What is the arithmetic operation?

The four fundamental operations of arithmetic are addition, subtraction, multiplication, and division of two or more quantities. Included in them is the study of numbers, especially the order of operations, which is important for all other areas of mathematics, including algebra, data management, and geometry. The rules of arithmetic operations are required in order to answer the problem.

The depth of the water when the wave speed is 200 meters per second is 4081.63m

Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object's movement.

Given,

In a tsunami, the wave speeds (in meters per second) can be modeled by s(d)=√9.8d,

Where d is the depth

We need to find the depth when speed is 200 meters per second

s(d)=√9.8d,

200=√9.8d,

Square on both sides

40000=9.8d

Now divide both sides by 9.8

d=4081.63m

Hence, the depth of the water when the wave speed is 200 meters per second is 4081.63m

The one which uses Sir Ronald Fisher's F-distribution for the test statistic is to compare several population means simultaneously.

The F-distribution was developed by Sir Ronald Fisher to study the behavior of two variances from random samples taken from two independent normal populations. The F-distribution allows us to use a F statistic to compare two populations.

The F-distribution is also known as a right-skewed distribution used commonly in another statistical test called an Analysis of Variance (ANOVA). For ANOVA tests we can use the F-distribution to check whether the variance among the means of two populations significantly differ. The F-distribution can also be used in regression analysis to compare the fit of different models.

Answer:

A. Linear

B. Non-linear

C. Linear

Step-by-step explanation:

A linear line has a consistent slope either going down (negative) or going up (positive.)

A. The x values are increasing by a constant rate of 1, and the y values are decreasing at a constant rate of 1. Therefore it is a linear relation.

B. The x values are increasing by a constant rate of 1, but the y-value repeats itself twice in the second and third column. Therefore it does not have a consistent slope and is not a linear relation.

C. The x values are increasing by a constant rate of 1, and the y- values increase by a constant rate of 2 except in column 4 making it a non-linear relation.

Answer:

x=1, y=-3

Step-by-step explanation:

We first see there is a 3y in both equations. We can completely eliminate the y term by subtracting the equations.[tex](4x+3y=-5)-(-x+3y=-10)[/tex]. This gives us (4x--x)=(-5--10), which is 5x = 5. So, x = 1.

Using the distributive property, the greatest common factor of  75+20 is 5(15+4).

The distributive property of binary operations in mathematics generalizes the distributive law, which states that in elementary algebra, equality is always true.

For instance, in basic mathematics, one has to According to one, addition is distributed more evenly than multiplication.

So, the largest number that will split two values is the greatest common factor. Two values are available: 75 and 20.

Each has a set of numbers that when added together equal the total.

We must identify the most important quality or area where they most agree.

Each possesses the following elements:

75: 1,3,5,15,25, 75

20: 1, 2, 4, 5, 10, 20

Each has 5, making this the GCF.

As a result, we write the expression as 5(_+_).

We calculate the matching factor by multiplying each term by 5.

75/5= 15

A null hypothesis proposes that certain characteristics of a population or development process are the same regardless of whether they differ or not. There is a difference, according to the alternative hypothesis. A null hypothesis can be rejected with a certain degree of confidence through hypothesis testing.

The alternative hypothesis can be supported if the null hypothesis is rejected. A null hypothesis test is a basis for science's falsification principle.

Answer:x=-5

Step-by-step explanation:

Answer:

• Area of parallelogram = 270 in.²

• Area of square = 225 in.²

• Area of composite figure = 495 in.²

Step-by-step explanation:

We are given a composite figure made up of a parallelogram and a square and told to find its area.

To do this, we are told first to find the area of the parallelogram. The formula for the area of a parallelogram is:

[tex]\boxed{\mathrm{Area \ of \ parallelogram = base \times height}}[/tex].

From the figure, we can see that, for the parallelogram, height = 18 in. and base = 15 in. (since opposite sides of a parallelogram are equal).

Using this information, we can calculate the area of the parallelogram:
Area = base × height

        = 15 in. × 18 in.

        = 270 in.²

Next, we have to find the area of the square using the formula:

[tex]\boxed{\mathrm{Area \ of \ square = side \times side}}[/tex].

From the figure, we can see that the length of a side of the square is 15 in.

Therefore, using the formula above, we can calculate the area of the square:

Area = side × side

        = 15 in. × 15 in.

        = 225 in.²

Now that we know the respective areas of the two shapes that make up the composite shape, we simply have to add the areas together:

Area of composite figure = 270 in² + 225 in²

                                          = 495 in.²

The maximum error in the calculated area of the disk is 33.93 square cm. The relative error is 0.0148. The percentage error is 1.48%.

a. The area [tex]$\mathrm{A}$[/tex] of a circle with radius [tex]$\mathrm{r}$[/tex] is given by the following formula from Geometry:

[tex]$A=\pi r^2$[/tex]

The question provides us the following information:

radius [tex]$r=27 \mathrm{~cm}$[/tex], maximum radius measurement error [tex]$\Delta r=0.2 \mathrm{~cm}$[/tex]

Using linear differentials we get the error in the calculation of the area of this disk [tex]$\Delta A$[/tex] from (1) as follows:

[tex]$\Delta A=2 \pi r \Delta r \Longrightarrow|\Delta A|=2 \pi r|\Delta r|$[/tex]

Using the information from (2) in (3) yields

[tex]$|\Delta A|=2 \pi(27)(0.2)=33.93 \mathrm{~cm}^2 \text {. }$$[/tex]

The maximum error in the calculated area of the disk is 33.93 square [tex]$\mathrm{cm}$[/tex].

b. The relative error is calculated using (1) and [tex]$r=27 \mathrm{~cm}$[/tex] as follows:

Relative Error [tex]$=\frac{|\Delta A|}{A}=\frac{33.93}{\pi\left(27^2\right)}=0.0148$[/tex].
