1. The probability of selecting exactly one tank with high-viscosity material is 0.

2. The probability of selecting at least one tank with high-viscosity material is 1.

3. The probability of selecting exactly one tank with high-viscosity material and exactly one tank with high impurities is 0.25.

1. The probability of selecting exactly one tank with high-viscosity material is calculated by the binomial distribution formula, P(X = n) = (nCx)p^x(1-p)^n-x, where n is the number of trials, x is the number of successes, and p is the probability of success. In this case, n = 4, x = 1, and p = 24/24 = 1. Therefore, P(X = 1) = (4C1)1^1(1-1)^4-1 = 0.

2. The probability of selecting at least one tank with high-viscosity material is calculated by the complement rule, P(X > 0) = 1 - P(X = 0). In this case, P(X > 0) = 1 - (4C0)1^0(1-1)^4-0 = 1.

3. The probability of selecting exactly one tank with high-viscosity material and exactly one tank with high impurities is calculated by the binomial distribution formula, P(X = n) = (nCx)p^x(1-p)^n-x, where n is the number of trials, x is the number of successes, and p is the probability of success. In this case, n = 8, x = 2, and p = 24/24 = 1. Therefore, P(X = 2) = (8C2)1^2(1-1)^8-2 = 0.25.

Answer: Samantha is 13 years old and Jennifer’s age is 10 years old.

Because it said she was 3 years older, which means 13 +10 = 23.

Step-by-step explanation:

I think.

Samantha age is 7 years and Jennifer age is 4 years.

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.

Variables are the name given to these symbols because they lack set values.

In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

Given:

Samantha is 3 years older than Jennifer.

let Jennifer age be x.

So, Samantha age= x + 3

Now, The square of Jennifer's age plus Samantha's age is equal to 23.

x²+ (x+ 3) = 23

x² + x + 3 = 23

x² + x - 20 = 0

(x- 4) ( x + 5) = 0

x= 4, -5

Hence, Samantha age is 7 years and Jennifer age is 4 years.

The number of arrangements is 277,695,360

Permutations refer to the number of ways in which a set of distinct objects can be arranged or ordered. In other words, permutations are arrangements of objects where the order matters.

Combinations refer to the number of ways in which a subset of objects can be selected from a larger set of objects. Combinations do not consider the order of the selected objects.

Here we have

Arrangements of length 12 formed by different letters (no repetition) chosen from the 26-letter alphabet are there that contain the five vowels (a,e,i,o,u)

First, choose the positions for the five vowels in \($\binom{12}{5}$\) ways.

Then, we need to fill the remaining 7 positions with the 21 consonants, which we can do in \($21^7$\)

Therefore,

The total number of arrangements that contain the five vowels is:

=> \($\binom{12}{5}$\) ×  \($21^7$\) = 277,695,360

Note that this assumes that the five vowels are the only vowels allowed in the arrangement.

If the arrangement can have additional repetitions of the vowels, we would need to adjust the calculation accordingly.

Therefore,

The integral ∫51xg′(x)dx evaluates to -11.5. This result is obtained by applying the fundamental theorem of calculus and using the given information about g(x).

To explain further, let's denote the integral in question as I. According to the fundamental theorem of calculus, if F(x) is an antiderivative of g(x), then ∫abg(x)dx = F(b) - F(a). We are given that ∫51g(x)dx = -9, which implies that the antiderivative of g(x) evaluated from 1 to 5 is -9. Therefore, we have F(5) - F(1) = -9.

Next, we need to find the derivative of xg(x). Applying the product rule, we have (xg(x))' = xg'(x) + g(x). Integrating this expression gives us ∫(xg'(x) + g(x))dx = ∫xg'(x)dx + ∫g(x)dx = xg(x) + F(x).

Now, we can rewrite the integral we are evaluating as ∫51xg′(x)dx = xg(x) + F(x) evaluated from 1 to 5. Plugging in the known values, we have (5g(5) + F(5)) - (1g(1) + F(1)) = (5(-9) + F(5)) - (1(-4) + F(1)) = -45 + F(5) + 4 + F(1) = -41 + F(5) + F(1).

Since the integral of g(x) from 1 to 5 is -9, we have F(5) - F(1) = -9. Substituting this into the previous expression, we get -41 - 9 = -50. Therefore, ∫51xg′(x)dx = -11.5.

Stochastic Gradient Descent is that it does the calculations faster than gradient descent and batch gradient descent that is where stochastic gradient descent preferred over deterministic gradient descent.

One of the most widely used techniques for selecting the model that best fits the training data is gradient descent. Typically, that model is the one that minimizes the loss function, such as in a linear regression by minimizing the Residual Sum of Squares. Stochastic Gradient Descent is a variation on gradient descent that is stochastic, or probabilistic. It performs significantly better in large datasets and fixes Gradient Descent's flaws. It is therefore frequently employed as the optimization algorithm in extensive, online machine learning techniques like Deep Learning. SGD is a method of generalization outside of the training set and is an extension of the gradient descent algorithm.

The cost of direct labor per unit is $5.628 per apple.

To calculate the cost of direct labor per unit, we need to determine the total labor hours required to produce one unit of output and then multiply it by the wage rate.

Let's denote the labor hours required for the first resource as "L₁" and the labor hours required for the second resource as "L₂".

The first resource has a capacity of 2.1 apples per hour, and the demand is 1.6 apples per hour. Therefore, the labor hours required for the first resource per unit of output are:

L₁ = 1 apple / (2.1 apples/hour) = 0.4762 hours/apple (rounded to 4 decimal places)

The second resource has a capacity of 4.4 apples per hour, and the demand is 1.6 apples per hour. Therefore, the labor hours required for the second resource per unit of output are:

L₂ = 1 apple / (4.4 apples/hour) = 0.2273 hours/apple (rounded to 4 decimal places)

Now, let's calculate the total labor hours required per unit:

Total labor hours per unit = L₁ (first resource) + L₂ (second resource)

= 0.4762 hours/apple + 0.2273 hours/apple

= 0.7035 hours/apple (rounded to 4 decimal places)

Finally, to calculate the cost of direct labor per unit, we multiply the total labor hours per unit by the wage rate:

Cost of direct labor per unit = Total labor hours per unit * Wage rate

= 0.7035 hours/apple * $8/hour

= $5.628 per apple (rounded to 3 decimal places)

In order to solve the system of equations, let's equate both values of y and solve for x using the quadratic formula:

Now, let's calculate the values of y for each value of x:

Therefore the solutions are (1, 7) and (5/2, 10).

Correct option: second one.

The point on the y-axis that lies on the line passing through point g and is parallel to line df is (0, -slope of df * xg + yg).

To find the point on the y-axis that lies on the line passing through point g and is parallel to line df, we first need to determine the slope of line df. Once we have the slope, we can find the slope of the line passing through point g and parallel to line df. Then, we can use point-slope form to write the equation of this line and solve for the y-intercept, which will give us the point on the y-axis that we are looking for.

Assuming that the coordinates of point g and the endpoints of line df are given, we can find the slope of line df using the slope formula:

slope of df = (y2 - y1) / (x2 - x1)

where (x1, y1) and (x2, y2) are the coordinates of the endpoints of line df.

Next, since the line passing through point g is parallel to line df, it will have the same slope as line df. So we can use the slope we just found to write the equation of the line passing through point g:

(y - yg) = slope of df * (x - xg)

where (xg, yg) are the coordinates of point g.

Now we can solve for the y-intercept by setting x = 0 (since we want the point on the y-axis):

(y - yg) = slope of df * (0 - xg)
y - yg = -slope of df * xg
y = -slope of df * xg + yg

So the point on the y-axis that lies on the line passing through point g and is parallel to line df is (0, -slope of df * xg + yg).

c) Expected value of X  = -0.5

d) the stake of the gambler in  order to make this a fair game is $0.5

What is probability?

Probability gives us the information about how likely an event is going to occur

Probability is calculated by Number of favourable outcomes divided by the total number of outcomes.

Probality of any event is greater than or equal to zero and less than or equal to 1.

Probability of sure event is 1 and probability of unsure event is 0.

a) Let a number n be chosen between 1 and 6

Three fair six sided dice are thrown

The following cases can occur

1) Number n occur on none of the three dice

2) Number n occur on one dice

3) Number n occur on two dice

4) Number n occur on three dice

3) X = 2 - 1 = 1

4) X = 3 - 1 = 2

State space S(x) = {-1, 0, 1, 2}

b) P(X = -1) = \({3 \choose 0}(\frac{1}{6})^0(\frac{5}{6})^3 = (\frac{5}{6})^3 = \frac{125}{216}\)

    P(X = 0) = \({3 \choose 1})(\frac{1}{6})(\frac{5}{6})^2 = \frac{25}{72}\)

    P(X = 1) = \({3 \choose 2}(\frac{1}{6})^2\frac{5}{6} = \frac{5}{72}\)

    P(X = 2) = \({3 \choose 3}(\frac{1}{6})^3(\frac{5}{6})^0 = \frac{1}{216}\)

    The required probability mass function is

    P(X = -1) = \(\frac{125}{216}\)

    P(X = 0)  \(= \frac{25}{72}\)

    P(X = 1)  \(= \frac{5}{72}\)

    P(X = 2)  \(= \frac{1}{216}\)

c) Expected value of X = \(-1 \times \frac{125}{216} + 0 \times \frac{25}{72} + 1 \times \frac{5}{72} + 2\times \frac{1}{216}\)

                                      = \(\frac{-125 + 0 + 15 +2}{216}\\\)

                                      = \(-\frac{108}{125}\)
