What is the percent of decrease from 9,000 to 4,000?
Round your answer to the nearest tenth of a percent and include a percent sign (%).
Answers
first you figure out how much decreased, which is 5,000. then take that amount and put it as a fraction with the original amount. 5,000/9,000. Also know as 5/9, which is simplified to 55.56, but it turns negative because the number is decreasing.
well, 9000 - 4000 = 5000. If we take 9000 to be the 100%, how much in percent is 5000 off of it?
\(\begin{array}{ccll} amount&\%\\ \cline{1-2} 9000&100\\ 5000&x \end{array}\implies \cfrac{9000}{5000}=\cfrac{100}{x}\implies \cfrac{9}{5}=\cfrac{100}{x} \\\\\\ 9x=500\implies x=\cfrac{500}{9}\implies x=55.\overline{555}\implies \stackrel{\textit{rounded up}}{x\approx 55.6}\)

PLEASE HELP!!
Answers
Answer:
\(f + e + d = 360^o\)
Step-by-step explanation:
The question is incomplete, as what is required is not stated and the triangle is not given.
So, I will solve generally.
The proof is as follows (see attachment for triangle)
From the attachment, we have:
\(a + f = 180\)
\(b + e = 180\)
\(c + d = 180\)
Make f, e and d the subject
\(f = 180 - a\)
\(e = 180 - b\)
\(d = 180 - c\)
Add up the equations
\(f + e + d = 180 -a + 180 - b + 180- c\)
Collect like terms
\(f + e + d = 180 + 180+ 180-a- b - c\)
\(f + e + d = 540-a- b - c\)
We have:
\(f + e + d = 540-(a+ b + c)\)
\(a + b + c \to 180\) --- angles in a triangle
So, we have:
\(f + e + d = 540-180\)
\(f + e + d = 360^o\) --- proved

Answers
Answer:
2.05 secs
Step-by-step explanation:
we will use quadratic formula to work out the time t.
t = ((-b ± √(b² - 4ac)) ÷ 2a)
where a is the value of the first coefficient, b is value of the second and c is value of the constant.
h = -9t² + 15t + 7
we need water level, so h = 0.
-9t² + 15t + 7 = 0
a = -9, b = 15, c = 7.
t = ((-b ± √(b² - 4ac)) ÷ 2a)
= ((-(15) ± √((15)² - 4(-9)(7))) ÷ 2(-9))
= ((-15 ± √(225 - -252)) ÷ -18)
= ((-15 ± √(225 + 252)) ÷ -18)
= ((-15 ± √(477)) ÷ -18)
= -0.380 or 2.05
t is time, so it has to be positive.
t = 2.05 seconds to nearest one hundredth

Answers
DFS can be used because the graph is directed and all of the edge weights are positive.
What is Algorithms?
An algorithm is a process used to carry out a computation or solve a problem. In either hardware-based or software-based routines, algorithms function as a detailed sequence of instructions that carry out predetermined operations sequentially. All aspects of IT employ algorithms extensively.
Steps can be taken. There may be a path from v to z* but not from z* to v or different from each with different weights, so we just need to apply DFS, dijkstras twice, starting with vertex v, to find the path length until z*. Then we need to add the path weights.
The problem is clear in that we need to find path weight from v to z* and z* to v. There may be more than one path that leads from v to z*, thus we must locate them all and store some of them because each loop will require a time complexity of O(V+E).
where, in the given graph, E stands for edges and V for vertex. When a graph is complete, meaning there is a path connecting every vertex to every other vertex, we must execute this technique V times to determine the total number of paths. As a result, the time complexity is O(V(V+E)).
Then we must repeat the process from z* to v, but this time we must choose every path whose weights satisfy the specified condition. In the worst case, we must repeat this process (V-1) times, thus the time complexity will be the same as before. As a result, our time complexity will be O(V(V+E)) overall.
Since the graph is directed and every edge weight is positive, DFS may be used.

Given data:
Letter writing time for church = 2 hours
Follow up required for church = 1 hour
Letter writing time for labor union = 2 hours
Follow up required for labor union = 3 hour
Funds from church = $ 100
Funds from union = $ 200

Write and solve a proposition that the teacher can use to estimate how many students in the whole school would choose the aquarium.
Answers
Answer:
Let's assume that the total number of students in the school is "x". We can create a proportion to estimate how many students would choose the aquarium based on the given information:
Number of students who chose aquarium / Total number of students in the school = Percentage of students who chose aquarium / 100
We can plug in the values we know:
80 / x = p / 100
where "p" is the percentage of students who would choose the aquarium if the entire school were surveyed.
We can solve for "x" by cross-multiplying and simplifying:
8000 = px
x = 8000 / p
Now, we need to estimate the value of "p". We can do this by finding the average percentage of students who chose the aquarium, science center, planetarium, and farm:
(80 + 60 + 30 + 40) / x = (210 / x) = Average percentage of students who chose an attraction
This tells us that, on average, 210 out of every "x" students would choose one of the attractions. We can estimate that a similar percentage of the entire school would choose the aquarium:
p / 100 = 80 / 210
p = 38.1
So, we can estimate that approximately 38.1% of the students in the whole school would choose the aquarium. To find the estimated number of students who would choose the aquarium, we can plug in this value for "p" in our original proportion:
80 / x = 38.1 / 100
Cross-multiplying and solving for "x", we get:
x = 209.71
Rounding to the nearest whole number, we can estimate that approximately 210 students in the whole school would choose the aquarium.
Step-by-step explanation:
Answer:
The teacher surveyed a total of:
80 + 60 + 30 + 40 = 210 students.
If we assume that the sample of 210 students surveyed is representative of the entire population of 1000 students at Lake Middle School, we can use the relative frequency of students choosing the aquarium in the sample to estimate the number of students in the whole school who would choose the aquarium.
The relative frequency of students choosing the aquarium in the sample is:
80/210 = 0.38
This means that approximately 38% of the students in the sample chose the aquarium.
To estimate the number of students in the whole school who would choose the aquarium, we can multiply the relative frequency by the total number of students at the school:
0.38 x 1000 = 380
Therefore, the teacher can estimate that approximately 380 students out of 1000 at Lake Middle School would choose the aquarium for a field trip.

The paycheck of the salesperson at the clothing store for two weeks will amount to c. $890.
How is the paycheck calculated?The paycheck can be computed by working out the base salary, overtime pay if any, and the sales commission separately and adding up these.
Some deductions (withholding taxes and insurance) are made to the gross pay to arrive at the paycheck, which is known as the net pay.
Data and Calculations:Base salary = $10.00 per hour
Overtime pay = 1.5 of the base salary per hour
Work week = 40 hours
Commission on total sales = 3%
Sales for a month = $3,000
Commission on $3,000 sales = $900 ($3,000 x 3%)
Base salary for two weeks = $800 ($10 x 40 x 2)
Paycheck = $890 ($800 + $900)
Thus, the paycheck of the salesperson at the clothing store for two weeks will amount to c. $890.

A cardboard box manufacturing company is building boxes with length represented by x + 1 width by 5-x and height by x-1
Answers
The volume of the cardboard box with given dimensions changes at the fastest average rate over the interval of option c. [1,5].
Length of the cardboard box = x + 1
Width of the cardboard box = 5 - x
Height of the cardboard box = x - 1
Volume of the box V (x) = length × width × height
Substitute the values we have,
V(x) = (x+1)(5-x)(x-1)
Expanding this expression gives,
V(x) = -x³ + 5x² + x - 5
To know where Volume is changing at the fastest average rate,
Find the maximum value of the absolute value of the derivative of V(x) over each of the given intervals.
Taking the derivative of V(x), we get,
V'(x) = -3x²+ 10x + 1
Taking the absolute value of this expression, we get,
|V'(x)| = 3x² - 10x - 1
Now, we can calculate the maximum value of |V'(x)| over each interval,
At [1,2]
|V'(1)| = 8
|V'(2)| = 9
[1,3.5]
|V'(1)| = 8
|V'(3.5)| = 0.75
[1,5]
|V'(1)| = 1
|V'(5)| = 24
[0,3.5]
|V'(0)| = 1
|V'(3.5)| = 0.75

Kamryn plans to borrow $13,250.00 with a simple interest rate loan. Determine the amount of interest Kamryn will save if she is able to raise her credit score from 665 to 680.
Answers
Kamryn would save $159.99 in interest by raising her credit score from 665 to 680 when borrowing $13,250.00 with a simple interest rate loan.
To determine the amount of interest Kamryn will save by raising her credit score from 665 to 680, we need to compare the interest rates associated with each credit score range.
According to the given information, a credit score of 665 falls within the range of 580-669, where the corresponding simple interest rate is 10.358%.
Let's calculate the interest Kamryn would pay on a loan of $13,250.00 at an interest rate of 10.358%.
Interest = Principal * Rate
= $13,250.00 * 0.10358
≈ $1,370.56
Therefore, if Kamryn were to borrow $13,250.00 with a credit score of 665, she would pay approximately $1,370.56 in interest.
Now, let's consider the scenario where Kamryn raises her credit score to 680. A credit score of 680 falls within the range of 670-739, where the corresponding simple interest rate is 9.132%.
Calculating the interest with a credit score of 680:
Interest = Principal * Rate
= $13,250.00 * 0.09132
≈ $1,210.57
Thus, if Kamryn were able to raise her credit score from 665 to 680, she would save approximately $1,370.56 - $1,210.57 = $159.99 in interest.
Therefore, Kamryn would save approximately $159.99 in interest by raising her credit score from 665 to 680 when borrowing $13,250.00 with a simple interest rate loan.

Six (6) confidence intervals or hypothesis tests would need to be done to make significant statements for each pair-wise comparison.
In an ANOVA F test, the null hypothesis is that the means of all the treatments are equal, and the alternative hypothesis is that at least two of the means are different. If the null hypothesis is rejected at the 5% significance level, this means that the differences between the means are statistically significant and the treatments can be considered different.

Using an algebraic equation to represent the word problem, the smallest integer is 1
Word ProblemThis is a way of representing mathematical problems with words. To solve this, we have to use algebraic equations or expressions.
Let the integers be represented as
xx + 2x + 4We can write an equation from the word problem given as
7 × (x + 2) = 15 + [x + (x + 4)]
7x + 14 = 15 + x + x + 4
7x + 14 = 15 + 2x + 4
collect like terms
7x - 2x = 15 - 14 + 4
5x = 5
Divide both sides by coefficient of x
5x / 5 = 5 / 5
x = 1
The smallest integer is 1
