2. The following list of prices is for a used original radio for a 1955 Thunderbird. The prices vary
depending on the condition of the radio.
$210, $210, $320, $200, $300, $10, $340, $300, $245, $325, $700, $250, $240, $200
a. Find the mean of the radio prices. Round to the nearest cent.
Answer: $275
Step-by-step explanation:
The mean of the radio price is $275 or 27500 cents
Given,
Price of used original radio for a 1955 Thunderbird:
$210, $210, $320, $200, $300, $10, $340, $300, $245, $325, $700, $250, $240, $200
We need to find the mean of these prices.
And round to nearest cent.
What is the mean of a set of values?The mean is the average of all the given sets of values.
Example:
1,2,3,4
Mean = (1+2+3+4) / 4 = 10/4 = 2.5
Find the sum
$210, $210, $320, $200, $300, $10, $340, $300, $245, $325, $700, $250, $240, $200
Sum=(210+210+320+200+300+10+340+300+245+325+700+250+240+200)
Sum = 3850
Find the number of prices.
= 14 prices
Find the mean.
= 3850 / 14
= 275
The mean radio price is $275.
Converting into cents.
$1 = 100 cents
$275 = 27500 cents
Thus the mean of the radio price is $275 or 27500 cents

15
-10
-5
5
10
--5
-10
OA. -5
OB.

OD. 5
maybe try -5 since the rise/run is 5/1 and the slope is negative
The slope of the graphed line is m = -5
What is an Equation of a line?The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation of line be represented as A
Now , the value of A is
Let the first point be P ( 0 , 2 )
Let the second point be Q ( 2 , -8 )
Now , the slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Substituting the values in the equation , we get
Slope m = ( 2 - ( -8 ) ) / ( 0 - 2 )
m = 10 / -2
m = -5
Hence , the slope is m = -5

Et of y=x2-4 and + y + 2 = 0?
The equation y = x2 – 4 + y + 2 = 0 can be solved by completing the square.
What is equation?An equation is a mathematical statement that to express our equal. Is consist of two expression separated by an equal sign and can contain numbers, variables and operators. Equation get be used to solve problems make prediction and describe relationship between different quantities. Equation can be can also be used to represent physical laws and other phenomena.
First, subtract y from both sides of the equation to get x2 - 4 + 2 = y. Then, subtract 2 from both sides of the equation to get x2 - 6 = y. Finally, add 9/4 to both sides of the equation to get (x - 3/2)2 = 9/4 + y.
This equation can be solved by taking the square root of both sides to get x - 3/2 = ±√(9/4 + y). Finally, add 3/2 to both sides of the equation to get x = 3/2 ±√(9/4 + y).

3(x-3) = -2x + 31 what is the value of x?
Answer:
x= 8
Step-by-step explanation:
1. Expand.
3x-9=-2x+31
2. Add 9 to both sides.
3x=-2x+31+9
3. Simplify -2x+31+9 to -2x+40.
3x=-2x+40
4. Add 2x to both sides.
3x+2x=40
5. Simplify 3x+2x+5x.
5x=40
6. Divide both sides by 5.
x = 40/5
7. Simplify 40/5 to 8.
x=8

write n^5 x n^2 without exponents
The value without Exponent are n x n x n x n x n x n x n.
What are Exponents and Powers?Exponents and powers can be used to represent extremely big or extremely small numbers in a more straightforward fashion.
For example, if we have to show 3 x 3 x 3 x 3 in a simple way, then we can write it as [tex]3^4[/tex], where 4 is the exponent and 3 is the base.
Given:
[tex]n^5[/tex] x n²
Using the Property of Exponents and power
[tex]a^m[/tex] x [tex]a^n = a^{m+n[/tex]
So, [tex]n^5[/tex] x n²
= [tex]n^{5+2}[/tex]
= [tex]n^7[/tex]
= n x n x n x n x n x n x n
Hence, the exponents is n x n x n x n x n x n x n.
