Step-by-step explanation:

The 90% confidence interval for the average speed of all the cars passing through the intersection is (41.29, 42.71) miles per hour.

To calculate the confidence interval, we can use the formula:

Confidence interval = Sample mean ± (Critical value * Standard error)

Given that the sample mean is 42 miles per hour and the standard deviation is 4.2 miles per hour, we need to determine the critical value and the standard error.

Since we have a sample size of 85, we can use the t-distribution with (n-1) degrees of freedom to find the critical value. With a 90% confidence level, the corresponding critical value for a two-tailed test is approximately 1.66.

The standard error is calculated as the standard deviation divided by the square root of the sample size:

Standard error = (Standard deviation) / √(Sample size)

Standard error = 4.2 / √85 ≈ 0.456

Now we can plug in the values into the confidence interval formula:

Confidence interval = 42 ± (1.66 * 0.456)

Confidence interval ≈ (41.29, 42.71)

Therefore, the 90% confidence interval for the average speed of all the cars passing through the intersection is (41.29, 42.71) miles per hour.

Based on the given data and calculations, we can conclude that with 90% confidence, the average speed of all the cars passing through the intersection falls within the range of 41.29 to 42.71 miles per hour.

Answer:

Equation 1: (500×5)+75

Equation 2: (20×5)×7

Total Revenue: $1,875

Step-by-step explanation:

For equation 1 we multiply the companys $500 an hour flat rate by the number of hours the party was (5), then add the company's $75 set up fee for a total of $2,575.

For equation 2 we multiply the company's hourly pay (20) by the number of hours worked (5), after that we multiply the number of employees (7) for a total of $700.

Finally to figure out the actual revenue from the event we subtract the amount the company paid the employees ($700) from the total paycheck for hosting the party ($2,575) for a final total of $1,875.

Step-by-step explanation:

f(x) = 2x + 1. Let y = f(x).

Then y = 2x + 1, 2x = y - 1, x = (y - 1)/2.

If h(x) is the inverse of f(x), then h(x) = (x - 1)/2 = 0.5x - 0.5.

Yes, the polynomial p(z)=anz^n an-1z^n-1 .. a0 is written in factored form as p(z)=an(z-z1)^d1 (z-z2)^d2 …(z-zr)^dr.

To show that if the polynomial p(z) is written in factored form as\(p(z) = an(z-z1)^d1 (z-z2)^d2 ...(z-zr)^dr\), then the coefficients satisfy the following relations:

The degree of the polynomial p(z) is n, which means that the sum of the exponents of the factors in the factored form is equal to n:

\(d1 + d2 + ... + dr = n\)

The coefficient of the highest degree term in p(z) is an, which means that:

\(an = ad1d2*...*dr\)

To prove these relations, we start by expanding the factored form of p(z) using the distributive property:

\(p(z) = an(z-z1)^d1 (z-z2)^d2 ...(z-zr)^dr\)

\(= an*(z^d1 - z1^d1)(z^d2 - z2^d2)...*(z^dr - zr^dr)\)

The degree of p(z) is the highest power of z in this expression, obtained by adding up the highest exponents of z in each term.

Since each factor \((z - zi)\)has a maximum exponent of di, the highest power of z in\(p(z) is d1 + d2 + ... + dr.\)

\(n = d1 + d2 + ... + dr\)

The coefficient of the highest degree term in the expanded form of p(z) is obtained by multiplying the highest degree terms in each factor.

we compare it with the coefficient of the highest degree term in the original polynomial p(z).

\(an*(z1^d1)(z2^d2)...*(zr^dr)\)

On the other hand, the coefficient of the highest degree term in p(z) is the coefficient of \(z^n,\) which is an. Therefore, we have:

\(an = an*(z1^d1)(z2^d2)...*(zr^dr)\)

Dividing both sides by the product of the z-terms, we get:

\(1 = (z1^d1)(z2^d2)...*(zr^dr)\)

Multiplying both sides by an, we get:

\(an = ad1d2*...*dr\)

This proves that the coefficients of the polynomial p(z) satisfy the relations stated above.

The bag-filling machine works correctly at the 408-gram setting. And the Alternative hypothesis is that The machine underfills the bags.

In this scenario, the null hypothesis states that the bag-filling machine works correctly at the 408-gram setting. The alternative hypothesis suggests that the machine underfills the bags, indicating a deviation from the desired weight.

The null hypothesis can be denoted as:

H0: μ = 408

where μ represents the population mean weight of the filled bags.

The alternative hypothesis can be denoted as:

H1: μ < 408

This hypothesis suggests that the population's mean weight is less than 408 grams.

By setting a level of significance of 0.01, we are indicating that we are willing to accept a 1% chance of Type I error (rejecting the null hypothesis when it is true).

To test these hypotheses, we can perform a one-sample t-test using the sample mean weight of the 15 bags (402 grams), the population standard deviation (assuming it is known or estimated), and the sample size.

The correct answer is B. The range does not use all the observations. The range is a measure of dispersion that only considers the difference between the maximum and minimum values in a data set.

This means that it does not take into account the distribution of the other observations in the data set. On the other hand, the standard deviation considers all the observations and measures how far, on average, each observation is from the mean. It is a more comprehensive measure of dispersion because it takes into account the spread of the data around the mean. Therefore, the standard deviation is generally considered a more desirable measure of dispersion compared to the range. The range does not use all the observations. The range, which is the difference between the highest and lowest values, only considers the two extreme data points. In contrast, the standard deviation takes into account the deviation of all observations from the mean, providing a more comprehensive measure of dispersion. The range can be less reliable in cases where extreme values are present, as it does not reflect the variability within the entire dataset.

Confidence interval refers to a statistical measure that helps quantify the amount of uncertainty present in a sample's estimate of a population parameter.

This measure expresses the degree of confidence in the estimated interval that can be calculated from a given set of data. In this scenario, the task is to build a 95% confidence interval for the regression line's slope. The regression analysis output has already been given. According to the output given, the estimated regression model is:y = 25,000 + 9,000 x, where x represents the number of miles the car has been driven and y represents the car's selling price.

The formula to calculate the 95% confidence interval for the slope is:Slope ± t · SE, where Slope is the point estimate for the slope, t represents the critical t-value for a given level of confidence and degrees of freedom, and SE represents the standard error of the estimate. The value of t can be calculated using the degrees of freedom and a t-table. Here, the number of pairs in the sample size is 20, and the model uses two parameters.

Therefore, the degrees of freedom would be 20 - 2 = 18.The critical t-value for a 95% confidence interval and 18 degrees of freedom is 2.101. Using the formula given above, we can calculate the 95% confidence interval for the slope as follows:Slope ± t · SE= 9000 ± (2.101)(700) ≈ 9000 ± 1,467.7 = [7,532.3, 10,467.7]Therefore, the 95% confidence interval for the slope is [7,532.3, 10,467.7]. This means that we are 95% confident that the true value of the slope for this model falls within the interval [7,532.3, 10,467.7].

It implies that the price of the car increases by $7,532.3 to $10,467.7 for each mile driven by the car. In conclusion, a 95% confidence interval has been calculated for the regression line's slope, which indicates that the actual slope of the model lies between the range [7,532.3, 10,467.7].

If the takt time for a process is 150 ​seconds, what is the demand for the​ process. The demand is 24 units per hour.

Calculating the demand for a process with a takt time of 150 seconds is relatively simple. To begin, we need to convert the takt time from seconds to hours. This can be done by dividing the takt time by 3,600 (the number of seconds in an hour).

The calculation is as follows:

150 seconds / 3,600 seconds = 0.041666667 hours

Next, we need to calculate the demand for the process by dividing 1 hour by the takt time (in hours). The calculation is as follows:

1 hour / 0.041666667 hours = 24 units per hour

Therefore, the demand for the process is 24 units per hour.

The z-score for a male systolic blood pressure of 110 mmHg is -1.67 and the z-score for a male systolic blood pressure of 150 mmHg is 1.67 respectively.

To calculate the z-scores, we use the formula:
z = (x - μ) / σ
Where x is the value we want to standardize, μ is the mean of the distribution, and σ is the standard deviation.
For 110 mmHg:
z = (110 - 130) / 12 = -1.67
For 150 mmHg:
z = (150 - 130) / 12 = 1.67
So the z-score for a systolic blood pressure of 110 mmHg is -1.67 and the z-score for a systolic blood pressure of 150 mmHg is 1.67.
The z-score tells us how many standard deviations away from the mean the observation is. A negative z-score indicates that the observation is below the mean, while a positive z-score indicates that the observation is above the mean. In this case, a z-score of -1.67 for 110 mmHg means that this observation is 1.67 standard deviations below the mean, while a z-score of 1.67 for 150 mmHg means that this observation is 1.67 standard deviations above the mean.

To compare the ages of voters who voted Republican to those who voted Democrat, Evan would need to collect data on the ages of voters from both groups. He can then calculate measures of central tendency (such as the mean and median) and measures of variability (such as the range and standard deviation) for each group and compare them.

If Evan thinks that there will be greater variability in the ages of voters who voted Democrat, he may want to use a measure of variability such as the standard deviation to compare the spread of ages in each group. A larger standard deviation would indicate greater variability in the ages of voters in that group.

Evan could also create a box plot for each group to compare the distribution and variability of ages in each group. The box plot would show the median, quartiles, and outliers for each group, allowing for a visual comparison of the spread of ages in each group.

The general term or nth term for the sequence is an = n + 1, and the 8th term (a8) is 9.

The given sequence starts with 2, and each subsequent term is obtained by adding 1 to the previous term. We can observe that the pattern is to increase each term by 1, resulting in the sequence 2, 3, 4, 5, and so on.

To express this pattern in terms of the nth term, we can see that each term is obtained by adding 1 to the value of n. Therefore, the general term or nth term for the sequence is given by an = n + 1. To find the 8th term (a8), we substitute n = 8 into the expression for the nth term:

a8 = 8 + 1 = 9.

Hence, the 8th term of the sequence is 9.

The given sequence starts with 2, and each subsequent term is obtained by adding 1 to the previous term. This pattern of incrementing each term by 1 is consistent throughout the sequence.

To express this pattern in terms of the nth term, we notice that each term corresponds to the value of n incremented by 1. Therefore, we can define the general term or nth term of the sequence as an = n + 1, where n represents the position of the term in the sequence.

Substituting n = 8 into the expression for the nth term, we can calculate the 8th term (a8) as 8 + 1 = 9. Therefore, the 8th term of the sequence is 9.
