Answer:

d = 1 + 3p  

Step-by-step explanation:

Leon already ran 1 miles on his own and he is expected to cover a distance d of 3 miles during each practice. The number of practices is expressed as p and the distance covered is expressed as d.

For every track practice he is expected to cover a distance of 3 miles. Recall he has already cover 1 mile on his own.

Therefore, the relationship between the practices p and the distance d can be expressed as follows.

number of track practice = p

distance covered = d

The distance covered  d in miles is 1 miles plus the number of track practice p multiply by 3

d = 1 + 3p

To find the equation of a line, we need to determine its slope and its y-intercept.

Let's use the given graph to find the slope of the line.The slope of the line can be found as shown

:Slope = Change in y-coordinate / Change in x-coordinate

Let's select two points on the line and find the change in the y-coordinate and the change in the x-coordinate.

Using points (-12, 5) and (12, -7),

we get:Change in y-coordinate = -7 - 5

= -12

Change in x-coordinate = 12 - (-12)

= 24

Thus, the slope of the line is:Slope = -12/24

Slope = -1/2

The slope-intercept form of the equation of a line is given as:y = mx + b

where m is the slope of the line and b is the y-intercept.

We have found the slope of the line. To find the y-intercept, we can use any point on the line.Using point (0, -2),

we get:-2 = (-1/2)(0) + b-2

= b

Thus, the y-intercept of the line is b = -2.Substituting the values of m and b in the slope-intercept form of the equation of a line, we get:y = -1/2x - 2

This is the required equation of the line in fully simplified slope-intercept form.

In a multiple regression model, the error term 'e' is assumed to be a random variable with a mean of zero (option A).

In a multiple regression model, we aim to estimate the relationship between a dependent variable (y) and multiple independent variables (x1, x2, x3, ..., xn).

The model assumes that the relationship between the independent variables and the dependent variable can be represented by a linear equation: y = β0 + β1x1 + β2x2 + ... + βnxn + e

In this equation, 'e' represents the error term or residual, which captures the variation in the dependent variable that is not explained by the independent variables. It includes factors such as measurement error, unobserved variables, and other sources of randomness.

By assuming that the error term has a mean of zero, we are stating that, on average, the errors balance out and do not systematically overestimate or underestimate the true value of the dependent variable. This assumption helps ensure that the model is unbiased.

The assumption of a mean of zero implies that, over repeated observations, the sum of the errors will be close to zero, indicating that, on average, the model's predictions are centered around the true values of the dependent variable.

This assumption also aligns with the idea that the model's estimated coefficients (β0, β1, β2, ..., βn) represent the average effect of the independent variables on the dependent variable, assuming that other factors remain constant.

Additionally, the assumption of a mean of zero for the error term is often coupled with the assumption of a constant variance (homoscedasticity). This means that the spread of the errors is consistent across the range of the independent variables.

The assumption of a normally distributed error term with a mean of zero and constant variance is crucial for conducting statistical inference, hypothesis testing, and constructing confidence intervals in multiple regression analysis.

In summary, assuming a mean of zero for the error term in a multiple regression model ensures that, on average, the model's predictions are unbiased, and it facilitates statistical analysis and interpretation of the model's coefficients.

The IQR becomes a 1.5.

IQR stands for Interquartile Range, which is a measure of variability in a set of data. It is calculated as the difference between the upper quartile (Q3) and the lower quartile (Q1) of the data.

To determine how the IQR changes, we first need to find the quartiles of the data set.

Arranging the data set in ascending order:

5.5, 6, 6.5, 7, 7.5, 8, 8, 8.5

The median is 7, which is the second quartile (Q2).

To find the first quartile (Q1), we find the median of the lower half of the data set:

5.5, 6, 6.5, 7

The median is 6.25.

To find the third quartile (Q3), we find the median of the upper half of the data set:

7.5, 8, 8, 8.5

The median is 8.

Therefore, the IQR = Q3 - Q1 = 8 - 6.25 = 1.75.

If we add a shoe size of 7 to the data set, the new data set becomes:

5.5, 6, 6.5, 7, 7, 7.5, 8, 8, 8.5

Arranging the new data set in ascending order:

5.5, 6, 6.5, 7, 7, 7.5, 8, 8, 8.5

The median is 7, which is still the second quartile (Q2).

To find the first quartile (Q1), we find the median of the lower half of the data set:

5.5, 6, 6.5, 7, 7

The median is 6.5.

To find the third quartile (Q3), we find the median of the upper half of the data set:

7.5, 8, 8, 8.5

The median is 8.

Therefore, the IQR = Q3 - Q1 = 8 - 6.5 = 1.5.

So, the answer is: the IQR becomes a 1.5.

When the sample size increases, the margin of error decreases. A margin of error refers to the extent to which survey results are likely to deviate from the real population. The sample size is a critical component of any survey because it directly affects the margin of error.

By increasing the sample size, the margin of error decreases. With a larger sample size, the sample mean tends to be more accurate, making the margin of error relatively smaller. Thus, the survey results are likely to be more accurate and representative of the population.According to statistics, the margin of error is proportional to the sample size. This means that a small sample size yields a wide margin of error while a larger sample size yields a small margin of error. This relationship is due to the fact that increasing the sample size reduces the variability of the sampling distribution. By reducing variability, the sample mean becomes more precise, making the margin of error smaller. Therefore, the answer to this question is option B. The margin of error decreases as the sample size increases.

As the sample size increases, the margin of error decreases.

The margin of error is the amount of error we can tolerate while still believing that the sample statistics are relatively close to the population parameters.

~Margin of error calculation is useful when it comes to designing and analyzing survey results or experiments, as it aids in determining the sample size required.

Increasing the sample size makes the standard error of the mean decrease, causing the margin of error to decrease.

In statistics, sample size is the number of individuals from a population that researchers select to conduct research.

In general, the larger the sample size, the more representative the sample is of the population from which it was drawn, and the more accurate the results are likely to be.

This aids in the reduction of the margin of error in a given sample.

On the other hand, mean refers to the sum of all the values in a dataset divided by the number of observations.

It represents the central tendency of the dataset.

However, the size of the mean does not affect the margin of error because it is a measure of central tendency and not sample variation.

Therefore, option (b) is the correct answer; as the sample size increases, the margin of error decreases.

Let's first draw the rhombus and label the diagonals:

================================

     A

     o

    / \

3.5   12

/       \

o----x----o

\       /

3.5   12

  \   /

   o B

================================

Let the rhombus be ABCD, with AB = BC = CD = DA. Let O be the center of the circle, which is also a vertex of the rhombus. Then, OA and OB are radii of the circle, and they are also perpendicular bisectors of sides AB and BC, respectively. Therefore, triangle AOB is a right triangle, and we can use the Pythagorean Theorem to find the length of OB:

OA = OB = OC = OD (since O is the center of the circle)

AB = BC = 12 (since 12 is the length of diagonal AC)

AO^2 = AB^2/4 + OB^2 (since AO and OB are the legs of right triangle AOB)

Substituting AB = 12 and simplifying, we get:

OB^2 = AO^2 - AB^2/4

= (3.5/2)^2 - 12^2/4

= 49/16 - 144/4

= 49/16 - 36

= 1/16

Taking the square root of both sides, we get:

OB = \sqrt{1/16} = 1/4

Now, the circle is tangent to sides AB and BC, so its diameter must be perpendicular to these sides. Therefore, the diameter of the circle is equal to the length of diagonal BD, which is the hypotenuse of right triangle AOB:

BD^2 = AB^2 + OB^2

= 12^2 + (1/4)^2

= 144 + 1/16

= 577/16

Taking the square root of both sides, we get:

BD = \sqrt{577}/4

Finally, the area of the circle is given by:

A = pi*(BD/2)^2

= pi*(\sqrt{577}/8)^2

= pi*577/64

Therefore, the exact value of the circle area is (577/64)*pi.

The critical value for a right-tailed t-test with a significance level (α) of 0.025 and a sample size (n) of 11 is approximately 2.718.

The critical value is a threshold used to determine whether a test statistic is statistically significant. In a t-test, it helps determine if the sample mean is significantly different from a hypothesized population mean. The critical value for a specific significance level and test type can be found using statistical tables or calculators.

For a right-tailed t-test, we are interested in determining if the sample mean is significantly larger than the hypothesized population mean. In this case, the significance level (α) is set to 0.025, indicating a 2.5% chance of observing a sample mean as extreme or more extreme than what is obtained, assuming the null hypothesis is true. With a sample size (n) of 11, the degrees of freedom for this test would be n - 1 = 10.

Looking up the critical value for a right-tailed t-test with 10 degrees of freedom and a significance level of 0.025, we find that the value is approximately 2.718. This means that if the calculated test statistic (t-value) is greater than 2.718, we would reject the null hypothesis in favor of the alternative hypothesis, indicating a statistically significant result.

Convincing can also be described by other words like cogent, sound, telling, and valid.

Despite the fact that all of these words have the same meaning—"having such force as to compel serious attention and typically acceptance”—convincing denotes the ability to go over resistance or hesitation to accept.

When you say that someone or something is compelling, you indicate that they persuade you that something is real, accurate, or true.

Three fundamental strategies for persuading a listener to agree with you are ethos, logos, and pathos.
