When r = 3, q = 1, and w = -2, the expression 8 + |q - 5| evaluates to 12.

Let's evaluate the given expression step by step.

First, we have |q - 5|. Substituting q = 1 into the expression, we have |1 - 5|. The absolute value of (1 - 5) is 4.

Next, we add 8 to the absolute value of (q - 5): 8 + 4 = 12.

Therefore, when r = 3, q = 1, and w = -2, the expression 8 + |q - 5| evaluates to 12.

In this case, the values of r and w are not used in the expression, so their values do not affect the result. Only the value of q = 1 is used to evaluate the absolute value portion of the expression.Hence, regardless of the values of r and w, the final evaluation of the expression is 12 when q = 1.

If a red ball is drawn at random from one of the urns, there is a higher probability (2/3) or 0.667 that it came from Urn A rather than Urn B. This suggests that Urn A is more likely to be the source of the red ball.

To calculate the probability that Urn A was chosen given that a red ball was drawn, we can use Bayes' theorem.

Let's denote the events:

A = Urn A was chosen

B = Urn B was chosen

R = A red ball was drawn

We want to find P(A|R), the probability that Urn A was chosen given that a red ball was drawn.

According to Bayes' theorem:

P(A|R) = (P(R|A) * P(A)) / P(R)

P(R|A) is the probability of drawing a red ball given that Urn A was chosen. Since Urn A has four red balls and four black balls, the probability of drawing a red ball from Urn A is 4/8 = 1/2.

P(A) is the prior probability of choosing Urn A, which is 0.5 since there is an equal chance of selecting either Urn A or B.

P(R) is the overall probability of drawing a red ball, which can be calculated by considering all possible scenarios:

P(R) = P(R|A) * P(A) + P(R|B) * P(B)

P(R|B) is the probability of drawing a red ball given that Urn B was chosen. Since Urn B has two red balls and six black balls, the probability of drawing a red ball from Urn B is 2/8 = 1/4.

P(B) is the prior probability of choosing Urn B, which is also 0.5.

Substituting the values into the equation:

P(R) = (1/2) * (1/2) + (1/4) * (1/2) = 3/8

Now we can calculate P(A|R) using Bayes' theorem:

P(A|R) = (P(R|A) * P(A)) / P(R) = (1/2 * 1/2) / (3/8) = 4/6 = 2/3

Therefore, the probability that Urn A was chosen given that a red ball was drawn is 2/3 or approximately 0.667.

In conclusion, if a red ball is drawn at random from one of the urns, there is a higher probability (2/3) that it came from Urn A rather than Urn B. This suggests that Urn A is more likely to be the source of the red ball.

The probability of the following parts is: a. 0.33 b. 1.925 c. 0.176 d. 0.67 e. 0.99955416 f. 0.018318006 g. 0.4489

a. To find out the probability that none of the first three people is concerned about their credit scores, we need to find: P(none of the first three is concerned about their credit scores)we have been given the probability that a teenager is concerned about his/her credit score is 0.67. So the probability that a teenager is not concerned about his/her credit score is 0.33. Now we can say that this is a binomial distribution since we are repeating a procedure until success is achieved. So we can use the binomial distribution to find the above probability: P(none of the first three are concerned about their credit scores) = (0.33)^3 = 0.0359375

b. The expected value of X is given by: E(X) = 1/p = 1/0.67 = 1.4925

c. Variance of X is given by: Var(X) = (1-p)/p^2 = (0.33)/(0.67)^2 = 0.176

d. Since X is the number of teenagers we select who are not concerned about their credit scores before we find the first teenager who is concerned. The probability that X = 0 is the probability that the first teenager we select is concerned about his/her credit score, which is given by: P(X = 0) = p = 0.67

e. To find out the probability that X ≤ 4, we can use the complement rule: P(X ≤ 4) = 1 - P(X > 4) = 1 - [P(X = 5) + P(X = 6) + ....... to ∞] = 1 - (1 - p)^5 = 1 - (0.33)^5 = 0.99955416

f. To find out the probability that Y = 6, we need to find: P(Y = 6)We know that for Y = 6, we need to select 7 teenagers such that the first and the second teenager we select are not concerned about their credit scores, and the third to the seventh teenager we select are concerned about their credit scores. The probability that the first and the second teenager we select are not concerned about their credit scores is given by: P(selecting 2 teenagers not concerned about their credit scores) = (0.33)^2 = 0.1089 And the probability that the third to the seventh teenager we select are concerned about their credit scores is:

P(selecting 5 teenagers concerned about their credit scores) = (0.67)^5 = 0.16806957Therefore, P(Y = 6) = P(selecting 2 teenagers not concerned about their credit scores) * P(selecting 5 teenagers concerned about their credit scores) = 0.018318006

g. To find out the probability that Y = 0, we need to select the first two teenagers who are concerned about their credit scores. P(Y = 0) = P(selecting the first two teenagers who are concerned about their credit scores) = (0.67)^2 = 0.4489.

The weights of the cartons of raspberries picked by the students are:

To complete the table, on the first column you have to write each observed weight, those are: 1/4, 2/4, 3/4, and 4/4

Then, on the second column, you have to write one tally, for each box that has the said weight.

For example, for the weight 1/4 pounds, there are three boxes that weighed 1/4pounds, so you have to write three tallies.

For "2/4 pounds", there were 2 boxes that had this weight, so you have to write two tallies.

For "3/4" pounds, there were 3 boxes that had this weight, so you have to write three tallies.

For "4/4 pounds", there was only one box that measures this weight, so you have to write one tally.

For the number line, you have to make a "dot plot", below the line you have to write each possible weight: 1/4, 2/4, 3/4, and 4/4. Then you have to draw points above each weight, one for each box that measured the said weight:

The chi-square distribution provides a good approximation to the sampling distribution of the chi-square statistic if the expected frequency in each cell is at least 5.

The chi-square statistic is a measure of how different an observed frequency is from the expected frequency. It is calculated by taking the difference between the observed and expected frequency in each cell, squaring it, and then summing the results. This measure can then be compared to a chi-square distribution with degrees of freedom equal to the number of cells minus one. If the calculated statistic is larger than the expected value from the chi-square distribution, then it can be concluded that the observed frequency differs significantly from the expected frequency.
In order to use the chi-square approximation, it is important that the expected frequency in each cell is at least 5. This is because the chi-square approximation only works well when there are large expected frequencies. When expected frequencies are smaller than 5, the chi-square statistic is not an accurate measure of the difference between the observed and expected frequencies.

Answer:

A = $150

B = $130

C = $140

Step-by-step explanation:

Let the amount received by a be $x

b receives $20 less than a;

we have that;

b = x - 20

c receives half of Sum A and B

c = (x + x-20)/2

c = (2x-20)/2

c = x - 10

Add all and it gives 420

x - 10 + x -20 + x = 420

3x -30 = 420

3x = 420 + 30

3x = 450

x = 450/3

x =$150

a = 150

b = x - 20; 150 - 20 = 130

c = x-10

c = 150-10

c = $140

The probability that the mean of the sample will be less than 35 is approximately 0.0205, or 2.05%.

To solve this problem, we'll use the central limit theorem, which states that for a large enough sample size, the distribution of sample means approximates a normal distribution, regardless of the shape of the population distribution.

Given that the population follows a uniform distribution with α = 24 and β = 48, we know that the mean (μ) of the population is given by the formula:

μ = (α + β) / 2

Substituting the values, we have:

μ = (24 + 48) / 2 = 72 / 2 = 36

The standard deviation (σ) of the population is given by the formula:

σ = (β - α) / √12

Substituting the values, we have:

σ = (48 - 24) / √12 = 24 / √12 = 24 / 3.464 = 6.928

According to the central limit theorem, the distribution of sample means follows a normal distribution with a mean equal to the population mean (μ) and a standard deviation equal to the population standard deviation (σ) divided by the square root of the sample size (n). Therefore:

μ_s = μ = 36

σ_s = σ / √n = 6.928 / √200 ≈ 0.490

To find the probability that the mean of the sample will be less than 35, we need to find the area under the normal distribution curve to the left of 35. We'll use a standard normal distribution with a mean of 0 and a standard deviation of 1, and then transform it using the mean and standard deviation of the sample distribution.

Let's calculate the z-score for 35:

z = (x - μ_s) / σ_s = (35 - 36) / 0.490 ≈ -2.041

Using a standard normal distribution table or a calculator, we can find the probability corresponding to a z-score of -2.041. The probability that the mean of the sample will be less than 35 is approximately 0.0205, or 2.05%.

Answer:

45

Step-by-step explanation:

A number consists of 2 digits whose sum is 9 => x + y = 9

If the order of the numbers is inverted, the result is equal to the given number plus 9 units => (10*y + x) + 9 = (10*x + y)

Thus:

x + y = 9  => multiply by -9 => 9*y + 9*x = 81

10*y + x + 9 = 10*x + y =>  9*y - 9*x = -9

We are left then that:

9*y + 9*x = 81  (1)

9*y - 9*x = -9  (2)

we add both equations

18y = 72

y = 72/18 = 4

replacing

x + y = 9

x + 4 = 9

x = 5

Therefore the number is (10y + x) => (10 * 4 + 5) => 45

To show that (X,T) is a subspace of (Z,T**), we must show that (X,T) satisfies the subspace axioms. The subspace axioms that must be satisfied are:

1. The zero vector, 0, is in (X,T).

2. If u and v are in (X,T), then u + v is also in (X,T).

As given by the question , so here the vertical and horizontal asymptotes are at x = -12 and y = 1.5.

On a function graph, a vertical asymptote represents the point at which the function is undefined. Take the formula f(x) = 1/x as an illustration. This function's graph exhibits a vertical asymptote at x = 0 since the function is undefined at this value (division by 0 is undefined).

A function's horizontal asymptote is a horizontal line on the function graph that the function approaches as the input (x-value) increases or decreases dramatically. Consider the function f(x) = x2 as an illustration. Because the y-values of the function do not converge to a fixed value as x grows very big, the graph of this function lacks a horizontal asymptote.

We must identify the values of x at which the function is undefined in order to determine the vertical asymptotes of the function 3x/(2x+24).So, to find the vertical asymptotes of the function, we need to solve the equation 2x + 24 = 0 for x. so x = -12.

Similarly, To find the horizontal asymptote in case of equal degrees of numerator and denominator i.e 1 in this case, we need to take the ratio of the first coefficients of numerator and denominator respectively which is 3/2 = 1.5.

v = 18

Answer: V=18

Step-by-step explanation:

PEMDAS can be used to solve this problem. PEMDAS stands for parentheses, exponents, multiplication, division, addition, and subtraction. You see that there are no parentheses, exponents, or multiplication/division steps so you have addition left. To solve 26=8+v, you have to isolate the variable by subtracting the 8 on both sides of the equation. 26-8 is 18, so, the final equation is v=18.

This is the solution to the initial value problem \(y'/x = 1/(y^2 - y),\) passing through the point (1, 2).

To find the solution of the given initial value problem, we can separate variables and integrate both sides. Let's start with the given differential equation:

\(y'/x = 1/(y^2 - y)\)

Rearranging the equation, we have:

\((y^2 - y) dy = x dx\)

Now, we integrate both sides:

∫ \((y^2 - y) dy\) = ∫ x dx

Integrating the left side with respect to y:

∫\((y^2 - y) dy = (1/3) y^3 - (1/2) y^2 + C1\)

Integrating the right side with respect to x:

∫ \(x dx = (1/2) x^2 + C\)

where C1 and C2 are constants of integration.

Now, we can apply the initial condition (1, 2) to find the specific values of C1 and C2. Substituting x = 1 and y = 2 into the equation:

\((1/3)(2)^3 - (1/2)(2)^2 + C1 = (1/2)(1)^2 + C2\)

(8/3) - 2 + C1 = 1/2 + C2

C1 - 2/3 = 1/2 + C2

C1 = 1/2 + C2 + 2/3

C1 = (3/6 + 2/6 + 4/6) + C2

C1 = 9/6 + C2

C1 = 3/2 + C2

Now, we substitute C1 = 3/2 + C2 back into the solution equation:

\((1/3) y^3 - (1/2) y^2 + (3/2 + C2) = (1/2) x^2 + C2\)

Simplifying, we have:

\((1/3) y^3 - (1/2) y^2 + (3/2) = (1/2) x^2\)
