❀ Explanation :

✑ Let's Know about A.M ( Arithmetic Mean )

In statistics , a single number can be calculated from a group of data which shows the character of the whole data. This number is called the average of the while data. An average is also called the arithmethic mean or simply mean which is a measure of central tendency.

☄ To calculate the average of the given type of data ( discrete series )  , follow the steps given below :

✐ Remember :

[tex] \underline{ \boxed{ \sf{mean \: = \frac{Σfx}{Σf} \: or \: \frac{Σfx}{n}}}} [/tex]

Where , Σf = N = Sum of the frequency and the symbol ' Σ ' ( sigma ) means " summation of " .

Answer:

The probability is 1/36

Step-by-step explanation:

Since we have two dies rolled together, the sample space is 36

What we mean by the sample space is the number of total possible results

So the total number of results that we can get is 36

Out of all our result, 3,3 can only appear once

so the probability of getting 3,3 on both dice is 1/36

Answer:

1/36

Step-by-step explanation:

You could do Pythagorean theorem which is:

[tex] {a}^{2} + {b}^{2} = {c}^{2} \\ {8}^{2} + {4}^{2} = {c}^{2} \\{64} + {16} = {c}^{2} \\ \sqrt{80} = {c}^{2} \\ 4\sqrt{5} = c[/tex]

Answer:

tan 272 < 0 is the correct answer

Step-by-step explanation:

Firstly, we need to understand the quadrant in which we have the angle

Mathematically, angle 272 is on the 4th quadrant

On the 4th quadrant, only the cosine value is positive, sine and tangent values are negative

Hence, we have that tan 272 < 0

is the correct answer

Answer: A. tan 272° < 0

Answer:

x + y = 27

y = x - 3

Step-by-step explanation:

x = # of girls

y = # of boys

first there are a total of 27 students so # of girls plus # of boys has to be 27.

then number of boys is 3 less than number of girls. This means x - 3 = y or y = x-3

Answer:

2160 degrees

Step-by-step explanation:

The general equation to find the sum of interior angles in a polygon is;

[tex](n - 2) * 180[/tex]

Where "n" is the sides of the polygon.

Substitute in 14 for "n"

( 14 - 2 ) * 180

Solve;

( 14 - 2 ) * 180

12 * 180

Answer:

Step-by-step explanation:

Complete Question:

The given line segment has a midpoint at (3, 1). On a coordinate plane, a line goes through (2, 4), (3, 1), and (4, -2).

What is the equation, in slope-intercept form, of the perpendicular bisector of the given line segment?

Answer:

[tex]y = \frac{1}{3}x[/tex]

Step-by-step explanation:

From the question, we understand that the line goes through [tex](2, 4), (3, 1), and\ (4, -2).[/tex]

First, we calculate the slope of the above points

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

Where

[tex](x_1,y_1) = (2,4)[/tex]

[tex](x_2,y_2) = (3,1)[/tex]

[tex]m = \frac{1 - 4}{3 - 2}[/tex]

[tex]m = \frac{-3}{1}[/tex]

[tex]m = -3[/tex]

Also; from the question, we understand that the line segment is perpendicular to the above points.

This slope (m2) of the line segment is calculated as:

[tex]m_2 = -\frac{1}{m}[/tex]

Substitute -3 for m

[tex]m_2 = -\frac{1}{-3}[/tex]

[tex]m_2 = \frac{1}{3}[/tex]

Lastly, we calculate the equation of the line using:

[tex]y - y_1 = m_2(x - x_1)[/tex]

The line segment has a midpoint at (3, 1)

So:

[tex]y - 1 = \frac{1}{3}(x - 3)[/tex]

Open bracket

[tex]y - 1 = \frac{1}{3}x - 1[/tex]

Add 1 to both sides

[tex]y - 1 +1= \frac{1}{3}x - 1+1[/tex]

[tex]y = \frac{1}{3}x[/tex]

Hence, the equation of the line segment is: [tex]y = \frac{1}{3}x[/tex]

A. y = One-thirdx

2020 Edge

Answer:

Original function;

y = logbX

Transformation;

y = -5/3logb(x + 2) - 6

Step-by-step explanation:

General form of a logarithmic function is given below;

y = logb X (log to base b)

Reflection over the y-axis

y value remains same, x becomes negative

y = - logb X

Vertical stretch by a factor of 5/3

This means that we multiply the whole function by 5/3

That will be;

y = -5/3logbX

Transformation right 2 units

This means that we add the value of 2 to the x-axis value

y = -5/3logb(x + 2)

transformation down 6 units

This means that we subtract 6 from the total y value

y = -5/3logb(x + 2) - 6

the answer is 34.

Answer:

7x - 6

General Formulas and Concepts:

Pre-Algebra

Algebra I

Step-by-step explanation:

Step 1: Define

5x + 2(x - 3)

Step 2: Simplify

Combining like terms is a process where you combine the terms with the same variable and/or exponent.

Let's say that we have an expression 3p + 3q. We can't combine the like terms, because 3p and 3q have different variables.

Now, what is the distributive property?

The distributive property is a property used for multiplying a monomial by a binomial or trinomial by "distributing" the monomial. The distributive property has a formula, which is:

[tex]\sf{a(b+c)=ab+ac}[/tex]

Here, a got multiplied by b and c.

Similarly, we combine the terms:

[tex]\sf{5x+2(x-3)}[/tex]

Simplify:

[tex]\sf{5x+2x-6}[/tex]

Combine like terms:

[tex]\sf{7x-6}[/tex]

Hence, the simplified answer is 7x - 6.

Answer:

x = 55 degrees

Step-by-step explanation:

180 - 164 = 16. 16 + 109 = 125. A triangle's angles should add up to 180, so to find the value of x, subtract 180 by 125 and you'll get 55.
