(a) The function is known as Logistic growth function.

(c) In this function, L represents the carrying capacity of the environment for this population.

What is Logistic growth function?

When a population grows logistically, its rate of per capita growth declines as it gets closer to the carrying capacity, a limit set by the environment's finite resources ( K). A J-shaped curve results from exponential growth, while an S-shaped curve results from logistic growth.

Let, the given function is, \(f(t) = \frac{L}{1+Ce^-^b^t}\)

A logistic growth function simulates the real-world values whose growth rates alternate between increasing and declining. These functions' typical form is,

\(f(t) = \frac{L}{1+Ce^-^b^t}\)

So, the function is known as logistic growth function.

And L represents the carrying capacity of the environment for this population.

Therefore, the height of the tree is approximately 3.67 meters making triangle.

Let h be the height of the tree. Then, using the properties of similar triangles, we can set up the following proportion:

h / 1.25 = (h + x) / 15.45

where x is the length of Gabriella's shadow. To find x, we can use a similar proportion:

h / 10.2 = 1.25 / x

Solving the second proportion for x, we get:

x = 10.2 * 1.25 / h

Substituting this expression for x into the first proportion, we get:

h / 1.25 = (h + 10.2 * 1.25 / h) / 15.45

Multiplying both sides by 15.45 * h * 1.25, we get:

15.45 * h - 15.45 * 1.25 = h * 10.2

Expanding and rearranging, we get a quadratic equation in h:

15.45h - 19.3125 = 10.2h

5.25h = 19.3125

h = 3.67 meters (rounded to two decimal places)

The probability of 3 dying of SIDS in this situation is approximately 0.000227. The number of SIDS cases in this hospital is significantly higher than the expected rate.

a. The probability of 3 infants dying of SIDS in this situation can be calculated using the binomial probability formula:
P(X=k) = C(n,k) * p^k * (1-p)^(n-k)
Where:
P(X=k) is the probability of k successes (SIDS cases) in n trials (infants),
C(n,k) is the number of combinations of n items taken k at a time,
p is the probability of SIDS (0.0001),
n = 100 infants,
k = 3 SIDS cases.
P(3 SIDS cases in 100 infants) = C(100,3) * (0.0001)^3 * (1-0.0001)^(100-3)
After calculating, the probability is approximately 0.000227.

b. In this situation, it is alarming that many infants died of SIDS, as the probability of 3 deaths in 100 infants is very low (0.000227), much lower than the prevalence of 0.01%. This indicates that the number of SIDS cases in this hospital is significantly higher than the expected rate.

The Taylor series (centered at c = \(\pi\)/4) for the function\(f(x) = 3sin(x)\) is:

\(f(x) = 3(sin(\pi /4) + cos(\pi /4)(x - \pi /4) - (sin(\pi /4)/2)(x - \pi /4)^2 + (cos(\pi /4)/6)(x - \pi /4)^3)\)

The Taylor series expansion of a function allows us to approximate the function using a polynomial expression. In this case, we are given the function \(f(x) = 3sin(x)\) and the center \(c = \pi 4\). The Taylor series is derived by taking derivatives of the function and evaluating them at the center. The coefficients of the series are determined by the values of these derivatives.

In the main answer, we have the Taylor series expansion for f(x) centered at \(c = \pi /4\). It starts with the first term \(3sin(\pi /4)\), which is the value of the function at the center. The subsequent terms involve powers of \((x - \pi /4)\)multiplied by the corresponding coefficients, which are determined by the derivatives of sin(x) evaluated at \(\pi\)/4.

Explanation:

Here, we want to solve the given inequality

We proceed as follows:

To cut the margin of error for a given confidence level in half, you would need to quadruple the sample size.

The margin of error is influenced by three factors: the desired confidence level, the standard deviation of the population, and the sample size. Assuming the confidence level and standard deviation remain constant, the margin of error decreases as the sample size increases.

The relationship between the sample size and the margin of error is approximately inversely proportional. Therefore, to cut the margin of error in half, you would need to double the sample size. However, this only reduces the margin of error by 50%, not 100%.

To achieve a reduction of 100% in the margin of error, you would need to quadruple the sample size. This is because if you double the sample size, you reduce the margin of error by 50%. Then, doubling it again reduces the remaining margin of error by another 50%, resulting in a total reduction of 75%. Doubling it for the third time reduces the remaining margin of error by another 50%, resulting in a total reduction of 87.5%. Finally, doubling it for the fourth time reduces the remaining margin of error by another 50%, resulting in a total reduction of 93.75%. Therefore, to achieve a reduction of 100% and cut the margin of error in half, you need to quadruple the sample size.

To cut the margin of error for a given confidence level in half, you would need to quadruple the sample size. Increasing the sample size helps to reduce the margin of error as it provides more data points, leading to more accurate estimates. However, it is important to note that increasing the sample size also incurs additional costs and efforts in data collection and analysis. Therefore, it is crucial to carefully consider the trade-off between the desired level of accuracy and the practical constraints of the study.

For the quadratic function f(x) = 3x² - 8x + 2, the x-intercepts are x1 = (4 + √10) / 3 and x2 = (4 - √10) / 3.

What is a quadratic function?

A polynomial function with one or more variables, where the largest exponent of the variable is two, is referred to as a quadratic function. It is also known as the polynomial of degree 2 since the greatest degree term in a quadratic function is of second degree.

The given quadratic function is - f(x) = 3x² - 8x + 2.

The quadratic function is in the standard form ax² + bx + c = 0.

Here, a = 3, b = -8 and c = 2.

The x-intercepts can be found using the formula -

x1 = (-b + √Δ) / (2a)

x2 = (- b - √Δ) / (2a)

Here, Δ = b² - 4ac.

Substitute the values in the above equation -

Δ = b² - 4ac

Δ = (-8)² - 4(3)(2)

Δ = 64 - 24

Δ = 40

Now, substitute the value of Δ in the x-intercepts formula -

x1 = [-(-8) + √40) / [2(3)]                x2 = [-(-8) - √40) / [2(3)]

Open the brackets and use arithmetic operation of multiplication -

x1 = (8 + √40) / 6                          x2 = (8 - √40) / 6

Take out the common value -

x1 = (8 + 4√10) / 6                         x2 = (8 - 4√10) / 6

Use arithmetic operation of division -

x1 = (4 + √10) / 3                           x2 = (4 - √10) / 3    

Therefore, the x-intercepts are x1 = (4 + √10) / 3 and x2 = (4 - √10) / 3.

The probability that the first student Mr. Beal selects has a pass or has completed the homework assignment is approximately 46.51%.

To find the probability that the first student Mr. Beal selects has a pass or has completed the homework assignment, we need to calculate the proportion of students who have a pass or have completed the assignment out of the total number of students.

Given the following information:

Total number of students: 43

Number of students who have completed the homework assignment: 18

Number of students who have a pass: 9

Number of students who have a pass and have completed the assignment: 7

To calculate the probability, we can add the number of students who have a pass (9) to the number of students who have completed the assignment (18), and subtract the number of students who have a pass and have completed the assignment (7), as we don't want to count them twice. Then, we divide the result by the total number of students (43).

Probability = (Number of students with a pass + Number of students who have completed the assignment - Number of students with a pass and have completed the assignment) / Total number of students

Probability = (9 + 18 - 7) / 43

Probability = 20 / 43

To express the probability as a percentage, we multiply the result by 100:

Probability = (20 / 43) × 100 ≈ 46.51%

Therefore, the probability that the first student Mr. Beal selects has a pass or has completed the homework assignment is approximately 46.51%.

We can use the standard normal distribution and z-scores to answer these questions:

P(X > 11.5) = P(Z > (11.5 - 8) / 1.5) = P(Z > 2.33) = 0.0099

Therefore, the probability that a randomly selected mechanical component weighs more than 11.5 lbf is 0.0099, or about 1%.

P(X < 8.7) = P(Z < (8.7 - 8) / 1.5) = P(Z < 0.47) = 0.3208

Therefore, the probability that a randomly selected mechanical component weighs less than 8.7 lbf is 0.3208, or about 32%.

P(X < 5.0) = P(Z < (5 - 8) / 1.5) = P(Z < -2) = 0.0228

Therefore, the probability that a randomly selected mechanical component weighs less than 5.0 lbf is 0.0228, or about 2%.

P(6.2 < X < 7.0) = P((6.2 - 8) / 1.5 < Z < (7 - 8) / 1.5) = P(-1.2 < Z < -0.67) = 0.1314

Therefore, the probability that a randomly selected mechanical component weighs between 6.2 lbf and 7.0 lbf is 0.1314, or about 13%.

P(10.3 < X < 14.0) = P((10.3 - 8) / 1.5 < Z < (14 - 8) / 1.5) = P(1.53 < Z < 2.67) = 0.0436

Therefore, the probability that a randomly selected mechanical component weighs between 10.3 lbf and 14.0 lbf is 0.0436, or about 4%.

P(6.8 < X < 8.9) = P((6.8 - 8) / 1.5 < Z < (8.9 - 8) / 1.5) = P(-0.47 < Z < 0.60) = 0.3464

Therefore, the probability that a randomly selected mechanical component weighs between 6.8 lbf and 8.9 lbf is 0.3464, or about 35%.
