Answer:

Therefore, the mean commission earned by the five salespeople at Southwest Appliances is $24,000.

Step-by-step explanation:

To find the mean (average) commission of the five salespeople at Southwest Appliances, you need to calculate the sum of all the commissions and divide it by the total number of salespeople.

Sum of commissions = $14,000 + $21,000 + $43,000 + $16,000 + $26,000

Sum of commissions = $120,000

Total number of salespeople = 5

Mean commission = Sum of commissions / Total number of salespeople

Mean commission = $120,000 / 5

Mean commission = $24,000

Therefore, the mean commission earned by the five salespeople at Southwest Appliances is $24,000.

The upper bound of the 95% confidence interval for the average age in the U.S. is 48.29 years.

To determine the upper bound of the 95% confidence interval for the average age in the U.S., we can use the sample data from the survey. The sample size is 1072 people, randomly selected from the U.S. population, with a minimum age of 12. By calculating the average age of the respondents, we can estimate the average age of the entire U.S. population.

Using the given information that the average age of the respondents is 43.56 years, and assuming that the sample is representative of the population, we can calculate the standard error. The standard error measures the variability of the sample mean and indicates how much the sample mean might deviate from the population mean.

Using statistical methods, we can calculate the standard error and construct a confidence interval around the sample mean. The upper bound of the 95% confidence interval represents the highest plausible value for the population average age based on the sample data.

Therefore, based on the provided information and calculations, the upper bound of the 95% confidence interval for the average age in the U.S. is 48.29 years.

The forecast of monthly receipts for July 2011, based on the given equation Y=450+10t, with t=1 in April of the same year, is 460.

The equation Y=450+10t represents a linear relationship between the monthly receipts (Y) and time (t), with an initial value of 450 and a constant rate of increase of 10.

By substituting t=1 in April, we can determine the number of months that have passed since the initial value. In April, t=1, so one month has passed since the initial value.

To find the forecast for July, we need to determine the value of Y when t=4 (July is four months after April). Plugging t=4 into the equation, we get Y=450+10(4) = 450+40 = 490.

Therefore, the forecasted monthly receipts for July 2011 would be 490.

Step-by-step explanation:

A full circle is 360°, and the right angle is 90°. The rest of the angle is 270°, or 4x (from 3x+x).

4x = 270

x=67.5

The point which is √2 distance away from the point (-1, 5) is (-1, 5 - √2).

In order to find a point that is √2 away from (-1, 5), we need to find a point that is at a distance of √2 from (-1, 5). Let the point we need to find be (x, y),

Using the distance formula, we can set up the following equation:

√[(x - (-1))² + (y - 5)²] = √2,

Simplifying this equation,

We get,

(x + 1)² + (y - 5)² = 2,

This equation represents a circle with center (-1, 5) and radius √2.

So, one point that satisfies this equation is (-1, 5 - √2), which is √2 away from (-1, 5).

Answer:

the ordered pair (0, 1/6)

Step-by-step explanation:

To reflect a function across the y-axis, we replace every occurrence of x with -x. Therefore, the function g(x) is given by:

g(x) = f(-x) = 1/6(2/5)^(-x)

To find an ordered pair on g(x), we need to choose a value of x and evaluate g(x). For example, if we choose x = 0, then:

g(0) = 1/6(2/5)^(-0) = 1/6

Therefore, the ordered pair (0, 1/6) is on the graph of g(x).

The equation -sin²θ + cos²θ = sinθ + 1 can be simplified to cos²θ - sinθ - 1 = 0. By applying the Pythagorean identity cos²θ = 1 - sin²θ, we can substitute cos²θ with 1 - sin²θ in the equation.

Starting with the equation -sin²θ + cos²θ = sinθ + 1, we can substitute cos²θ with 1 - sin²θ using the Pythagorean identity. This gives us 1 - sin²θ - sinθ - 1 = 0. Simplifying further, we have -sin²θ - sinθ = 0. Factoring out sinθ, we get sinθ(-sinθ - 1) = 0.

To find the values of θ, we set each factor equal to zero and solve for θ. The solutions are sinθ = 0 and -sinθ - 1 = 0. For sinθ = 0, the solutions are θ = 0 and θ = π. For -sinθ - 1 = 0, we have sinθ = -1, which does not have solutions in the given interval since the sine function ranges from -1 to 1. Therefore, the solutions for the equation on the interval 0 ≤ θ < 2π are θ = 0 and θ = π.

The range of the interval where p-value 0.2514 lies is given by option a. 0.2001 to 5000.

To find the p-value for the test,

calculate the z-score and then use the z-table or a calculator to find the corresponding p-value.

The z-score is calculated using the formula,

z = (sample mean - population mean) / (population standard deviation / √(sample size))

here,

Sample mean (X) = 798 hours

Population mean (μ) = 800 hours

Population standard deviation (σ) = 20 hours

Sample size (n) = 36

Substituting these values into the formula, we have,

z = (798 - 800) / (20 /√(36))

= -2 / (20 / 6)

= -2 / 3

= -0.67

Now, the p-value associated with the z-score of -0.67  use a calculator.

Using a z-calculator,

The area to the left of -0.67 is approximately 0.2514.

However, since we are testing the hypothesis that the mean lifetime of light bulbs is less than 800 hours (one-tailed test),

The area to the left of -0.67.

The probability that the vaccine is not effective for one and only one individual out of 20 individuals can be calculated using the binomial probability formula. The correct answer is 0.0179.

To calculate the probability that the vaccine is not effective for one and only one individual out of 20 individuals, we can use the binomial probability formula.

The formula is given by P(X = k) = C(n, k) * \(p^k\) * \((1-p)^(n-k)\), where P(X = k) is the probability of getting exactly k successes, n is the number of trials, p is the probability of success in a single trial, and C(n, k) is the binomial coefficient.

In this case, we want to find the probability of one individual out of 20 not being protected by the vaccine, which is equivalent to one failure out of 20 trials. The probability of the vaccine not being effective for one individual is 1 - 0.95 = 0.05.

Using the binomial probability formula, we substitute n = 20, k = 1, and p = 0.05, and calculate the probability P(X = 1). The correct answer is 0.0179, which is the probability that the vaccine is not effective for one and only one individual out of 20 individuals.

(1) P(X ≤ 22)

We integrate the function from x = -∞ to x = 22, we get:

We separated the integral to use the data from the graph.

(2) P(X > 21)

We integrate the function from x = 21 to x = ∞, we get:

(3) The Q1 is the value x = a of the interval (-∞, a) that gives a probability equal to 0.25. So we must find x such that:

(4) The median is the value x = a of the interval (-∞, a) that gives a probability equal to 0.5. Proceeding as before, we have:

(5) The Q3 is the value x = a of the interval (-∞, a) that gives a probability equal to 0.75. Proceeding as before, we have:

(6) The IQR is given by the difference between Q3 and Q1. Using the results from above, we get:
