Answer:

15 apples

Step-by-step explanation:

It's kinda obvious ;-;

Answer: 15 because it + so 5 + 10 = 15

Step-by-step explanation:

The order cycle length that would require the buyer to hold the most total inventory during lead time is 8 days with \(\pm\) 5 days of variation, as it has the widest range of variation, and thus, the most variability to be covered by safety stock.

The order cycle length and the variability in demand and lead time both affect the amount of inventory that a buyer needs to hold during lead time. The longer the order cycle length, the more inventory the buyer needs to hold during lead time to cover demand until the next order arrives. On the other hand, the greater the variability in demand and lead time, the more safety stock the buyer needs to hold to avoid stockouts.

We must take into account both the order cycle length and the fluctuation in demand and lead time to determine which of the mentioned order cycle lengths would need the buyer to keep the highest total inventory during lead time.

The order cycle lengths are:

10 days, \(\pm\) 4 days

10 days, \(\pm\) 2 days

9 days, \(\pm\) 3 days

8 days, \(\pm\) 5 days

The variability in demand and lead time is greater in the orders with wider ranges of variation. Therefore, we can calculate the range of variation for each order cycle length by adding the maximum variation in demand and the maximum variation in lead time:

10 days, \(\pm\) 4 days: range of variation = 4 + 4 = 8 days

10 days, \(\pm\) 2 days: range of variation = 2 + 2 = 4 days

9 days, \(\pm\) 3 days: range of variation = 3 + 3 = 6 days

8 days, \(\pm\) 5 days: range of variation = 5 + 5 = 10 days

Hence, the order cycle length with the greatest range of variation, and hence the most variability that needs to be covered by safety stock, is 8 days with \(\pm\) 5 days of fluctuation. This order cycle length would need the buyer holding the highest total inventory throughout lead time.

You should buy approximately 1.067 kilograms of apples at $10.20 per kilogram in order to have the kilogram of fruit cost $8.15.

Let's assume that Sally bought x kilograms of apples at $10.20 per kilogram.

The total cost of bananas is given as AED 7.35 per kilogram, and Sally bought 1.4 kilograms of bananas. So, the cost of the bananas is:

Cost of bananas = AED 7.35 * 1.4 = AED 10.29

The total cost of apples is given by the equation:

Cost of apples = $10.20 * x

The total cost of the fruits combined should be AED 8.15 per kilogram. So, the equation becomes:

Total cost of fruits = (Cost of bananas + Cost of apples) / (1.4 + x) = AED 8.15

Substituting the known values, we have:

(10.29 + 10.20 * x) / (1.4 + x) = 8.15

Cross-multiplying and simplifying, we get:

10.29 + 10.20 * x = 8.15 * (1.4 + x)

Expanding the equation, we have:

10.29 + 10.20 * x = 11.41 + 8.15 * x

Rearranging the equation, we get:

10.20 * x - 8.15 * x = 11.41 - 10.29

1.05 * x = 1.12

Dividing both sides by 1.05, we find:

x = 1.12 / 1.05

x ≈ 1.067

Answer:

City A and city B will have equal population 25years after 1990

Step-by-step explanation:

Given

Let

\(t \to\) years after 1990

\(A_t \to\) population function of city A

\(B_t \to\) population function of city B

City A

\(A_0 = 10000\) ---- initial population (1990)

\(r_A =3\%\) --- rate

City B

\(B_{10} = \frac{1}{2} * A_{10}\) ----- t = 10 in 2000

\(A_{20} = B_{20} * (1 + 20\%)\) ---- t = 20 in 2010

Required

When they will have the same population

Both functions follow exponential function.

So, we have:

\(A_t = A_0 * (1 + r_A)^t\)

\(B_t = B_0 * (1 + r_B)^t\)

Calculate the population of city A in 2000 (t = 10)

\(A_t = A_0 * (1 + r_A)^t\)

\(A_{10} = 10000 * (1 + 3\%)^{10}\)

\(A_{10} = 10000 * (1 + 0.03)^{10}\)

\(A_{10} = 10000 * (1.03)^{10}\)

\(A_{10} = 13439.16\)

Calculate the population of city A in 2010 (t = 20)

\(A_t = A_0 * (1 + r_A)^t\)

\(A_{20} = 10000 * (1 + 3\%)^{20}\)

\(A_{20} = 10000 * (1 + 0.03)^{20}\)

\(A_{20} = 10000 * (1.03)^{20}\)

\(A_{20} = 18061.11\)

From the question, we have:

\(B_{10} = \frac{1}{2} * A_{10}\)  and  \(A_{20} = B_{20} * (1 + 20\%)\)

\(B_{10} = \frac{1}{2} * A_{10}\)

\(B_{10} = \frac{1}{2} * 13439.16\)

\(B_{10} = 6719.58\)

\(A_{20} = B_{20} * (1 + 20\%)\)

\(18061.11 = B_{20} * (1 + 20\%)\)

\(18061.11 = B_{20} * (1 + 0.20)\)

\(18061.11 = B_{20} * (1.20)\)

Solve for B20

\(B_{20} = \frac{18061.11}{1.20}\)

\(B_{20} = 15050.93\)

\(B_{10} = 6719.58\) and \(B_{20} = 15050.93\) can be used to determine the function of city B

\(B_t = B_0 * (1 + r_B)^t\)

For: \(B_{10} = 6719.58\)

We have:

\(B_{10} = B_0 * (1 + r_B)^{10}\)

\(B_0 * (1 + r_B)^{10} = 6719.58\)

For: \(B_{20} = 15050.93\)

We have:

\(B_{20} = B_0 * (1 + r_B)^{20}\)

\(B_0 * (1 + r_B)^{20} = 15050.93\)

Divide \(B_0 * (1 + r_B)^{20} = 15050.93\) by \(B_0 * (1 + r_B)^{10} = 6719.58\)

\(\frac{B_0 * (1 + r_B)^{20}}{B_0 * (1 + r_B)^{10}} = \frac{15050.93}{6719.58}\)

\(\frac{(1 + r_B)^{20}}{(1 + r_B)^{10}} = 2.2399\)

Apply law of indices

\((1 + r_B)^{20-10} = 2.2399\)

\((1 + r_B)^{10} = 2.2399\) --- (1)

Take 10th root of both sides

\(1 + r_B = \sqrt[10]{2.2399}\)

\(1 + r_B = 1.08\)

Subtract 1 from both sides

\(r_B = 0.08\)

To calculate \(B_0\), we have:

\(B_0 * (1 + r_B)^{10} = 6719.58\)

Recall that: \((1 + r_B)^{10} = 2.2399\)

So:

\(B_0 * 2.2399 = 6719.58\)

\(B_0 = \frac{6719.58}{2.2399}\)

\(B_0 = 3000\)

Hence:

\(B_t = B_0 * (1 + r_B)^t\)

\(B_t = 3000 * (1 + 0.08)^t\)

\(B_t = 3000 * (1.08)^t\)

The question requires that we solve for t when:

\(A_t = B_t\)

Where:

\(A_t = A_0 * (1 + r_A)^t\)

\(A_t = 10000 * (1 + 3\%)^t\)

\(A_t = 10000 * (1 + 0.03)^t\)

\(A_t = 10000 * (1.03)^t\)

and

\(B_t = 3000 * (1.08)^t\)

\(A_t = B_t\) becomes

\(10000 * (1.03)^t = 3000 * (1.08)^t\)

Divide both sides by 10000

\((1.03)^t = 0.3 * (1.08)^t\)

Divide both sides by \((1.08)^t\)

\((\frac{1.03}{1.08})^t = 0.3\)

\((0.9537)^t = 0.3\)

Take natural logarithm of both sides

\(\ln(0.9537)^t = \ln(0.3)\)

Rewrite as:

\(t\cdot\ln(0.9537) = \ln(0.3)\)

Solve for t

\(t = \frac{\ln(0.3)}{ln(0.9537)}\)

\(t = 25.397\)

Approximate

\(t = 25\)

The graph of the function f(x) = x² + 2x + 3 is a parabola with vertex (-1, 2).

You can use the vertical line test on a graph to determine whether a relation is a function. If it is impossible to draw a vertical line that intersects the graph more than once, then each x-value is paired with exactly one y-value. So, the relation is a function.

Given, the function is f(x) = x² + 2x + 3

We have to find the graph of the function.

Let y = x² + 2x + 3

Put x = -3

y = (-3)² + 2(-3) + 3

= 9 - 6 + 3

= 9 - 3

y = 6

Put x = -2

y = (-2)² + 2(-2) + 3

= 4 - 4 + 3

y = 3

Put x = -1

y = (-1)² + 2(-1) + 3

= 1 - 2 + 3

= 4 - 2

y = 2

Put x = 0

y = (0)² + 2(0) + 3

= 0 + 0 + 3

y = 3

Put x = 1

y = (1)² + 2(1) + 3

= 1 + 2 + 3

= 3 + 3

y = 6

We can plot the graph using the points.

Answer:

To find the probability that the number x of correct answers is fewer than 4, we need to calculate the sum of the probabilities for x=0, x=1, x=2, and x=3, which can be written as:

P(x<4) = P(x=0) + P(x=1) + P(x=2) + P(x=3)

We can use the binomial probability formula to calculate each of these individual probabilities, with n=7 and p=0.2:

P(x=k) = (n choose k) * p^k * (1-p)^(n-k)

P(x=0) = (7 choose 0) * 0.2^0 * 0.8^7 = 0.2097

P(x=1) = (7 choose 1) * 0.2^1 * 0.8^6 = 0.3670

P(x=2) = (7 choose 2) * 0.2^2 * 0.8^5 = 0.3025

P(x=3) = (7 choose 3) * 0.2^3 * 0.8^4 = 0.1441

Therefore, the probability that the number x of correct answers is fewer than 4 is:

P(x<4) = P(x=0) + P(x=1) + P(x=2) + P(x=3)

= 0.2097 + 0.3670 + 0.3025 + 0.1441

≈ 0.9233

Rounding to four decimal places, the probability that the number x of correct answers is fewer than 4 is approximately 0.9233.

The answer of the question to find the area of the triangle is the area of the triangle is 120 cm².

Area is a measure of the amount of space inside a two-dimensional shape, like a rectangle, circle, or triangle. It is expressed in square units, like square meters, square feet, or square centimeters. The area of a shape is determined by multiplying the length of its sides, or its base and height, depending on the shape.

The area of triangle is found by multiplying its base by its height and dividing result by 2. Area is an important concept in many fields, including geometry, architecture, engineering, and physics.

If the base of the triangle is 12 cm, then we can use the expression we found for the height in terms of the base to find the height:

H = b + 8 = 12 + 8 = 20

So height of triangle is 20 cm.

Now we use formula for area of triangle:

A = 1/2 * b * H

Substituting the values we have:

A = 1/2 * 12 * 20

Simplifying:

A = 120  cm²

Therefore, the area of the triangle is 120cm².

The company can expect to receive an average return of $837.45 from selling this insurance policy.

To find the expected return for the insurance company, we need to calculate the total amount of money the company expects to receive from the policy, taking into account the probability that the policyholder will live or die within the next eight years.

If the policyholder lives for the next eight years, the company will receive the premium of $885 and will not have to pay out any death benefit. If the policyholder dies within the next eight years, the company will have to pay out the death benefit of $19,500. Since the probability that the policyholder will live for the next eight years is 0.97, the probability that the policyholder will die within the next eight years is 0.03.

Therefore, the expected return for the company is:

(0.97)($885) + (0.03)($19,500 - $885) = $837.45

The expression cos x/cot x simplifies to sin x by utilizing trigonometric identities and canceling out the common cosine terms in the numerator and denominator.

To simplify the expression cos x/cot x, we need to utilize trigonometric identities. Cotangent (cot x) is the reciprocal of the tangent function, so we can rewrite cot x as 1/tan x.

Now, substituting 1/tan x for cot x in the expression cos x/cot x, we have:

cos x / (1/tan x)

To divide by a fraction, we multiply by its reciprocal. Therefore, multiplying cos x by tan x, we get:

(cos x)(tan x)

Using the identity tan x = sin x / cos x, we can substitute sin x / cos x for tan x:

(cos x)(sin x / cos x)

The cos x term in the numerator and denominator cancels out, leaving us with:

sin x

Therefore, the simplified expression for cos x / cot x is sin x.
