The absolute difference is estimated as $2.9 million and relative difference is calculated as 26%.
What is defined as the absolute change?The absolute change refers to the actual increase or decrease from the a reference value to a new value:
absolute difference = new value - reference value
In the given question, the reference value is given as $10.8 million.
The new value is $13.7 million.
absolute difference = 13.7 - 10.8
absolute difference = 2.9
Thus, the absolute value if estimated as $2.9 million.
What is defined as the relative difference?The absolute difference is described as a fraction of a reference value by the relative difference:
The formula for calculating the relative difference is;
relative difference = (new value - reference value)/reference value
relative difference = absolute difference/reference value
Substituting the values;
relative difference = 2.9/10.8
relative difference = 0.26
relative difference% = 0.26×100%
relative difference = 26%.
Thus the relative difference is estimated as 26%.

The base of a 15 foot ladder is 6 feet from a building, if the ladder reaches the flat roof, How tall is the building?
Answer:
13.7 feet
Step-by-step explanation:
The ladder and the building will form a right triangle with the ladder's length is hypotenuse
so if a is the height of the building
c^2 = a^2 + b^2
(15)^2 = a^2 + (6)^2
225 = a^2 + 36
a^2 = 225 - 36 = 189
a = √(189 = 13.7

Two cars got an oil change at the same auto shop. The shop charges customers for each quart of oil plus a flat fee for labor. The oil change for one car required 5 quarts of oil and cost $21.90. The oil change for the other car required 7 quarts of oil and cost $25.40. How much is the labor fee and how much is each quart of oil?
Answer:
Step-by-step explanation:
Let x = the fee and let y = the cost per quart of oil
x + 5y = 22.45
x + 7y = 25.45 Multiply this equation by (-1) and add it to the 1st equation
-x -7y = -25.45
x + 5y = 22.45
-2y = -3
y = $1.50 /quart
x + 5(1.50) = 22.45
x + 7.50 = 22.45
x = $14.95 is the basic fee

Use symmetry to evaluate the following integral.
[tex]\int\limits^4_{-4} {\frac{x^3+3x}{x^4+5} } \, dx[/tex]
The integrand is odd.
[tex]f(x) = \dfrac{x^3 + 4x}{x^4 + 5} \implies f(-x) = \dfrac{(-x)^3 + 4(-x)}{(-x)^4 + 5} = \dfrac{-x^3-4}{x^4+5} = -f(x)[/tex]
The integral of an odd function over a symmetric interval is zero, so
[tex]\displaystyle \int_{-4}^4 \frac{x^3+3x}{x^4+5} \, dx = 0[/tex]
This is because
[tex]\displaystyle \int_{-a}^a f(x) \, dx = \int_{-a}^0 f(x) \, dx + \int_0^a f(x) \, dx \\\\ ~~~~ = -\int_0^{-a} f(x) \, dx + \int_0^a f(x) \, dx \\\\ ~~~~ = \int_0^{-a} f(-x) \, dx + \int_0^a f(x) \, dx \\\\ ~~~~ = -\int_0^a f(x) \, dx + \int_0^a f(x) \, dx = 0[/tex]
where we substitute [tex]x\mapsto-x[/tex] in the second-to-last equality.

Answer:
n = 3.8
Step-by-step explanation:
First, we would distribute 0.3 with n and 1.5.
0.3(n - 5) = 0.4 - 0.2n → 0.3n - 1.5 = 0.4 - 0.2n
Next, we can move the number with the variable to one side.
0.2n + 0.3n - 1.5 = 0.4 - 0.2n + 0.2n → 0.2n + 0.3n - 1.5 = 0.4
(Because we added 0.2n to the negative 0.2n on the right side, it cancels it out)
We can also move 1.5 to the right side of the equation as well.
0.2n + 0.3n - 1.5 + 1.5 = 0.4 + 1.5 → 0.2n + 0.3n = 0.4 + 1.5
Then, we combine like terms
0.2n + 0.3n = 0.5n & 0.4 + 1.5 = 1.9 → 0.5n = 1.9
Finally, we divide both sides by 0.5.

A well know Statistical Institution claims that the average College tuition for a law degree costs at least thirty five thousand dollars. Analyzing a sample of fifty law schools in the vicinity of the study we found the sample had a mean tuition of $33,450 with a population standard deviation of $5,978 per year. At 2% level of significance test the Institution's claim.
Step-by-step explanation:
Below are the null and alternative Hypothesis,
Null Hypothesis, H0: μ = 35000
Alternative Hypothesis, Ha: μ < 35000
Test statistic,
z = (xbar - mu)/(sigma/sqrt(n))
z = (33450 - 35000)/(5978/sqrt(50))
z = -1.83
P-value Approach
P-value = 0.0336
As P-value >= 0.02, fail to reject null hypothesis.
There is not sufficient evidence to conclude that the average College tuition for a law degree costs at least thirty five thousand dollars.
Dawn bought 3 video games and 9 DVDs for $75. Jerry bought
5 video games and 10 DVDs for $25 more than Dawn. How
much did each DVD cost?
Answer:
$5
Step-by-step explanation:
We can solve this using a system of linear equations. The equations are written like this:
3v + 9d = 75
5v + 10d = 100 (25 more than Dawn's total is 100)
V represents video games and d represents DVDs.
Let's isolate a variable, I'm going to isolate v in the first equation:
3v = -9d + 75
v = -3d + 25
Now that we isolated v we can plug it in to the second equation:
5(-3d + 25) + 10d = 100
-15d + 125 + 10d = 100
-5d + 125 = 100
-5d = -25
d = 5
Therefore, each DVD cost $5.
Check:
3v + 9(5) = 75
3v + 45 = 75
3v = 30
v = 10
5(10) + 10(5) = 100
50 + 50 = 100
100 = 100

What is the correct evaluation of x2 - x + y2 when x is equal to 5 and y is equal to -2?
the value for the expression x² - x + y² for x = 5 and y = - 2 will be 24.
We are given an expression:
x² - x + y²
We need to find the value of the expression for x = 5 and y = - 2.
Now, substituting the values of x and y in the expression that is given to us, we get that:
x² - x + y²
( 5 )² - ( 5 ) + ( - 2 )²
Solving the squares of the numbers, we get that:
25 - 5 + 4
Simplifying to get the value of the expression, we get that:
= 24
Therefore, the value for the expression x² - x + y² for x = 5 and y = - 2 will be 24.

A shipping container will be used to transport several 120-kilogram crates across the
country by rail. The greatest weight that can be loaded into the container is 25500
kilograms. Other shipments weighing 14500 kilograms have already been loaded into
the container. What is the greatest number of 120-kilogram crates that can be loaded
into the shipping container?
Answer: 91 crate
Step-by-step explanation:
weight preloaded=
14500
weight per crate=
120
weight capacity=
25500
Method 1 (Unwinding):
weight of all crates=
weight capacity−weight preloaded
=

=
11000
number of crates=
weight per crate

=
91.666666...
Technically, 91.666666... is the greatest number of crates that can be loaded into the shipping container. But you can't load part of a crate. The true maximum is the highest whole number below 91.666666..., which is 91.
Method 2 (Algebra):
c= number of crates
The greatest weight means less than 25500 kilograms can also be loaded into the container, so we will use the \leq≤ ("less than or equal to") symbol:
120c+14500≤
25500
−14500=
−14500
\color{red}{120}c\leq
120c≤
11000

11000
Divide both sides by 120
c ≤ 91.666666...
Technically, 91.666666... is the greatest number of crates that can be loaded into the shipping container. But you can't load part of a crate. The true maximum is the highest whole number below 91.666666..., which is 91.

6. If a refrigerator has a mass of 750 kg and a volume of 600 mL, what is it's density?
Answer:
[tex] \sf \rho \: = 1.25[/tex]
Step-by-step explanation:
Density, is the substance's mass per unit of volume. The symbol most often used for density is ρ, although the Latin letter D can also be used. Mathematically, density is defined as mass divided by volume:
[tex]{\displaystyle \rho ={\frac {m}{V}}} [/tex]
where ρ is the density, m is the mass, and V is the volume.
[tex] \sf \rho = \frac{750}{600} [/tex]
[tex] \sf \rho \: = 1.25[/tex]
Therefore, density is equal to 1.25

Answer:
7:55
Step-by-step explanation:
I didn’t understand this question please help
Answer:
(a) y = 4x - 15
(b) y = (-1/4)x + 2
Step-by-step explanation:
The slope-intercept equation form for a line is
y = mx + b
Here m is the slope (rise/run) and b is the y-intercept ie the y-value at which the line crosses the y axis at x = 0. Drawing a picture helps
If two lines have the same slope, they are parallel
If another line has slope -(1/m) then it is perpendicular to the line with slope m
First convert the line equation into slope-intercept form as follows
8x - 2y = 1
Subtract 8x from both sides ==> -2y = 1- 8x
Multiply both sides by -1 ==> 2y = 8x - 1
Divide both sides by 2:
y = 4x - 1/2
Parallel line
y = 4x - 1/2
A parallel line should also have slope = 4
So it's equation will be of the form
y = 4x + b
To determine b, the y intercept, plug in values for x = 4, y =1 ad solve for b
1 = 4(4) + b ==> 1 = 16 + b ==> b = -15
So the equation of a line parallel to 8x - 2y = 1 passing through (4,1) is
y = 4x - 15 (Answer a)
Perpendicular Line
A perpendicular line to y = 4x - 1/2 should have the negative of the reciprocal of the slope
So the slope of the perpendicular line is -(1/4)
Equation is
y = -(1/4)x + b
Plug in the point values for (4, 1) to get
1 = - (1/4)(4) + b
1 = -1 + b
b = 2
So the equation of a line perpendicular to 8x - 2y = 1 passing through (4,1) is y = -(1/4)x + 2
