Part 1: Kate should buy 100 coats to maximize profits.Part 2: The probability that the coats sell out is 0.25 (25%), and the probability that they do not sell out is 0.75 (75%).

To maximize profits, Kate should consider the scenario where she sells all the coats without any left over at the end of the season.

Since the sales are uniformly distributed between 100 and 400, buying 100 coats ensures that she meets the minimum expected sales of 100. Purchasing more than 100 coats would increase costs without a guarantee of higher sales, potentially leading to excess inventory and lower profits.

Given that the sales are uniformly distributed between 100 and 400 coats, Kate's purchase of 100 coats covers the minimum expected sales.

The probability of selling out can be calculated by finding the proportion of the range covered by the desired sales (100 out of 300). Therefore, the probability of selling out is 100/300 = 0.25 or 25%. The probability of not selling out is the complement, which is 1 - 0.25 = 0.75 or 75%.

The expression which shows the total cost is 2.50+0.4x and the cost of riding 20 miles is $10.50.

Given a taxi charges $2.50 for the first mile and $0.40 for each mile

We are required to make an expression showing total cost and total cost of a 20 mile ride.

let the miles ride by tax be x.

Total cost of the product or service=Number of units*price of one units.

We have been given that $2.50 is fixed so we will not multiply our variable charge with $2.50 and multiply 0.40 with x.

So,the expression showing looks like 2.50+0.40x.

Now to find the cost when taxi travels 20 miles, we have to put x=20,

Cost=2.50+0.40*20

=2.50+(40*20)/100

=2.50+800/100

=2.50+8

=$10.50

Hence the expression which shows the total cost is 2.50+0.4x and the cost of riding 20 miles is $10.50.

This is a problem of cost behaviour pattern and depreciation cost.

1. For annual depreciation of equipment computed by the machine-hours method, choose the graph that shows a variable cost behaviour pattern, as the depreciation cost increases with the number of machine-hours.

2. For the electricity bill, choose the graph that depicts a step-variable cost behavior pattern, where there is a fixed charge followed by a variable cost that varies proportionately with the units produced.

3. For the city water bill, choose the graph that shows a step-variable cost behavior pattern, as the cost per gallon increases at different levels of water usage.

4. For the cost of direct materials with decreasing costs per unit, choose the graph that shows a declining variable cost behavior pattern, as the cost per unit decreases with each additional pound of material used.

5. For annual depreciation of equipment computed by the straight-line method, choose the graph that represents a fixed cost behavior pattern, as the depreciation cost remains constant regardless of the units produced.

6. For rent on a manufacturing plant with a fixed-fee payment, choose the graph that shows a fixed cost behavior pattern, as the rent remains the same regardless of the units produced.

7. For salaries of repair personnel, choose the graph that depicts a step-fixed cost behavior pattern, as the number of personnel required increases with every 1,000 machine-hours.

8. For the cost of direct materials without quantity discounts, choose the graph that represents a variable cost behavior pattern, as the cost increases proportionately with the units produced.

9. For rent on a manufacturing plant donated by the county with rent reduction conditions, choose the graph that shows a mixed cost behaviour pattern, as there is a minimum fixed rent and a variable rent reduction component based on labor-hours worked.

Now you will find the balance sheet induced from the calculations of cost behaviour pattern and depreciation cost.

(-8, 7); x + y = 13 → y= -x + 13

parallel lines have the same slope. slope is -1

y = -x + b

7 = -(-8) + b

7 = 8 + b

b = -1

(a) y = -x - 1

perpendicular lines have opposite slopes. slope is 1/2.

The vector field f(x,y) = 33x^2y^2i + 22x^3yj is conservative, and its potential function is φ(x,y) = 11x^3y^2 + 11x^2y^2 + C.

To determine if a vector field is conservative, we need to check if it is the gradient of a scalar function (i.e., a potential function). We can do this by taking the partial derivatives of each component with respect to their respective variables and checking if they are equal:

∂f_x/∂y = 66xy^2
∂f_y/∂x = 66xy^2

Since these partial derivatives are equal, the vector field is conservative. We can then find a potential function by integrating each component with respect to their respective variable:

φ(x,y) = 11x^3y^2 + 11x^2y^2 + C

where C is the constant of integration.

Therefore, the vector field f(x,y) = 33x^2y^2i + 22x^3yj is conservative, and its potential function is φ(x,y) = 11x^3y^2 + 11x^2y^2 + C.

The subspaces of R^3x3 are: B. The invertible 3x3 matrices, C. The 3x3 matrices with all zeros in the third row, D. The diagonal 3x3 matrices, and F. The 3x3 matrices of rank 1.

A subspace of R^3x3 is a subset that satisfies three conditions: it contains the zero matrix, it is closed under matrix addition, and it is closed under scalar multiplication.

B. The invertible 3x3 matrices form a subspace because the zero matrix is invertible and any linear combination or product of invertible matrices is also invertible.

C. The 3x3 matrices with all zeros in the third row form a subspace. Adding two matrices with all zeros in the third row results in a matrix with all zeros in the third row, and multiplying a matrix with all zeros in the third row by a scalar also yields a matrix with all zeros in the third row.

D. The diagonal 3x3 matrices form a subspace because the sum of two diagonal matrices is still a diagonal matrix, and scaling a diagonal matrix by a scalar preserves its diagonal structure.

E. The 3x3 matrices with a specific trace value do not form a subspace because the sum of two matrices with different trace values will generally not have the same trace.

F. The 3x3 matrices of rank 1 do form a subspace. The zero matrix is of rank 0, and any linear combination of rank 1 matrices will also have rank 1. Furthermore, scaling a rank 1 matrix by a scalar preserves its rank.

one leg of a right triangle is 6 inches longer than the other leg, and the hypotenuse is 30 inches. Thus,

The lengths of the legs of the triangle are 18 inches,24 inches and  30 inches.

Three vertices make up a triangle, a three-sided polygon. The angles of the triangle are formed by the connection of the three sides end to end at a point. The triangle's three angles add up to 180 degrees in total.

Given that,

one leg of a right triangle is 6 inches longer than the other leg.

hypotenuse is 30 inches.

Let assume, the other leg be x

It is given that, one leg of a right triangle is 6 inches longer than the other leg. So, One leg = x + 6

Since it is a right angled triangle,

h² = p² + b²

Where, h = hypotenuse

p = perpendicular

B = Base

So, (30)² = (x+6)² + x²

or, x = -24, 18

As, the length of side cannot be negative so x becomes 18.

Thus, x + 6 = 18 + 6 = 24 inches

Hypotenuse = 30 inches

Hence, the lengths of the legs of the triangle are 18 inches, 24 inches and  30 inches.

Given the concentric circles with center C and with m< = 75, where the inner circle has a radius of 14 yards and each circle has a radius 14 yards greater than the previous circle, we can calculate the radius of the outermost circle.

To do this, we can use the formula for the circumference of a circle, C = 2πr, where r is the radius of the circle. We know that the circumference of each circle is less than or equal to 75 yards, so we can set up the inequality:

2πr <= 75

Solving for r, we get:

r <= 75/(2π)

Using a calculator, we find that r is approximately 11.9 yards.

Therefore, the outermost circle has a radius of approximately 26.9 yards (14 + 12.9).

In summary, the concentric circles with center C have radii that increase by 14 yards from the inner circle to the outermost circle. The maximum circumference of each circle is 75 yards, and the outermost circle has a radius of approximately 26.9 yards.

Step-by-step explanation:

I believe they want the temperature at 11, so we would use the variable t to represent that. Then, we need the sum of that temperature and 8 degrees to break the record of 82 degrees, so we would do t, the temperature, added to 8 degrees, which will break the record of 82 :)

In a repeated-measures ANOVA, the variability within treatments is divided into two components: between subjects and error .(A)

To explain further, a repeated-measures ANOVA is used to analyze the differences in means of scores for the same subjects under different conditions.

The variability within treatments can be broken down into two components: 1) between subjects, which accounts for individual differences in subjects and 2) error, which represents unexplained variance that is not accounted for by between subjects or treatment effects.

By separating the variability into these two components, researchers can better understand the sources of variation and isolate the true effects of the treatments being studied.(A)

The formula for the volume of a cylinder is given by:

V = πr^2h

where V is the volume, r is the radius of the circular base, and h is the height of the cylinder.

We can find the radius of the cylinder by dividing the diameter by 2. So, the radius is:

r = d/2 = 2 feet/2 = 1 foot

Substituting the values of the radius and height into the formula, we get:

V = π(1 foot)^2(5 feet) = 15.71 cubic feet (rounded to two decimal places)

Therefore, the measurement that is closest to the volume of the cylinder in cubic feet is 15.71 cubic feet.

It takes about 1.5 seconds for the ball to hit the ground.

To find how long it takes for the ball to hit the ground, we need to find the value of x when h(x) = 0, since the height of the ball is 0 when it hits the ground. We can set -16x²+36 = 0 and solve for x:

-16x²+ 36 = 0

Dividing both sides by -16:

x² - 2.25 = 0

Adding 2.25 to both sides:

x²= 2.25

Taking the square root of both sides (we can ignore the negative root since time cannot be negative):

x = √(2.25) ≈ 1.5

Therefore, it takes about 1.5 seconds for the ball to hit the ground.
