The required answer is the annual cost saved by shifting from the 500-bag lot size to the EOQ is $1,059.92.

Explanation:-

a. Economic order quantity (EOQ) is defined as the optimal quantity of inventory to be ordered each time to reduce the total annual inventory costs.

It is calculated as follows: EOQ = sqrt(2DS/H)

Where, D = Annual demand = 100 x 52 = 5200S = Order cost = $57 per order H = Annual holding cost = 0.30 x 10.75 = $3.23 per bag per year .Therefore, EOQ = sqrt(2 x 5200 x 57 / 3.23) = 234 bags. The average time between orders (TBO) can be calculated using the formula: TBO = EOQ / D = 234 / 100 = 2.34 weeks ≈ 2 weeks (rounded to nearest whole number).

Hence, the EOQ is 234 bags and the average time between orders is 2 weeks (approx).b. R is the reorder point, which is the inventory level at which an order should be placed to avoid a stockout.

It can be calculated using the formula:R = dL + zσL

Where,d = Demand per day = 100 / 5 = 20L = Lead time = 1 week (5 working days) = 5 day

z = z-value for 92% cycle-service level = 1.75 (from standard normal table)σL = Standard deviation of lead time demand = σ / sqrt(L) = 16 / sqrt(5) = 7.14 (approx)

Therefore,R = 20 x 5 + 1.75 x 7.14 = 119.2 ≈ 120 bags

Hence, the reorder point R should be 120 bags.c. An inventory withdraw of 10 bags was just made. Is it time to reorder?The current inventory level is 310 bags, which is greater than the reorder point of 120 bags. Since there are no open orders or backorders, it is not time to reorder.d. The store currently uses a lot size of 500 bags (i.e., Q = 500).What is the annual holding cost of this policy.

Annual ordering cost. Without calculating the EOQ, how can you conclude the lot size is too large?Annual ordering cost = (D / Q) x S = (5200 / 500) x 57 = $592.80 per year.

Annual holding cost = Q / 2 x H = 500 / 2 x 0.30 x 10.75 = $806.25 per year. Total annual inventory cost = Annual ordering cost + Annual holding cost= $592.80 + $806.25 = $1,399.05Without calculating the EOQ, we can conclude that the lot size is too large if the annual holding cost exceeds the annual ordering cost.

In this case, the annual holding cost of $806.25 is greater than the annual ordering cost of $592.80, indicating that the lot size of 500 bags is too large.e.

The annual cost saved by shifting from the 500-bag lot size to the EOQ can be calculated as follows:Total cost at Q = 500 bags = $1,399.05Total cost at Q = EOQ = Annual ordering cost + Annual holding cost= (D / EOQ) x S + EOQ / 2 x H= (5200 / 234) x 57 + 234 / 2 x 0.30 x 10.75= $245.45 + $93.68= $339.13

Annual cost saved = Total cost at Q = 500 bags - Total cost at Q = EOQ= $1,399.05 - $339.13= $1,059.92

Hence, the annual cost saved by shifting from the 500-bag lot size to the EOQ is $1,059.92.

The equation of the tangent line to the graph of y = (x³ - 25x)^14 at the point (5,0) is y = -75x + 375.

To find the equation of the tangent line, we need to determine the slope of the tangent line at the given point (5,0). The slope of a tangent line can be found by taking the derivative of the function with respect to x and evaluating it at the point of tangency.

First, let's find the derivative of y = (x³ - 25x)^14. Using the chain rule, we have:

dy/dx = 14(x³ - 25x)^13 * (3x² - 25)

Next, we substitute x = 5 into the derivative to find the slope at the point (5,0):

m = dy/dx |(x=5) = 14(5³ - 25(5))^13 * (3(5)² - 25) = -75

Now that we have the slope, we can use the point-slope form of a line to determine the equation of the tangent line. The point-slope form is given by y - y₁ = m(x - x₁), where (x₁, y₁) is the point of tangency and m is the slope. Plugging in the values (x₁, y₁) = (5,0) and m = -75, we get:

y - 0 = -75(x - 5)

y = -75x + 375

Thus, the equation of the tangent line to the graph of y = (x³ - 25x)^14 at the point (5,0) is y = -75x + 375.

Let f(x) = 3x + 4 and g(x) = 5x² + 3x. After simplifying, (fog)(x) = (gof)(x) = 15x² + 9x + 4

The composition of functions f(x) and g(x) is given by (fog)(x) = f(g(x)) and (gof)(x) = g(f(x)). Given that f(x) = 3x + 4 and g(x) = 5x² + 3x, we can find (fog)(x) by substituting g(x) into f(x): (fog)(x) = f(g(x)) = f(5x² + 3x) = 3(5x² + 3x) + 4 = 15x² + 9x + 4.

Similarly, we can find (gof)(x) by substituting f(x) into g(x): (gof)(x) = g(f(x)) = g(3x + 4) = 5(3x + 4)² + 3(3x + 4) = 45x² + 78x + 47. Therefore, after simplifying, (fog)(x) = (gof)(x) = 15x² + 9x + 4

The height of the rectangular prism with a volume of 132.5cm³ and a base area of 25cm² is 5.3cm.

To find the height of the rectangular prism, we can use the formula for the volume of a rectangular prism, which is V = lwh (where l is the length, w is the width, and h is the height).

We are given that the volume is 132.5cm³ and the base area is 25cm². We can use the base area to find the length and width of the prism.

Since the base area is lw = 25cm², we can choose any two factors of 25 to be the length and width. Let's say the length is 5cm and the width is 5cm.

Now we can use the formula for the volume to find the height:

V = lwh
132.5cm³ = (5cm)(5cm)(h)
132.5cm³ = 25cm²(h)
h = 132.5cm³/25cm²
h = 5.3cm

The machine's expected remaining lifetime can be found using the concept of conditional probability. Specifically, we want to find the expected value of the remaining lifetime given that the machine has already been in use for 2 hours.

To find this expected value, we can use the formula:

E(X | X > 2) = ∫x*f(x | X > 2)dx

where f(x | X > 2) is the conditional probability density function of X given that X > 2.

Using Bayes' theorem, we can find that f(x | X > 2) = f(x) / P(X > 2), where P(X > 2) is the probability that X is greater than 2.

Evaluating the integral, we get:

E(X | X > 2) = ∫x*f(x) / P(X > 2) dx, with the limits of integration from 2 to infinity.

Solving for P(X > 2), we get:

P(X > 2) = ∫2 to infinity f(x) dx

Substituting the given density function into the equation, we get:

P(X > 2) = ∫2 to infinity 0.5 exp(-0.5x) dx

Solving the integral, we get:

P(X > 2) = 0.1353

Now we can use this value to solve for the expected remaining lifetime:

E(X | X > 2) = ∫2 to infinity x*f(x) / P(X > 2) dx

Solving the integral, we get:

E(X | X > 2) = 9.26 hours

Therefore, if the machine has been in use for 2 hours, we can expect it to last an additional 9.26 hours on average.

Since the rectangle is made up of 2 congruent trapezoids, we can find the length and width of the rectangle by combining the lengths and widths of the trapezoids.

First, let's find the length of the rectangle:

The length of each trapezoid is the average of its bases:

length = (11 + 8) / 2 = 9.5

Since the trapezoids are congruent, the length of the rectangle is twice the length of a trapezoid:

length of rectangle = 2 * 9.5 = 19

Next, let's find the width of the rectangle:

The height of the trapezoids is the same as the height of the rectangle:

height = 6

The width of the rectangle is the same as the width of a trapezoid. To find the width of a trapezoid, we need to use the Pythagorean theorem, since the trapezoid has a height of 6 and bases of 11 and 8:

width = sqrt(6^2 + ((11-8)/2)^2) = sqrt(36 + 0.75) = sqrt(36.75)

So, the width of the rectangle is:

width = sqrt(36.75)

Finally, let's find the area of the rectangle:

area = length * width = 19 * sqrt(36.75) ≈ 87.83

Therefore, the length of the rectangle is 19 units, the width is approximately 6.07 units, and the area is approximately 87.83 square units.

Since A and B are mutually exclusive, the probability of A occurring given that B has already occurred is 0. This means that P(A | B) = 0.

P(A ∩ B) = 0, since the events are mutually exclusive.

P(A | B) = 0, since the probability of A given B is 0 when A and B are mutually exclusive.

Since A and B are mutually exclusive, they cannot both occur at the same time. This means that the probability of them both happening at the same time is 0. As a result, P(A ∩ B) = 0.

The portfolio's return can be calculated by multiplying the weights of each investment by their respective returns and summing them up. However, without information on the weights of the investments, the portfolio's return cannot be determined accurately.

To calculate the portfolio's return, we need to know the weights of each investment, which represent the proportion of the total portfolio value allocated to each asset. Without this information, we cannot determine the exact portfolio return.

However, if we assume equal weights for simplicity, the average return of the portfolio can be estimated. In this case, the portfolio consists of $1,000 invested in Disney with a 15% return and $5,000 invested in Oracle with an 18% return.

Using equal weights, the estimated portfolio return can be calculated as follows:

Portfolio return = (Weight of Disney × Return of Disney) + (Weight of Oracle × Return of Oracle)

Assuming equal weights, the portfolio return would be:

(0.5 × 15%) + (0.5 × 18%) = 7.5% + 9% = 16.5%

Answer: A) intercepts: zero profit; maximum: maximum profit. increasing: x < 4; decreasing x > 4

 B) average slope: ≈50, about $50 increased profit for each $1 increase in price.

Step-by-step explanation:

A) The vertical axis of the graph represents profit, so the x-intercepts represent prices that produce zero profit. The maximum value of the graph is the maximum profit that can be obtained for any price.

The function is increasing for all prices below the one producing maximum profit (x < 4). The function is decreasing for all prices above the one producing maximum profit (x > 4). Obviously profit is increasing with price for x < 4, and is decreasing with price for x > 4.

__

B) We read the value of f(1) from the graph to be about 120, so the average rate of change is about ...

 (f(4) -f(1))/(4 -1) = (270 -120)/(3) = 50

The average rate of change from x=1 to x=4 is about 50.* This means profit will increase on average $50 for each $1 increase in price in that interval.

_____

* If we take the peak profit to be $270, we can write f(x) as ...
