In the class, there are 3000 students per the concept of solving an equation.

According to the given information, the average of the marks on the exam in the class was initially 80%.

If 15 of the students had each gotten a mark that was 10 points higher, the average would have been 85%.

To solve for the number of students in the class, set up an equation based on the average formula:

((80% × n) + (10 × 15) / n = 85%

Let's simplify this equation and solve for "n":

(0.8n + 150) / n = 0.85

Multiply both sides of the equation by "n" to eliminate the denominator:

0.8n + 150 = 0.85n

150 = 0.05n

n = 150 / 0.05

n = 3000

Therefore, there are 3000 students in the class.

Step-by-step explanation:

Swath width = 276.5 km, pixel resolution on ground = 29.4 cm, number of pixels across swath = 940, maximum integration time per pixel = 4.11 ms.

We first determine the telescope's field of view using the lens diameter and focal length, then multiply it by the altitude. The pixel resolution on the ground is calculated by dividing the pixel size by the altitude and multiplying by 206265, which converts the result to meters. Finally, the number of pixels across the swath is determined by dividing the swath width by the pixel resolution.

It is by dividing the pixel resolution by the ground speed of the telescope. The ground speed is determined using the orbit altitude and period, and the dwell time per pixel is expressed in milliseconds. The maximum integration time per pixel represents the amount of time the detector can collect light while the telescope moves across one pixel on the ground.

The number of groups of five courses the student can select for the next semester is 126.

In order to answer this question, we must first determine how many courses the student has already taken. If the student has already taken 11 courses, then the total number of courses she needs to take is 9.

We can use the formula for combinations, nCr, to calculate the number of groups of five courses that she can select for the next semester. The formula is nCr=n!/(r!(n-r)!). In this case, n is the total number of courses (9) and r is the number of courses in each group (5).

Therefore, the number of groups of five courses the student can select for the next semester is 9C5, or 9!/[5!(9-5)!], which equals 126. This means the student can select 126 different groups of five courses for the next semester.

We obtain the 99% confidence interval for the proportion of GSU juniors who believe they will find a job immediately after graduation.

To calculate the 99% confidence interval for the proportion of GSU juniors who believe they will find a job immediately after graduation, we can use the formula: Confidence Interval = Sample Proportion ± (Critical Value * Standard Error)

First, we calculate the sample proportion, which is the number of students who believe they will find a job (2915) divided by the total sample size (3926).

Sample Proportion = 2915 / 3926 ≈ 0.7428

Next, we need to determine the critical value corresponding to a 99% confidence level. Using a standard normal distribution, the critical value is approximately 2.576.

The standard error can be calculated using the formula: Standard Error = sqrt((Sample Proportion * (1 - Sample Proportion)) / Sample Size)

Plugging in the values, we get: Standard Error ≈ sqrt((0.7428 * (1 - 0.7428)) / 3926)

Finally, we can calculate the confidence interval: Confidence Interval = 0.7428 ± (2.576 * Standard Error)

By substituting the values, we obtain the 99% confidence interval for the proportion of GSU juniors who believe they will find a job immediately after graduation.

According to Siegler, the pattern of learning math concepts involves a gradual development and refinement of strategies. Siegler's theory, known as the overlapping waves model, suggests that learners use multiple strategies simultaneously and gradually shift towards more efficient ones over time. This process allows for a better understanding and application of math concepts, ultimately leading to improved problem-solving skills.

According to Siegler, the pattern of learning math concepts involves a gradual progression from using counting strategies to more efficient and accurate strategies. Children initially rely on counting strategies to solve math problems, such as counting fingers or objects. As they progress, they begin to use more advanced strategies, such as decomposition or mental math, which allow them to solve problems more quickly and accurately. Siegler also emphasizes the importance of practice and repetition in developing math skills and the role of feedback and instruction in promoting learning. Overall, Siegler's theory suggests that children's math skills develop through a combination of innate abilities and environmental factors, including exposure to math concepts and opportunities for practice and instruction in time.

The number of values in each group of the data set would be equal to the degrees of freedom for each group plus one.

In order to determine the number of values in each group of the data set based on the partially completed ANOVA table, we need to consider the total number of observations and the number of groups.

The ANOVA table consists of three main components: "Source of Variation," "Sum of Squares (SS)," and "Degrees of Freedom (df)." The "Source of Variation" represents the different factors or groups in the data set, while the "Sum of Squares" measures the variability within each group. The "Degrees of Freedom" represents the number of independent pieces of information available for estimating the population parameters.

In this case, since all groups are of the same size, we can determine the number of values in each group by examining the "Degrees of Freedom" column. The degrees of freedom for each group is the group size minus one (df = group size - 1). By adding one to the degrees of freedom for each group, we obtain the number of values in each group.

What is the volume of a cylinder?

A cylinder's volume refers to the amount of interior room it has to hold a given quantity of material.

Formula to calculate the volume of a cylinder

volume = π r² h

where r is the radius of the cylinder and h is the height.

Here, we have

radius = 6m

dV/dt = 3

We have to find:  dh/dt

volume = π r² h

Differentiating both sides with respect to t, we get

dV/dt = π[2r(dr/dt)h + r²(dh/dt)]

r remains constant (r = 6), dr/dt = 0

So, dV/dt = πr²(dh/dt)

Substituting the values, we get

2 = π(6)²(dh/dt)

dh/dt = 2/(36π)

= 0.017m/min

Hence, 0.017 m/min is the height of increasing water.

The relationship between the ratios of sin x° and cos yº is that they are reciprocals. The correct answer is option c. The ratios of sin x° and cos yº are reciprocals of each other.

In trigonometry, sin x° represents the ratio of the length of the side opposite the angle x° to the length of the hypotenuse in a right triangle. Similarly, cos yº represents the ratio of the length of the adjacent side to the length of the hypotenuse in a right triangle.

Since the hypotenuse is the same in both cases, the ratios sin x° and cos yº are related as reciprocals. This means that if sin x° is equal to 12/13, then cos yº will be equal to 13/12. The reciprocals of the ratios have an inverse relationship, where the numerator of one ratio becomes the denominator of the other and vice versa.

It's important to note that the signs of the ratios can vary depending on the quadrant in which the angles x° and yº are located. However, the reciprocal relationship remains the same regardless of the signs.

Answer: GCD(24,42) = 42

48 is one possibility for the third number.

Step-by-step explanation:

Given two numbers out of 3 are 24 and 42.

Prime factorization of 24 and 42 is

24 = 2 x 2 x 2 x 3

42= 2 x 3 x 7

We can see the greatest common division (GCD) of 24 and 42 = 2 x 3 = 6

Now if third number is greater than 42 and does not change the GCF, the we take nearest possible number as 42 + GCD(24,42) = 42+6 = 48

Such that GCD (24,42,48)=6

So, 48 is one possibility for the third number.
