Find the mean, median, and mode of the data set. Show your work. (10 points)
Step-by-step explanation:
median -> $24.710+$25.180=$49.89
$49.98÷2=$24.945
mode -> $25.520 and $24.710
mean -> $24.640+$26.740+$23.620+$25.520+$24.710+$25.180+$25.520+$24.750+$24.710+$23.860= $249.25

On a car trip , the number of miles driven , m , is proportional to the number of gallons of gas used , g , as shown in the table
Answer:
m = 32g
Step-by-step explanation:
The proportion between m and g can be written ...
m = kg
where k is the constant of proportionality.
__
We can find its value by dividing by g:
k = m/g
Using any pair of corresponding values from the table, we find ...
k = 64/2 = 32
The relationship between m and g can be expressed by the equation ...
m = 32g

will pay $20 each month until the TV is paid off. Which equation represents the
relationship between x, the number of payments James has made, and y, the
total amount that James has paid the store?
-
A: y-40x+20
B: y-20
C: y - 20x-40
D: y-20x+40
Answer:
C y = 20x +40

Given the functions below, find f(2)-g(-7).
Will give brainliest :))
Answer:
49
There u go :)
Answer:
Given the functions below, f(2) - g(-7) is -34.
Step-by-step explanation:
f(2) - g(-7)
First solve f(2).
f(x) = -|3 - 8x|
Substitute variable.
f(2) = -|3 - 8(2)|
Multiply.
f(2) = -|3 - 16|
Subtract 16 from 3.
f(2) = -|-13|
Apply absolute value.
f(2) = -13
Now solve g(-7).
g(x) = x² + 4x
Substitute variable.
g(-7) = (-7)² + 4(-7)
Raise -7 to the second power.
g(-7) = 49 + 4(-7)
Multiply 4 and -7.
g(-7) = 49 - 28
Subtract 28 from 49.
g(-7) = 21
Now with those values, lets go back to our original equation.
f(2) - g(-7)
Substitute known values.
-13 - 21
Subtract 21 from -13.
-34.

Write an equation for the line that is parallel to the given line and that passes though the given point
y = 4x -21 (again cool name btw) :)
y=4x-3 has slope = to the coefficient of the x term = 4
all parallel lines have the same slope.
y=4x + b, where b can be any real number, so just plug in the point (4,-5) into the general equation
y=4x+b = -5 = 4(4) + b
-5 = 16 + b
-21 = b
b = -21 = the y intercept, so the equation is
y=4x -21

Answer:
[tex]1609.1 m^{3}[/tex]
Step-by-step explanation:
The area of a triangle is 1/2 base * height.
The base of one side is 13, and the height is 30.
30 * 13 = 390
390 / 2 = 195
Now, there are six of these triangle faces, so multiply that number by six.
195 * 6 = 1170
Now, just add the area of the base:
1170 + 439.1 = 1609.1
The price of a pack of kitchen rolls is reduced by
1/6
The new price is £1.20
Work out the original price.
Answer: 1.44
Step-by-step explanation: 1.20 Is the remaining 5/6 which is 83.3%
Calculate for 100% to get actual amount
If 83.3% = 1.20
1% = 1.20/83.3
100% = 1.20/83.3 ×100/1
The original price is equal to £7.2
What are the cost price and selling price?1. Cost price = Selling price − profit ( when selling price and profit are given )
2. Cost price = Selling price + loss ( when selling price and loss are given )
Given here: New price =£ 1.20
let the original price be x then we have
x/6 = 1.20
x=£7.2
Hence, The original price is £7.2

find the angle between unit vector I and a=√3i+j
Recall that for two vectors x and y,
x • y = ||x|| ||y|| cos(θ)
where θ is the angle between them.
We have
i • (√3 i + j) = √3
||i|| = 1
||√3 i + j|| = √((√3)² + 1²) = √4 = 2
Solve for θ :
√3 = 2 cos(θ)
cos(θ) = √3/2
θ = arccos(√3/2) = π/6
(Note that we assume θ is the acute angle between the vectors.)

The function f(x) = 2* and g (x) = f(x) + k. If k = 2, what can be concluded about the graph of
g (x)?
Translations are transformations that change the position of the graph of a function. The general shape of the graph of a function is moved up, down, to the right or to the left. The translations are considered rigid transformations.
Suppose that k> 0
To graph y = f (x) + k, move the graph of k units up.
To graph y = f (x) -k, move the graph of k units down.
We have then:
f (x) = 2 ^ x
g (x) = f (x) + k
if k = 2
then,
the graph of g (x) is shifted vertically 2 units up
Answer:
the graph of g (x) is shifted vertically 2 units up

The tangent or tanθ function of trigonometry is the ratio of its perpendicular to its base in a right triangle. The total height of the sky scrapper is 118.25 meters.
What is Tangent (Tanθ)?The tangent or tanθ function of trigonometry is the ratio of its perpendicular to its base in a right triangle. it is given as,
[tex]\rm Tangent(\theta) = \dfrac{Perpendicular}{Base}[/tex]
where,
θ is the angle,
Perpendicular is the side of the triangle opposite to the angle θ,
The base is the adjacent smaller side of the angle θ.
Since the horizontal distance between Hannah's eyes and the sky scrapper is 194 meters while the angle between the eye and the top of the sky scrapper is 31°. Therefore, the vertical height of the sky scrapper from the height of Hannah's eye level, using the tangent function can be written as,
[tex]\rm Tangent(\theta) = \dfrac{Perpendicular}{Base}\\\\\\tan(31^o) = \dfrac{\text{Height of sky scrapper from eye level}}{194\ meters}\\\\\\\text{Height of sky scrapper from eye level} = 116.567\ meters[/tex]
Since the height of the eye level is 1.68 meters from the ground, therefore, the total height of the sky scrapper can be written as,
[tex]\rm \text{Total height of sky scrapper from ground}\\\\=(\text{Height of sky scrapper from eye level}) + 1.68\ meters\\\\= 116.567 + 1.68\\\\= 118.25\ meters[/tex]
Hence, the total height of the sky scrapper is 118.25 meters.
