The condition that is not needed for the inference in this case is D) The graph of the sample data is symmetric with no outliers.

While it is generally desirable to have a symmetric distribution without outliers for making statistical inferences, it is not a necessary condition. The central limit theorem states that as the sample size increases, the sampling distribution of the sample mean approaches a normal distribution, regardless of the shape of the population distribution, as long as certain conditions are met (such as random sampling and independence of observations). Therefore, the shape of the sample data distribution and the presence of outliers do not affect the validity of constructing a confidence interval based on the sample mean.

However, the condition that is not needed for the inference is D) The graph of the sample data is symmetric with no outliers. While a symmetric distribution without outliers can make it easier to construct a confidence interval, it is not a necessary condition for inference. The other conditions listed (random sampling, independence, sample size less than 10% of population size, and a large enough sample size) are all necessary for inference.

The expression represents 3 more than x is function f(x) = x + 3. Option D is the correct answer.

The phrase "3 more than x" implies that we need to add 3 to x.

Therefore, the correct expression is option d, which is x + 3.

Option a, 3x, represents three times x, which is not the same as adding 3 to x.

Option b, 3/x, represents 3 divided by x, which is also not the same as adding 3 to x.

Option c, x - 3, represents subtracting 3 from x, which is the opposite of adding 3 to x.

The appropriate measure of center for the data, and what is its value is the median is the best measure of center, and it equals 19.

The appropriate measure of center for the data is the median since the box plot is skewed and there are outliers.

From the box plot, we can see that the line in the box is at 19, which means that 50% of the data falls below 19 and 50% falls above 19. Therefore, the median is the best measure of the center, and its value is 19.

Thus, the correct option is c. The median is the best measure of the center, and it equals 19.

The difference between the area of the triangle and area of the rectangle is 130

The space enclosed by the boundary of a plane figure is called its area. The area of a figure is the number of unit squares that cover the surface of a closed figure. Area is measured in square units like cm² and m². Area of a shape is a two dimensional quantity.

Represent the area of triangle , square and rectangle by x, y, z respectively.

x = 0.2y

z = 0.7y

x+y+z = 494

therefore;

0.2y +y + 0.7y = 494

1.9y = 494

divide both sides by 1.9

y = 494/1.9

y = 260

x = 0.2 ×260

There are 252 distinct ways to dispatch the taxis to the three airports.

We need to find the number of distinct ways in which we can dispatch the taxis to the three airports, given that two taxis go to airport A, six go to airport B, and one goes to airport C.

First, we choose two taxis out of nine to send to airport A. This can be done in C(9, 2) = 36 ways.

Next, we choose six taxis out of the remaining seven to send to airport B. This can be done in C(7, 6) = 7 ways.

Finally, the last taxi is sent to airport C.

Therefore, the total number of distinct ways to dispatch the taxis is:

C(9, 2) x C(7, 6) = 36 x 7 = 252

The percentage of standardized test scores between 420 and 640 is 68.3%, the percentage of standardized test scores less than 420 or greater than 640 is 112.4% and the percentage of standardized test scores greater than 750 is 2.28%.

(a) To calculate what percentage of standardized test scores is between 420 and 640, we need to convert the values into z-scores by using the following formula:z = (x - μ) / σWhere,x = 420, μ = 530 and σ = 110 for the lower boundary.x = 640, μ = 530 and σ = 110 for the upper boundary.Substituting these values into the formula, we get:z₁ = (420 - 530) / 110 = -1.00z₂ = (640 - 530) / 110 = 1.00Thus, the area between z₁ and z₂ is the same as the area between 0 and z₂ minus the area between 0 and z₁, which is given by the standard normal distribution table. Using the standard normal distribution table, we can find the area between 0 and 1.00, which is 0.3413. The area between 0 and -1.00 is also 0.3413. Therefore, the percentage of standardized test scores between 420 and 640 is given by: percentage = (0.3413 + 0.3413) × 100= 68.26 ≈ 68.3%Thus, the required answer is 68.3%. (b) To calculate what percentage of standardized test scores is less than 420 or greater than 640, we need to find the area to the left of 420 and the area to the right of 640. Using the standard normal distribution table, we can find the area to the left of -1.82, which is 0.0344. Therefore, the area to the right of 420 is: area = 1 - 0.0344 = 0.9656Similarly, the area to the right of 640 is: area = 1 - 0.8413 = 0.1587Therefore, the percentage of standardized test scores less than 420 or greater than 640 is given by: percentage = (0.9656 + 0.1587) × 100= 112.43 ≈ 112.4%. Thus, the required answer is 112.4%.

(c) To calculate what percentage of standardized test scores is greater than 750, we need to convert the value into z-score by using the formula:z = (x - μ) / σwhere x = 750, μ = 530, and σ = 110Substituting these values into the formula, we get:z = (750 - 530) / 110= 2.00Using the standard normal distribution table, we can find the area to the right of 2.00, which is 0.0228. Therefore, the percentage of standardized test scores greater than 750 is given by: percentage = 0.0228 × 100= 2.28Thus, the required answer is 2.28%. Therefore, the percentage of standardized test scores between 420 and 640 is 68.3%, the percentage of standardized test scores less than 420 or greater than 640 is 112.4% and the percentage of standardized test scores greater than 750 is 2.28%.

The length of the missing side (the hypotenuse) is 10 ft.

We have,

We can use the Pythagorean theorem to find the length of the missing side of the right triangle.

So,

a² + b² = c²

where a and b are the lengths of the legs, and c is the length of the hypotenuse.

In this case,

The opposite side (which is the leg) has a length of 8 ft, and the adjacent side (which is the other leg) has a length of 6 ft.

Let x be the length of the missing side. Then we have:

a = 8 ft

b = 6 ft

c = x

Plugging these values into the Pythagorean theorem, we get:

8² + 6² = x²

64 + 36 = x²

100 = x²

Taking the square root of both sides, we get:

x = √100 = 10 ft

The rate of filling water in the tank is 23450t gallons per hour.

Let's assume that the time taken to fill the tank is t hours.

The volume of water filled into the tank at time t is given by the expression V(t) = 23450t.

The tank is originally empty, which means its volume = 0 gallons.

After 5 hours,

t= 5 hours

The volume of water filled in is given by \(V(5) = 23450 * 5= 1,17,250\) gallons of water.

The equation for the transformed logarithm that passes through the points (3,0) and (0,2) can be written as f(x) = -b * log(base a)(x - h) + k, where a, b, h, and k are constants to be determined.

To find the equation for the transformed logarithm, we need to use the given points (3,0) and (0,2) to determine the values of a, b, h, and k. Let's start with the point (3,0). Plugging the x-coordinate (3) into the equation, we have:

0 = -b * log(base a)(3 - h) + k

Next, we'll use the point (0,2) to obtain another equation. Plugging the x-coordinate (0) into the equation, we get:

2 = -b * log(base a)(0 - h) + k

Simplifying these equations, we have a system of equations to solve for a, b, h, and k. However, since the equation involves a logarithm, we need more information to determine the specific values of a, b, h, and k.The transformed logarithm function includes transformations such as vertical stretches/compressions (b), horizontal shifts (h), and vertical shifts (k). Without more specific information about these transformations or the base of the logarithm, it is not possible to determine the equation uniquely.

In general, the equation for a transformed logarithm can be written as f(x) = -b * log(base a)(x - h) + k, where a, b, h, and k are constants determined by the specific transformations applied to the logarithm function. It's important to have additional information or instructions to determine the values of a, b, h, and k and provide an equation that accurately represents the given transformed logarithm.

(a) To determine if (S,t) is a yes-instance for S={2,3,5,7,8} and t=19, we need to check if there exists a subset of S whose elements sum to 19. In this case, we can choose the subset T={2,7,10} where the elements sum to 19. Thus, (S,t) is a yes-instance.

(b) A brute force algorithm for the SUBSET SUM problem involves checking all possible subsets of S and calculating their sums to see if any sum equals t. However, the number of possible subsets grows exponentially with the size of S, making the algorithm impractical for larger sets. For example, if S has n elements, the number of subsets is 2^n, which becomes computationally infeasible for large values of n.
(c) The dynamic programming solution presented in the provided link is not a polynomial time algorithm because it still has to consider all possible subsets of S. Although it improves the efficiency by using memoization to avoid redundant calculations, the algorithm's time complexity is still exponential in the worst case. It explores all possible combinations of elements in S to determine if there exists a subset sum equal to t, resulting in a runtime that grows exponentially with the size of S. Thus, it cannot be classified as a polynomial time algorithm.
