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

David has counters. Lisa has 5 more counters than David. Samia has 4 times as many counters as David. The total number of counters is . Write a formula for in terms of . Give your answer in its simplest form.
Answer:
if 'c' equals number of counters, the answer is 6c + 5
Step-by-step explanation:
david has 'c'
lisa has '5+c'
samia has '4c'
add all terms together: c + 5 + c + 4c = 6c + 5
The formula for the total number of counters in terms of x is T = 6x + 5
What is the algebraic expression?Algebraic expressions are mathematical statements with a minimum of two terms containing variables or numbers.
Let's start by expressing the number of counters Lisa has in terms of x. We know that Lisa has 5 more counters than David, so:
Lisa = David + 5
Lisa = x + 5
Next, we need to express the number of counters Samia has in terms of x. We know that Samia has 4 times as many counters as David, so:
Samia = 4 × David
Samia = 4x
Finally, we can express the total number of counters in terms of x by adding up the number of counters each person has:
T = David + Lisa + Samia
T = x + (x + 5) + 4x
T = 6x + 5
Therefore, the formula for the total number of counters in terms of x is T = 6x + 5.

A parabola has x-intercepts of (2, 0) and (-4, 0) and has a leading coefficient of 1. What is the equation of the parabola in standard form? *
9514 1404 393
Answer:
y = x^2 +2x -8
Step-by-step explanation:
For x-intercepts p and q, factors of the parabola's equation are (x-p) and (x-q). Since the leading coefficient is 1, those are the only factors.
y = (x -2)(x -(-4))
y = (x -2)(x +4) = x(x +4) -2(x +4) . . . . use the distributive property
y = x^2 +4x -2x -8 . . . . use the distributive property again
y = x^2 +2x -8 . . . . . . . .equation in standard form

For questions 1-4, find the distance between points A and B. Round your solutions to the nearest tenth when necessary.
Answer:
1. AB= 8.94,
2. AB= 7.28
3. AB= 16.4
4. AB= 19.21
Step-by-step explanation:
This is fun! Well you have to find the (1,4) (or point e) point and count the distance to the other points point a and point b.
4 units from a to e and 8 b to e
a² + b² = c²
8² + 4² = c²
64 +16 = c
√80 = √c²
8.94 = c
It dose not matter which units you plug in for a and b but c has to be the long side of the triangle/ hypotonuse.
Follow the same steps for the rest of the problems.

Answer:
tan=5,5
sin=0,98
Sry when Its wrong
Answer:
sin• = √13/7
tan•= -√13/4
Step-by-step explanation:
sin2•+ cos2• = 1
sin• = √1-cos2•
sin•= √1-(-4/7)2
sin•= √1-16/49
sin•= √ 49-16/49
sin•= √ 13/ 49
sin•= √13/7
tan• = sin•\cos•
= √13/7/-4/7
= -√13/4

4x + 9y = 24
X + y = 10
Help ASAP
Answer:
14
Step-by-step explanation:
Answer:
(x, y) = (-16/5, 13[tex]\frac{1}{5}[/tex])
Step-by-step explanation:
4x + 9y = 24
x + y = 10 $\Rightarrow$ x = 10 - y
Substituting the value of x (second equation) into the first equation, we get:
4 * (10 - y) + 9y = 24
40 - 4y + 9y = 24
5y = -16
y = -16/5.
So, x = 10 - (-16/5) = 10 + 3[tex]\frac{1}{5}[/tex] = 13[tex]\frac{1}{5}[/tex]

A company rents out 14 food booths and 26 game booths at the county fair. The fee for a food booth is $175 plus $8 per day. The fee for a game booth is $65 plus $7 per day. The fair lasts for d days, and all the booths are rented for the entire time. Enter a simplified expression for the amount, in dollars, that the company is paid.
The expression is ________
Answer:
$4140 + $294d
Step-by-step explanation:
Hello,
Let's write down what we know first,
d days
14 food baths -- $175 and $8 per day
26 game booths -- $65 and $7 per day
What we want to find the amount of money paid for both food baths and game booths so after finding them individually, we need to add them up.
We already know the company rents out 14 fb and 26 gb and we know that each fb is 175 dollars and each gb is 65 dollars, so we should find out the cost of buying them. We can also write out the total cost of
14 * $175 = $2450
26 * $65 = $1690
Now lets find the per day cost,
14 * $8 * d = $112d
26 * $7 * d = $182d
With both equations added together we get,
$2450 + $112d
$1690 + $182d
Add those together and we get:
$4140 + $294d
