Answer:

-221 base 3

Step-by-step explanation:

We are to calculate the value of the numbers in base 3. One of the ways to do that is to first convert each number to base 10. Do the arithmetic, then convert back to base 3.

121 base 3 +2122 base 3 - 1200 base 3 - 2111 base 3

Let's convert to base10

See attachment for details

From the workings,

121 base 3 + 2122 base 3 - 1200 base 3 - 2111 base 3 = -221 base 3

The congruence of a right triangle is given by

a) HA

b) HL

c) LL

d) LA

Transformations change the size or position of shapes. Congruent shapes are identical, but may be reflected, rotated or translated. Scale factors can increase or decrease the size of a shape. Congruent Triangles simply mean the triangles that possess the same size and shape

The three sides are equal (SSS: side, side, side)

Two angles are the same and a corresponding side is the same (ASA: angle, side, angle)

Two sides are equal and the angle between the two sides is equal (SAS: side, angle, side)

A right angle, the hypotenuse and a corresponding side are equal (RHS, right angle, hypotenuse, side)

Given data ,

Let the triangles be represented as A and B

Now , the triangles are right angled and their congruency is given by

The hypotenuse-angle theorem, often known as the HA theorem, says that two right triangles are congruent if their hypotenuses and acute angles are parallel to one another.

Any two right triangles that have a congruent hypotenuse and a matching, congruent leg are congruent triangles, according to the HL, or hypotenuse-leg, theorem.

According to the LA, or leg-acute, theorem, a right triangle is congruent if its leg and any acute angle are congruent with the corresponding leg and acute angle of another right triangle.

Hence , the triangles are congruent

A normal distribution has its center at the mean and its spread is determined by the standard deviation. For the standard normal distribution, its mean is 0 and standard deviation is 1. It is in the shape of a bell curve. Most of the values fall in or around 0, forming the peak around this area. As you move away from 0, the values are less frequent which explains the drop-off. The distribution is continuous as you can have any real number (decimal or whole). It's also random because of the nature of statistics.

======> Mathematics <=======

Step-by-step :

the sum of all angles in the triangle is 180°, So =>

180° = 50° + 60° + x

180° = 110° + x

180° - 110° = x

70° = x

Answer:

The correct option is C.

C) The range represents the number of users each month for 36 months

Step-by-step explanation:

We have been given that:

x-axis ⇒ Number of Months

y-axis ⇒ Number of Users

x-axis values = 0 to 36

y-axis values = 0 to 60

We have a function which is represented by a straight line from (0,0) to (36,54).

We have to find the RANGE of the function.

Range of a function is a complete set of values of dependent variable y, for all possible values of independent variable x

As total number of months = 36

Range is the set of all values of y (Number of Users) for each month for a period of 36 months.

Hence, the correct option is C.

Answer:

D) The price of fish per pound

Step-by-step explanation:

A continuous data is one which can take any value . it can have even value between any two consecutive number.

Example :

continuous data can have value between 4 and 5 like 4.5 4.001 and so on.

Discrete data is one which can be counted such as number of flowers, no of cars in parking.

it can take value such as 1,2, 12, 66  etc.

____________________________________________

Let go through the option

A) The number of times you flip a coin

We can count the number of times a coin is flipped .

Like 2 times, 3 times and hence it is discrete data and not a continuous one.

B) The number of students in a classroom

Student in a classroom can also be counted.

in a class there can be 12, 50, 66 etc students not 12.1 , 50.5 etc.

hence it is discrete data and not a continuous one.

C) The number of chocolate candies in a box

Again, chocolate number can be counted .

Number of chocolate can be 2, 4, 5 and not 2.1 , 4.6 etc and

hence it is discrete data and not a continuous one.

D>The price of fish per pound

Price of fist cannot be counted . Further, price of fish can be $2.5 , $ 4.555

hence it is a continuous data.

Based on above discussion

continuous data is represented by The price of fish per pound

x = 5.6

Step-by-step explanation:

5x:8 = 7:2

First, find the relationship between 2 and 7.

2 x 3.5 = 7

Since the ratios are equal, this means:

8 x 3.5 = 5x

Solve algebraically. First simply 8 x 3.5

5x = 28

Divide both sides by 5

x = 5.6

Answer:

Option D.

Step-by-step explanation:

An inverse variation function is defined as

[tex]y\propto \dfrac{1}{x}[/tex]

[tex]y=\dfrac{k}{x}[/tex]

where, k is constant of proportionality.

In the above equation x represents input and y represents output.

If the function's input value is multiplied by 4, then

[tex]y_1=\dfrac{k}{x_1}[/tex]

[tex]y_1=\dfrac{k}{4x}[/tex]

[tex]y_1=\dfrac{1}{4}\cdot \dfrac{k}{x}[/tex]

[tex]y_1=\dfrac{1}{4}y[/tex]

The output is divided by 4​.

The required value of the expression [tex]\frac{a + 2bc}{3a}[/tex]  is 74 / 12 or   37 / 6 .

Given that,
The expression [tex]\frac{a + 2bc}{3a}[/tex]  is given, The value of the expression at a = 4, b = -5, and c = -7 is to be determined.

Here,
The given expression

Answer:

Step-by-step explanation:

-2 < n+3 ≤ 4

Make two separate equations,

-2 < n+3

Subtract 3 from both sides,

-2-3 < n + 3  -3

-5 < n

So, value of n should be greater than (-5)

n +3 ≤ 4

Subtract 3 from both sides

n ≤ 1

So, n value should be less than or equal to 1

So, n value should be greater than -5 and less than or equal to 1

n= { -4, -3 , -2 , -1 ,0 ,1 }

Answer:

Circumscribed circle: Around 80.95

Inscribed circle: Around 3.298

Step-by-step explanation:

Since C is a right angle, when the circle is circumscribed it will be an inscribed angle with a corresponding arc length of 2*90=180 degrees. This means that AB is the diameter of the circle. Since the cosine of an angle in a right triangle is equivalent to the length of the adjacent side divided by the length of the hypotenuse:

[tex]\cos 38= \dfrac{8}{AB} \\\\\\AB=\dfrac{8}{\cos 38}\approx 10.152[/tex]

To find the area of the circumscribed circle:

[tex]r=\dfrac{AB}{2}\approx 5.076 \\\\\\A=\pi r^2\approx 80.95[/tex]

To find the area of the inscribed circle, you need the length of AC, which you can find with the Pythagorean Theorem:

[tex]AC=\sqrt{10.152^2-8^2}\approx 6.25[/tex]

The area of the triangle is:

[tex]A=\dfrac{bh}{2}=\dfrac{8\cdot 6.25}{2}=25[/tex]

The semiperimeter of the triangle is:

[tex]\dfrac{10.152+6.25+8}{2}\approx 24.4[/tex]

The radius of the circle is therefore [tex]\dfrac{25}{24.4}\approx 1.025[/tex]

The area of the inscribed circle then is [tex]\pi\cdot (1.025)^2\approx 3.298[/tex].

Hope this helps!

Step-by-step explanation:

I think the first number is 2

Then 2 x 2 = 4 so there is a difference of 4 number

Then in between 6 and 14 there is a difference of 8 so 4 x 2 = 8

Then 16 so 8 x 2 = 16

So after 126 the number is 254

Answer:

X = C - By over A which also is A ≠ 0

Y = C - Ax over B which is also B ≠ 0

Step-by-step explanation:

Solve for x

First subtract "By" from both sides:

Ax + By - By = C - By

Then simplify,

Ax = C - By

Divide both sides by A:

Ax / A = C/A - By/A ; A≠0

Then simplify:

X = C - By over A ; A ≠ 0.

-------------------------------------

Solve for y

First subtract "Ax" from both sides:

Ax - By - Ax = C - Ax

Simplify,

By - C = Ax

Then divide both sides by B:

By/B = C/B - Ax/B ; B ≠ 0

Simplify:

Y = C-Ax / B ; B ≠ 0.
