We utilize a two factors, independent measurements ANOVA, where, factor has 2 level and a factor likewise has 2 levels.
What are factors?A factor in mathematics is an integer that evenly divides another number by itself, leaving no residue.
Factors and multiples are a part of our daily life. For example, they are employed in arranging objects in a box, handling money, recognizing patterns in numbers, solving ratios, and working with expanding
A number totally divides the provided number without leaving any residual is said to be the factor of that number.
The components of a number might be positive or negative. For example, let us find the factors of 8. Since 8 is divisible by 1, 2, 4, and 8, we may list the positive factors of 8 as, 1, 2, 4, and 8. Apart from this, 8 has negative elements as well, which might be stated as, -1, -2, -4,
According to our question-
Degrees of freedom for the F-test of the two way ANOVA
In this case, we utilize an ANOVA with two independent variables and two factors, each with two levels.
So, here,

= B's level count is 2,
Moreover, n = sample size in each treatment condition is equal to 10.
So we have,
= df of the main effect A = ( - 1) = 2 - 1 = 1
= df of the main effect A = ( - 1) = 2 - 1 = 1
= df of interaction effect (A x B) = ( - 1)( - 1) ( - 1)
= (2-1)(2-1) (2-1)
= 1
And = df of within variation (i.e. error variation) =
= 2 x 2 x (10 - 1) (10 - 1)
= 36
Consequently, the df value for the F-ratio measuring factors-primary A's impact is

Why is standard deviation not a measure of central tendency ?
A standard deviation (or σ) is a tool to measure how dispersed the data is in relation to the mean. While, in statistics, a central tendency is a central or typical value for a probability distribution. Some of the most common measures of central tendency consist of the arithmetic mean, the median, and the mode. Deviation means a change or a distance. But change is always followed by the word 'from'. Hence standard deviation is a measure of change or the distance from a measure of central tendency- which is normally the mean. Hence, standard deviation is different from a measure of central tendency.

A pool technician recorded the water loss in the pool from a drain leak over time. Hours (x) 2 4 6 8 Water loss (gal) (y) 4 8 12 16 The water loss is proportional to the time. How long will it take the pool to lose 120 gallons of water?
Answer:
60 hours to lose 120 gallons of water.
Step-by-step explanation:
Make a spreadsheet of the data with 3 columns. The first will contain the hours and the second will contain the gallons of water lost. (attached). It would be useful to have a water loss rate, such as gallons lost per hour. So in the third column, take the gallons of water for that line and divide it by the hours for that same line. Do this for each of the line entries, as shown. The first thing to note is that they are all the same. Perfect! (and important). This means we can use the rate of 2 gallons per hour and multiply it by the number of hours to find the total water lost:
(Rate[gal/hr])x(Time[hr]) = Gallons water lost
The question is how mush time until 120 gallons are lost. The unknown is the hours, which we'll call x. Now we can set up the equation and solve for x:
(Rate[gal/hr])*(Time[hr]) = Gallons water lost
(2 gal/hr)*(x) = 120 gallons water
x = 60 hours to lose 120 gallons of water.

What is number line?
A number line is an image of numbers plotted on a straight line, either horizontally or vertically. We can compare numbers and execute simple arithmetic operations on them easily by writing the numbers down on a number line. The starting point of a number line is often regarded as zero (0). These numbers to the left of zero are all negative while the numbers just on right of zero are all positive. As a result, we can argue that on a number line, the value of numbers grows as we approach the right. The numbers on the right are therefore larger than the ones on the left, according to this statement.
An integer is positive if it exceeds zero and negative if it falls below zero. Zero is described as being neither positive nor negative.

what is half of 7 3/4 on a tape measure
So, the half of [tex]7\frac{3}{4}[/tex] is [tex]3\frac{7}{8}[/tex]. An improper fraction is a fraction where the numerator is greater than or equal to the denominator.
A fraction is a numerical value that represents a part of a whole. It is typically written as a ratio of two numbers, with a line separating the numerator and the denominator. For example, the fraction one-half can be written as 1/2. Fractions are often used to represent a part of a whole number or a part of a whole object, such as a pie that has been cut into several pieces.
To find half of 7 3/4 on a tape measure, we need to follow these steps:
Convert the mixed number 7 3/4 to an improper fraction. This can be done by multiplying the whole number, 7, by the denominator of the fraction, 4, and adding the numerator, 3, to the product. This gives us 7 x 4 + 3 = 31. So, 7 3/4 is equal to 31/4.Divide the numerator of the improper fraction by 2 to find half of the original mixed number. In this case, we divide 31 by 2 to get 31/2.Convert the resulting improper fraction, 31/2, back into a mixed number. To do this, we divide the numerator, 31, by the denominator, 2, and write the remainder, 1, as the numerator of the fraction part of the mixed number. This gives us the final answer of 3 7/8.Learn more about improper fraction, here https://brainly.com/question/21449807

What is Electric Flux?A feature of an electric field is electric flux. One way to conceptualize it is as the quantity of forces interacting in a specific space. According to conventional wisdom, electric field lines begin with positive electric charges and conclude with negative charges. A closed surface's field lines are seen as negative when they are directed into it, and as positive when they are directed out of it.Every field line that is directed into a closed surface continues through the interior and is often directed outward somewhere else on the surface if there is no net charge present within the surface. The net, or total, electric flux is zero because the size of the negative and positive fluxes are just about equal.A closed surface that contains a net charge will have a total flux that is proportional to the enclosed charge, positive if it is positive and negative if it is negative.To Learn more About flux across refer to:

the vertices of a triangle are A(-2,1), B(2,2) and C(6,-2). find the equation of the altitude AD drawn from A to BC
Answer:
To find the equation of the altitude from point A to side BC, we can use the formula for the equation of a line in point-slope form, which is:
y - y1 = m(x - x1)
where (x1, y1) is a point on the line, and m is the slope of the line.
We can find the slope of the line by using the formula for the slope of a line between two points:
m = (y2 - y1)/(x2 - x1)
We can use this formula to find the slope of line BC, which is the line connecting points B and C. Substituting the coordinates of these points into the formula gives us:
m = (2 - (-2))/(2 - 6) = 4/-4 = -1
Next, we can use the point-slope form of the equation of a line to find the equation of the altitude from point A to line BC. Substituting the coordinates of point A and the slope of line BC into the point-slope formula gives us:
y - 1 = -1(x + 2)
This is the equation of the altitude from point A to line BC.
