The value of x in the rectangle is 36.

A rectangle is a quadrilateral with opposite sides equal to each other and opposite sides parallel to each other.

All angles measure 90∘ in a rectangle. The sum of angles in a rectangle is 360 degrees.

Therefore, let's find the value of x in the angles.

Hence,

∠2 = x + 30

∠5 = 2x - 48

Therefore,

∠2 + ∠5 = 90°

x + 30 + 2x - 48 = 90

3x - 18 = 90

3x = 90 + 18

3x = 108

divide both sides by 3

x = 108 / 3

x = 36

Therefore,

x = 36

In 2012, a company made $410,000 in sales in Seattle but only making $255,000 in sales in Portland. Fulfill each of the following claims:

a. Seattle outsold Portland in sales by 60.78%.

b. Portland's sales lagged Seattle's by 60.78%.

c. Sales in Portland were 62.2% of those in Seattle.

a. Seattle's sales were ___% larger than Portland's.

To calculate the percentage difference between the two sales figures, we can use the following formula:

Percentage difference = ((larger value - smaller value) / smaller value) x 100%

Substituting the values, we get:

Percentage difference = ((410,000 - 255,000) / 255,000) x 100%

Percentage difference = 155,000 / 255,000 x 100%

Percentage difference = 0.6078 x 100%

Percentage difference = 60.78%

Therefore, Seattle's sales were 60.78% larger than Portland's.

b. The sales in Portland were ___% less than those in Seattle.

Since Portland's sales were smaller than Seattle's, we can simply use the percentage difference we calculated above to find the percentage by which Portland's sales were smaller:

Portland sales were 60.78% smaller than Seattle's.

c. Portland sales were ___ % of Seattle's.

To calculate the percentage of Seattle's sales that Portland's sales represent, we can use the following formula:

Percentage = (smaller value / larger value) x 100%

Percentage = 0.62195 x 100%

Substituting the values, we get:

Percentage = (255,000 / 410,000) x 100%

Percentage = 62.2%

Therefore, Portland's sales were 62.2% of Seattle's.

The mathematical expression to be evaluated is:

[tex]2 \frac{3}{6} - \frac{1}{3}[/tex]

To simplify the expression, we first convert the mixed fraction to an improper fraction:

[tex]2 \frac{3}{6} = \frac{(2 \times 6) + 3}{6} = \frac{15}{6}[/tex]

Substituting this value back into the original expression, we get:

[tex]2 \frac{3}{6} - \frac{1}{3} = \frac{15}{6} - \frac{1}{3}[/tex]

Now we need to find a common denominator for the two fractions:

[tex]\frac{15}{6} - \frac{1}{3} = \frac{15}{6} \times \frac{2}{2} - \frac{1}{3} \times \frac{2}{2} = \frac{30}{12} - \frac{2}{6}[/tex]

We can simplify the second fraction:

[tex]\frac{30}{12} - \frac{2}{6} = \frac{30}{12} - \frac{4}{12} = \frac{26}{12}[/tex]

Finally, we can simplify the fraction by dividing both the numerator and denominator by their greatest common factor, which is 2:

[tex]\frac{26}{12} = \frac{13}{6}[/tex]

Therefore, the simplified value of the mathematical expression is:

[tex]2 \frac{3}{6} - \frac{1}{3} = \frac{13}{6}[/tex]

Answer:

[tex]2\frac{1}{6}[/tex]

Step-by-step explanation:

First, write the fractions as improper fractions.

[tex]\sf2\frac{3}{6} -\frac{1}{3} \\\\\sf\frac{15}{6} -\frac{1}{3}[/tex]

To, subtract the fractions make the denominators the same.

For that, multiply both sides of 1/3 by 2.

[tex]\sf\frac{15}{6} -\frac{1*2}{3*2} \\\\\sf\frac{15}{6} -\frac{2}{6}[/tex]

Therefore, each square has a side length of 1.5 cm. The perimeter of each square is 6 cm.

Perimeter is the distance around the outside of a two-dimensional shape, such as a polygon or a circle. It is the sum of the lengths of all the sides of the shape.

Here,

To calculate the perimeter of the rectangle, we need to first convert the side lengths to the same units. 1 cm 5 mm is equal to 1.5 cm, so the rectangle has dimensions 3 cm by 1.5 cm.

The perimeter of the rectangle is then:

P = 2(3 cm) + 2(1.5 cm)

= 9 cm

To divide the rectangle into two equal squares, we need to find the side length of each square.

The area of the rectangle is:

A = (3 cm)(1.5 cm)

By using chi-squared test, we can conclude that there is evidence of an association between breed and milk yield at the 5% significance level.

What is chi-squared test?

To perform a chi-squared test for independence between breed and milk yield, we need to set up the hypotheses:

Null hypothesis: There is no association between breed and milk yield.

Alternative hypothesis: There is an association between breed and milk yield.

We will use a significance level of 0.05.

To calculate the expected counts for each cell, we will use the formula: (row total x column total) / grand total.

The observed counts and expected counts are:

The grand total is 100.

The degrees of freedom for the test are (number of rows - 1) x (number of columns - 1) = (2 - 1) x (3 - 1) = 2.

Using a chi-squared distribution table or calculator, we find the critical value for a chi-squared test with 2 degrees of freedom and a 0.05 significance level to be 5.99.

To calculate the test statistic, we use the formula:

chi-squared = [tex]sum((observed\ count - expected\ count)^2 / expected\ count)[/tex]

The calculated value of chi-squared is:

[tex]chi-squared = ((32-25.76)^2 / 25.76) + ((20-19.04)^2 / 19.04) + ((16-13.20)^2 / 13.20) + ((10-16.24)^2 / 16.24) + ((18-18.96)^2 / 18.96) + ((4-4.80)^2 / 4.80) = 10.92[/tex]

The degrees of freedom for the test are 2, and the critical value is 5.99.

Since the calculated value of chi-squared (10.92) is greater than the critical value (5.99), we reject the null hypothesis.

Therefore, we can conclude that there is evidence of an association between breed and milk yield at the 5% significance level.

Answer:

0 degrees

Step-by-step explanation:

To find m/YAI, we need to first find the measure of angle KAI, which is the sum of angles KAY and LAI. Then, we can find the measure of angle YAI by subtracting the measure of angle KAI from 180 degrees.

Using the angle addition postulate, we know that:

m/KAY + m/LAI = m/KAI

Substituting the given values, we get:

4x + 39 + 12x - 9 = m/KAI

Simplifying the expression, we get:

16x + 30 = m/KAI

Now, we need to solve for x. To do this, we can use the fact that angles KAY and LAI are supplementary (add up to 180 degrees) since they form a straight line. Thus:

m/KAY + m/LAI = 180

Substituting the given values, we get:

4x + 39 + 12x - 9 = 180

Simplifying the expression, we get:

16x + 30 = 180

Subtracting 30 from both sides, we get:

16x = 150

Dividing both sides by 16, we get:

x = 9.375

Now that we know x, we can substitute it back into the equation we found earlier:

16x + 30 = m/KAI

16(9.375) + 30 = m/KAI

150 + 30 = m/KAI

m/KAI = 180

So, we know that angle KAI measures 180 degrees. To find m/YAI, we need to subtract the measure of angle KAI from 180 degrees:

m/YAI = 180 - m/KAI

m/YAI = 180 - 180

m/YAI = 0

Therefore, we can conclude that the measure of angle YAI is 0 degrees. This means that YAI is not an angle, but a line segment, and it does not have a measure in degrees.

Therefore, the x-coordinate is 1/2.

A coordinate is a value that represents a point's position in a given system of reference. In two-dimensional (2D) space, coordinates typically consist of two values, x and y, that represent the point's position along the horizontal and vertical axes, respectively.

Given by the question.

To find the x-coordinate of the point where the terminal side intersects the unit circle, we first need to determine the quadrant in which the terminal side lies based on the angle measure of 60 degrees.

Since 60 degrees is in the first quadrant (0 to 90 degrees), the x-coordinate will be positive.

Next, we can use the fact that the terminal side intersects the unit circle, which means its distance from the origin is 1.

Since the angle measure is 60 degrees, we can construct a right triangle with the terminal side as the hypotenuse, and one leg parallel to the x-axis.

The opposite side to the angle t will be sin (60), and the adjacent side to the angle t will be cos (60).

Using the trigonometric identity cos (60) = 1/2, we can see that the x-coordinate of the point where the terminal side intersects the unit circle is: cos (60) = 1/2.

The wrestler's weight before he went on his diet was 78.0 kilograms.

What is y-intercept?

In the context of a graph of a function, the y-intercept is the point where the graph intersects the y-axis. It is the value of the dependent variable (y) when the independent variable (x) is zero. Geometrically, the y-intercept is the value of the function at the point where it crosses the y-axis.

To determine the wrestler's weight before he went on his diet, we need to find the y-intercept of the linear function that represents his weight gain over time. This is because the y-intercept corresponds to the initial weight of the wrestler, i.e., his weight before he started his diet.

We can use the two data points where the time is 0 (i.e., at the start of the diet) to find the slope of the linear function:

(1.5, 85.8) and (3.0, 93.6)

The change in weight over the time interval of 1.5 to 3.0 months is:

93.6 - 85.8 = 7.8

The change in time over that interval is:

3.0 - 1.5 = 1.5

So the slope of the linear function is:

7.8 / 1.5 = 5.2

Now we can use the point-slope form of a linear function to write an equation for the wrestler's weight gain over time:

y - 85.8 = 5.2(x - 1.5)

where y represents the wrestler's weight and x represents the time in months.

To find the wrestler's weight before he went on his diet, we need to evaluate this equation at x = 0:

y - 85.8 = 5.2(0 - 1.5)

y - 85.8 = -7.8

y = 78.0

Therefore, the wrestler's weight before he went on his diet was 78.0 kilograms.

Answer: We can use the DuPont Model to calculate the total assets turnover and equity multiplier:

ROE = ROA × Equity Multiplier

Equity Multiplier = Total Assets / Total Equity

Profit Margin = Net Income / Sales

Total Assets Turnover = Sales / Total Assets

Given:

ROA = 12%

Profit Margin = 8%

ROE = 19%

To find the Total Assets Turnover:

Profit Margin = Net Income / Sales

0.08 = Net Income / Sales

Net Income = 0.08 x Sales

ROA = 12%

ROA = Net Income / Total Assets

0.12 = 0.08 x Sales / Total Assets

Total Assets Turnover = Sales / Total Assets = 0.08 / 0.12 = 0.67

Therefore, the total assets turnover is 0.67.

To find the Equity Multiplier:

ROE = ROA x Equity Multiplier

0.19 = 0.12 x Equity Multiplier

Equity Multiplier = 0.19 / 0.12 = 1.58

Therefore, the equity multiplier is 1.58.

Note: The total assets turnover and equity multiplier are related to each other through the DuPont model. The product of these two ratios should be equal to the ROE. In this case, 0.67 x 1.58 = 1.06, which is approximately equal to 1.9 (ROE in decimal form). This confirms that our calculations are correct.

f) 0.1384 is not equal to 0.1391, which indicates that the two events are not independent

Probability is a measure of the likelihood or chance of an event occurring, expressed as a number between 0 and 1, with 0 indicating impossibility and 1 indicating certainty.

The explanation to the above probability answer are given below:

a)

From the contingency table, we can see that the total number of medium-sized fish is 96. The total number of fish in the tank is 302. Therefore, the probability of catching a medium-sized fish is:

Probability of catching a medium-sized fish = Total number of medium-sized fish / Total number of fish

Probability of catching a medium-sized fish = 96 / 302

Probability of catching a medium-sized fish = 0.3182

Therefore, the probability of catching a medium-sized fish from the tank is 0.3182

b)
From the contingency table, we can see that the total number of medium-sized guppies is 42. The total number of fish in the tank is 302. Therefore, the probability of catching a medium-sized guppy is:

Probability of catching a medium-sized guppy = Total number of medium-sized guppies / Total number of fish

Probability of catching a medium-sized guppy = 42 / 302

Probability of catching a medium-sized guppy = 0.1391

Therefore, the probability of catching a medium-sized guppy from the tank is 0.1391.

c)

From the contingency table, we can see that the number of medium-sized guppies is 42, and the number of medium-sized fish is 96. Therefore, the probability of catching a guppy if we randomly select a medium-sized fish is:

Probability of catching a guppy given a medium-sized fish = Number of medium-sized guppies / Total number of medium-sized fish

Probability of catching a guppy given a medium-sized fish = 42 / 96

Probability of catching a guppy given a medium-sized fish = 0.4375

Therefore, the probability of catching a guppy if we randomly select a medium-sized fish from the tank is 0.4375.

d)
To calculate the probability of catching a medium-sized guppy if we randomly select a guppy from the tank, we need to find the number of medium-sized guppies in the tank and divide it by the total number of guppies in the tank.

From the contingency table, we can see that the number of medium-sized guppies is 42, and the total number of guppies is 131. Therefore, the probability of catching a medium-sized guppy if we randomly select a guppy from the tank is:

Probability of catching a medium-sized guppy given a guppy = Number of medium-sized guppies / Total number of guppies

Probability of catching a medium-sized guppy given a guppy = 42 / 131

Probability of catching a medium-sized guppy given a guppy = 0.3206

Therefore, the probability of catching a medium-sized guppy if we randomly select a guppy from the tank is 0.3206.


e)

From the contingency table, we can see that the total number of non-goldfish is 190 (45 medium goldfish + 70 small guppy + 42 medium guppy + 9 medium gourami + 10 large gourami + 14 small gourami). The total number of fish in the tank is 302. Therefore, the probability of catching a fish that is not a goldfish is:

Probability of catching a fish that is not a goldfish = Total number of non-goldfish / Total number of fish

Probability of catching a fish that is not a goldfish = 190 / 302

Probability of catching a fish that is not a goldfish = 0.6291

Therefore, the probability of catching a fish that is not a goldfish if we randomly select a fish from the tank is 0.6291.

f)

From the contingency table, we can see that the probability of randomly catching a guppy is 131/302, which is approximately 0.4344. Similarly, the probability of randomly catching a medium-sized fish is 96/302, which is approximately 0.3182.

Now, let's consider the joint probability of randomly catching a medium-sized guppy, which we calculated earlier to be 42/302, or approximately 0.1391. To determine if the events are independent, we need to compare the product of the probabilities of the individual events (catching a guppy and catching a medium-sized fish) to the joint probability of the events occurring together.

If the events are independent, then the product of their individual probabilities should be equal to the joint probability:

P(catching a guppy) x P(catching a medium-sized fish)
= P(catching a medium-sized guppy)

0.4344 x 0.3182 = 0.1391

0.1384 is not equal to 0.1391, which indicates that the two events are not independent.

The coefficient for Py (10) suggests that there is a positive relationship between the price of the competing brand of fruit drink and the quantity demanded for this brand. In other words, as the price of the competing brand increases, the quantity demanded for this brand also increases.

Step-by-step explanation:

To calculate the monthly consumption of the fruit drink, we plug in the given values into the demand equation,

Qx = 10 - 5(2) + 0.001(20,000) + 10(2.5)

Qx = 10 - 10 + 20 + 25

Qx = 45 liters per family per month.

Therefore, the monthly consumption of the fruit drink per family is 45 liters.

If the median annual family income increased to $30,000, then the new monthly consumption of the fruit drink per family can be calculated as follows,

Qx = 10 - 5(2) + 0.001(30,000) + 10(2.5)

Qx = 10 - 10 + 30 + 25

Qx = 55 liters per family per month.

Therefore, the monthly consumption of the fruit drink per family would increase from 45 liters to 55 liters per family per month.

To determine the demand function, we need to solve for Qx in terms of the other variables,

Qx = 10 - 5Px + 0.001M + 10Py

Qx - 10Py = 10 - 5Px + 0.001M

Qx = (10 - 5Px + 0.001M) / 10Py

Therefore, the demand function is:

Qx = (10 - 5Px + 0.001M) / 10Py

To find the inverse demand function, we need to solve for Px in terms of Qx.

Qx = 10 - 5Px + 0.001M + 10Py

5Px = 10 - Qx - 0.001M - 10Py

Px = (10 - Qx - 0.001M - 10Py) / 5

Therefore, the inverse demand function is,

Px = (10 - Qx - 0.001M - 10Py) / 5

Answer:

Step-by-step explanation:

The BAC (Blood Alcohol Concentration) of a person depends on several factors, such as the amount of alcohol consumed, the time over which the alcohol was consumed, and the weight and gender of the person. For this problem, we will assume that the woman has a normal metabolism and that the alcohol is completely absorbed into her bloodstream.

To calculate the BAC at 8 pm, we need to know the amount of alcohol that the woman consumed and the time over which she consumed it. We are given that she had 2 mixed drinks between 7-8 pm, which contained a total of 2 ounces of liquor. We are also given that she had a glass of wine at 10 pm, but we don't need to consider this for the BAC at 8 pm.

Using the Widmark formula, we can calculate the BAC at 8 pm:

BAC = (Alcohol consumed / (Body weight x r)) - (0.015 x Hours since first drink)

where r is the gender constant (0.55 for females) and 0.015 is the rate at which the liver metabolizes alcohol.

Plugging in the values we know, we get:

BAC = (2 oz / (130 lbs x 0.55)) - (0.015 x 1 hour)

BAC = 0.0208 - 0.015

BAC = 0.0058

Therefore, the woman's BAC at 8 pm was approximately 0.0058, which is below the legal limit for driving in most states in the US.

The volume of the pyramid is V = (1/3) (3²) (5) = 45 cm³ thus the rate at which the water level is rising when the water level is 3 cm is 45 cm³/sec.

Volume is a measure of the amount of space that an object occupies or contains. It is measured in terms of cubic units, such as cubic metres or cubic centimetres. Volume is a three dimensional measure, which means it takes into account the length, width and height of an object.

The rate at which the water level is rising when the water level is 3 cm can be calculated using the formula for the volume of a pyramid. The formula for the volume of a pyramid is V = (1/3) bh², where b is the area of the base and h is the height. In this case, the base is a square with sides of length 3 cm and the height is 5 cm. Therefore, the volume of the pyramid is V = (1/3) (3²) (5) = 45 cm³.

Since the water is being filled at a constant rate of 45 cm³/sec, then the rate at which the water level is rising when the water level is 3 cm is 45 cm³/sec. This is because the water level is rising at the same rate at which the water is being filled, and since the water is being filled at a rate of 45 cm³/sec, the water level is also rising at the same rate. This is why the rate at which the water level is rising when the water level is 3 cm is 45 cm³/sec.
