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

Thus,required solution of the quadratic function are 2 or -2.

Answer:  D. percentages only for each line item.

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.

The runner's average speed in kilometers per hour is 24.257 km.

The total distance covered by the runner is 1 mile. The relation between kilometers and miles is given as 1 km = 0.62 mi. Converting 1 mile to km by using the given relation, we get-

Distance = 1 mile

 = 1 mile × [1 km/0.62 mile]

= 1.6129 km

The time taken to complete a 1-mile run is 3 minutes and 59.37 seconds. The relation between hours and minutes is given below.

1 hour = 60 minutes ……(1)

Converting 3 minutes to hours using equation (1), we get-

3 minutes = 3 minutes × [1 hour/60 minutes]

= 0.05 hours

The relation between hours and seconds is given below.

1 hour = 3600 second …….(2)

Converting 59.37 seconds to hours using equation (2), we get-

59.37 seconds = 59.37 seconds × [1 hour/3600 seconds]

= 0.016492 hours

Total time to cover 1 mile = (0.05 + 0.016491) hours = 0.066492 hours

The average speed of the runner is calculated by the following relation-

Average Speed = Distance (km)/time (hours)

= 1.6129 km/0.066492 hours

= 24.257 km/hour

Therefore, the average speed in kilometers per hour is 24.257km.

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.

Answer: This is a geometric sequence, because each term is obtained by multiplying the previous term by a constant ratio. In this case, the ratio is -2.

To find the 9th term, we can use the formula for the nth term of a geometric sequence:

a_n = a_1 * r^(n-1)

where:

a_n is the nth term of the sequence

a_1 is the first term of the sequence (9)

r is the common ratio (-2)

n is the term number (9)

Plugging in the values:

a_9 = 9 * (-2)^(9-1) = 9 * (-2)^8 = 9 * -256 = -2304

So the 9th term of the sequence is -2304

There are several different sampling methods that could be employed for this study, including:

Simple random sampling: This method involves randomly selecting a certain number of students from each campus and measuring the distance between their hometowns and their campuses.

Stratified random sampling: This method involves dividing the student population at each campus into different strata (e.g. by major or year in school) and then randomly selecting a certain number of students from each stratum.

Cluster sampling: This method involves randomly selecting a certain number of campuses and then measuring the distance between the hometowns of all students at those campuses and their respective campuses.

Multi-stage sampling: This method involves using a combination of the above methods, such as first using cluster sampling to select a certain number of campuses and then using stratified random sampling to select a certain number of students from each campus.

This study would be an enumerative study because it seeks to measure the characteristics of a population, in this case, the average distance between the hometowns of students and their campuses, by counting and measuring them.

The probability of spinning an odd number first then spinning an even number is 3/8 x 4/8 = 12/64.

This can be expressed as a fraction, decimal, or percentage. As a fraction, this probability is 12/64. As a decimal, this probability is 0.1875. As a percentage, this probability is 18.75%.

To calculate this probability, we first need to calculate the probability of spinning an odd number first. Since there are eight sections and four of them are odd numbers (1, 3, 5, 7), the probability of spinning an odd number is 4/8. We then need to calculate the probability of spinning an even number. Since there are four even numbers (2, 4, 6, 8), the probability of spinning an even number is 4/8. Finally, we multiply these two probabilities together to get the probability of spinning an odd number first then spinning an even number, which is 3/8 x 4/8 = 12/64.

The comparable word in Bryan's pattern is 28 whereas the number in Liam's pattern is 49.

The difference between every two successive terms in an arithmetic series is always the same. The number "a" is the first term, and "d" is the common difference between the. sequence. The nth term of an arithmetic sequence is given by. aₙ = a + (n – 1)d

Given this, we must first determine what is the position of 49 in Liam's pattern. Since Liam's pattern starts at 7 and increases by 7 each time, we can say that

d = 7

a₁ = 7

Substituting these values, we will get

49 = 7 + (n - 1) * 7

49 = 7 + 7n - 7

49 = 7n

n = 7

we are asked what is the corresponding term in Bryan's pattern when the number in Liam's pattern is 49. Since 49 is the 7th term in Liam's pattern, we need to find the 7th term in Bryan's pattern. As stated in the problem, Bryan's pattern starts at 4 and increases by 4 each time. This means that

d = 4

a₁ = 4 n = 7

Substituting these values, we will get

a₇= 4 + (7 - 1) * 4

a₇ = 4 + (6) * 4

a₇ = 4 + 24

a₇ = 28

Therefore, when the number in Liam's pattern is 49, the corresponding term in Bryan's pattern is 28.

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%.
