What is ANOVA ?

Analysis of variance (ANOVA) is a statistical technique for examining variations in means. It consists of a number of statistical models and the estimating techniques they require. The statistician Ronald Fisher is credited with creating the ANOVA. According to the law of total variance, which is the foundation of ANOVA, the observed variance in a given variable is divided into components that can be attributed to various causes of variation. ANOVA generalizes the t-test beyond two means by offering a straightforward statistical test for the equality of two or more population means. In other words, the ANOVA is employed to compare two or more means.

Therefore, the correct answer is analysis of variance.

Answer:

x = 4√104/2

Step-by-step explanation:

The data shows a negative linear association between the number of magazines checked out and the number of books checked out.

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

Scatter plots are used to plot data points on a horizontal and a vertical axis in the attempt to show how much one variable is affected by another.

If one variable tends to increase as the other decreases, the association is negative.

By observing the scaterplot we understand that the value is decreasing as the other value is increasing.

Hence, The data shows a negative linear association between the number of magazines checked out and the number of books checked out.

Using the inverse proportion formula, the value of the second quantity y in the question is (D) 27.

One kind of proportionality relationship is inverse proportion.

If two quantities are inversely related, one will increase while the other will decrease.

Building a wall would be an example of an inverse proportion in action.

On the other hand, in indirect or inverse proportion, if one quantity rises, the other one falls, and vice versa.

So, the value of the second quantity will be:

The formula for inverse proportion:

y = k/x ...(1)

Pur x = 15 and y = 18 in (1) as follows:

15 = k/15

× 15 on both sides:

15 × 15 = k/15 × 15

k = 270

Now, obtain y as follows using the same process:

Let, x = 10 and k = 270:

y = k/x

y = 270/10

y = 27

Therefore, using the inverse proportion formula, the value of the second quantity y in the question is (D) 27.

The expression 1/8¹⁴ is equivalent to 8⁻¹⁰ / (8⁴)(8⁰). The 1st option is the answer

Index ( plural indices) is the power or exponent which is raised to a number or a variable e.g in number 3⁵, 5 is the index of 3.

Given: the expression 8⁻¹⁰ / (8⁴)(8⁰)

8⁻¹⁰ / (8⁴)(8⁰) can be written as:

8⁻¹⁰ / (8⁴)(8⁰) = 8⁻¹⁰ / (8⁴)(1)          (Note: 8⁰ = 1)

                     = 8⁻¹⁰ / 8⁴               (Note:  1/8⁴ = 8⁻⁴  )

                     =  8⁻¹⁰ × 8⁻⁴

                     = 8⁻¹⁰ ⁺ ⁻⁴

                     = 8⁻¹⁴

What is area ?

Area is a mathematical concept that expresses the size of a region on a planar or curved surface. The area of an open surface or the boundary of a three-dimensional object is referred to as the surface area, whereas the area of a plane region or plane area refers to the area of a form or planar lamina.

The term "area" refers to the amount of space occupied by a 2D form or surface. We use cm2 or m2 as our units for measuring area. A shape's area is determined by dividing its length by its width.

440/4 = 110 x 110 feet

The probability having of 3 boys and 4 girls is 33 or 0.33

what is probability?

The area of mathematics known as probability deals with numerical descriptions of how likely it is for an event to happen or for a proposition to be true. A number between 0 and 1 is the probability of an event, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes its certainty.

solution:

Assuming 50/50 chance on boy/girl we see following outcome:

(1/2^7).

Since there is only one way you can have 3 girls, followed by 4 boys.

If you would tell the boys apart, and the girls, for instance by their names, the probability would be:

6 * (1/2)^3 *(1/2)^4 * 24.

6 Times because the girls would then have 6 orders of having been born.

24  Times because then the boys would have 24 orders of having been born.

Answer: yes

Step-by-step explanation:

The approximate area between y=3x^(2)+1 and the x-axis on the interval -1 to 5 is 136.6875.

We can approximate the area between y=3x^(2)+1 and the x-axis on the interval -1 to 5 using a Riemann sum with 4 rectangles of equal width. The left-hand endpoint of each subinterval will be used.

The width of each rectangle is the length of the interval (5-(-1)) divided by the number of rectangles (4). Therefore, the width of each rectangle is

(5-(-1))/4 = 6/4 = 1.5.

Since we are using the left-hand endpoint of each subinterval, the x-values of the left-hand endpoints of the rectangles are

-1, -1+1.5

-1+1.5+1.5

-1+1.5+1.5+1.5 = -1+4.5=3.5

The height of each rectangle is determined by the value of y at the corresponding x-value.

Therefore, the heights of the rectangles are

3(-1)^2+1=2

3(-1+1.5)^2+1=7.125

3(3.5)^2+1=35.125

3(3.5+1.5)^2+1=46.875

The area of each rectangle is the product of its width and height, so the areas of the rectangles are

2*1.5=3

7.125*1.5=10.6875

35.125*1.5=52.6875

46.875*1.5=70.3125.

Therefore, the approximate area between y=3x^(2)+1 and the x-axis on the interval -1 to 5 is 136.6875.

Here we need to find how many plates are possible.

Here we have given that, A license plate composed of 2 letters followed by 4 digits.

The first step is considering the letters in the plate.

Here we know that, the plate consists of 2 letters.

And in alphabets, we have 26 letters which start from A to Z.

Therefore, we can choose 2 letters from 26 letters in 26² ways.

Now, we considering the digits in the plate.

The CY in the given Parallelogram WXYZ is 15 ft.

A parallelogram is defined as, "A geometrical figure whose sides are parallel to each other. "
In the given Parallelogram WXYZ, the length of the sides is not given. Although, the length of the two diagonal sides is given which are CY and CW with a variable x. The following are the values of these two diagonals:
CY = (2x -  7) ft                  .....(1)
CW = (x + 4) ft                   ......(2)

In this given question, we need to find the value of CY. So, we can find the value of CY by finding the value of variable x.

To find the value of x, we follow the theorem:
"In the parallelogram, The diagonals bisect each other"
We get that,
CY = CW                       ......(3)
By putting the value equation (1) and (2) in equation (3), we get
2x - 7 = x + 4                    ......(1)
By subtracting 'x' and adding '7' on both sides of the equation.
x = 11,
So we get,

x = 11.
By putting the value of 'x' in equation (1), we get:

CY  = 2(11) - 7 =  11 - 7
CY = 4.

Hence, the value of CY is 4.
