Answer:

Luisa has $18

Step-by-step explanation:

Let us solve the question

∵ Carlos has $24

∵ Carlos has 1 \(\frac{1}{3}\)  as much money as Luisa has

→ Let Luisa has x dollars

∵ Luisa has x dollars

∴ Carlos money = 1 \(\frac{1}{3}\) × x

∴ Carlos money = 1 \(\frac{1}{3}\) x

→ Change the mixed number to an improper fraction

∵ 1 \(\frac{1}{3}\) = \(\frac{1(3)+1}{3}\) = \(\frac{4}{3}\)

∴ Carlos money = \(\frac{4}{3}\) x

→ Substitute the Carlos money by 24

∵ 24 = \(\frac{4}{3}\) x

→ Multiply both sides by 3

∵ 24 × 3 = 4x

∴ 72 = 4x

→ Divide both sides by 4

∴ 18 = x

∴ Luisa has $18

Step-by-step explanation:

To find the value of j - i, we need to determine the relationship between the surface areas (An) and volumes (Vn) of the unit ball in Rn for different positive integers n.

For the unit ball in Rn, the formula for surface area (An) and volume (Vn) are given by:

An = (2 * π^(n/2)) / Γ(n/2)

Vn = (π^(n/2)) / Γ((n/2) + 1)

where Γ denotes the gamma function.

To find the value of j - i, we need to identify the positive integers i and j such that Ai > Ak for all k not equal to i, and Vj > Vk for all k not equal to j.

First, let's analyze the relationship between An and Vn. By comparing the formulas, we can see that:

An / Vn = [(2 * π^(n/2)) / Γ(n/2)] / [(π^(n/2)) / Γ((n/2) + 1)]

      = 2 / [n * (n-1)]

From this equation, we can deduce that An / Vn > 1 if and only if 2 > n * (n-1).

To find the positive integer i, we need to identify the highest positive integer n for which 2 > n * (n-1) holds true. We can observe that this condition is satisfied for n = 2. Therefore, i = 2.

Now, let's find the positive integer j. We need to identify the lowest positive integer n for which 2 > n * (n-1) does not hold true. We can observe that this condition is no longer satisfied for n = 3. Therefore, j = 3.

Finally, we can calculate j - i as follows:

j - i = 3 - 2 = 1

Therefore, j - i equals 1.

The correct answer is d. Sometimes it is difficult to assign random numbers.

Systematic random sampling is often used in place of simple random sampling when it is difficult or impractical to assign random numbers. In systematic random sampling, a starting point is randomly chosen from the population, and then every nth element is selected to be part of the sample.

This method provides a more representative sample than other non-random methods and can be more efficient than simple random sampling in certain situations. However, it is still prone to bias if the pattern of the sampling interval coincides with any underlying patterns in the population.

Step-by-step explanation:

Surface Area = BH +Lp

B is the base area

H is the height of the Prism

L is the slant height

p is t perimeter of its base

B =1/2 ×3×4

B= 6cm²

H = 7cm

L = 5cm

P = 3cm+4cm+5cm

P = 12cm

Substitute

TSA = 6(7)+5(12)

TSA = 42+60

TSA = 102cm²

Hence the total surface area of the shape is 102cm²

Answer:

To find the area of a triangle, we can use the formula:

Area = (base * height) / 2

To find the area of triangle ABC, we first need to find the base and the height.

Since angle B is 75 degrees, we can use the fact that the sum of the angles in a triangle is 180 degrees to find the measure of angle A: 180 - 75 - 90 = 15 degrees.

Then, we can use the fact that the measure of an angle in a triangle is proportional to the length of the side opposite that angle to find the length of side AC:

AC/AB = m∠A/m∠B

AC = (m∠A/m∠B) * AB

Substituting, we get:

AC = (15/75) * 12 = 3

Now that we know the base and the height of the triangle, we can use the formula to find the area:

Area = (3 * 12) / 2 = 18

Therefore, the area of triangle ABC is 18 square cm.

Step-by-step explanation:

The average rate of change of the height function is slope of the height function

The model's height increases by approximately 0.011 inch for every 1-cubic-inch increase in its volume.

The height function is given as:

\(H(V) = 2.69\sqrt[3]{V}\)

When V = 512, the function becomes

\(H(512) = 2.69\sqrt[3]{512}\)

\(H(512) = 21.52\)

Similarly;

When V = 1000, the function becomes

\(H(1000) = 2.69\sqrt[3]{1000}\)

\(H(1000) = 26.9\)

The average rate of change is then calculated as:

\(H' = \frac{H(1000) - H(512)}{1000 - 512}\)

This gives

\(H' = \frac{26.9 - 21.52}{1000 - 512}\)

\(H' = \frac{5.38}{488}\)

Evaluate the quotient

\(H' = 0.01102459016\)

Approximate

\(H' = 0.011\)

It represents the level of output at which planned spending (I + C + G) equals total income.

The IS curve is the intersection of the investment and saving curve. The investment curve is a downward sloping curve, while the saving curve is upward sloping. It can be obtained by equating total income with total output and deriving the relationship between interest rates and GDP.

It represents the combinations of interest rates and output where the market for goods and services is in equilibrium. The equation for the IS curve can be given as:Y = C(Y-T) + I(r) + G

Where, C(Y-T) is consumption I(r) is investment Y is output G is government spending T is taxes r is the interest rateGiven,C0 = 300T = 400G = 400I0 = 300c1 = 0.4b = 1

⇒ Y = C0 + c1 (Y-T) + I0 + bY - br + G

⇒ Y - c1Y + br = C0 - c1T + I0 + G

⇒ (1-c1) Y = C0 - c1T + I0 + G - br

(a)the body temperature of the 1601 lb man will increase by approximately 3.0 °C.(b)the body temperature of the 160 lb man will increase by approximately 2.4 °C.

The specific heat of a human is given as 3.47 J/°C. Using this information, we can calculate the increase in body temperature when a certain number of calories are converted into heat energy. In the first scenario, a 1601 lb man consumes a candy bar containing 287 Cal. In the second scenario, a 160 lb man consumes a roll of candy containing 41.9 Cal. We will calculate the increase in body temperature for each case.

(a) To calculate the increase in body temperature for a 1601 lb man who consumes a candy bar containing 287 Cal, we need to convert calories to joules. Since 1 Calorie (Cal) is equal to 4184 joules, we have:
Energy = 287 Cal × 4184 J/Cal = 1.2 × \(10^6\) J
Now, using the specific heat formula Q = mcΔT, where Q is the energy, m is the mass, c is the specific heat, and ΔT is the change in temperature, we can rearrange the formula to solve for ΔT:
ΔT = Q / (mc)
Assuming the mass of the man is converted to kilograms, we have:
ΔT = (1.2 × \(10^6\) J) / (1601 lb × 0.4536 kg/lb × 3.47 J/°C) ≈ 3.0 °C
Therefore, the body temperature of the 1601 lb man will increase by approximately 3.0 °C.
(b) For a 160 lb man who consumes a roll of candy containing 41.9 Cal, we repeat the same calculation:
Energy = 41.9 Cal × 4184 J/Cal = 1.75 × \(10^5\) J
ΔT = (1.75 × \(10^5\) J) / (160 lb × 0.4536 kg/lb × 3.47 J/°C) ≈ 2.4 °C
Thus, the body temperature of the 160 lb man will increase by approximately 2.4 °C.

The answer is that the expected waiting time until the next service completion is 7.44 minutes.



To calculate the expected waiting time, we need to first find the expected remaining service time for each server. Since the service times are exponentially distributed, the expected remaining service time for each server is equal to the reciprocal of its service rate. The service rate is the inverse of the expected service time.

Thus, the expected remaining service time for the first server is 1/λ1 = 1/0.2 = 5 minutes, where λ1 is the arrival rate for the first server. Similarly, the expected remaining service time for the second and third servers are 1/λ2 = 1/0.0333 = 30 minutes and 1/λ3 = 1/0.1 = 10 minutes, respectively.

Since each server has been busy for 5 minutes with a current customer, the expected remaining service time for each server is reduced by 5 minutes. Thus, the expected remaining service times are 0 minutes, 25 minutes, and 5 minutes, respectively.

The expected waiting time until the next service completion is equal to the sum of the expected remaining service times weighted by the probability that a customer arrives at each server while it is busy. The probability of a customer arriving at each server while it is busy can be calculated using the Erlang C formula.

Using the Erlang C formula, we can calculate that the probability of a customer arriving at the first server while it is busy is 0.016, the probability of a customer arriving at the second server while it is busy is 0.524, and the probability of a customer arriving at the third server while it is busy is 0.091.

Thus, the expected waiting time until the next service completion is (0 minutes)*(0.016) + (25 minutes)*(0.524) + (5 minutes)*(0.091) = 7.44 minutes.

So, $131,701.32 is approximately 16.67% of $790,207.91.

In this case, the part is $131,701.32 and the whole is $790,207.91.

Percentage = ($131,701.32 / $790,207.91) * 100

Calculating the value:

Percentage ≈ 0.1667 * 100

Percentage ≈ 16.67%

Therefore, $131,701.32 is approximately 16.67% of $790,207.91.

Alternatively, we can calculate the percentage by dividing the part by the whole and multiplying by 100:

Percentage = ($131,701.32 / $790,207.91) * 100 ≈ 0.1667 * 100 ≈ 16.67%
