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

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.

Answer:
B) x = 20
Step-by-step explanation:
The formula for finding the missing side of a right triangle is: a^2+b^2=c^2.
C represents the longest side of the right triangle, so if we plug in the given lengths, we can solve: 12^2 + 16^2 = x^2
Solve the exponents: 144 + 256 = x^2
Add: 400 = x^2
Find the square root: 20 = 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

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
