Answer:

\(y=-8x+80\)

Step-by-step explanation:

\(Slope=\frac{y_2-y_1}{x_2-x_1}=\frac{32-64}{6-2}=\frac{-32}{4}=-8\)

\(y=mx+b\)

\(y=-8x+b\)

\(64=-8(2)+b\)

\(64=-16+b\)

\(80=b\)

Therefore, the estimated line of best fit is \(y=-8x+80\)

Nonverbal instruments have been developed primarily in an attempt to d. assess issues that individuals cannot verbalize.

The answer is d. Nonverbal instruments have been developed primarily to assess issues that individuals cannot verbalize. These instruments are often used in psychology and educational assessments to measure skills and abilities in areas such as mathematics, language, and pre-reading skills, while controlling for the influences of language and culture. Nonverbal instruments can be particularly useful for individuals who struggle with verbal communication or have language barriers.

The exchange of information between people without the use of spoken or written language is referred to as nonverbal communication. Facial expressions, eye contact, gestures, posture, body movements, tone of voice, and even the use of time and space are all included in this broad category of behaviors.

A lot of information about a person's emotional state, intentions, attitudes, and personality traits can be communicated nonverbally. A person's posture and body language, for instance, might show whether they are feeling confident or uneasy, and their tone of voice and facial expressions can show whether they are happy, angry, or sad.

A crucial component of human contact is nonverbal communication since it can improve our ability to understand others, establish rapport, and communicate.

Therefore, the solution of the system is:

x1 = (4569 - 129t)/522

x2 = (161/261)t - (172/261)

x3 = t

The system of equations is:

2x1 + 9x2 + 2x3 = 25              

(1)

6x1 + 28x2 + 85x3 = 77        

(2)

First, let's eliminate the coefficient 6 of x1 in the second equation. We multiply the first equation by 3 to get 6x1, and then subtract it from the second equation.

2x1 + 9x2 + 2x3 = 25 (1) -6(2x1 + 9x2 + 2x3 = 25 (1))        

(3) gives:

2x1 + 9x2 + 2x3 = 25              (1)-10x2 - 55x3 = -73                   (3)

Next, eliminate the coefficient -10 of x2 in equation (3) by multiplying equation (1) by 10/9, and then subtracting it from (3).2x1 + 9x2 + 2x3 = 25             (1)-(20/9)x1 - 20x2 - (20/9)x3 = -250/9  (4) gives:2x1 + 9x2 + 2x3 = 25               (1)29x2 + (161/9)x3 = 172/9          (4)

The last equation can be written as follows:

29x2 = (161/9)x3 - 172/9orx2 = (161/261)x3 - (172/261)Let x3 = t. Then we have:

x2 = (161/261)t - (172/261)

Now, let's substitute the expression for x2 into equation (1) and solve for x1:

2x1 + 9[(161/261)t - (172/261)] + 2t = 25

Multiplying by 261 to clear denominators and simplifying, we obtain:

522x1 + 129t = 4569

or

x1 = (4569 - 129t)/522

The graph of the linear equation y = (1/4)*x - 1 is on the image at the end.

To graph the line, we need to find two points that belong to the line, and then we can connect them with a line.

So let's evaluate the linear equation.

if x = 0

y = (1/4)*0 - 1 = -1

We have the point (0, -1)

Now let's get another point:

if x = 4

y = (1/4)*4 - 1 = 4 - 1 = 3

We have the point (4, 3)

Now graph these two points and draw a line that connects them.

Answer:

Fraction of saving = 1/8

Step-by-step explanation:

Given:

Spent on bills = 3/8

Spend on food = 2/5

Spend on entertainment = 1/10

Find:

Fraction of saving

Computation:

Fraction of saving = 1 - Spent on bills - Spend on food - Spend on entertainment

Fraction of saving = 1 - 3/8 - 2/5 - 1/10

By taking LCM

Fraction of saving = [40 - 15 - 16 - 4]/40

Fraction of saving = [5]/40

Fraction of saving = 1/8

The probability that the team will have exactly 8 turnovers during a game is approximately 0.035 or 3.5%.

Given that the number of turnovers per game follows the Poisson distribution and the team averaged 18 turnovers per game, we can use the Poisson distribution formula to find the probability of the team having exactly 8 turnovers during a game.

The Poisson distribution formula is: P(X = x) = (e^-λ * λ^x) / x!, where λ is the average number of turnovers per game and x is the number of turnovers we want to find the probability for.

a. Using the given information, we have: λ = 18 and x = 8.

Plugging these values into the formula, we get:

P(X = 8) = (e^-18 * 18^8) / 8!

Using a calculator, we can simplify this to:

P(X = 8) ≈ 0.035

The measure of reliability of a statistical inference is the significance level. The significance level, also known as alpha, is the probability of rejecting the null hypothesis when it is actually true. It determines the threshold for accepting or rejecting a hypothesis.

A lower significance level indicates a higher level of confidence in the results. A descriptive statistic provides information about the data, but it does not directly measure the reliability of a statistical inference. It simply summarizes and describes the characteristics of the data.

A sample statistic is a numerical value calculated from a sample, such as the mean or standard deviation. While it can be used to make inferences about the population, it does not measure the reliability of those inferences.
A population parameter is a numerical value that describes a population, such as the population mean or proportion.

While it provides information about the population, it does not measure the reliability of inferences made from a sample. In conclusion, the significance level is the measure of reliability in a statistical inference as it determines the probability of making a Type I error, which is rejecting the null hypothesis when it is actually true.
