The required rate to consume the apple by ant farm is 6 and it consume 3 apples in 18 days

A rate is an extraordinary proportion where the two terms are in various units. For instance, in the event that a 12-ounce jar of corn costs 69¢, the rate is 69¢ for 12 ounces. This isn't a proportion of two like units, like shirts. This is a proportion of two not at all like units: pennies and ounces.

We have,

Ant farm takes 3 days to consume 1/2 of an apple

To find; How much time will it take to consume 3 apples.

So, In 1 apples it consumes 6 days

For three apples = 3(6) = 18 days

Thus, Ant farm takes 18 days to consume 3 apples.

Answer:

b = b2-4ac

= (-7ab)^2 -4 (6a^2)(-3b^2)

= 49a^2b^2 + 72a^2b^2

= 121a^2b^2

Now, x = (7ab +- root 121a^2b^2)÷2(6a²)

y = 4x - 3

The price vectors a. p₁ = 3 and p₂ = 2, Mary will consume only good 1.

Here we have the Utility function as

U(x₁ , x₂) = 3x₁ + x₂

From the given utility function we can clearly see that these goods are substitutes for each other

Now,

δU/δx₁ = 3

δU/δx₂ = 1

Hence we get the Marginal Rate of Substitution or MRS

\(=- \frac{\delta U/ \delta x_1 }{\delta U/ \delta x_2}\)

= -3

The MRS signifies that for every additional unit of 1, Mary is willing to give up 3 units of good 2

|MRS| = 3

For Mary to only consume good 1, |MRS| > p₁/p₂

Hence here we get the p/p ratio for the 4 price vectors to be

a. 3/2 = 1.5

b. 10/3 = 3.33

c. 4

d. 15.4 = 3.75

Hence we can clearly say that for the price vectors p₁ = 3 and p₂ = 2, Mary will consume only good 1.

The probability that the secretary will receive 6 calls next hour is approximately 0.090 or 9.0%.

The Poisson distribution is a probability distribution that describes the number of events occurring in a fixed time interval, given the average rate at which events occur and the independence of events. In this case, the average rate of calls is 3 calls per hour.

The probability of receiving exactly 6 calls next hour can be calculated using the Poisson probability formula:

\(P(X = 6) = (e^(-λ) * λ^6) / 6!\)

where λ is the average rate of calls, e is the base of the natural logarithm, and 6! is the factorial of 6.

Substituting the values, we get:

\(P(X = 6) = (e^(-3) * 3^6) / 6! ≈ 0.090\)

Given that the second student chosen is a girl, the probability that both students are female is 0.175.

The occurrence of likely events is referred to as probability. It is the branch of mathematics concerned with numerical estimates of the likelihood of an event occurring or a statement being true.

Probability is nothing but likelihood of something is to occur. When we are unsure about the outcome of an event, we can discuss the probabilities of certain outcomes—how likely they are.

The probability of selecting a girl from the class is

\(= \frac{Number\ of\ girls}{ Total\ number\ of\ students}= \frac{14}{26}\\\\= \frac{7}{13}\)

It is known that the one of the chosen student from 2 students is girl, the probability of having both girls will be:

Capacity of a cylinder is seen as its volume

Volume of a cylinder = πr²h

The heights of the cylinders are

a. 3cm

b. 9cm

c. 5cm

Let's find the radius

Capacity = 3. 142 × r² × 3

725 = 3. 142 × r² × 3

r² = \(\frac{725}{3. 142 * 3}\)

r² = \(\frac{725}{9. 426}\)

r² = 76. 91

r = √76. 91

r = 8. 77cm

Radius of the cylinders = 8. 77cm

For cylinder with height of 9cm

Capacitance = πr²h

Capacitance = 3. 142 × 8. 77 × 8. 77 × 9

Capacitance = 2174. 94 cm³

For cylinder with height of 5cm

Capacitance = 3. 142 × 8. 77 × 8. 77 × 5

The measure of the inscribed Angle ACB is (31/360) × πr

Inscribed angles and central angles are two different kinds of angles in a circle. Both angles share the same vertex and endpoints, but their position differs.

Inscribed angles are the angles formed from two intersecting chords in a circle, whereas central angles are the angles whose vertex is the center of the circle and whose endpoints lie on the circle. These two kinds of angles have a special relationship, which can be explained using the Central Angle Theorem.

Let's look at how to use the Central Angle Theorem to solve this problem. Here is the diagram of the given problem: Inscribed Angle and Central Angle

The Central Angle Theorem states that the measure of a central angle is twice the measure of its corresponding inscribed angle. It means that if you know the measure of a central angle, you can find the measure of the inscribed angle. The inscribed angle and the central angle both have the same intercepted arc, so the measure of the inscribed angle is half the measure of the intercepted arc.

To find the measure of the inscribed angle ACB, we need to find the measure of the intercepted arc AB first. Using the formula for finding the measure of an arc, which is: measure of arc = (central angle/360) × 2πrWe can find the measure of the intercepted arc AB as follows:

measure of arc AB = (62/360) × 2πr Note that we don't know the radius of the circle, so we can't find the exact measure of the arc. However, we don't need to know the exact measure of the arc to find the measure of the inscribed angle. We only need to know that the measure of the arc is twice the measure of the inscribed angle ACB. Therefore, we can write: measure of inscribed angle ACB = (1/2) × (measure of arc AB)measure of inscribed angle ACB = (1/2) × (62/360) × 2πrSimplifying this expression, we get: measure of inscribed angle ACB = (31/360) × πr

Hence, the measure of the inscribed angle ACB is (31/360) × πr.

Therefore , the solution of the given problem of standard deviation comes out to be the CEO is informed that the mean scores for Cities A and B are identical.

Variance is a measure of difference used in statistics. The typical variance here between dataset and the mean is calculated using the multiplier of that figure. By comparing each figure to the mean, it incorporates those data points into its calculations, unlike other measurable measures of variability. Variations may result from internal or external factors and may include unintentional errors, inflated expectations, and changing economic or commercial circumstances.

Here,

It is clear that both offices share a comparable average score from the sentence "The CEO is informed that both City A or City B have the same mean score."

If City A is more reliable than City B, then City A will have a lower standard deviation.

A collection of data's variability or dispersion is measured by the standard deviation. The closer the data points are to the mean, the lower the standard deviation, and the less variable the data are.

So, the appropriate answer is:

The CEO is informed that the mean scores for Cities A and B are identical. However, due to the fact that City A's standard deviation is lower than City B's, City A is more reliable than City B.

In Chapter 6, Problem 10P, the constraints are derived based on the given problem scenario and the objective of the optimization problem. Without specific details about Problem 10P in Chapter 6, it is challenging to provide a precise explanation.

However, I can provide a general understanding of how constraints are typically formulated in optimization problems. In optimization problems, constraints are used to represent the limitations or restrictions on the decision variables. These constraints can arise from various sources, such as physical constraints, resource constraints, budget constraints, or technical constraints. To derive the constraints, you need to carefully analyze the problem statement and identify the conditions or limitations that must be satisfied. These conditions are then translated into mathematical inequalities or equations that relate the decision variables. For example, if the problem involves allocating limited resources among different activities, the constraints would represent the availability of those resources and ensure that the total allocation does not exceed the available amount. Similarly, if the problem involves production planning, constraints might include demand requirements, capacity limitations, or inventory constraints. In general, the process of formulating constraints requires careful consideration of the problem's requirements, objectives, and limitations. It often involves translating real-world constraints into mathematical expressions to create a well-defined optimization problem that can be solved using appropriate techniques.
