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.

Answer:

Parameter estimates

The coefficient for Px (-5) suggests that there is an inverse relationship between the price of the fruit drink and the quantity demanded. In other words, as the price of the drink increases, the quantity demanded decreases.

The coefficient for M (0.001) suggests that there is a positive relationship between the median annual family income and the quantity demanded. In other words, as the median income increases, the quantity demanded also increases.

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

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 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.

Isosceles triangle is the shape which has exactly one line of symmetry.

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.

Therefore, the estimated length of the diagonal is approximately 1.414 units.

The square root of a number is a value that, when multiplied by itself, gives the original number. In other words, the square root of a number "x" is a value "y" such that y multiplied by y equals x. The symbol for square root is √.

For example, the square root of 25 is 5, because 5 multiplied by 5 equals 25. Similarly, the square root of 64 is 8, because 8 multiplied by 8 equals 64. The square root of a negative number is not a real number, as there is no real number that, when squared, equals a negative number.

Using the Pythagorean theorem, we can find the length of the diagonal of the square.

If we draw a diagonal from one corner of the square to the opposite corner, we create a right triangle. The two legs of the right triangle are the sides of the square, which have a length of 1. The hypotenuse, which is the diagonal of the square, is the side we are trying to find.

Using the Pythagorean theorem, we can write:

[tex]d^2 = 1^2 + 1^2[/tex]

where d is the length of the diagonal.

Simplifying, we get:

[tex]d^2 = 2[/tex]

Taking the square root of both sides, we get:

The quadratic function for the given graph is f(x) = -(x - 0.2)² + 6.2.

What is a quadratic function?

A polynomial function with one or more variables, where the largest exponent of the variable is two, is referred to as a quadratic function. It is also known as the polynomial of degree 2 since the greatest degree term in a quadratic function is of second degree.

The graph crosses the y-axis at 6 so the graph has a y-intercept at (0,6).

The highest point in the graph is at (0.2,6.2) and the highest point is the maximum.

The graph crosses the x-axis at 2 and -1.5 so the graph has an x-intercept at (2,-1.5).

The graph's line of symmetry is x = 0.2 since the vertex is (0.2,6.2).

The zeros of a graph are its x-intercept so the graph has zeroes of 2 and -1.5.

The quadratic function is of the form a(x - h)² + k where (h, k) is the vertex.

Since, the graph is opening downwards so the value of a = -1 < 0.

The function f(x) = -(x - 0.2)² + 6.2 is the quadratic function of the graph.

The system of inequalities associated with the graph is y ≥ 2 and x < 3.

The system of inequalities associated with the graph can be determined by examining the shaded region on the graph. The shaded region represents all the possible solutions that satisfy the given inequalities. To determine the system of inequalities, we need to consider the boundaries of the shaded region. These boundaries are formed by the lines or curves on the graph.

1. Identify the lines or curves that form the boundaries of the shaded region. These lines or curves are usually represented by equations or inequalities. For example, if there is a solid line, it indicates that the boundary is included in the solution. If there is a dashed line, it indicates that the boundary is not included in the solution.

2. Determine the inequalities associated with each boundary line or curve. You can do this by examining the direction of the inequality symbol (<, >, ≤, or ≥) and the location of the line or curve in relation to the shaded region.

3. Write down the inequalities associated with each boundary line or curve. Make sure to include the correct inequality symbol and any necessary constants or variables.

4. Combine all the inequalities together to form the system of inequalities. This can be done by using logical operators such as "and" or "or" to connect the individual inequalities. The "and" operator is used when all the inequalities must be satisfied simultaneously, while the "or" operator is used when at least one of the inequalities must be satisfied. For example, let's say the graph has a solid horizontal line at y = 2, a dashed vertical line at x = 3, and the shaded region is above the horizontal line and to the left of the vertical line. In this case, the system of inequalities would be: - y ≥ 2 (since the shaded region is above the line) - x < 3 (since the shaded region is to the left of the line) Therefore, the system of inequalities associated with the graph is y ≥ 2 and x < 3.

The perimeter of the figure is approximately 63.6 meters, since the lengths of all the sides add up to the figure's perimeter.

Perimeter is the total length of the boundary of a closed 2-dimensional shape. In other words, it is the distance around the edge of a shape. The perimeter is usually measured in units such as meters, centimeters, feet, or inches depending on the measurement system used. The perimeter can be calculated by adding up the lengths of all the sides of the shape.

Since opposite sides of a parallelogram are equal in length, the length of the straight side of the first parallelogram is:

Length of first parallelogram = 9m

Similarly, the length of the straight side of the second parallelogram is:

Length of second parallelogram = 11m

Now, let's find the length of the straight side of the semicircle segment. We are given that the other side of each parallelogram gets half of the diameter, which is 17m. Therefore, the length of the straight side of the semicircle segment is:

Length of semicircle segment = 17m / 2 = 8.5m

The lengths of all the sides add up to the figure's perimeter. Let's use P to represent the perimeter. Then:

P = 2 (parallelogram length) + semicircle length

When we replace the values we discovered earlier, we obtain:

P = 2(9m + 11m) + π(17m)/2
