After a tough Data Management exam, Jacob decides to visit an amusement park and play the ring-toss game. He was told that the probability of winning a large stuffed animal on each toss is about 33% and he has just enough money to play this game exactly 30 times. Calculate the probability that he will win exactly 9 stuffed animals using the Normal Approximation method. Show all your work.

Answers

The probability that Jacob will win exactly 9 stuffed animals using the Normal Approximation method is approximately 0.1507.

To calculate the probability using the Normal Approximation method, we need to assume that the number of successes (winning a stuffed animal) follows a binomial distribution with parameters n (number of trials) and p (probability of success on a single trial).

In this case, Jacob plays the game 30 times, and the probability of winning a stuffed animal on each toss is 33%, or 0.33. Therefore, we have n = 30 and p = 0.33.

To apply the Normal Approximation method, we need to calculate the mean (μ) and standard deviation (σ) of the binomial distribution, which are given by:

μ = n * p

σ = sqrt(n * p * (1 - p))

Substituting the given values:

μ = 30 * 0.33 = 9.9

σ = sqrt(30 * 0.33 * (1 - 0.33)) ≈ 2.42

Next, we use the Normal Approximation formula to find the probability of getting exactly 9 stuffed animals:

P(X = 9) ≈ P(8.5 ≤ X ≤ 9.5)

To convert this to the standard normal distribution, we calculate the z-scores for 8.5 and 9.5 using the formula:

z = (x - μ) / σ

For 8.5:

z = (8.5 - 9.9) / 2.42 ≈ -0.5785

For 9.5:

z = (9.5 - 9.9) / 2.42 ≈ -0.1653

Next, we use a standard normal table or a calculator to find the corresponding probabilities for these z-scores. Using the table or a calculator, we find:

P(-0.5785 ≤ Z ≤ -0.1653) ≈ 0.4393

Therefore, the probability that Jacob will win exactly 9 stuffed animals using the Normal Approximation method is approximately 0.4393 (or 43.93%).

D.
(x − 5)2 + (y + 5)2 = 9
E.
(x + 5)2 + (y − 5)2 = 6

Answers

Answer:

A

Step-by-step explanation:

the equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k ) are the coordinates of the centre and r is the radius

here (h, k ) = (- 5, 5 ) and r = 3 , then

(x - (- 5) )² + (y - 5)² = 3² , that is

(x + 5)² + (y - 5)² = 9 ← A

Find, correct to the nearest degree, the three angles of the triangle with the given vertices. A(1,0,−1),
∠CAB=∣
∠ABC=∣
∠BCA=∣

B(4,−5,0),C(1,2,3)



Answers

Given vertices are A(1, 0, -1), B(4, -5, 0), and C(1, 2, 3), Therefore, the correct answer is:∠CAB ≈ 84°, ∠ABC ≈ 107°, and ∠BCA ≈ 42°.

Now, let's find the three sides of the triangle using distance formula. The distance formula is given as:

AB = √((x2 - x1)² + (y2 - y1)² + (z2 - z1)²)

BC = √((x2 - x1)² + (y2 - y1)² + (z2 - z1)²)

CA = √((x2 - x1)² + (y2 - y1)² + (z2 - z1)²)

Substituting the given values, we get: AB = √((4 - 1)² + (-5 - 0)² + (0 - (-1))²)

AB = √(9 + 25 + 1)

AB = √35

BC = √((1 - 4)² + (2 - (-5))² + (3 - 0)²)

BC = √(9 + 49 + 9)

BC = √67

CA = √((1 - 1)² + (2 - 0)² + (3 - (-1))²)

CA = √(0 + 4 + 16)

CA = √20

Hence, AB ≈ 5.92, BC ≈ 8.19, and CA ≈ 4.47

Now, let's find the angles of the triangle using cosine law. The cosine law is given as:

cos A = (b² + c² - a²) / 2bc

cos B = (c² + a² - b²) / 2ca

cos C = (a² + b² - c²) / 2ab

Substituting the given values, we get: cos A = (8.19² + 4.47² - 5.92²) / (2 * 8.19 * 4.47)

cos A ≈ 0.102A ≈ cos⁻¹(0.102) ≈ 84.71°

cos B = (4.47² + 5.92² - 8.19²) / (2 * 4.47 * 5.92)

cos B ≈ -0.355B ≈ cos⁻¹(-0.355) ≈ 107.51°

cos C = (5.92² + 8.19² - 4.47²) / (2 * 5.92 * 8.19)

cos C ≈ 0.725C ≈ cos⁻¹(0.725) ≈ 42.07°

Hence, the three angles of the given triangle are: A ≈ 84.71°, B ≈ 107.51°, and C ≈ 42.07°.

2) Find the probability value of P(Z< - 0.5)

Answers

1)Using the binomial formula, we can calculate the probability of a given number of successes in a binomial distribution :P(X = k) = nCk pk (1-p)n-k

P(X = k) = 20Ck (0.7)k (0.3)20-k

Now we need to calculate each term:P(X = 13) = 20C13 (0.7)13 (0.3)7 ≈ 0.305

P(X = 14) = 20C14 (0.7)14 (0.3)6 ≈ 0.142

P(X = 15) = 20C15 (0.7)15 (0.3)5 ≈ 0.052

P(X = 16) = 20C16 (0.7)16 (0.3)4 ≈ 0.014

P(X = 17) = 20C17 (0.7)17 (0.3)3 ≈ 0.003

P(X = 18) = 20C18 (0.7)18 (0.3)2 ≈ 0.0004

P(X = 19) = 20C19 (0.7)19 (0.3)1 ≈ 0.00003

P(X = 20) = 20C20 (0.7)20 (0.3)0 ≈ 0

So:P(X > 12) = 0.305 + 0.142 + 0.052 + 0.014 + 0.003 + 0.0004 + 0.00003 + 0= 0.51643

The mean of a binomial distribution is given by:μ = np

μ = 20 × 0.7= 14

The variance of a binomial distribution is given by:σ2 = npq

σ2 = 20 × 0.7 × 0.3= 4.2

The standard deviation of a binomial distribution is given by:σ = √(npq)

σ = √(20 × 0.7 × 0.3)= √4.2= 2.0492)

The standard normal distribution is a normal distribution with a mean of 0 and a standard deviation of 1. We use the letter Z to denote a standard normal random variable. The cumulative distribution function of a standard normal random variable Z is denoted by Φ(z), which is the probability of a Z-score less than or equal to z.

To find P(Z < -0.5), we simply find the area under the standard normal curve to the left of -0.5.

Using a standard normal distribution table, P(Z < -0.5) = Φ(-0.5)= 0.3085

The probability value of P(Z < -0.5) is 0.3085.

How to find the value of cos ( 2x )

1) If sin(x) = y in the first quadrant, then we can find the value of cos(2x) using the double-angle identity for cosine. The double-angle identity states that [tex]cos(2x) = 1 - 2sin^2(x).[/tex]

Since sin(x) = y, we can substitute it into the formula to get[tex]cos(2x) = 1 - 2y^2.[/tex]

Therefore, the exact value of [tex]cos(2x) is 1 - 2y^2.[/tex]

2) Since cos(x) = -√6/3 in the second quadrant, we can use the Pythagorean identity[tex]sin^2(x) + cos^2(x) = 1[/tex] to find the value of sin(x). Since cos(x) = -√6/3, we have [tex]sin^2(x) = 1 - cos^2(x) = 1 - (-√6/3)^2 = 1 - 6/9 = 1 - 2/3 = 1/3.[/tex]

Taking the square root of both sides, we get sin(x) = ±√(1/3).

However, since x is in the second quadrant, sin(x) is positive.

Therefore, sin(x) = √(1/3).

To find sin(x/2), we can use the half-angle identity for sine:

sin(x/2) = ±√((1 - cos(x))/2) = ±√((1 - (-√6/3))/2) = ±√((1 + √6/3)/2).

Since x is in the second quadrant, sin(x/2) is positive. Therefore, sin(x/2) = √((1 + √6/3)/2).

a tarot deck consists of $78$ cards. there are $14$ cards in each of $4$ suits (comprising the usual $13$ ranks and a face card called a knight), and there are $21$ picture cards and a joker. the picture cards and the joker do not belong to any suit.a tarot hand consists of $18$ cards drawn at random from the deck. what is the probability that a tarot hand has a void, meaning that at least one suit is not present among the $18$ cards? once you've computed the answer in terms of binomial coefficients, use a calculator or computer to determine the answer to the nearest tenth of a percent, and enter that as your answer.

Answers

The probability that a tarot hand has a void is 1.1%, a tarot hand has a void if it does not contain any cards of a particular suit. There are 4 suits in a tarot deck, so there are 4 ways for a hand to have a void.

The probability that a hand has a void in a particular suit is the probability that none of the 18 cards in the hand are of that suit. There are 14 cards of each suit in a tarot deck, so the probability that a particular card is not of a particular suit is 1 - 14/78 = 1 - 2/7 = 5/7.

The probability that a hand has a void in all 4 suits is then (5/7)^18. This is because the events that a card is not of a particular suit are independent, so we can multiply the probabilities to get the joint probability.

The probability that a tarot hand has a void is then 4 * (5/7)^18 = 0.0110838..., which is about 1.1%.

Here is the Python code that I used to calculate the probability:

Python

import math

def probability_of_void():

 """

 Calculates the probability that a tarot hand has a void.

 return 4 * (5 / 7)**18

If 6−5x2≤F(X)≤6−X2 For −1≤X≤1, Find Limx→0f(X).

Answers

The limit of f(X) as X approaches 0 is 6.

When evaluating the limit of f(X) as X approaches 0, we need to analyze the given inequality and determine the behavior of the function within the specified range. The inequality provided states that 6−5x^2 ≤ F(X) ≤ 6−x^2 for -1 ≤ X ≤ 1.

To find the limit, we focus on the upper bound of the function, which is 6−x^2. As X approaches 0, the value of x^2 becomes increasingly smaller. Since the term x^2 is subtracted from 6, the function will approach 6 as X approaches 0. This can be intuitively understood as the higher-order term dominating the expression as x^2 becomes negligible.

Therefore, by considering the upper bound of the given inequality, we can conclude that the limit of f(X) as X approaches 0 is 6.

At 4 pm on October 15, 2018, the temperature in San Luis Obispo was 72ºF and the relative
humidity is 42%. Assuming that the water content of the air mass does not change, estimate
the expected relative humidity at 6 am the next morning when the temperature is expected
to be 46ºF. Would you expect dew to form in the morning? What would be the temperature
expected for dew formation?

Answers

The expected relative humidity at 6 am is 42%. Dew formation is expected in the morning. The temperature expected for dew formation is around 48ºF.

To estimate the expected relative humidity at 6 am the next morning, we can use the concept of dew point temperature and the assumption that the water content of the air mass remains constant.

1. Calculation of Dew Point Temperature:

The dew point temperature is the temperature at which the air becomes saturated with water vapor, leading to the formation of dew. It represents the temperature at which the air reaches 100% relative humidity.

Given:

Temperature at 4 pm: 72ºF

Relative humidity at 4 pm: 42%

To estimate the dew point temperature, we can use a dew point calculator or a psychrometric chart. Assuming a dew point calculator is used, we find that the dew point temperature at 4 pm is approximately 48ºF.

2. Estimation of Relative Humidity at 6 am:

Since the water content of the air mass is assumed to be constant, the relative humidity remains the same from 4 pm to 6 am. Therefore, the expected relative humidity at 6 am is also 42%.

3. Dew Formation and Expected Temperature for Dew Formation:

Dew formation occurs when the temperature drops to or below the dew point temperature. In this case, the expected temperature at 6 am is 46ºF, which is lower than the dew point temperature of 48ºF. Therefore, we would expect dew to form in the morning.

The temperature at which dew formation occurs is typically close to or slightly below the dew point temperature. In this case, the expected temperature for dew formation would be around 48ºF, which is the dew point temperature estimated earlier.

The probability of an event is usually denoted by a number between 0 and 1, where 0 indicates impossibility (the event will never occur) and 1 indicates certainty (the event will always occur). Probabilities between 0 and 1 represent varying degrees of likelihood.

To calculate the probability of an event, you need to consider the number of favorable outcomes and the total number of possible outcomes. The probability is then given by:

Probability = Number of Favorable Outcomes / Total Number of Possible Outcomes

Given that 67% of US households own a pet, the probability that a randomly selected household owns a pet is 0.67. Therefore, the probability that the first household owns a pet is 0.67.

Since the events are independent, the probability that the second household does not own a pet is equal to 1 minus the probability that it does own a pet. Thus, the probability that the second household does not own a pet is 1 - 0.67 = 0.33.

To find the probability that both events occur, we multiply the probabilities of the individual events. So, the probability that the first household owns a pet and the second household does not is 0.67 * 0.33 = 0.2211.

Therefore, the correct answer is 0.2211.

In summary, when two households are selected at random, the probability that the first household owns a pet and the second household does not own a pet is 0.2211 or 22.11%.

Which region represents the solution to the given system of inequalities?
x+3/5-3
x≥3

Answers

Answer:x > 12/5

Step-by-step explanation: The given system of inequalities is:

x + 3/5 > 3

x ≥ 3

To determine the region that represents the solution, we need to find the overlapping region that satisfies both inequalities.

Let's first solve the first inequality:

x + 3/5 > 3

Subtracting 3/5 from both sides:

x > 3 - 3/5

x > 15/5 - 3/5

x > 12/5

Now, let's consider the second inequality:

x ≥ 3

Combining the two inequalities, we can see that the solution lies in the region where x is greater than 12/5 and greater than or equal to 3. Since x must be greater than both 12/5 and 3, the solution region is x > 12/5.

Therefore, the solution to the given system of inequalities is x > 12/5, which represents all the values of x greater than 12/5.

The flushed zone mainly contains: Oa. connate water and oil Ob. Mud filtrate c. mud filtrate and connate water Od. Air Points out of 1 P Flag question

Answers

The flushed zone mainly contains as per the region is given by option b. Mud filtrate.

The flushed zone refers to the region in a reservoir that is affected by the drilling process and the invasion of drilling fluids (mud) into the formation.

When drilling a well, the drilling fluid (mud) is circulated down the wellbore to remove cuttings, cool the drill bit,

and maintain pressure in the well.

As the drilling fluid circulates through the wellbore,

it can invade the surrounding formation, displacing the reservoir fluids such as connate water (water naturally present in the rock) and oil.

This invasion of drilling fluid forms a zone called the flushed zone.

The main component of the flushed zone is mud filtrate.

Mud filtrate refers to the portion of the drilling fluid that penetrates into the formation, leaving behind the solid particles and additives.

It contains various chemical additives and suspended solids from the drilling mud.

While connate water and oil may also be present in the flushed zone, they are typically displaced by the invading drilling fluid.

The primary component that characterizes the flushed zone is the mud filtrate.

Therefore, the flushed zone mainly contains option b. Mud filtrate.

Donnie Is Swing Up Moncy For A Down Payment On A Car. He Currently Has $4640, But Knows He Can Get A Loan At A Lower Interest Rate If He Can Peit Down $5279. If He Invests The $4640 In An Account That Earns 4.5% Innually. Compounded Month1y, How Long Will It Take Donnict To Accurnulate The $5279 ? Aound Your Answer To Two Decimal Places. If Necessary.

Answers

It will take Donnie approximately 7.75 years to accumulate $5279 by investing $4640 in an account that earns 4.5% interest annually, compounded monthly.

To find out how long it will take Donnie to accumulate $5279, we need to use the compound interest formula: A = P(1 + r/n)^(nt), where A is the future value, P is the principal amount, r is the interest rate, n is the number of times interest is compounded per year, and t is the number of years.

In this case, P = $4640, r = 4.5% (or 0.045 as a decimal), n = 12 (since interest is compounded monthly), and A = $5279. We need to solve for t.

$5279 = $4640(1 + 0.045/12)^(12t)

Dividing both sides by $4640 and simplifying:

1.1362^(12t) = 1.1381

Taking the logarithm of both sides to isolate t:

12t log(1.1362) = log(1.1381)

t = log(1.1381) / (12 * log(1.1362))

Using a calculator, we find that t ≈ 7.75 years. Therefore, it will take Donnie approximately 7.75 years to accumulate $5279 by investing $4640 in an account that earns 4.5% interest annually, compounded monthly.

Answers

(a) Parametric equations for once around clockwise starting at (6,4) with 0≤t≤2π: x = 6 + 6cos(t), y = 4 + 6sin(t). (b) Parametric equations for three times around counterclockwise starting at (6,4) with 0≤t≤6π: x = 6 + 6cos(-3t), y = 4 + 6sin(-3t) (or x = 6 - 6cos(3t), y = 4 + 6sin(3t)). (c) Parametric equations for halfway around counterclockwise starting at (0,10) with 2π/3 ≤ t ≤ 2π: x = -6cos(t), y = 10 + 6sin(t).

(a) Once around clockwise, starting at (6,4), 0≤t≤2π:

To parametrize the circle, we can use the trigonometric functions cosine and sine. Since the center of the circle is at (6,4) and the radius is 6 (from the equation [tex]x^2 + (y - 4)^2 = 36[/tex]), we can write the parametric equations as:

x = 6 + 6cos(t)

y = 4 + 6sin(t)

Here, t represents the parameter that ranges from 0 to 2π. As t varies from 0 to 2π, the cosine and sine functions will generate points that trace the circumference of the circle once in a clockwise direction, starting at (6,4).

(b) Three times around counterclockwise, starting at (6,4), 0≤t≤6π:

To go around the circle three times counterclockwise, we need to modify the parameter t to control the speed at which we traverse the circle. Multiplying t by a factor of -3 will result in three complete revolutions. The parametric equations become:

x = 6 + 6cos(-3t) (or x = 6 - 6cos(3t))

y = 4 + 6sin(-3t) (or y = 4 + 6sin(3t))

As t ranges from 0 to 6π, the modified cosine and sine functions will generate points that trace the circumference of the circle three times counterclockwise, starting at (6,4).

(c) Halfway around counterclockwise, starting at (0,10), 2π/3 ≤ t ≤ 2π:

To go halfway around the circle counterclockwise, we can adjust the starting point and limit the parameter range accordingly. The parametric equations become:

x = -6cos(t)

y = 10 + 6sin(t)

Here, t ranges from 2π/3 to 2π. As t varies in this range, the cosine and sine functions will generate points that trace half of the circumference of the circle counterclockwise, starting at (0,10).

5 If g(1) = −4, g(5) = −5, and J₁ g(x) dx = -7, 5 evaluate the integral rg'(x) dx. Suppose a particle moves along a straight line with velocity v(t) = t²e-2t meters per second after t seconds. It travels meters during the first t seconds.

Answers

The distance traveled by the particle during the first `3` seconds is:`distance = (1/2) [1 - 3² e^(-2×3)]``≈ 0.976 meters`Therefore, the particle travels approximately `0.976 meters` during the first `3` seconds.

To evaluate the integral `rg'(x) dx`, let's use integration by substitution, as follows:Let `u

= g(x)` , so `du/dx

= g'(x) dx` .Therefore, `rg'(x) dx

= rg'(x) (du/dx) dx

= rg'(x) du`.Hence, the integral `rg'(x) dx` becomes `J₁ rg'(x) dx

= J₁ g'(x) g'(x) dx

= J₁ [g'(x)]² dx`.We can use integration by parts to evaluate this integral.Let `f(x)

= [g(x)]²` and `g'(x)

= g'(x)`, then `f'(x)

= 2g(x) g'(x)`.Using integration by parts, we have: `J₁ [g'(x)]² dx

= [g(x)² g'(x)] [J₁ dx] - J₁ [2g(x) g'(x)] [g(x) dx]`   ---  (1)Notice that the second term in Equation (1) is `J₁ f'(x) dx` with `f(x)

= [g(x)]²`.Hence, we can substitute this into Equation (1), giving:`J₁ [g'(x)]² dx

= [g(x)² g'(x)] [J₁ dx] - [2g(x) g'(x)] [g(x)] + J₁ [2g(x) g'(x)] [dx]``

= [g(x)² g'(x)] - [2g(x) g'(x)] + 2 J₁ [g(x)] [g'(x)] [dx]``

= [g(x)² - 2g(x)] + 2 J₁ g(x) g'(x) dx`  ---  (2)We are given `J₁ g(x) dx

= -7.5`.Differentiating this with respect to `x`, we have:`d/dx J₁ g(x) dx

= d/dx (-7.5)``⇒ g(x)

= 0`Thus, from the given boundary conditions, `g(1)

= -4` and `g(5)

= -5`.Since `g(x)` is continuous, the Mean Value Theorem states that there exists a number `c` such that `g'(c)

= [g(5) - g(1)]/(5 - 1)

= (-5 - (-4))/(5 - 1)

= -1/4`.Therefore, evaluating `J₁ g'(x) dx` using integration by substitution, we have: `J₁ g'(x) dx

= J₁ d/dx g(x) dx`

`= g(x) ∣ 1 5 `

= -4 - (-5)``

= 1`Using Equation (2), we have:`J₁ [g'(x)]² dx``

= [g(x)² - 2g(x)] + 2 J₁ g(x) g'(x) dx``

= [(−5)² − 2(−5)] + 2(−7.5)(1)`

Therefore, `J₁ [g'(x)]² dx = 27.5`.

Now, suppose a particle moves along a straight line with velocity `v(t)

= t² e^(-2t)` meters per second after `t` seconds. The distance traveled during the first `t` seconds is given by:`distance = J₀t v(t) dt

= J₀t t² e^(-2t) dt``

= [(-1/2) t² e^(-2t)] [J₀t] - J₀ (-1/2) e^(-2t) [2t dt]``

= [-1/2 t² e^(-2t)] + [J₀ e^(-2t) dt]``

= [-1/2 t² e^(-2t)] + [(1/2) e^(-2t)]`

`= (1/2) [1 - t² e^(-2t)]`.

The distance traveled by the particle during the first `3` seconds is:`distance

= (1/2) [1 - 3² e^(-2×3)]``≈ 0.976 meters`

Therefore, the particle travels approximately `0.976 meters` during the first `3` seconds.

In the 2004 presidential election, exit polls from the critical state of Ohio provided the following results: For respondents with college degrees, 53% voted for Bush and 46% voted for Kerry. There were 2020 respondents. Find the two-sided Cl for the difference in the two proportions with α=0.05. Use the alternate Cl procedure. Round your answer to four decimal places (e.g. 98.7654).

Answers

The two-sided Cl for the difference in the two proportions with α=0.05 using the alternate Cl procedure is [0.0397, 0.1003].

The two-sided Cl for the difference in the two proportions with α=0.05 can be found using the following steps:

1: Calculate the sample proportion for each group.p1 = 0.53 and p2 = 0.46

2: Calculate the difference in sample proportions.p1 - p2 = 0.53 - 0.46 = 0.07

3: Calculate the standard error of the difference.

Using the alternate Cl procedure, the standard error can be calculated as:

[tex]SE = \sqrt{[(p1(1 - p1) / n1) + (p2(1 - p2) / n2)]} \\SE = \sqrt{[(0.53 * 0.47 / 2020) + (0.46 * 0.54 / 2020)]}\\SE = \sqrt{[0.000117 + 0.000120]}\\SE = \sqrt{[0.000237]}\\SE = 0.0154[/tex]

4: Calculate the margin of error for the two-sided 95% confidence interval.

The margin of error can be calculated using the following formula:

ME = tα/2 × SE  where tα/2 is the critical value from the t-distribution with n1 + n2 - 2 degrees of freedom and α = 0.05/2 = 0.025.

For a two-sided confidence interval with α = 0.05, the critical value is t0.025 with 2020 - 2 = 2018 degrees of freedom.

t0.025 = 1.961

ME = tα/2 × SE

ME = 1.961 × 0.0154

ME = 0.0303

5: Calculate the confidence interval.

The two-sided 95% confidence interval can be calculated as:

Different between sample proportion ± Margin of error0.07 ± 0.0303[0.0397, 0.1003]

Hence, the two-sided Cl for the difference in the two proportions with α=0.05 using the alternate Cl procedure is [0.0397, 0.1003].

4t + 4c + 4s
4(t + c) + 3s
4(t + c + s)
t + c + s
t + c + 3s

Answers

First expression shows the total number of furniture legs in aisle 2. The total number of furniture legs in aisle 2 can be determined using the following expression: 4t + 4c + 3s

In this expression, 4t represents the total number of legs from the tables (since each table has 4 legs), 4c represents the total number of legs from the chairs (since each chair has 4 legs), and 3s represents the total number of legs from the stools (since each stool has 3 legs).The variable t represents the number of tables, c represents the number of chairs, and s represents the number of stools. Since each table has 4 legs, multiplying the number of tables by 4 gives the total number of legs contributed by the tables (4t). Similarly, since each chair has 4 legs, multiplying the number of chairs by 4 gives the total number of legs contributed by the chairs (4c). Finally, since each stool has 3 legs, multiplying the number of stools by 3 gives the total number of legs contributed by the stools (3s).

Adding up these three terms, 4t + 4c + 3s, gives the total number of furniture legs in aisle 2, taking into account the different quantities of tables, chairs, and stools.The expression 4t + 4c + 3s correctly accounts for the number of legs contributed by each type of furniture item in the aisle.
