There is a clothing store in Bartlesville. The owner has devised his own method of pricing items. A vest costs $20, socks cost $25, a tie costs $15 and a blouse costs $30. Using the method, how much would underwear cost?

An equation to accompany each array is as follows;

(r³ - 3) × 1 = 24, (r² + 3) × 2 = 24, (r² - 1 ) × 3 = 24, (r² - 3 ) × 4 = 24, (r) × 8 = 24, (r - 1 ) × 12 = 24, and (r - 2) × 12 = 24 where, r = 3.

The rectangular array will be considered as rows.

Now, when we take the first side as the length represented by L and the second side as the width represented by W.

Area of a rectangle is given by the formula;

Area = length * width

Area = L * W

We are modeling a rectangular quilt with the 24 paper squares and as such the total area of the quilt is 24 squares which means;

24 × 1 = 24

All squares are arranged in a single row;

(r³ - 3) × 1 = 24

12 × 2 = 24

12 squares arranged in 2 rows.

(r² + 3) × 2 = 24

8 × 3 = 24

8 squares arranged in 3 rows.

(r² - 1 ) × 3 = 24

6 × 4 = 24

6 squares arranged in 4 rows.

(r² - 3 ) × 4 = 24

3 × 8 = 24

3 squares arranged in 8 rows.

(r) × 8 = 24

2 × 12 = 24

2 squares arranged in 12 rows.

(r - 1 ) × 12 = 24

1 × 24 = 24

Specifications dictate values should be between 900 and 1,000 megohms.

Explanation:

Answer:

The mean of the distribution is 4.00 and the standard deviation is 2.31

Explanation:

Given

Range = 2 to 10

Type of distribution = uniform distribution

Required

1. Mean

2. Standard Deviation

The mean of uniform distribution is calculated as thus;

\(Mean = \frac{1}{2}(a + b)\)

Where b and a are the intervals of the distribution

b = upper bound = 10

a = lower bound = 2

So,

\(Mean = \frac{1}{2}(a + b)\)

Substitute 10 for b and 2 for a

\(Mean = \frac{1}{2}(2 + 10)\)

\(Mean = \frac{1}{2}(12)\)

\(Mean = \frac{1}{2} * 12\)

\(Mean = 6\)

\(Mean = 6.00\) (Approximated to 2 decimal places)

The standard deviation of uniform distribution is calculated as thus;

σ = √σ²

Where σ represents the standard deviation and σ² represents the variance.

Calculate variance

σ² = Var

\(Var = \frac{(b-a)^2}{12}\)

Substitute 10 for b and 2 for a

\(Var = \frac{(10 - 2)^2}{12}\)

\(Var = \frac{8^2}{12}\)

\(Var = \frac{64}{12}\)

\(Var = 5.33\)

Recall that

σ = √σ² = √Var

Substitute 5.33 for Var

σ = √5.33

σ = 2.309401076758503

σ = 2.31 (Approximated)

Hence, the mean of the distribution is 4.00 and the standard deviation is 2.31

a)  The total revenue (TR) function can be calculated by multiplying the unit selling price by the quantity sold.

TC = FC + TVC = 400,000 + 3,000,000 = 3,400,000 birr.

The profit function (P) can be determined by subtracting the total cost from the total revenue, so P = TR - TC = 100Q - 3,400,000 birr.

b) The breakeven point can be found by setting the profit function equal to zero, as this is the point where total revenue equals total cost.

Sales Volume = 34,000 units * 100 birr/unit = 3,400,000 birr. Hence, the breakeven point in terms of sales volume is 3,400,000 birr.

Answer:

Explanation:

To find the sample variance and standard deviation, we need to first find the mean of the sample, and then use that to calculate the variance and standard deviation.

The mean of the sample is:

(15 + 37 + 23 + 18 + 17 + 10) / 6 = 16

Next, we'll find the difference between each value and the mean, square those differences, and divide the sum of the squared differences by the sample size minus one (n - 1):

(15 - 16)^2 = 1

(37 - 16)^2 = 361

(23 - 16)^2 = 49

(18 - 16)^2 = 4

(17 - 16)^2 = 1

(10 - 16)^2 = 36

The sum of the squared differences is: 1 + 361 + 49 + 4 + 1 + 36 = 452

The sample variance is: 452 / (6 - 1) = 452 / 5 = 90.4

Finally, the sample standard deviation is the square root of the sample variance:

The sample standard deviation is: sqrt(90.4) = 9.49

So, the sample variance is 90.40 and the sample standard deviation is 9.49.

sample variance is 90.40 and the sample standard deviation is 9.49

The specification 'leaves found in deciduous forest and leaves found in tropical forest' should not be used when making this dichotomous key. It is not part of a classification system.

A dichotomous key is a methodology employed by taxonomists to identify organisms from different taxonomic groups. The dichotomous keys are always funded on phenotypic traits. Dichotomous keys can be considered as two different options to identify a given feature of an organism.

Monocots are the plants having only one cotyledon or seed with only one leaf also called monocotyledons. Dicots are the plants having two cotyledons or seed with two leaves.

Monocots and dicots have few characters that make them easily recognizable such as venation pattern: The arrangement of veins in a leaf is called the venation pattern; dicots have a reticulate or network of veins type venation, while monocots have parallel venation.

Therefore, The specification 'leaves found in deciduous forest and leaves found in tropical forest' should not be used when making this dichotomous key. It is not part of a classification system.

Approximately 97.06% of the world's population lives in countries other than Canada and Guam.

To find out what percentage of the world's population lives in countries other than Canada and Guam, we need to know the population of Canada, the population of Guam, and the total population of the world. We can then subtract the population of Canada and Guam from the total population of the world to find out how many people live in countries other than Canada and Guam.

Finally, we can divide this number by the total population of the world and multiply by 100 to find out what percentage of the world's population lives in countries other than Canada and Guam. Let's go through the steps. According to the World Bank, the population of Canada in 2021 is approximately 38 million.

According to the CIA World Fact book, the population of Guam in 2021 is approximately 170,000. To find the total population of the world, we can use the United Nations' estimate of 7.9 billion people as of 2021. So, the population of countries other than Canada and Guam is:

7.9 billion - 38 million - 170,000 = 7,747,830,000

Now, to find out what percentage of the world's population lives in countries other than Canada and Guam, we divide this number by the total population of the world and multiply by 100:

(7,747,830,000 ÷ 7,900,000,000) x 100 = 97.06%

Therefore, approximately 97.06% of the world's population lives in countries other than Canada and Guam.

The value of the z-test statistic is 1. There is not sufficient evidence at the 0.02 level that the jeeps outperform the manufacturer's MPG rating.

To determine whether there is sufficient evidence at the 0.02 level that the jeeps outperform the manufacturer's MPG rating, we need to perform a hypothesis test.

In this case, our null hypothesis is that the jeeps do not outperform the manufacturer's MPG rating, and our alternative hypothesis is that the jeeps do outperform the manufacturer's MPG rating. We can use a one-sample z-test to test this hypothesis.

To perform the z-test, we need to calculate the z-test statistic, which is given by the following formula:

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

In this case, the sample mean is 55.9, the population means is 55.8, the standard deviation is 2.09, and the sample size is 220. Plugging these values into the formula above, we get:

z = (55.9 - 55.8) / (2.09 / √(220))

z = 0.05 / 0.05

z = 1

Therefore, the value of the z-test statistic is 1.

Next, we need to find the critical value for the z-test at the 0.02 level. We can use a z-table or a z-score calculator to find the critical value. For a one-tailed test at the 0.02 level, the critical value is 2.33.

Since the z-test statistic is less than the critical value, we cannot reject the null hypothesis at the 0.02 level. Therefore, there is not sufficient evidence at the 0.02 level that the jeeps outperform the manufacturer's MPG rating.

167 randomly selected students

mean sample = 26.2

Standard deviation = 6.8

Definition of variables

confidence level, CL = 99%

mean sample, μ = 26.2

standard deviation, SD = 6.8

sample size, n = 167

since it random variable: t - distribution

degree of freedom = 167 - 1 = 166

significance level, α = 1 – confidence level = 1 - 0.99 = 0.01

The formula for the confidence interval is given by

CI = μ ± t ( SD / √n )

plugging the values

CI = 26.2 ± 2.606 ( 6.8 / √167 )

= 26.2 - 2.606 ( 6.8 / √167 )   OR    26.2 + 2.606 ( 6.8 / √167 )

= 24.828    OR     27.571    

The confidence interval is 24.828 < μ < 27.571

from the confidence interval 24.6 hg < μ < 28.4 hg

n = 14 sample

μ = 26.5 ​hg

SD =2.3 ​hg

26.5 - 24.6 = 28.4 - 26.5 = 1.9

1.9 = t * SD / √n

t = 1.9 * √14 / 2.3 = 3.091
