Step-by-step explanation:

Tell me if I'm wrong but 100% sure I'm right

Answer 2

The linear regression for the best fit of the data to identify the runner that kept the most consistent pace is Runner C

What is linear regression line?

The connection between the independent (x) and dependent (y) variables in the graph can be graphically represented using regression lines.

In a linear model, the terms are added rather than multiplied, divided, or provided as a non-algebraic function, as has been the case thus far in this section. Analysis of experimental, monetary, and biological data as well as complex system prediction are both possible using linear modelling.

A statistical technique used to build a linear model is called linear regression. The model explains how one or more independent variables Xi relate to a dependent variable y (also known as the response) (called the predictors). The distance between each data point and the regression line is called a residual.

Given data ,

Three runners competed in a race data were collected at each mile mark for each runner

And , If the runner ran at a constant paste the data would be linear

Now , a linear a regression line was fitted to their data

And , In linear regression, consistent data refers to a set of data points that fall in a linear pattern with a small amount of scatter around the line of best fit. The data is said to be consistent if the residuals (the vertical distances between the observed data points and the predicted values on the line of best fit) are relatively small and do not exhibit any patterns or trends.

So , the runner C has the most consistent pace among the three runners

Hence , runner C is the best fit for the regression line

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.

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

Using Cramer’s Rule, what is the value of x in the solution to the system of linear equations below?
2/5X + 1/4Y = 9/20
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

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.

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:

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.

The sum of two numbers is 9. If one number is subtracted from the other, the difference is −3. Find the two numbers.

Answers

Answer:

The numbers are 6 and 3

Step-by-step explanation:

Let the numbers be x and y

So their sum is x + y =9 (EQ. 1)

Their difference is x - y = -3 (EQ. 2)

Solve simultaneously using subtract method.

x-x=0, x is eliminated. y- -y = +2y since -x- is +.

so it is now 2y = 9- - 3:. 2y= 12; dividing both sides by 2. Y=6.

Substitute Y=6 in EQ 1 to find x.

So x + 6=9;. x=9-6 is achieved by collecting like terms. so x=3.

:. Y=6 and x=3. The numbers are 6 and 3
