Approximately 9.5% of the racers did not complete the marathon.

The total of those who quit and those who were disqualified represents the number of runners who did not finish the marathon

Number who did not complete = 12 + 8 = 20

To find the percentage of racers who did not complete the marathon, we need to divide this number by the total number of racers who started the marathon (210) and multiply by 100

Percentage who did not complete is

= (20 / 210) x 100

= 9.523%

Rounding this to the nearest tenth of a percent gives us a final answer of 9.5%. Therefore, approximately 9.5% of the racers did not complete the marathon.

The two consecutive integer numbers are 11 and 12, and the inequality is:

11 < √134  < 12

Here we just need to find two integers x and y, such that:

x^2 < 134

134 < y^2

Such that x and y are also consecutive, so y = x + 1.

Then we can write the inequality:

x < √134 < y

The numbers are:

11*11 = 121 (the smaller integer)

12*12 = 144 (the larger integer).

Then the complete inequality is:

We have the parabola as;

x^2 + 5x - 6

Step-by-step explanation:

Here, we want to get a parabola that passes through the points (1,0) and (-6,0)

The general form of a quadratic equation is;

y = ax^2 + bx + c

We have two x-intercepts at x = 1 and x = -6

A quadratic equation is expected to have two roots only and that means we have these two values as the roots

Hence, we have ;

(x-1) and (x + 6)

The parabola is thus;

(x-1)(x + 6)

= x(x + 6) -1(x + 6)

= x^2 + 6x - x -6

= x^2 + 5x - 6

To calculate velocity, we need to use the equation:

Velocity = M * P / Y

Given:

M = 1,000

P = 2.25

Y = 2,000

Plugging in the values:

Velocity = 1,000 * 2.25 / 2,000

Simplifying:

Velocity = 2.25 / 2

The result is:

Velocity = 1.125

The True statement about hypothesis testing is: d) The critical value depends on the significance level.

In hypothesis testing, the critical value is the threshold value used to determine whether to reject or fail to reject the null hypothesis. It is chosen based on the desired significance level, which represents the maximum acceptable probability of committing a type I error (rejecting the null hypothesis when it is true). The critical value is compared to the test statistic to make the decision.

The significance level, denoted by α, is determined by the researcher before conducting the hypothesis test and represents the acceptable level of risk for making a type I error. It is typically set to a small value, such as 0.05 or 0.01.

The test statistic, on the other hand, is calculated based on the observed data and the specific hypothesis being tested. It is used to assess the evidence against the null hypothesis and determine whether it is sufficiently significant to reject it.

Therefore, the correct statement is that the critical value depends on the significance level, as it is chosen to control the probability of making a type I error.

Therefore the correct option is d)

The probability that the length of a component lies between 19 and 21 centimeters is 0.0376.

What is probability?

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.

Given:

Population mean, µ = 14

Population standard deviation, σ = 3

Probability that the length of a component lies between 19 and 21 centimeters

= P(19 <  X  < 21)

= P( (19 - 14) / 3 < (X - µ) / σ < (21 - 14) / 3)

= P(1.67 < z < 2.33)

= P(z < 2.33) - P(z < 1.67)

Using excel function:

= NORM.S.DIST(2.33,1) - NORM.S.DIST(1.67,1)

= 0.9901 - 0.9525

= 0.0376

Hence, the probability that the length of a component lies between 19 and 21 centimeters is 0.0376.

The percentage change in temperature is 19.0%.

The percentage is a ratio that can be expressed as a fraction of 100.

Given that, the temperature rises from 21c to 29c.

The change in temperature is:

29c - 21c

= 4c

The percentage change in temperature from 21c is:

percentage change = (4c/21c)×100

                                 =4/21×100

                                 = 19.0%

The greatest possible error for her actual measurement 0.5 pounds

What is a mistake, exactly?

A mistake is an inaccurate or incorrect action (the Latin word error, which means "wandering"). Sometimes the terms "mistake" and "error" are used synonymously. The Latin word "errare," which means "to stray," is the source of the etymology.

Given:

Beatriz calculated the error range to be 23.5 to 24.5 pounds.

How much room did she have for error in her actual measurement?

Solution:

We initially locate the median of the supplied numbers before calculating the margin of error.

23.5 and 24.5 as the median

\(M=\frac{23.5+34.5}{2}= \frac{48}{2}=24\)

Therefore, the largest inaccuracy is 24.5-24 = 0.5 pounds.

Step-by-step explanation:

Extrapolation is the use of the regression line to estimate a mean of y-values for an x-value that is far outside the x-range of data.

What is extrapolation?

A statistical technique called extrapolation aims to understand the unknown data from the known data. It uses historical data to attempt to predict future data. For instance, using the current population size and growth rate to project the size of a population in a few years.

Predicting hypothetical values outside of a specific data set is the goal of extrapolation.

Contrary to interpolation, which typically focuses on estimating past values, extrapolation is used to predict unknown future values due to its predictive nature.

Hence, extrapolation is the use of the regression line to estimate a mean of y-values for an x-value that is far outside the x-range of data.

Answer:the answer c

Step-by-step explanation:

The x-intercept is 4 while the y-intercept is -4 so option (B) is correct.

The graph is a geometrical representation of a function and can be plotted by taking x's and y's corresponding values within the interval.

For example plot of y = x³ ,y = sinx.

As per the given,

The equation of line is y = -2x² + 9x - 4

At x = 0, y = -4 so (0,-4) will be the y-intercept.

At x = 4,y = -2 x 4 + 9 x 4 - 4 = 0 so (4,0) will be x-intercept.

Hence "The x-intercept is 4 while the y-intercept is -4".

At the fidelity credit union, the mean number of customers who arrive hourly at the drive-through window is 4.9. It is required to determine the probability of fewer than 1 customer arriving in any hour.

Answer: 0.00796.

The solution to this problem is discussed below:

The given information implies that the mean value of the Poisson distribution, λ = 4.9.

In a Poisson distribution, the probability of x occurrences during a particular interval is given by:

P(x; λ) = e–λ λx / x!

Where e is approximately equal to 2.71828.

Let x = 0 since we need the probability of less than 1 customer in an hour.

P(x < 1) = P(x = 0) + P(x = 1) + P(x = 2) + …P(x < 1) = e-4.9 4.90 / 0!P(x < 1) = e-4.9 1P(x < 1) = 0.00796

A. According to the statistics reviewed in the course, the average number of people killed by US police every year is approximately 1,000.

However, it's important to note that this number may not be entirely accurate due to incomplete data and underreporting.

The use of deadly force by police has been a topic of significant controversy and debate in recent years. Many argue that the high number of police killings is indicative of systemic issues within law enforcement agencies, such as racism, insufficient training, and a lack of accountability. Others argue that police officers are forced to make split-second decisions in dangerous situations, and that any use of force is justified in order to protect public safety.

In response to these concerns, many organizations have called for reforms to police practices and procedures. Some of these reforms include increased transparency, community policing initiatives, de-escalation training, and the implementation of body cameras on patrol officers.

While progress has been made in some areas, more work is needed to reduce the number of deaths caused by police in the United States. It will require a concerted effort from law enforcement officials, policymakers, and communities across the country to address this issue and ensure that all Americans can feel safe and protected when interacting with the police.
