Step-by-step explanation:

Answer:

\(\frac{x+18}{x+8}\)

Step-by-step explanation:

Assuming you require the simplification.

Given

\(\frac{x^2+16x-36}{x^2+6x-16}\) ← factorise numerator and denominator

= \(\frac{(x+18)(x-2)}{(x+8)(x-2)}\) ← cancel the common factor (x - 2)

= \(\frac{x+18}{x+8}\)

The null hypothesis is that there is no significant difference between the mean blood pressure of rats with high capacity for exercise and rats with low capacity for exercise. The alternative hypothesis is that rats with low capacity for exercise tend to have a higher blood pressure than rats with high capacity for exercise.

This is the preferred alternative hypothesis for this kind of test because it is a one-tailed test with a directional hypothesis, indicating that we are specifically interested in whether the mean blood pressure of low-capacity rats is higher than that of high-capacity rats.

Therefore, the null hypothesis can be written as H0: μhc = μlc, and the alternative hypothesis can be written as Ha: μlc > μhc.

By choosing some items from a set and creating subsets, permutation and combination are two approaches to represent a group of objects. It outlines the numerous configurations for a particular set of data.

Permutations are the selection of data or objects from a set, whereas combinations are the order in which they are represented. Both ideas are critical to mathematics.

Contrary to permutations, the order of selection is irrelevant when choosing elements from a collection using the combination method. The number of combinations can be counted in simpler situations. Combination is the taking together of n items, k at a time, without repetition.

If you want to round a number within an arithmetic expression, you should use the ROUND function.

The ROUND function allows you to specify the number of decimal places to which you want to round a given number. It is commonly used in programming languages and spreadsheet software.

The syntax for the ROUND function typically involves specifying the number or expression you want to round and the number of decimal places to round to. For example, if you want to round a number, let's say 3.14159, to two decimal places, you would use the ROUND function like this: ROUND(3.14159, 2), which would result in 3.14.

Using the ROUND function ensures that the rounded number is calculated within the arithmetic expression, providing the desired level of precision in the calculation.

To calculate the value of c in the coordinates [a, b, c] for polynomial p(x) = 3x with respect to the basis B = {x + 7x^2, 2 + x, x^2}, we need to find the representation of p(x) in terms of the basis vectors.

Let's denote the basis vectors as b1 = x + 7x^2, b2 = 2 + x, and b3 = x^2.

To express p(x) as a linear combination of the basis vectors, we set up the following equation:

p(x) = a * b1 + b * b2 + c * b3

Substituting the values of p(x) and the basis vectors, we have:

3x = a(x + 7x^2) + b(2 + x) + c(x^2)

Expanding and rearranging terms, we get:

3x = ax + 7ax^2 + 2b + bx + cx^2

Comparing the coefficients of the like terms on both sides of the equation, we can determine the values of a, b, and c.

From the coefficient of x, we have:

a + b = 3 (coefficient of x on the right-hand side)

From the coefficient of x^2, we have:

7a + c = 0 (coefficient of x^2 on the right-hand side)

From the constant term, we have:

2b = 0 (constant term on the right-hand side)

Solving these equations, we find that b = 0, a = 3, and c = -7a = -7 * 3 = -21.

Therefore, the value of c is -21.

The total number of sides of the given polygon is 16.

What is the interior and exterior angle of a regular polygon?

In a regular polygon, all internal angles and exterior angles are equal. The formula for determining the amount of an interior angle is given:

Interior angle of a polygon = sum of interior angles/number of sides  

A polygon's exterior angles add up to 360°.

Given, each interior angle of a regular polygon = 157.5°

Then, each exterior angle of a regular polygon = 180° - 157.5° = 22.5°

the sum of the exterior angles of any n-gon = 360°

So, the total number of sides = 360°/22.5° = 16 sides

Hence, the total number of sides of the polygon is 16.

The probability that the sample mean will be less than 9.10 ounces falls within the range of .0000 to .0500.

To find the probability that the sample mean will be less than 9.10 ounces, we need to use the Central Limit Theorem. Given that the sample size is large (n = 25) and assuming that the population is normally distributed, the sampling distribution of the sample mean will also be normally distributed.

To calculate the probability, we need to standardize the sample mean using the formula z = (x - μ) / (σ / √n), where x is the sample mean, μ is the population mean, σ is the population standard deviation, and n is the sample size.

Since the population mean and standard deviation are not provided, we cannot determine the exact probability. However, we can still indicate the interval that includes the probability.

Based on the given answer choices, the appropriate interval that includes the probability would be .0000 to .0500, as it represents the lowest range of probabilities.

In conclusion, the probability that the sample mean will be less than 9.10 ounces falls within the range of .0000 to .0500.

Triangle ABC is congruent to triangle DFE.

In this triangle, the product of tan A and tan C is `(BC)^2/(AB)^2`.

The given triangle ABC has angle A measuring 45 degrees, angle B measuring 90 degrees, and angle C measuring 45 degrees , Answer: `(BC)^2/(AB)^2`.

We have to find the product of tan A and tan C.

In triangle ABC, tan A and tan C are equal as the opposite and adjacent sides of angles A and C are the same.

So, we have, tan A = tan C

Therefore, the product of tan A and tan C will be equal to (tan A)^2 or (tan C)^2.

Using the formula of tan: tan A = opposite/adjacent=BC/A Band, tan C = opposite/adjacent=AB/BC.

Thus, tan A = BC/AB tan C = AB/BC Taking the ratio of these two equations, we have: tan A/tan C = BC/AB ÷ AB/BC Tan A * tan C = BC^2/AB^2So, the product of tan A and tan C is equal to `(BC)^2/(AB)^2`.

Answer: `(BC)^2/(AB)^2`.

Based on the  calculation done, one can't have a negative number, thus, the regular polygon does not exist.

For a regular polygon of N sides, the measure of each interior angle is:A = (N - 2)*180/N

Here we want to have an interior angle of 220°, then we need to solve the equation:220° =  (N - 2)*180/N

For N, so let's do that: N*220° = (N - 2)*180°We can see that this equation has no solution for N integer:

N*220° = N*180° - 360°N*220° - N*180° = -360°N*40° = -360°N = -360°/40° = -9

We are given a set of vectors S and we need to determine whether each given vector can be written as a linear combination of the vectors in S.

(a) For vector (2, -1, -2), we need to check if there exist scalars k₁ and k₂ such that k₁(2, -1, 3) + k₂(5, 0, 4) = (2, -1, -2). By solving the system of equations, we find that k₁ = -1 and k₂ = 0, so the vector can be written as a linear combination of the vectors in S.

(b) For vector (8, -14, 27/4), we need to check if there exist scalars k₁ and k₂ such that k₁(2, -1, 3) + k₂(5, 0, 4) = (8, -14, 27/4). By solving the system of equations, we find that there are no solutions, so the vector cannot be written as a linear combination of the vectors in S.

(c) For vector (1, -8, 12), we need to check if there exist scalars k₁ and k₂ such that k₁(2, -1, 3) + k₂(5, 0, 4) = (1, -8, 12). By solving the system of equations, we find that there are no solutions, so the vector cannot be written as a linear combination of the vectors in S.

(d) For vector (1, 1, -1), we need to check if there exist scalars k₁ and k₂ such that k₁(2, -1, 3) + k₂(5, 0, 4) = (1, 1, -1). By solving the system of equations, we find that there are no solutions, so the vector cannot be written as a linear combination of the vectors in S.
