The probability of winning the Exacta bet if you pick the horses at random is given by P ( A ) = 0.26 %

Given data ,

The Kentucky Derby had 20 horses running in the race in 2016. The number of ways to pick the first horse is 20, as any of the 20 horses could finish in the first spot. Once the first horse is picked, there are 19 remaining horses that could finish in the second spot.

Therefore, the total number of outcomes for two horses finishing in the first two spots (i.e., the Exacta bet) is 20 multiplied by 19, which is 380.

Since there is only one winning Exacta combination out of the 380 possible outcomes, the probability of winning the Exacta bet by randomly picking two horses is 1/380, which is approximately 0.0026, or 0.26%.

Hence , the probability is 0.26 %

The maximum profit is given as $31,310

a. In order to determine the intervals in which profitability P increases and decreases, we need to analyze the first derivative of its respective function, P(x).

Given the profit equation: P(x) = 2.36x - (x^2 / 25000) - 3500, the process begins by articulating its derivative, P'(x):

P'(x) = d(2.36x) - d(x^2 / 25000) - d(3500)

P'(x) = 2.36 - (2x / 25000)

P'(x) = 2.36 - x / 12500

Seeing that P'(x) > 0 implies a rising P while P'(x) < 0 portrays a decreasing P, those values must be determined. Subsequently, the critical points may be found by setting P'(x) = 0:

2.36 - x / 12500 = 0

x / 12500 = 2.36

x = 2.36 * 12500

x = 29500

To adequately evaluate the intervals (0, 29500) and (29500, 50000), we must gauge whether P'(x) is positive or negative:

For x greater than zero & less than 29500:

P'(x) = 2.36 - x / 12500 > 0

For x higher than 29500 but falling beneath 50000:

P'(x) = 2.36 - x / 12500 < 0

Hence, P is augmented on the interval from 0 until 29500, whereas it diminishes from 29500 to 50000.

b. Differentiate again the profit function we get

P'(x)= -1/12,500 <0

Therefore the profit will be maximum.

Hence 29500 bags of popcorn must cinema sell in order to maximize profit.

Answer:

[tex]\bold{f(x) = 375(2.5)^{-x}+ 33}[/tex]

Step-by-step explanation:

An exponential function of form f(x) = ba^(-x) + c has a horizontal asymptote of y = c as x approaches infinity, and a y-intercept of (0, b + c). We can use the given information to set up a system of equations and solve for the unknowns.

The horizontal asymptote is given as y = 33, so we have:

c = 33

The y-intercept is given as (0, 408), so we have:

b + c = 408

Substituting c = 33, we get:

b + 33 = 408

b = 375

So the function we're looking for is of the form:

[tex]\bold{f(x) = 375a^{-x}+ 33}[/tex]

To find a, we use the fact that the function passes through P(2, 93):

93 = 375a^(-2) + 33

60 = 375a^(-2)

a^2 = 375/60

a^2 = 6.25

a = [tex]\sqrt{6.25 } =2.5[/tex]

Therefore, the exponential function that satisfies the given conditions is:

[tex]\bold{f(x) = 375(2.5)^{-x}+ 33}[/tex]

Step-by-step explanation:

The factory produces one box of potato chips every 4 minutes, which means in one minute, it produces 1/4 boxes.

So, in 20 minutes, the factory would produce:

(1/4) x 20 = 5 boxes

Therefore, the factory would make 5 boxes filled with potato chips in 20 minutes.

Note that where the above conditions are given, the probability of A ∩ B is 1/20 and the probability of the union of A  and B P( A∪B) = 2/5. See the explanation below.

We are given that A and B are events that are independent, P(A∩B), we can rightly state that:

P(A∩B ) = P(A) x P (B)

(1/5) x  (1/4)
= 1/20

For P(A∪B)
⇒ P( A ∪B) = P (A ) + P(B) - P(A ∩B)

We can substitute the probabilities to derive:

P(A∪B)  = (1/5) + (1/4) - (120)

We can write the above as:

⇒ 4/20 + 5/20 - 1/20
= 8/20

Simplifying , we get:

P(A∪B)  = 2/5

Hence it is correct to state that the P(A ∩ B) = 1/20, while P(A∪B) = 2/5.

It is essential to determine accuracy to ensure that the collected data is reliable and can be used to make informed decisions.

How to solve the question?

Data collection is an essential aspect of research and analysis, as it involves gathering information from various sources to make informed decisions. Inaccurate data can lead to incorrect conclusions and flawed decision-making, which can have significant consequences. Therefore, it is crucial to determine the accuracy of the collected data.

Accuracy can be determined in several ways. One way is by how close repeated measurements of an attribute are to each other. This method is known as precision. If repeated measurements are consistent with one another, it indicates that the data is precise. However, precision does not necessarily imply accuracy, as the measured values could be consistently wrong.

Another way to determine accuracy is by how close repeated measurements are to the true value of the attribute being measured. This method is known as validity. Validity ensures that the collected data accurately reflects the attribute being measured. This method is often used in experiments to test the effectiveness of a treatment or intervention. The results of an experiment are valid if they accurately reflect the effects of the treatment or intervention being tested.

Accuracy can also be determined by how much deviation there is between the measured values and the true value. This method is known as error. An error is the difference between the measured value and the true value. The smaller the error, the more accurate the data.

In conclusion, accuracy in data collection is determined by how close the measured values are to the true value, how close repeated measurements are to each other, and how much deviation there is between the measured values and the true value. It is essential to determine accuracy to ensure that the collected data is reliable and can be used to make informed decisions.

It will take approximately 6.1 minutes to fill the pool to a depth of 20 cm at the given fill rate.

Find the radius of the pool:

Since the diameter is 115 cm, the radius (r) will be half of that:

Radius (r) = Diameter / 2

r = 115 cm / 2

r = 57.5 cm

Calculate the volume of the pool when filled to a depth of 20 cm:

Since the pool is round and assuming it has a cylindrical shape, we can use the formula for the volume of a cylinder:

Volume = π × r² × h

where π (pi) is approximately 3.14159, r is the radius, and h is the height (or depth, in this case).

Volume = 3.14159 × (57.5 cm)² × 20 cm

Evaluate the volume:

Volume ≈ 3.14159 × 3306.25 cm² × 20 cm

Volume ≈ 3.14159 × 66125 cm³

Volume ≈ 207354.2 cm³

Calculate the time it takes to fill the pool to a depth of 20 cm:

We are given that the hose fills the pool at a rate of 34,000 cm³ per minute. To find out how long it will take to fill the pool, we can use the following formula:

Time = Volume / Fill Rate

Time ≈ 207354.2 cm³ / 34,000 cm³/min

D = 8.3 mm

The radius of the circle is 4.15 mm.

The radius and diameter are both important properties of a circle, and they are related to each other. The diameter is the distance across the circle through its center, while the radius is the distance from the center to any point on the circle. The radius and diameter are related by the formula

D = 2r

Where "D" is the diameter and "r" is the radius.

To calculate the radius of a circle given its diameter, we use the formula

r = D/2

Where "r" is the radius and "D" is the diameter. The formula tells us that the radius is equal to half of the diameter.

In this case, we are given that the diameter is 8.3 mm. To find the radius, we simply substitute this value into the formula and solve for "r"

The equation of the line that goes through the point (0, -4) and has a slope of 2 is y = 2x - 4.

The relationship between the coordinates of each point (x, y) on a line is represented by the equation of a line, which is linear in the variables x and y. All of the points on the line satisfy the equation, in other words.

We can use the point-slope form of the equation of a line to find the equation of the line that goes through the point (0, -4) and has a slope of 2.

The point-slope form of the equation of a line is:

y - y₁ = m(x - x₁)

where (x₁, y₁) is a point on the line and m is the slope of the line.

Plugging in the values, we get:

y - (-4) = 2(x - 0)

Simplifying, we get:

y + 4 = 2x

They have different end behavior as x approaches -∞ but the same end behavior as x approaches ∞.

The correct option is D.

From the given points, we can write an exponential function in the form of f(x) = abˣ, where a and b are constants.

Using the point (-4, 9): 9 = ab⁻⁴

Using the point (0, 1): 1 = ab⁰ = a

Using the point (1, 0): 0 = ab¹

Using the point (5, -2): -2 = ab⁵

Solving these equations, we get a = 1 and b = 1/3. So, the function f(x) = 1(1/3)ˣ = (1/3)ˣ.

For function g(x), we can see that as x approaches -∞, g(x) approaches ∞ , and as x approaches ∞, g(x) approaches 0.

This is because as x gets more negative, 24 times 2⁻ˣ becomes a larger positive number, and as x gets larger, 2ˣ becomes a larger positive number causing the product to approach zero.

Therefore, the two functions have different end behavior as x approaches -∞ but the same end behavior as x approaches ∞, making option D the correct answer.

The two companies charge the same when the amount of sugar is 20 thirds per second and the cost when the two companies charge the same is $8,125.

What is amount?

Amount is a term used to describe the quantity or size of something. It can refer to a specific quantity of a substance, such as an amount of money or an amount of a particular material, or it can refer to a more abstract concept, such as an amount of time or effort.

To find the amount of sugar for which the two companies charge the same, we need to set the two costs equal to each other and solve for the amount of sugar.

Let x be the amount of sugar in third per second. Then, the cost C1 charged by the first company is:

C1 = 4500 + 175.25x

And the cost C2 charged by the second company is:

C2 = 3995 + 200.50x

To find the amount of sugar for which the two companies charge the same, we set C1 equal to C2:

4500 + 175.25x = 3995 + 200.50x

Solving for x, we get:

25.25x = 505

x = 20

Therefore, the two companies charge the same when the amount of sugar is 20 thirds per second.

To find the cost when the two companies charge the same, we can substitute x = 20 into either of the cost equations. Let's use C1:

C1 = 4500 + 175.25x

C1 = 4500 + 175.25(20)

C1 = 8125

Therefore, the cost when the two companies charge the same is $8,125.

a. #(x) = 0.23x^2 - 0.46x + 7.54 (numbers rounded to two decimal places)

b. To find the year at which the number of households living in poverty is at a minimum, we need to find the vertex of the quadratic function. The x-value of the vertex is given by -b/2a. Plugging in the values for a and b from the function in part (a), we get:

x = -(-0.46)/(2*0.23) = 1

So the minimum occurs in the year 1999 + 1 = 2000 (rounded to the nearest year).

c. To find the number of households living in poverty in 2000, we need to evaluate the function at x = 1 (since 2000 is 1 year after 1999). Plugging in x = 1 into the function from part (a), we get:

#(1) = 0.23(1)^2 - 0.46(1) + 7.54 = 7.40

So there were approximately 7400 households living in poverty in Asturias in 2000 (rounded to one decimal place).

Assuming that the cost price in the question is 80K with a 65% profit percentage on cost price, the selling price of the shoe is 132K.

Given, Cost Price (CP) of the shoe = 80K or 80,000

           Profit % = 65%

From the formula, we know,

             Profit % = (Profit / Cost Price) * 100

Inserting given values in the formula, we get,

             ==>  65 = (Profit / 80,000) *100

                or, 65 = Profit / 800

Therefore, Profit = 65 * 800

                           = 52,000

In the case of Profit, Selling Price = Cost Price + Profit

Hence, the Selling Price of the shoe is = 80,000 + 52,000
