The inequality that represents the graph is y ≤ -x - 2.

In mathematics, inequality is a declaration of an order connection between two numbers or algebraic expressions (greater than, greater than or equal to, less than, or less than or equal to).

In the graph, we have

1. the line is going down (negative slope) so that's why u have the negative

2. it translated 2 units Downwards on the y-axis so that's why there is - 2

3. the line is Solid so it's going to have the equal sign under it, if the line was dashed it would just be a regular sign fr example (<)

4. the shading is below the line so that means it's going to be Less than or Equal to.

The approximate distribution (give distribution name and parameters) of the total length will be =  450 minutes

The estimated distribution of the total length of Tina's simulation study is a triangular distribution with a base worth of 2 minutes, a greatest worth of 4 minutes, and a mode (most reasonable worth) of (2+4)/2 = 3 minutes.

Since the simulation time is generally consistently distributed somewhere in the range of 2 and 4 minutes, the total simulation time will be the sum of 150 free random variables each with a triangular distribution.

Hence, the total simulation time will also have a triangular distribution with a base worth of 2 minutes x 150 = 300 minutes, a greatest worth of 4 minutes x 150 = 600 minutes, and a method of (300+600)/2 = 450 minutes.

As ΔABC ≅ ΔDEF, Using congruence properties the value of x= 5 and the value of y= 14.

Congruent triangles are two triangles that are the same size and shape. Two congruent triangles remain congruent even if we flip, turn, or rotate one of them. Two triangles must have the same angles and, as a result, must be congruent if their sides are the same.

Given that ΔABC ≅ ΔDEF, so that

AB ≅ DE

BC ≅ EF

AC ≅ DF

and AB = 8

BC = 19

AC = 14

EF = 4x-1

DE = y-6,

As AB ≅ DE

8 = y - 6

add 6 both sides we get

y = 8 + 6

y = 14

and BC ≅ EF

19 = 4x - 1

Add 1 both sides we get

4x = 19 + 1

4x = 20

divide both sides by 4 we get

x = 20/4

x = 5

The value of exterior angle is 108°.

What are exterior angles ?
An exterior angle is an angle which is formed by one of the sides of any closed shape structure such as polygon and the extension of its adjacent side.

Given:

Interior angles : (a+10)° and 44°

Thus , we know that

Exterior angle  = sum of interior opposite angles

Therefore , Exterior angle  = (a+10)° + 44°

or

2a° = (a+10)° + 44°

or

a = 54°

Therefore , exterior angle = 2a = 2*54° = 108°

The student took his resting pulse rate by counting the number of beats in 20 seconds. He then multiplied his result by three to calculate his pulse rate for a minute. To determine if his pulse rate was within the normal range for children, he compared his result to the data shown in the table. His pulse rate of 120 beats per minute was within the range of 60-100 beats per minute, so it was considered to be normal for children. To ensure accuracy, the student could have taken his pulse rate for a longer period of time, such as 30 or 60 seconds, before calculating his pulse rate for a minute.

So, approximately 2.28% of the observations are less than 140.

To find the percentage of observations that are less than 140, we need to find the standard score (z-score) that corresponds to 140, and then use a standard normal table to find the proportion of data that is less than that z-score.

The standard score is calculated as follows:

z = (140 - 130) / 5 = 2

Using a standard normal table, we can find the proportion of data that is less than 2 standard deviations from the mean. This proportion is approximately 0.0228 or 2.28%.

Mean is nothing but the average of data.

Resolviendo un sistema de ecuaciones, veremos que que la piedra estuvo 7 segundos en el aire y 5 en el agua.

Sabemos que:

En el aire tuvo una velocidad promedio de 16 m/s. En el agua tuvo una velocidad promedio de 3 m/s antes de tocar el fondo del mar.

Definamos las variables:

x = tiempo que la piedra estuvo en el aire.

y = tiempo que la piedra estuvo en el agua.

Sabemos que el trayecto completo duro 12 segundos, entonces podemos escribir:

x + y = 12

Y la caida total fueron 127 metros, entonces:

x*16 + y*3 = 127

Entonces tenemos un pequeño sistema de ecuaciones:

x + y = 12

x*16 + y*3 = 127

En la primera podemos aislar x:

x = 12 - y

Reemplazar eso en la otra ecuacion:

(12 - y)*16 + y*3 = 127

192 - 13y = 127

192 - 127 = 13y

The table that represents a linear relationship that is also proportional is; Table B

In Mathematics, a proportional relationship can be defined as a type of relationship that generates equivalent ratios and as such it can be modeled or represented by the following mathematical expression:

y = kx

Where:

x and y represents the variables.

k represents the constant of proportionality.

For us to have a proportional relationship and equivalent ratios, the variables x and y must have the same constant of proportionality.

Next, we would determine the constant of proportionality (k) using table B as follows:

Constant of proportionality (k) = y/x

Constant of proportionality (k) = -2/-1 = 2 or 2/1 = 2

Constant of proportionality (k) = 2

The decimal number that corresponds to the binary number 11111111 is 255.

The decimal numeral system is the most widely used system for representing both integer and non-integer values. It is the Hindu-Arabic numeral system's expansion to non-integer numbers. Decimal notation is the method of representing numbers in the decimal system. A decimal number is made up of two parts: a whole number and a fractional component separated by a decimal point. The decimal point is the dot between the whole number and the fractions. 25.5, for example, is a decimal number.

Here,

In binary, each digit represents a power of 2, starting with the rightmost digit. The rightmost digit in 11111111 represents 2^0, the second digit from the right represents 2^1, and so on. To convert a binary number to decimal, you add up the value of each digit times the corresponding power of 2.

For 11111111, the calculation would be:

=1 * 2^7 + 1 * 2^6 + 1 * 2^5 + 1 * 2^4 + 1 * 2^3 + 1 * 2^2 + 1 * 2^1 + 1 * 2^0 = 128 + 64 + 32 + 16 + 8 + 4 + 2 + 1

An equation is a mathematical term, which indicates that the value of two algebraic expressions are equal. There are various parts of an equation which are, coefficients, variables, constants, terms, operators, expressions, and equal to sign.

For example, 3x+2y=0.

Types of equation

1. Linear Equation

2. Quadratic Equation

3. Cubic Equation

Luke realized that squaring each side of the equation √(3-x) = -16 would lead to an extraneous solution. This happens because squaring each side of the equation changes the direction of the inequality, which may result in solutions that do not actually satisfy the original equation.

The square root of any positive number is always positive, so the left side of the equation is always non-negative. However, -16 is a negative number, so there is no real solution to the equation √(3-x) = -16.

1 furlong, a unit used in horse racing, is equal to 40 rods and 10 chains, both units used in surveying and equal to 201.168 meters (660 feet).

A furlong is a unit of length used primarily in horse racing. It is equal to 201.168 meters (660 feet). A rod is a unit of length used in surveying and is equal to 5.5 yards (16.5 feet). A chain is also a unit of length used in surveying and is equal to 66 feet.

To calculate 1 furlong in rods, we multiply 1 furlong by the conversion factor of 40 rods per furlong:

1 furlong x 40 rods/furlong

= 40 rods

To calculate 1 furlong in chains, we multiply 1 furlong by the conversion factor of 10 chains per furlong:

1 furlong x 10 chains/furlong

= 10 chains

To convert from furlongs to rods, we multiply the number of furlongs by the conversion factor of 40 rods per furlong:

4.0 furlongs x 40 rods/furlong = 160 rods
