Answer:

median - 28

mean - 26.6 (6 repeating)

range - 27

Step-by-step explanation:

The elephant ages would go in the order of 14, 19, 20, 21, 28, 28, 33, 36, 41. To find the median, you need to look for the center of the numbers, which would be 28, since 28 is the middle number. To find the mean, you add all the numbers up and divide them by however many numbers there are, in this case, they add up to 240, and there is 9 numbers, so you would do 240 divided by 9 = 26.66 (repeating so a line over the 6's after the decimal) and to find the range you subtract the highest number and the lowest, which is 41 and 14 and that would give you 27.

LaTisha's calculation of the distance for the brake anchor placement is incorrect because she didn't take into account the height at which the cable is attached to the starting tree.

The bungee cord is attached 16 feet above the ground, which will also contribute to the length of the cable needed to reach the ending tree.

To correctly calculate the distance, we can use the Pythagorean theorem, considering the height (16 feet) and the length of the stretched bungee cord (24 feet + 18 feet = 42 feet). Let's denote the horizontal distance from the base of the ending tree to the brake anchor as 'd'. We have:

d² + 16² = 42²

Now, we can solve for d:

d² + 256 = 1764

d² = 1508

d = √1508 = 38.8 feet (rounded to one decimal place)

The brake anchor should be placed approximately 38.8 feet from the base of the ending tree.

Answer:

$10,244.14 after 12 years

Step-by-step explanation:

To solve this problem, we can use the formula for compound interest:

A = P(1 + r/n)^(n*t)

A = the final amount of the investment

P = the principal amount ($4200 in this case)

r = the annual interest rate (8% or 0.08 as a decimal)

n = the number of times the interest is compounded per year (once annually in this case)

t = the number of years the money is invested (12 years in this case)

Substituting the given values into the formula, we get:

A = 4200(1 + 0.08/1)^(1*12)

A = 4200(1.08)^12

A = 4200(2.44140625)

A = $10,244.14 (rounded to the nearest cent)

a) The length of the hypotenuse AB is 15.

b) The angle ∠A is approximately 53 degrees.

c) The angle ∠C is 90 degrees.

d) The angle ∠B is approximately 37 degrees.

a) To find the length of the hypotenuse AB, we can use the Pythagorean theorem, which states that in a right triangle, the sum of the squares of the legs is equal to the square of the hypotenuse. In this case, we have:

AB² = AC² + CB²

AB² = 12² + 9²

AB² = 144 + 81

AB² = 225

AB = √225

AB = 15

Therefore, the length of the hypotenuse AB is 15.

b) To find the angle ∠A, we can use trigonometry. The sine of an angle is the ratio of the opposite side to the hypotenuse. In this case, we have:

sin(∠A) = AC/AB

sin(∠A) = 12/15

sin(∠A) = 0.8

Taking the inverse sine of 0.8, we get:

∠A = sin⁻¹(0.8)

∠A ≈ 53

Therefore, the angle ∠A is approximately 53 degrees.

c) Since angle ∠C is the right angle, its measure is 90 degrees.

d) To find the angle ∠B, we can use the fact that the sum of the angles in a triangle is 180 degrees. Therefore:

∠B = 180 - ∠A - ∠C

∠B = 180 - 53 - 90

∠B ≈ 37

Therefore, the angle ∠B is approximately 37 degrees.

Yes, a normal distribution can be used to approximate the distribution of the random variable X, which counts the number of adults who have not visited a dentist in the last two years. This approximation can be done using the Central Limit Theorem (CLT), which states that if you have a large enough sample size, the distribution of the sample means will approach a normal distribution, regardless of the original distribution's shape.

To use a normal distribution for this approximation, you need to meet the following criteria:

1. The sample size (n) should be large enough, typically n > 30.
2. The random variable X should have a known mean (μ) and standard deviation (σ).

If these criteria are met, you can use the normal distribution to approximate the distribution of X by calculating the standard error (SE), which is equal to σ / √n. This will help you estimate probabilities and analyze the data for the number of adults who have not visited a dentist in the last two years.

In summary, using a normal distribution to approximate the distribution of the random variable X is possible through the Central Limit Theorem, as long as the sample size is large enough and the mean and standard deviation are known.

The rate of change for the function f(x) is 9.5 over the interval.

How I calculated the rate of change for f(x):

f(2) = 12, f(6) = 50

slope = (50 - 12) / (6 - 2) = 9.5

The rate of change for the function g(x) is -2 over the interval.

How I calculated the rate of change for g(x):

g(2) = -10, g(6) = -18

slope = (-18 - (-10)) / (6 - 2) = -2

To find the rate of change for a function over an interval, we need to calculate the slope of the secant line that connects the two endpoints of the interval.

The slope of a line can be found using the formula:

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

For the quadratic function f(x) = (x + 1)² + 8, we can find the values of f(2) and f(6) by substituting x = 2 and x = 6 into the function:

f(2) = (2 + 1)² + 8 = 12

f(6) = (6 + 1)² + 8 = 50

Therefore, the rate of change for f(x) over the interval 2 ≤ x ≤ 6 is:

slope = (f(6) - f(2)) / (6 - 2) = (50 - 12) / 4 = 9.5

So the answer is: The rate of change for f(x) is 9.5 over the interval.

To find the rate of change for the linear function g(x) = -2x - 6, we can use the same formula:

g(2) = -2(2) - 6 = -10

g(6) = -2(6) - 6 = -18

Therefore, the rate of change for g(x) over the interval 2 ≤ x ≤ 6 is:

slope = (g(6) - g(2)) / (6 - 2) = (-18 - (-10)) / 4

slope = -2

So the answer is: The rate of change for g(x) is -2 over the interval.

Answer:  option C - Sandy's experimental probability was closest to the theoretical probability in the experiment with 1,000 flips, is the most likely scenario.

Step-by-step explanation:

Based on the Law of Huge Numbers, the more times a coin is flipped, the closer the test likelihood will be to the hypothetical likelihood of 0.5 for heads and 0.5 for tails. In this manner, Sandy's exploratory likelihood is most likely to be closest to the hypothetical likelihood within the test with 1,000 flips.

In spite of the fact that it is conceivable that Sandy's exploratory likelihood might be near to the hypothetical likelihood within the explore with 100 flips or 500 flips, it is more likely that the bigger test measure of 1,000 flips will result in a more precise representation of the hypothetical likelihood.

Tangent ratios can be greater than or equal to 1 because acute angle is between 45 degrees and 90 degrees.

If the opposite side is longer than the adjacent side, then the tangent ratio will be greater than 1.

Similarly, if the opposite side is equal in length to the adjacent side, then the tangent ratio will be equal to 1.

In general, the tangent ratio can be greater than or equal to 1 when the opposite side is longer or equal in length to the adjacent side. This occurs when the acute angle is between 45 degrees and 90 degrees.

It is important to note that when the acute angle is less than 45 degrees, the tangent ratio will always be less than 1. Conversely, when the acute angle is greater than 90 degrees, the tangent ratio will be negative and less than 1.

It is an exercise of linear equations with one variable is a fundamental topic in the study of algebra. These types of equations are characterized by being first-degree polynomials in one variable, and can be found in various contexts, such as physics, economics, engineering, among others. Therefore, the ability to solve these equations is essential in the training of any mathematics student and in the development of their ability to solve problems in real life situations.

A linear equation with a variable can be solved by means of a series of algebraic operations that allow us to simplify the expression and clear the variable to be solved. These operations include adding, subtracting, multiplying, and dividing, always maintaining equality between both sides of the equation. The ultimate goal is to find the numerical value that satisfies the equation, that is, the value that makes the equality true.

Solving linear equations with one variable is an important skill not only for mathematics students, but also for professionals in various fields. For example, in engineering, linear equations are used to model physical systems and phenomena, and their resolution is necessary to perform calculations and make informed decisions. In the economy, they are used to analyze the behavior of financial variables and make projections for the future.

To solve the equation 11x - 24 = 7x + 76 we need to isolate the variable x on one side of the equation.

First, we can simplify both sides of the equation by combining like terms:

      11x - 7x = 76 + 24

Which gives us

       4x = 100

Next, we can solve for x by dividing both sides of the equation by 4:

       4x/4 = 100/4

       x = 25

Therefore, the solution to the equation is x = 25.

To determine whether the normal approximation can be used to study the proportion of students in the population who go home every weekend, we need to check if the sample size is large enough and if the success-failure condition is met.

Sample size: A commonly used rule of thumb is that the sample size should be at least 10 times the number of successes and failures combined. In this case, the number of students who go home every weekend in the sample is 18, and the number who do not is 82. So the sample size is 100, which is greater than 10 times the number of successes and failures combined.

Success-failure condition: Another assumption for the normal approximation is that the sample proportion is not too close to 0 or 1. In this case, the sample proportion of students who go home every weekend is 18/100 = 0.18, and the proportion who do not is 0.82. Both proportions are between 0.1 and 0.9, so the success-failure condition is met.

Therefore, we can use the normal approximation to study the proportion of students in the population who go home every weekend.
