For this analysis, 4/25 is the f-ratio.
What is f- ratio?
In the psychosocial, behavioral, and health sciences, the F-ratio is frequently employed in study on quality of life. In order to compare two or more groups, it often refers to a statistic that is produced by dividing two sample variances that are supposed to come from normally distributed populations.SS between = 30
SS within = 60
Mean square of regression = 30/2 = 15
Mean square of error = 60/15 = 4
So f ratio = 15/4 = 3.75
So it's answer is D.
Solution(15)
Df between = Df total - Df within = 29-27 = 2
So it's answer is b. I.e. 2
Solution(16)
If Df = 18 and there are two independent sample than total sample size = 18+2 = 20
So it's answer is A
Solution(17)
N1=10
N2 = 15
So DF = 10+15-2 = 23
So it's answer is C. I.e. 23
Solution(18)
D = (M1-M2)/spooled = (35-31)/25 = 4/25

32+(-17) is 17 units from 32, in the positive direction
On the number line, It is true to the claim that the solution to the expression 32 + (-17) is 17 units from 32 in the positive direction.
What is a number line?A number line is an illustration of a graded straight line that represents actual numbers. What we call a "number line" is really a horizontal line with regularly spaced number increments. The number line's response format is determined by the numbers it contains.
All possible numbers may be plotted along a line called a number line. Any real number may be represented by a single dot on a number line.
On the number line, we have the negative numbers on the -ve x-axis to the left and they are smaller than the positive numbers to the right, and this is immediately apparent when looking at a number line.
Given that:
= 32 + (-17)
= 32 - 17
= 17
We can therefore conclude that the given expression shows that we are 17 units far away from 32 in the positive x-axis on the number line.

☐E) Triangle VWZ is equilateral.
OF) Each side of triangle VWZ is composed of two radii that have the same

The true statements are: (A), (D), (E) and (F).
Statement A is true. A triangle is said to be isosceles if its two sides are of equal length. Considering the triangle STU, the sides ST and TU are the radius of the same circle centered at T and hence of same length. So triangle STU is isosceles.
Statement B is false. In triangle STU, ST and TU being radii of circle T, are equal. But the third side SU is not a radius of any circle in the diagram and so not equal to ST and TU. Since three sides are not of same length, triangle STU is not an equilateral triangle.
Statement C is false. In Triangle STU two sides are composed of a single radii and not of two radii. The third side is not composed of radii.
Statement D is true. In triangle STU, two sides are radii of circle T but the third side, segment SU, is not a radius of any circle shown in the diagram.
Statement E is true. In triangle VWZ, each side is composed of 2 radii which are of same length. Hence three sides are equal and so it is an equilateral triangle.
Statement F is true. Each side of triangle VWZ is composed of two radii that have the same length.

System of EquationsA system of equations is the given term math for two or more equations with the same variables. The solution of these equations represents the point of the intersection.
You can solve a system of equations by the adding or substitution methods. In the addition method, you eliminate a variable, on the other hand, in the substitution method you replace a variable for the other.
First, you should convert the text of the question into a math expression. Then,
Javier pagó $92 por 5 libretas y 3 lápices. You can represent this text as the equation:5B+3L=92, where B= libretas and L=lápices.
Laura compró 2 libretas y 6 lápices, y pagó $56. You can represent this text as the equation:2B+6L=56, where B= libretas and L=lápices.
Therefore,
5B+3L=92 (1)
2B+6L=56 (2)
After that, you should multiply equation(1) by -2. Thus,
-10B-6L=-184(1)
2B+6L=56 (2)
Now, when you sum equations 1 and 2, you eliminate L . Thus, from this sum, you will have:
-8B=-128
B=128/8
B=16
If B=16, from equation 2, you can find L.
2B+6L=56 (2)
2*16+6L=56
32+6L=56
6L=56-32
6L=24

a researcher may claim a causal relationship between variables if one variable influences another. please select the best answer from the choices provided t f
The claim that a researcher may infer a causal link between variables if one effects another is False.
What do you mean when you say that variables have casual relationships?If a change in one variable's level results in a change in the other variable, then there is a causal relationship between the two variables. Keep in mind that correlation does not always imply causation. Two variables may be linked together without one of them directly contributing to the other's observable behavior.
For instance,
the chart below illustrates the relationship between ice cream sales and temperature. Any business can utilize the concept of causality. As is clear from the graph, there is a correlation between warmer weather and increased sales.
A casual relationship between two variables only exists when one of the variables actually causes the other to exist, which does not appear to be the case here. Instead, since a change in one variable affects the other, this scenario can be thought of as a correlated relationship.

The total proportion of shirts between two prices is 0.9431, which is obtained using the knowledge of proportion and statistics.
What is proportion?
In mathematics, a proportion is defined as the comparison between two numerical quantities. If both possess the same nature, they are called directly proportional, or else called inversely proportional.
Calculation of the proportion based on the problem
The mean and standard deviation are given to be 45 and 5 respectively
Calculate standard normal variate using the formula, z = (x - 45) / 5
Taking x = 37, we get,
z1 = (37 - 45) / 5
= -1.6
Using the z table, we get the value, z1 = 0.0548
Now, taking x = 59.35, we get,
z2 = (59.35 - 45) / 5
= 2.87
Using the z table, we get the value, z2 = 0.9979
The proportion between two prices is given by z = z2 - z1
z = 0.9979 - 0.0548
= 0.9431
Hence, the proportion of shirts between the two prices is 0.9431.
