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.

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

Answer:

The answer is 6

Step-by-step explanation:

First,

10 x 3 ( numerator ) = 30

30 divided by 5 = 6

Answer:

The answer is 6

Step-by-step explanation:

  10 * [tex]\frac{3}{5}[/tex]

= [tex]\frac{10 * 3}{5}[/tex]

= [tex]\frac{30}{5}[/tex]

= 6

maybe try -5 since the rise/run is 5/1 and the slope is negative

The slope of the graphed line is m = -5

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

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

Step-by-step explanation:

The value without Exponent are  n x n x n x n x n x n x n.

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:

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
