Answer:

Parallel" means same slope. Our line is y=3x-4 has slope m=3. So, our new line should also have slope m=3; we can immediately eliminated choices C and D.

Step-by-step explanation:

We can write our line y = 3x+b, and we can use the point given (3,2) to solve for b.

2 = 3*3 + b

b = -7

The required line is y = 3x - 7, choice B.

Answer:

55.866 ft

Step-by-step explanation:

Use Pythagorean Theorem:

a² + b² = c²

(39)² + (40)² = c²

3121 = c²

Square root of both sides

c = 55.866 ft should be the answer.

The f(x) is shifted 4 units up to g(x) is the correct choice because f(x) is up 4 units from the g(x) option (D) is correct.

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have a function:

f(x) = cosx

The above function is a parent function.

Transformed function:

f(x) = cosx - 4

As we can see in the graph of, g(x) is shifted 4 units down from the function f(x).

Thus, the f(x) is shifted 4 units up to g(x) is the correct choice because f(x) is up 4 units from the g(x) option (D) is correct.

Step-by-step explanation:

Using the formula for the closest integer, it is found that Alejandro is not correct, as the integer is of 48 and not 52.

The integer that has square root n is given by:

S(n) = n².

Hence the integer that has a square root closest to n is given by:

C(n) = n² - 1.

In this problem, we want the square root closest to n = 7, hence:

C(7) = 7² - 1 = 48.

Which is a different value than 52, hence Alejandro is not correct.

The mean, median and mode of the data sets are as follows:

The median is the middle value in a list ordered from smallest to largest.

The mode is the most frequently occurring value on the list.

The mean is the average of the distribution.

Therefore,

1. 1, 2, 3, 4, 5

mean = 1 + 1 + 2+ 3 + 4 + 5 / 6 = 16 / 6 = 2.7

median = 2 + 3 / 2 = 5 / 2  = 2.5

mode = 1

Answer: A large mean difference and small sample variances ​

Step-by-step explanation:

Effect size (η) is a statistical measure that determines the strength of the association (numerically) between two variables.  For example, if we have data on the weight of male and female candidates and we realize that, on average, males are heavier than females, the difference between the weight of males and the weight of female candidates is known as the effect size.

The larger the effect size, the larger the weight difference between males and females will be.  

Statistic effect size helps us in analyzing if the difference is factual or if it is affected by a change of factors.  

In hypothesis testing, effect size, power, sample size, and critical significance level are related to each other.

The effect size formula for a hypothesis test of mean difference is:

η = [tex]\frac{x1-x2}{\sqrt[]{8^2} }[/tex]

The denominator s² is the combined sample variance.

[tex]8^2 =[/tex] ⊕

The effect size is affected by two components:

Sample mean difference

Sample variance.

As the sample mean difference is directly proportional to the effect size, on increasing the sample mean difference value the effect size will also increase.

Ans the sample variance is inversely proportional to the the effect size, on decreasing the sample variance value the effect size will increase and vice-versa.

Thus, the correct option is A large mean difference and small sample variances

Both words are used to talk about how long the boundary is of a 2D figure.  Think of circumference as a special case of finding the perimeter.  The term circumference refers to the perimeter of a figure without sides or something like a circle or arc.

So if we were to look at a rectangle and try to determine how long the boundary is we would use perimeter.  On the other hand, if we have a circle we have no way to track how long each side is therefore we use circumference.

Perimeter is a wide term which means the total length of the surrounding (lines ) of the 2D figure.

circumference is the special case of the perimeter in which perimeter of Arc or circular lines are taken in count .
