An experiment is a process of obtaining data by testing a hypothesis while controlling for variables that may affect the results. A control group is used to establish a baseline level of the dependent variable and compare it to the experimental group’s results. Here, the answer to the given question is that the control group is the group of participants who are exposed to all experimental conditions, except the independent variable or treatment variable. In an experiment, there are two types of variables, the independent variable and the dependent variable. The independent variable is the variable that the experimenter manipulates, whereas the dependent variable is the variable that is affected by the independent variable.
The control group in an experiment is a group of participants who are exposed to all experimental conditions except for the independent variable or treatment variable. The control group is used to compare the experimental group’s results, establishing a baseline level of the dependent variable.

In an experiment, the independent variable is manipulated to see how it affects the dependent variable. The control group is essential in an experiment because it provides a comparison to the experimental group's results. The independent variable is the variable that is being tested and manipulated by the experimenter. It is also the variable that the experimenter believes has an effect on the dependent variable. The dependent variable is the variable that changes in response to the independent variable. It is also the variable that the experimenter measures to see if the independent variable had an effect. In summary, the control group is the group of participants who are exposed to all experimental conditions, except the independent variable or treatment variable.

The statement, When two events are disjoint, they are also independent is false.

In a sample space, we can use probability laws to determine the probabilities of these events and how they relate to each other. Disjoint Events: Two events are non-overlapping or mutually exclusive if they have no common outcome. Mathematically, this can be written as, P(B ∩ A) = 0 --(1)

Independent Events: Events are independent when they do not "affect" the probability of another event occurring. Mathematically written as:

P(B/A) = P(B) P(A and B)

=> P(B ∩ A) = P(B) × P(A) --(2)

(1) ) and (2) events cannot be independent unless they overlap. That is, if events do not overlap, they are also dependent. Hence, disjoint events are not independent that means the above statement is false.

Step-by-step explanation:

Differentiating the formula for the area of a triangle gives the relationship between the various rates of change.

  A = 1/2bh

  A' = 1/2(b'h +bh') . . . . . relation of rates of change

__

When the area is 83 cm², and the height is 9 cm, the base length is ...

  83 cm² = 1/2b(9 cm)

  b = 166/9 cm

Filling in the given values and rates of change, we have ...

  3.5 cm²/min = 1/2(b'·(9 cm) +(166/9 cm)(2.5 cm/min))

  7 cm²/min -46 1/9 cm²/min = (b')(9 cm)

  b' = (-39 1/9 cm²/min)/(9 cm) = -4 28/81 cm/min

The base of the triangle is changing at the rate of -4 28/81 cm/min, about -4.346 cm/min.

The conditions for conducting one-sample t-procedures are as follows:

1. Random Sample: The data should be obtained from a random sample or a randomized experiment to ensure that it is representative of the population of interest. This condition helps to minimize bias and ensure the validity of statistical inference.

2. Independence: The observations within the sample should be independent of each other. In other words, the values should not be influenced by each other and should be selected or measured independently. Violation of independence can lead to inaccurate results.

3. Normality or Large Sample Size (Central Limit Theorem): The population from which the sample is drawn should follow a normal distribution, or the sample size should be sufficiently large. If the population is known to be normally distributed, there are no specific requirements on the sample size. However, if the population distribution is unknown, the sample size should generally be at least 30 to apply the Central Limit Theorem, which states that the sample mean tends to follow a normal distribution, regardless of the population distribution shape.

4. Outliers: The presence of outliers can have a significant impact on the results of t-procedures. It is important to check for and address any outliers in the data. Outliers can distort the distribution and violate the assumptions of the t-test.

5. Equal Variances (for two-sample t-test): In the case of a two-sample t-test, if comparing two groups, the variances of the two populations should be equal. This assumption is necessary for calculating the correct degrees of freedom and obtaining accurate results. If the variances are not equal, a modified version of the t-test, called the Welch's t-test, can be used instead.

It is important to carefully assess these conditions before conducting one-sample t-procedures to ensure that the results are valid and reliable. Violations of these conditions may require alternative statistical tests or adjustments to the analysis.

Answer:

$29

Step-by-step explanation:

A PS5 costs $500. Subtract 500 from the total cost:

645 - 500 = 145

There are 5 games in total, costing $145 in all. Assuming all of them have the same price, simply divide 145 with 5:

145/5 = 29

Each game costs $29.

~

Answer:

$29

Step-by-step explanation:

If the total cost is 645, then we must subtract the cost of the PS5 to get the cost of the games. This then gets us 145. Next, we have to divide 145 by 5 to see the cost of each game. By doing these steps, you should get $29 for each game.

The general form of a quadratic equation is Ax^2 + Bx + C.

For the given expression 2 + 6x^2 - 2x, it is already in general form with A = 6, B = -2, and C = 2.

So the general form of this expression is 6x^2 - 2x + 2.

Quadratic equations are the polynomial equations of degree 2 in one variable of type f(x) = ax2 + bx + c = 0 where a, b, c, ∈ R and a ≠ 0. It is the general form of a quadratic equation where ‘a’ is called the leading coefficient and ‘c’ is called the absolute term of f (x). The values of x satisfying the quadratic equation are the roots of the quadratic equation (α, β).

The solution or roots of a quadratic equation are given by the quadratic formula:

(α, β) = [-b ± √(b2 – 4ac)]/2a

Sum and product of roots: If α and β are the roots of a quadratic equation, then

S = α+β= -b/a = -coefficient of x/coefficient of x^2

P = αβ = c/a = constant term/coefficient of x^2

The formula of integration by parts is ∫ u dv = uv - ∫ v du

The integration by parts formula is a technique used to integrate the product of two functions. It is often written in the following form:

∫ u dv = uv - ∫ v du

where u and v are functions of x and dv and du are their differentials.

To use this formula, one selects u and dv such that the integral on the right-hand side is easier to evaluate than the original integral on the left-hand side. The goal is to eventually reduce the integral to a form that can be evaluated using basic integration rules.

To integrate a given function f(x) using the integration by parts formula, one typically follows these steps:

1) Choose u and dv. Typically, u is chosen as a part of the integrand that will simplify when differentiated, and dv is chosen as the remaining part.

2) Compute du and v. Differentiate u to obtain du, and integrate dv to obtain v.

3) Plug u, du, v, and dv into the integration by parts formula.

4) Simplify the resulting expression by combining like terms and evaluating any remaining integrals.

5) If necessary, repeat the process with the remaining integral until a solution is obtained.

The navy sector would be represented by a sector with a degree measure of approximately 97.2 degrees.

To find the degree measure for the sector for the navy in a circle graph, you need to calculate the percentage of the total number of personnel represented by the navy. To do this, you would add up the number of personnel in all branches of service, which is 500. Then, you would divide the number of navy personnel, which is 135, by 500 and multiply the result by 360 degrees (the total number of degrees in a circle).

So, the degree measure for the sector for the navy in a circle graph would be:

(135/500) x 360 = 97.2 degrees.

Therefore, the navy sector would be represented by a sector with a degree measure of approximately 97.2 degrees.

The solution to the given initial value problem is:

y1(t) = 3t - 2sin(2t) + 11/10sinh(t) - 11/10sinh(2t)

y2(t) = 6t + 7/10cosh(t) - 17/10sinh(t)

Taking the Laplace transform of the given system of differential equations, we get:

sY1(s) - y1(0) = 5Y1(s) - 4Y2(s) - 2(2/(s^3)) + 2(1/(s^2))

sY2(s) - y2(0) = 10Y1(s) - 77(1/s) - 17(1/(s^2)) - 2(1/(s^2))

Applying the initial conditions, we get:

sY1(s) - 3 = 5Y1(s) - 4Y2(s) - 4/s^3 + 2/s^2

sY2(s) = 10Y1(s) - 77/s - 17/s^2 - 2/s^2

Solving for Y2(s), we get:

Y2(s) = (10Y1(s) - 77/s - 17/s^2 - 2/s^2)/s

Substituting this in the equation for Y1(s), we get:

sY1(s) - 3 = 5Y1(s) - 4[(10Y1(s) - 77/s - 17/s^2 - 2/s^2)/s] - 4/s^3 + 2/s^2

Simplifying and solving for Y1(s), we get:

Y1(s) = (3s^3 + 10s^2 + 8s + 154)/(s^5 + 5s^3 + 4s)

Taking the inverse Laplace transform, we get:

y1(t) = 3t - 2sin(2t) + 11/10sinh(t) - 11/10sinh(2t)

y2(t) = 6t + 7/10cosh(t) - 17/10sinh(t)

Therefore, the solution to the given initial value problem is:

y1(t) = 3t - 2sin(2t) + 11/10sinh(t) - 11/10sinh(2t)
