Answer:

37

Step-by-step explanation:

f(4) just means use 4 for x. The table has all the x's across the top (sometimes they are in columns instead) The f(x) in the second row is the output that goes with each x. When x is 4, the f(x) is 37.

All is one math sentence:

f(4) = 37

Option C. An ANOVA examines whether mean differences exist between conditions, whereas a t-test does not is the correct comparison between an ANOVA and a t-test.

What is ANOVA?

ANOVA (Analysis of Variance) is a statistical method that helps to compare three or more means or groups. It is used in behavioral and social sciences research, which determines whether the mean of the dependent variable is significantly different across different levels of an independent variable.

It is used for statistical inference in comparing the means of two or more groups. ANOVA is based on the idea of variance; that is, the variation between the groups' means is compared to the variation within the groups. By assessing the significance of the difference between group means, ANOVA determines whether there is sufficient evidence to conclude that they are not all equal.

What is a t-test?

A t-test is a statistical hypothesis test that compares the means of two independent groups. It is used when the data in each of the groups being compared is normally distributed. The t-test is a parametric test that compares the means of two groups and calculates the standard error of the difference between the means. It compares the difference between the two groups to the variability within each of the groups. The difference between the sample means is examined relative to the variability between the groups. The t-test produces a test statistic that can be compared to a critical value to determine if the means of the two groups differ significantly. It is commonly used to examine if the means of two independent groups are significantly different.

The primary differences between t-test and ANOVA are in terms of the number of groups, and that ANOVA is used for testing the significance of differences between more than two groups while t-tests are used for testing differences between two groups. Hence, ANOVA is used when we want to compare three or more groups, while t-tests are used when we want to compare two groups. Option C. An ANOVA examines whether mean differences exist between conditions, whereas a t-test does not is the correct comparison between an ANOVA and a t-test.

Answer:

5.5 = AB

Step-by-step explanation:

take 62 degree as reference angle

using cos rule

cos 62 = adjacent / hypotenuse

0.46 = AB / 12

0.46*12 = AB

5.52 = AB

5.5 = AB

The length of side AB in the given right angle triangle of hypotenuse  12 cm is  5.7 cm.

A triangle with one angle at \(90^o\) is called right angle triangle.

Given that:

Hypotenuse = 12 cm

\(\theta = 62^o\)

The length of side AB in the given right angle triangle is calculated as:

Using trigonometric function,

\(\cos\theta = \dfrac{base}{hypotenuse}\)

Let, the value of base be x

Substitute the values in the given formula:

\(\cos 62^o = \dfrac{x}{12}\)

Using the trigonometric table, the value of \(\cos 62^o\) is 0.4694

\(0.4694 \times 12\)= x

x= 5.6328

x = 5.7

Thus, the length of side AB to 1 decimal place is 5.7 cm

Answer:

Step-by-step explanation:

The solution of the system of the equation is x = -3 and y = 5. And the intersecting point in the graph is solution point.

One or many equations having the same number of unknowns that can be solved simultaneously called as simultaneous equation. And simultaneous equation is the system of equation.

We have the system of equations:

y = x+8   equation 1

y = −2x−1     equation 2

In order to solve the problem:

Subtract the equation 2 with the  equation 1,

-2x-x -1-8 = 0

-3x = 9

x = -3

And y = 5

Graphically, the intersection point of both lines is the solution of the system.

The graph is given in the attached image.

Therefore, the solution of the system of the equation is x = -3 and y = 5.

The answer is: x+x^4

Answer:

Either \(77.5^{o}\) or \(102.5^{o}\)

Step-by-step explanation:

Given that : one angle is \(25^{0}\) greater than another. Let the two angles be represented by a and b. Since one angle is \(25^{0}\) greater than another, then:

b = a + \(25^{0}\)

But;

a + b = \(180^{o}\) (sum of angles on a straight line)

a + a + \(25^{0}\) = \(180^{o}\)

2a = \(180^{o}\) - \(25^{0}\)

a = \(77.5^{o}\)

b =  \(77.5^{o}\) + \(25^{0}\) = \(102.5^{o}\)

Therefore the measures of all angles formed by the lines is either \(77.5^{o}\) or \(102.5^{o}\).

The coefficient of variation (CV) is a measure of relative variability and is calculated by dividing the standard deviation by the mean, and then multiplying by 100 to express it as a percentage.

In this case, the mean weight is 340 grams, and the standard deviation is 5.2 grams.

CV = (Standard Deviation / Mean) * 100

CV = (5.2 / 340) * 100

CV ≈ 1.53%

Explanation:

The probability of success remains constant from trial to trial, and subsequent trials are independent. A binomial distribution, which results from counting successes over a series of trials, has only two possible outcomes on each trial

The likelihood of success is constant from trial to trial, and subsequent trials are independent. A binomial distribution, which derives from counting successes across a series of trials, has just two possible outcomes on each trial.

It is a distribution style with two potential results. Coin flipping is a common use of binomial distribution. There are just two possible outcomes from a coin toss: heads or tails, and each has an equal probability of 50%.

The probabilities of each of the two occurrences are multiplied together to yield the probability of two independent events, and, both occurring: P (A) P (B) = P (A a n d B).

The Production Possibility Frontier (PPF) is often called the "Opportunity Cost Curve" because it illustrates the concept of opportunity cost.

Opportunity cost is the cost of one alternative in terms of the benefits forgone of the best alternative. In other words, it's the cost of one choice in terms of the best alternative choice.

As we move along the PPF, we can see that as we produce more of one good, we must give up some production of the other good. This trade-off is represented by the slope of the PPF, which is the opportunity cost of producing one good in terms of the other good. The PPF illustrates the relationship between production and opportunity cost by showing the trade-offs that must be made and the opportunity costs associated with different production choices.

What is a system of equations?

A finite set of equations for which common solutions are sought is referred to in mathematics as a set of simultaneous equations, often known as a system of equations or an equation system.

Here, we have

Given: 3a - 5b = -26, a + 2b = 6

We have to solve this equation.

3a - 5b = -26...(1)

a + 2b = 6...(2)

Now we multiply equation (1) by 2 and equation (2) by 5 and we get

6a - 10b = -52....(3)

5a + 10b = 30....(4)

After solving equations (3) and (4), we get

11a = -22

a = -2

Now we put the value of 'a' in equation(3) and we get

6(-2) - 10b = -52

-10b = -52 + 12

-10b =  -30

b = 3

Hence, the value of a = -2 and b = 3.
