We can write the coordinates after reflection as -

A (x₁, y₁) → A" (x₁, - y₁)

B (x₂, y₂) → B" (x₂, - y₂)

C (x₃, y₃) → C" (x₃, - y₃)

Given is that to describe a sequence of transformation that maps triangle ΔABC onto triangle ΔA”B”C” a student starts with a reflection over x - axis.

Assume the coordinates of a triangle are -

A (x₁, y₁)

B (x₂, y₂)

C (x₃, y₃)

So after the reflection over the {x} axis, we can write the coordinates as -

A" (x₁, - y₁)

B" (x₂, - y₂)

C" (x₃, - y₃)

Therefore, we can write the coordinates after reflection as -

A (x₁, y₁) → A" (x₁, - y₁)

B (x₂, y₂) → B" (x₂, - y₂)

C (x₃, y₃) → C" (x₃, - y₃)

For the given case the Null hypothesis is The mean mpg of the 91 cars tested is equal to the manufacturer's mpg rating of 55.7 and the  Alternative hypothesis is The mean mpg of the 91 cars tested is less than the manufacturer's mpg rating of 55.7.

In order to determine whether the cars underperform the manufacturer's mpg rating, the independent testing firm would need to perform a hypothesis test. To do this, they would need to compare their sample mean of 55.2 mpg with the manufacturer's mpg rating of 55.7. They would also need to know the standard deviation of the sample, which is 3.24.

The independent testing firm would then calculate the z-score by subtracting the manufacturer's rating from the sample mean, and dividing it by the standard deviation. If the z-score is greater than the critical value for a 0.05 level of significance, then there is sufficient evidence to reject the null hypothesis.

In this case, the z-score is -1.51. Since the critical value for a 0.05 level of significance is 1.96, the z-score is less than the critical value. Therefore, there is not sufficient evidence to reject the null hypothesis, and we cannot conclude that the cars underperform the manufacturer's mpg rating.

Exercise can be beneficial for academic performance in a variety of ways.

Improved cardiovascular health, for example, can lead to improved blood flow to the brain, providing a better environment for learning and memory formation. Exercise can also improve mental health, reduce stress, and increase energy levels, helping to better prepare for tests and exams. Finally, exercise can help to improve concentration, focus, and overall cognitive function.

The formula for calculating the potential benefits of exercise on academic performance is:

Academic Performance = Exercise + Improved Cardiovascular Health + Mental Health + Stress Reduction + Energy + Concentration + Focus + Cognitive Function

By increasing the amount of exercise, the individual can increase their academic performance. This is done by improving cardiovascular health, mental health, stress levels, energy, concentration, focus, and cognitive function. All of these factors play a role in academic performance, and increasing any one of them can lead to an overall improvement in academic performance.

The required solution of the given quadratic equation are 2 or -2.

A quadratic equation is a second-order polynomial equation in a single variable x ax² +bx+c=0. with a ≠ 0 . Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution.

We have,

b² -4=0

Here we will use identity a² - b² = (a+b)(a-b)

Then,

b² -4=0

b² - (2)² = 0

(b + 2)(b - 2) = 0

b + 2 = 0

b = -2

Or b - 2 = 0

b = 2

Horizontal analysis, also known as trend analysis, is a method of financial statement analysis that compares line items over time by expressing them as a percentage of a base year. The base year is typically the most recent year, and the comparison is typically made to the prior year. In horizontal analysis, the increases and decreases are shown as percentages for each line item, so that the changes in the line items can be easily compared and analyzed. This is different from vertical analysis, which shows the line items as a percentage of a total, such as total assets or total revenue.

Step-by-step explanation:  

Check the picture below.

According to the given information in the question rounded to the nearest hundredth, the probability is 0.14.

Probability is a measure of how likely something is to occur. The probability is computed by dividing the total possible outcomes by the number of possible ways the event could occur.

Adding the probabilities together will yield the chance of a simple event occurring. Your total chances of acquiring something are 10% + 25% = 35%, for instance, if you have an 10% opportunity to win $10 and a 25 percentage chance of getting $20.

The probability of a student studied for exactly 5 hours can be calculated using the formula for probability of a discrete event:

P(X = 5) = (number of ways to get a 5) / (total number of outcomes)

From the data provided, we know that 5 students studied for 5 hours. And there were a total of 35 students surveyed. So the probability is:

P(X = 5) = 5/35 = 0.14

Rounded to the nearest hundredth, the probability is 0.14.

Step-by-step explanation:

The probability that the mean number of raisins in the Happy Trail Mix is more than the mean number of raisins in the generic mix is 9.7%.

To solve this problem, we need to use the central limit theorem, which states that the distribution of the sample means approaches a normal distribution as the sample size increases. With a sample size of 17, we can approximate the distribution of the sample means as normal.

Let's call the mean of the Happy Trail Mix sample x and the mean of the generic mix sample y.

Using the formula for the mean of a normal distribution, we can find the mean of x and y:

μx = μ = 33.6

μy = μ = 28.8

Using the formula for the standard deviation of the sample mean, we can find the standard deviation of x and y:

σx = σ/√n = 8.4/√17 = 2.04

σy = σ/√n = 12.7/√17 = 3.08

Now that we have the mean and standard deviation of x and y, we can use a normal distribution calculator or a z-score table to find the probability that x > y.

The z-score is given by:

z = (x - y - μ)/σ = (33.6 - 28.8)/(√(2.04^2 + 3.08^2)) = 1.30

Using a standard normal table, we find that the probability of a z-score being greater than 1.30 is 0.097, or 9.7%.

All of the statements that are true include the following:

II. The hypothesis was supported with the results of the experiment.

III. It can be concluded that every time 8 wraps are added to the nail, the total number of paper clips lifted doubles.

Therefore, the correct answer option is: A. II and III only.

In Science, a hypothesis is primarily considered to be a tentative or an educated guess and it can be defined as a testable explanation for an observation, result, or a specific experimentation (scientific) problem, especially through the use of the "if . . . then . . . because" format.

Based on the information provided about this experiment, we can reasonably infer and logically deduce that the hypothesis developed about the steel nail is true because when eight (8) wraps of an insulated copper wire are added to the steel nail, the total number of paper clips that would be lifted is twice as many paper clips.
