Cars lose value the farther they are driven. A random sample of 11 cars for sale was taken. All 11 cars were the same make and model. A line was fit to the data to model the relationship between how far each car had been driven and its selling price.
Answer:
[tex]y=-\frac{1}{4}x+40[/tex]
Step-by-step explanation:
Given
See attachment for graph
Required
Determine the equation of the line of best fit
First, calculate the slope (m)
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
From the graph, we can have:
[tex](x_1,y_1) = (20,35)[/tex]
[tex](x_2,y_2) = (60,25)[/tex]
So, the slope is:
[tex]m = \frac{25 -35}{60 - 20}[/tex]
[tex]m = \frac{-10}{40}[/tex]
[tex]m = -\frac{1}{4}[/tex]
The equation is then calculated as:
[tex]y = m(x - x_1) + y_1[/tex]
[tex]y = -\frac{1}{4}(x - 20) + 35[/tex]
[tex]y = -\frac{1}{4}x + 5 + 35[/tex]
[tex]y=-\frac{1}{4}x+40[/tex]
Hence, the equation is: [tex]y=-\frac{1}{4}x+40[/tex]
Mary bought a desk on sale for 88.40. This price was 74% less than the original price.
What was the original price?
Answer:
p = $340
Step-by-step explanation:
Let p represent the original price. Then the amount Mary paid was (100% - 74%) of the original price: 0.26p = $88.40.
Solving for p: p = $340
Check: what is 74% of $340? $251.60. Subtracting this from $340, we get $88.40. This agrees with the problem statement.

A regular pentagon is shown. A regular pentagon has side lengths of 9.4 centimeters and a radius of 8 centimeters. What is the length of the apothem, rounded to the nearest tenth?
Answer:
6.5 cm
Step-by-step explanation:
The computation of the length of the apothem is shown below:
Given that
The side length is 9.4 centimeters
And, the radius is 8 centimeters
Now based on the above information
As per the attached figure
AB = 8 cm
BC = 9.4 ÷ 2 = 4.7 cm
Now apply the pythagoras theorem
AB^2 = BC^2 + AC^2
8^2 = 4.7^2 + AC^2
AC^2 = 41.91
AC = 6.47 cm
= 6.5 cm
Answer: D). 6.5 cm

What expression can you use to find 17 divided by 4/5?
A: 4/5 divided by 16
B: 16 divided by 5/4
C: 16 times 5/4
D: 4/5 times 16
Answer: B) 16 times 5/4
Step-by-step explanation:
16 divided by 4/5 = 20
16 x 5/4 = 20
When a whole number like 16 is divided by a fraction such as 4/5, you multiply it by the reciprocal (flipped version) of the fraction. What is the reciprocal of 4/5? It's 5/4. From there, you can solve each equation to make sure they are equivalent to check.
Cos(8x+21)=sin(-2x+51) Find the two angles represented in degrees ??? Someone help its 1am I can't do this
Answer:
45 and 135degrees
Step-by-step explanation:
Cos(8x+21)=sin(-2x+51) Find the two angles represented in degrees ??? Someone help its 1am I can't do this
In trigonometry, cosx = sin(90-x)
Hence:
Cos(8x+21) = sin(90-(8x+21))
Cos(8x+21) = sin(90-8x-21)
Cos(8x+21) = sin(-8x+69)
Substituting into the expression given, :
sin(-8x+69) = sin(-2x+51)
-8x+69 = -2x+51
-8x+2x = 51-69.
-6x = -18.
X = 18/6
X = 3
Since the angles 8x+21
Angle = 8(3)+21
Angle = 45
The angles represented in degrees are 45 and (180-45) = 135degrees
ASAP HELP. What is the solution for M?
Answer: m ≥ −5 pls give me brainliest
Step-by-step explanation: 9≥−2m+2−3
Subtract 3 from 2 to get −1.
9≥−2m−1
Swap sides so that all variable terms are on the left hand side. This changes the sign direction.
−2m−1≤9
Add 1 to both sides.
−2m≤9+1
Add 9 and 1 to get 10.
−2m≤10
Divide both sides by −2. Since −2 is negative, the inequality direction is changed.
m≥
−2
10
Divide 10 by −2 to get −5.

A 50,000 investment earns 18 percent annually. If b represents the balance and t represents the number of years
Answer: B = 50,000 * 1.18^t
Step-by-step explanation:
This requires the use of the Future Value formula.
Future value = Amount invested + ( 1 + rate) ^ number of years invested
Future value = B in this scenario.
t = number of years.
When putting in figures therefore, the formula becomes:
B = 50,000 * ( 1 + 18%) ^ t
B = 50,000 * 1.18^t

In 1978, the amount of earnings required to earn one Social Security credit was $250. Thirty-eight years later, in 2016, the amount was $1260. What was the percent increase in the amount required to earn a credit over this 38-year span?
Answer:
404%
Step-by-step explanation:
To find the percentage difference do the following: (FV - SV)/|SV| * 100
(1260 - 250)/|250| * 100 {Subtract 250 from 1260 to get 1010. The absolute value of 250 is 250.}
1010/250 * 100 {Divide 1010 by 250 to get 4.04, or 101/25.}
101/25 * 100/1 {CROSS CANCELLATION}
101 * 4 {Multiply 4 by 101 to get 404.}
404%
The percent increase in the amount required to earn a credit over 38 years is 404%.

A store sells small and large TV sets in the ratio 2:3.The total stock is 70 sets.1)How many small and large sets are in stock? 2)If the number of large sets is increased by 8 ,what is the new ratio of small to big
Answer: a) There are 28 small TV sets and 42 big TV sets
b) new Ratio of small and large TV set= 28:50
Step-by-step explanation:
Total stock of large and small TV=70
Ratio of small and large TV set=2:3
a) Total ratio=2+3=5
Small set=2/5 x 70= 28 small TV sets
Big set=3/5 x 70 = 42 big TV sets
b)f the number of large sets is increased by 8 then
Big set TV = 42 + 8=50
new Ratio of small and large TV set= 28:50

If there is an 9% tax
on a $18 football,
what is the tax
amount?
Answer: $1.62
Step-by-step explanation:
9% = 0.09
18 * 0.09 = 1.62
Answer:
1.62
Step-by-step explanation:
To find 9 percent of the number 18, we must create a proportion from which we can easily determine the value we are looking for.
First we create two simple equations with data that we know.
18 equals 100%, so we can save it as 18 = 100%
The value we are looking for can be called x
Now we know that x is 9 of the output value, so we can write it as x = 9.
So we have two simple equations:
1) 18 = 100%
2) x = 9%
When we compare these two equations, we get:
18 / x = (100%) / (9%)
Now we just have to solve the simple equation.
We calculate 9 percent of 18:
18 / x = 100/9
(18 / x) * x = (100/9) * x
18 = 11.111111111111 * x
18 / 11.111111111111 = x
1.62 = x
x = 1.62
Solution:
9 percent of 18 = 1.62
