Given that, A college has 5,000 students. Of those 5,000 students, 3,900 are science majors.

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

Percentage can be calculated by dividing the value by the total value, and then multiplying the result by 100. The formula used to calculate percentage is: (value/total value)×100%.

Now, percentage of science majors = Science majors / Total number of students × 100

= 3900/5000 × 100

= 0.78 × 100

= 78%

Therefore, the percentage of the student body are science majors is 78%.

Answer:

y = -x - 8

Step-by-step explanation:

Use the slope intercept  equation of a line.

Substitute the slope(m) and the point into the equation and solve for "b", (which is the y-intercept).

y = mx +b

-10 = -1(2) + b

-10 = -2 +  b          Solve for "b"

-10 + 2 = b

  -8 = b

Now, write the equation using the value of the slope and the value of b.

 y = -1x - 8  or y = -x - 8

The maximum Number of  scholars in each row is 12. This means that the  scholars can be arranged in rows with an equal number of  scholars, and each row can have a  outside of 12  scholars.

To find the maximum number of  scholars in each row, we need to determine the  topmost common divisor( GCD) of the total number of  scholars in each section. The GCD represents the largest number that divides all the given  figures unevenly.  

Given that there are 24, 36, and 60  scholars in the three sections, we can calculate the GCD as follows    Step 1 List the  high factors of each number  24 =  23 * 31  36 =  22 * 32  60 =  22 * 31 * 51    

Step 2 Identify the common  high factors among the three  figures  Common  high factors 22 * 31    Step 3 Multiply the common  high factors to find the GCD  GCD =  22 * 31 =  4 * 3 =  12  

 thus, the maximum number of  scholars in each row is 12. This means that the  scholars can be arranged in rows with an equal number of  scholars, and each row can have a  outside of 12  scholars.

The Chi-square test is a statistical test used to determine if there is a significant difference between observed and expected frequencies in categorical data. In this example, the test is used to assess whether there is a significant difference in the mean breaking strengths of two types of cables.

The Chi-square test of significance is employed when dealing with categorical or nominal data. It compares the observed frequencies with the frequencies that would be expected if the variables were independent. In this case, the breaking strengths of the two cables are the variables of interest.

To perform the test, the first step is to define the null hypothesis (H0) and the alternative hypothesis (Ha). In this example, H0 assumes that there is no difference in the mean breaking strengths of the two cables, while Ha suggests that there is a difference.

Next, the test statistic, denoted by X2 (chi-square), is calculated using the formula X2 = Σ[(O - E)²/E], where O represents the observed frequencies and E represents the expected frequencies under the assumption of independence.

To determine the expected frequencies, we need to estimate the means and variances of the breaking strengths. Here, x = 1925 and sigma = 40 for the first cable, and x = 1905 and sigma = 30 for the second cable.

Once the test statistic is calculated, it is compared to a critical value from the Chi-square distribution with degrees of freedom equal to (r - 1)(c - 1), where r is the number of rows and c is the number of columns in the contingency table. The significance level of 0.01 determines the critical value.

If the calculated X2 value is greater than the critical value, we reject the null hypothesis and conclude that there is sufficient evidence to indicate a difference in the mean breaking strengths of the two cables. Conversely, if the calculated X2 value is less than or equal to the critical value, we fail to reject the null hypothesis and conclude that there is no significant difference.

The equation of the circles graphed below are (x - 2)²+ (y - 3)² = 16 and x² - 4x + y² - 6y + 9 = 0

The circle appears to be centered at points (2,3) and has a radius of 4 units. Therefore, the equation of the circle can be written in the standard form:

(x - 2)²+ (y - 3)² = 16

Alternatively, we can expand the equation and write it in the general form:

x² - 4x + y² - 6y + 9 = 0

Both of these equations represent the same circle with center (2,3) and radius 4.

The point estimate that can be used to estimate the true mean population is 11.97 inches.

To find the point estimate that can be used to estimate the true population mean, we need to take the sample mean of the given observations. The formula for the sample mean is:

Mod(X)= (Σx) / n

where Mod(X)  is the sample mean, Σx is the sum of all the observations, and n is the size.

Using the given observations, we can calculate the sample mean as follows:

Mod(X) = (11.3 + 10.7 + 12.4 + 15.2 + 10.1 + 12.1 + 16.2 + 10.5 + 11.4 + 11.0 + 10.7 + 12.0) / 12

Mod(X) = 11.97

Answer:

D

Step-by-step explanation:

First, yes, it is a function. Functions are defined as having one output per input, and given a number on this graph, we can find only one output.

Domain is the range of x-values in a graph. The domain here is from \(-\pi\) to \(\pi\).

Range is the range of y-values in a graph. The range here is from -1 to 1.

This graph has three intercepts at \((-\pi ,0)(0,0)(\pi ,0)\).

Symmetry: This graph has rotational symmetry, meaning it can be rotated about a point to map onto itself. Here, we can rotate it 180 degrees about the origin to map onto itself.

The length of the pendulum is approximately 24.99 cm.

The formula for the period of a pendulum is:

T = 2π√(L/g)

where T is the period in seconds, L is the length of the pendulum in meters, and g is the acceleration due to gravity (approximately 9.81 \(m/s^2\)).

To find the length L of the pendulum in centimeters, we can rearrange the formula as follows:

L = (T/2π\()^2\) * g

Substituting T = 0.537 s and g = 9.81 m/s^2 (which is equivalent to 981 cm/s^2), we get:

L = (0.537/(2π)\()^2\) * 981

L ≈ 24.99 cm

Therefore, the length of the pendulum is approximately 24.99 cm.

We have to find the equation of the streamline passing through the point (1, 3) which is given as (x, y) = (1, 3) and the fluid velocity vector `v` is given by `v = 2yi + 10xj`.Now, vx = 10x and vy = 2yds/vx = dy/vyds = |v|/vx dxds = (10x) dx / (2y)ds = 5x/y dxdy = (2y) ds / (10x)dy = x/5y dxdy = 2yds / 10xdy/dx = 2y/10x = y/5xIntegrating the above equation, we get:y2/2 = (1/5) x2 + c, where c is constant.

Answer:

The remainder is 4.

Step-by-step explanation:

Note: This question is not correctly stated. It is therefore correctly restated before answering the question as follows:

When 17 is divided by k; where k is a positive integer less than 17, the remainder is 3. What is the remainder when the sum of the possible values of k is divided by 17?

The explanation of the answer is now given as follows:

Since k < 17, it implies that the possible values of k must be from between 1 and 16 inclusive.

Between 1 and 16, only 7 or 14 will give a remainder of 3 when either of them is used to divide 17. Therefore, 7 and 14 are the possible values of k.

Therefore, we have:

Sum of the possible values of k = 7 + 14 = 21

Also, we have:

Sum of the possible values of k divided by 17 = 21 / 17 = 1 with a remainder of 4.

Therefore, the remainder is 4 when the sum of the possible values of k is divided by 17.

The solution for system of equation provided as per the given question will be x = -19 and y = 55 or (-19,55).

It is given that the equations are:

Simplifying it further, we get:

y + 3x = -2 (equation 1)

5x + 2y = 15 (equation 2)

Multiplying y + 3x = -2 by 2 and subtracting from 5x + 2y = 15, we get:

2y - 2y + 5x -6x = 15 + 4

-x = 19

You would expect to find a negative correlation between rainfall and sales of sunscreen, as more rain typically means fewer people buying sunscreen.

Rainfall and sales of sunscreen would have a negative correlation, as more rain typically means fewer people buying sunscreen. This is because when it rains, typically people do not go out in the sun, so they do not need to purchase sunscreen. Additionally, when it rains, the UV rays are blocked, so people do not feel the need to buy sunscreen to protect their skin. Therefore, when it rains, the sales of sunscreen typically decrease. On the other hand, when it is sunny, people are more likely to go outside and purchase sunscreen to protect their skin from the sun’s harmful UV rays. Therefore, the more rain there is, the lower the sales of sunscreen will be and vice versa.
