The probability that she is taking a night class = 0.437

According to the information given in the question,

We will be using the concept of Conditional Probability,

According to conditional probability, any event A is determined and derived keeping in mind that the second event B has already occurred.

Seeing the data given in the question,

Now if we see that the total number of sections per day is 7 we could derive that,

⇒ The sections were taken by part-time faculty = Total sections held in a day x % part-time faculty + sections in night class x % part-time faculty.

The sections were taken by part-time faculty = (5 x 40%) + (2 x 60%)

= 2 + 1.2

= 3.2

⇒ Now to calculate the probability of sections taken by the part-time faculty,

P = \(\frac{Number\ of\ sections \ by\ part-time \ faculty}{Total \ number\ of sections\ in\ a\ day }\)

P = \(\frac{3.2}{7}\)

P = 0.457

⇒ The probability that the sections are taken at night and by the part-time faculty = Probability of night section x % of sections taken by part-time faculty.

= \(\frac{2}{6} * 60\) %

= 0.20

⇒ Now the Probability that the class is taken part-time.

=  \(\frac{Probability\ that\ the\ sections\ are\ taken\ at\ night\ and\ by\ the\ part-time\ faculty}{ Probability\ that\ the\ night\ classes\ are\ taken\ by\ part-time\ faculty}\)

= \(\frac{0.20}{0.457}\)

= 0.437

Step-by-step explanation: We can add this in a very easy way.

Step 1- We can put the 1 in the ones place as if there is no number before a decimal (which is the case for the first number) we can assume it is 0.

Step 2- We can then place the decimal point after the 1 and then put 0.8 since there are no more numbers that are at the tenths

Step 3- At the end we add the .04 (also known as 0.04) as there are no more places in both the numbers that are in the hundredths (and in 1.8, it can also be known as 1.80 as there are none!)

∫(0 to π/2) ∫(0 to sqrt(4-z)) ∫(0 to 4-r²) 9(r³*cos(θ)³ + r³*cos(θ)*sin(θ)²)r dr dθ dz. By solving this triple integral, we'll find the value of the given expression in cylindrical coordinates.

To evaluate the given integral in cylindrical coordinates, we first need to convert the given expression and region of integration from Cartesian coordinates to cylindrical coordinates. In cylindrical coordinates, we have x = r*cos(θ), y = r*sin(θ), and z = z. The given expression becomes:

9(x³ + xy²)dV = 9(r³*cos(θ)³ + r³*cos(θ)*sin(θ)²)r dr dθ dz

Now, let's find the bounds of integration for the solid E. Since it lies in the first octant and beneath the paraboloid z = 4 - x² - y², we have:

0 ≤ z ≤ 4 - r²*cos(θ)² - r²*sin(θ)²
0 ≤ r ≤ sqrt(4 - z)
0 ≤ θ ≤ π/2

Now we can set up and evaluate the integral:

The metric unit that would be best to measure the capacity of a cereal bowl is milliliters (ml).

Capacity is a measure of the amount of fluid that a container can hold. Cereal bowls are typically used to hold liquids such as milk or yogurt along with cereal. Milliliters are a commonly used metric unit of volume that would be appropriate for measuring the capacity of a cereal bowl. Other metric units of volume such as liters or cubic centimeters could also be used, but milliliters would provide a more precise measurement for a smaller container such as a cereal bowl. To measure the capacity of a cereal bowl in milliliters, one would simply pour a known amount of water into the bowl and measure the volume of the water using a measuring cup or a graduated cylinder.

Given the following trinomial:

Since the given trinomial is quadratic, there are two factors in this equation.

Step 1: Determine the factors of the first term, 2x².

There are no other possible factors of 2x² but 2x and x.

Therefore, we can now generate the initial factors.

Let A and B represent the unknown constants of the factors to be able to get the product of 2x² + 7x + 4.

Step 2: Let's determine A and B.

Let's think of possible constants of A and B that have a product of 4 and a sum of 7x when adding A multiplied by x and B multiplied by 2x.

Let's list down possible pairs.

TABLE

Sum of 4 (A and B) Sum of 7x

1 and 4 1(x) + 4(2x) = x + 8x = 9x

2 and 2 (2)(x) + 2(2x) = 2x + 4x = 6x

4 and 1 4(x) + 1(2x) = 4x + 2x = 6x

-1 and -4 -1(x) - 4(2x) = -x - 8x = -9x

-4 and -1 -4(x) - 1(2x) = -4x - 2x = -6x

None of the possible factors are possible to complete the equation, therefore, we can say that the given trinomial is not a perfect square and is not factorable.

If we are tasked to factor the trinomial by completing the square, we get:

The constant must be 3 and not 4 for it to be factorable and will

The margin of error for the 95% confidence interval used to estimate the population proportion, given n = 186 and x = 103, is approximately 0.0643 (option b).

To find the margin of error for a confidence interval, we use the formula:

Margin of Error = \(Z * \sqrt{((p-hat * (1 - p-hat)) / n)}\),

where Z represents the z-score corresponding to the desired confidence level, p-hat is the sample proportion, and n is the sample size.

In this case, the sample size is n = 186 and the sample proportion is p-hat = x/n = 103/186.

First, we need to find the z-score corresponding to a 95% confidence level. The z-score for a 95% confidence level is approximately 1.96.

Substituting the values into the formula, we have:

Margin of Error = \(1.96 * \sqrt{ ((103/186 * (1 - 103/186)) / 186)}\) ≈ 0.0643.

Therefore, the margin of error for the 95% confidence interval is approximately 0.0643 (option b).

The root of the equation sinx = 2x-3 is 0.8401 (approx).

Given equation is sinx = 2x-3

We need to solve this equation using false position method.

False position method is also known as the regula falsi method.

It is an iterative method used to solve nonlinear equations.

The method is based on the intermediate value theorem.

False position method is a modified version of the bisection method.

The following steps are followed to solve the given equation using the false position method:

1. We will take the end points of the interval a and b in such a way that f(a) and f(b) have opposite signs.

Here, f(x) = sinx - 2x + 3.

2. Calculate the value of c using the following formula: c = [(a*f(b)) - (b*f(a))] / (f(b) - f(a))

3. Evaluate the function at point c and find the sign of f(c).

4. If f(c) is positive, then the root lies between a and c. So, we replace b with c. If f(c) is negative, then the root lies between c and b. So, we replace a with c.

5. Repeat the steps 2 to 4 until we obtain the required accuracy.

Let's solve the given equation using the false position method.

We will take a = 0 and b = 1 because f(0) = 3 and f(1) = -0.1585 have opposite signs.

So, the root lies between 0 and 1.

The sum of the series is 64. In conclusion, the geometric series 8 + 7 + 49/8 + 343/64 + ... is convergent, and its sum is 64.

To determine if the geometric series is convergent or divergent, we need to check if the ratio between each term and its previous term is constant. In this series, the ratio between each term and its previous term is 7/8, which is less than 1. This means that the series is convergent.

To find the sum of the series, we can use the formula S = a / (1 - r), where S is the sum, a is the first term, and r is the ratio. In this case, a = 8 and r = 7/8, so:

S = 8 / (1 - 7/8)
S = 8 / (1/8)
S = 64

Therefore, the sum of the series is 64. In conclusion, the geometric series 8 + 7 + 49/8 + 343/64 + ... is convergent, and its sum is 64.

Step-by-step explanation:

The net force acting on the object is 3456 N, the objective with an acceleration.

The net force applied to an object is equal to the product of its mass and acceleration, according to Newton's second law of motion. Mathematically, this can be represented as:

Fnet = ma

Where Fnet is the net force, m is the mass, and a is the acceleration. In your scenario, the net force applied to the object is 125 N, and its acceleration is 24.0 m/s2. Therefore, we can rearrange the formula and solve for the mass of the object as follows:

m = Fnet / a
m = 125 N / 24.0 m/s2
m = 5.21 kg

However, this answer does not match the given mass of the object, which is 144 kg. This suggests that there may be an error in one of the values provided. Assuming the mass of the object is actually 144 kg, we can use the same formula to solve for the net force acting on it as follows:

Fnet = ma
Fnet = 144 kg * 24.0 m/s2
Fnet = 3456 N

The mass of an object with net force value = 125 Newton and acceleration of 24.0 m/s² is equals to the 5.208 kg. So, option(c) is right one.

The force formula is derived by Newton's second law of motion. The basic formula force applied on object is F = ma, which implies that net force is equals to product of mass and acceleration of an object. We have an object with the following information, Net applied force on object, F = 125 N

Acceleration of an object, a = 24.0 m/s²

We have to determine mass of object. Using the above force formula, F = M× a

where M --> mass in kilograms

a --> Acceleration in m/s²

F --> net force in Newton

Substitute all known values in above formula, 125 N = M × 24.0 m/s²
