

Now,

As we know a phrase always consist of vowels and consonants and the number of consonants is always greater than vowels.

Therefore, Hal has better chance of pulling a willing letter. Also before any tiles have been drawn, so Hal has a 9/14 chance of pulling a winning tile while Renee has a 5/14 chance.

Hence, option B is the correct option.

Using Cramer’s Rule, what is the value of x in the solution to the system of linear equations below?

2/3X + 5/12 = 3/4

A)X = 0
B)X = 1
C)There are no solutions to the system.
D)There are infinite solutions to the system.

Answers

Using Cramer’s Rule, the value of x is 0

How to determine the value of x?

We have:

2/5X + 1/4Y = 9/20

2/3X + 5/12 = 3/4

Represent as a matrix

[tex]\left[\begin{array}{cc}2/5&1/4\\2/3&5/12\end{array}\right] \left[\begin{array}{c}9/20&3/4\end{array}\right][/tex]

Start by calculating the determinant of the matrix

A = 2/4 * 5/12 - 2/3 * 1/4

Evaluate the product

A = 5/24 - 1/6

Evaluate the difference

A = (5 - 4)/24

|A| = 1/24

Next, replace the last column with the first

[tex]\left[\begin{array}{cc}9/20&1/4\\3/4&5/12\end{array}\right][/tex]

Calculate the determinant

|x| = 9/20 * 5/12 - 1/4 * 3/4

Evaluate the product

|x| = 3/16 - 3/16

Evaluate the difference

|x| = 0

The value of x is then calculated as:

x = |x|/|A|

So, we have:

x = 0/(1/24)

Evaluate

x = 0

Hence, the value of x is 0

Second term of a geometric series is , the limiting sum is 9.
Get the values of first term a and common ratio r.

Answers

Answer:

The answer is below

Step-by-step explanation:

Second term of a geometric series is 2, the limiting sum is 9.

Get the values of first term a and common ratio r.

Solution:

A geometric series is in the form:

a + ar + ar² + ar³ + . . . + arⁿ ⁻ ¹

Where a is the first term, n is the nth term and r is the second ratio.

Since the second term of the series is 2, hence:

ar⁽² ⁻ ¹⁾ = 2

ar = 2        (1)

Also, the limiting sum is 9, hence:

a/ (1 - r) = 9

a = 9 - 9r     (2)

Substitute a = 9 - 9r in eqn 1:

(9 - 9r)r = 2

9r - 9r² = 2

9r² - 9r + 2 = 0

9r² - 6r - 3r + 2 = 0

3r(3r - 2) -1(3r - 2) = 0

(3r - 1)(3r - 2) = 0

r = 1/3 or r = 2/3

When r = 1/3; a = 9 - 9r = 9 - 9(1/3) = 6

When r = 2/3; a = 9 - 9r = 9 - 9(2/3) =  3
