Step-by-step explanation:
n is an integer and -2
Write down the possible values of n,
from smallest to largest.
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 }

If f(x)=4x-3,what is f(x)^-1?
Answer:
Choice A
Step-by-step explanation:
I like to solve this by reversing the locations of the x and y, and then isolating y again.
y=4x-3
x=4y-3
x+3=4y
y=(x+3)/4

Given: ∆ABC, m∠C = 90° CB = 8, m∠B = 38º Find the area of a circumscribed circle. Find the area of the inscribed circle.
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].

Compute $121_3+2122_3-1200_3-2111_3$. Express your answer in base 3.
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
SOMEONE PLEASE HELP ASAP! Normal distribution models what type of variable? A.discrete random variable B.random variable C.discrete continuous variable D.random continuous variable
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.

In numb3rs, they use math to solve crimes. One of the ways they use Math is to reveal patterns. What is the pattern in this sequence? What would be the first and last numbers be? (6, 14, 30, 62, 126)
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

Which represents continuous data? A) The number of times you flip a coin B) The number of students in a classroom C) The number of chocolate candies in a box D) The price of fish per pound
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

Use the method of substitution to solve the system of equations. please show your work! y=534x y=74.80x+1,419 Thank you so much! If you could also solve it graphically that would be best but if not thats okay!
Answer:
( 3, 1650 ), Where x = 3, and y = 1650 -
Approximately
Step-by-step explanation:
Take a look at the procedure below;
[tex]y = 534x,\\y = 74.80x + 1,419\\\\y = 534x,\\y - 74.8x = 1,419\\\\( 534x ) - 74.8x = 1,419\\459.2x = 1,419\\x = ( About ) 3\\\\y = 534 * ( x ),\\y = 534 * ( 3.1 ),\\y = ( About ) 1650[/tex]
We first converted the second equation into standard form, by subtracting 74.8x on either side. Afterwards we substituted 534x in replacement of y in this second equation, and solved for x. Knowing the value of x, it was substituted back into the first equation to solve for the value of y. Hence, the resulting solution is ( 3, 1650 ) - approximately.

What are Congruent Triangles?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

Do 5 A,B for 10 points.
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.

In the inverse variation function, what happens to the output when the
function's input value is multiplied by 4?
O A. The output is divided by 2.
OB. The output is multiplied by 4
O C. The output is negated
O D. The output is divided by 4
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.
Therefore, the correct option is D.
Which equation represents the graphed function?
0 -3x + 2 = y
0 -2/3x+2=y
O 3/2x-3=y
O 2x - 3 = y
Answer:
3/2x-3 =y
Step-by-step explanation:
when x = 0 the equation should equal -3 because the y intercept is (0,-3) which narrows down to the last two.
The x-intercept is (2,0) input these values into the equation and the third option gives these values.
[tex]\frac{3}{2}[/tex](2) -3 = y ,
3-3=y
y=0 Therefore the third option is the answer
