Answer:
The answer is True:
Let's solve your equation step-by-step.
1/n−1 = 4/15
Step 1: Cross-multiply.
1/n−1 = 41/ 5
(1)*(15)=4*(n−1)
15=4n−4
Step 2: Flip the equation.
4n−4=15
Step 3: Add 4 to both sides.
4n−4+4=15+4
4n=19
Step 4: Divide both sides by 4.
4n/4=19/4
n=19/4
simplify:
19/4 = 4.75
4.75 in decimal for is equal to 4 3/4

At a homecoming game, there are 630 students and 1080 alumni in attendance. Express the
ratio of students to alumni as a fraction in simplest form. Explain its meaning,
Answers
Answer:
7/12
There are 7 students for every 12 alumni
Step-by-step explanation:
So, the ratio of students to alumni is 630/1080. This means there are 630 students for every 1080 alumni.
However, we can simplify this. If you treat this like a fraction and simplify, it will be much easier. Both numerator and denominator can be divided by 90, so that's what we'll do. 630/90 is 7. 1080/90 is 12.
Therefore, the correct answer is 7/12!

Answers
Answer:
lines a and b are parallel. The slopes are -1/3
None of the lines are perpendicular to each other.
Step-by-step explanation:
To figure out if any of the lines are parallel or perpendicular to each other, you have to find the slopes of each line. To find the slope look at the graph find the rise over run for all of the lines:
line a: This line goes down one every time it goes over 3, which can be represented by -1/3
line b: This lines goes down one every time it goes over 3, which can also be written as -1/3
line c: This line goes up 5 every time it goes over 2, which makes the slope 5/2
When two lines are parallel, they have the same slope. Line a and line b have the same slope, so they are parallel.
When two lines are perpendicular, their slopes are negative reciprocals of each other. Since none of the slopes are a negative reciprocal of another slope, we have no perpendicular lines.
Hope this helps :)

Answers
Answer:
About $804.70
Step-by-step explanation:
So, for this you will need the formula: "A = B(1 + r)^t" It is + 1 since it is an increase.
B = Initial Value
r = rate
t = time
A = B(1 + r)^t
A = 523(1 + 0.09)^5
A = 523(1.09)^5
A = 523(1.5386239549)
A = 804.700328413
A ≈ 804.70

determine if the sequence is arithmetic. if it is find the common difference. -34,-64,-94,-124
Answers
Generally speaking, arithmetic sequences have the form:
an=a1+(n-1)*d
Where:
an=the nth term in the sequence
a1=the 1st term in the sequence
n=the number of terms in the sequence
d=the difference between consecutive terms (i.e. d=an-an-1=a2-a1=a3-a2, etc.)
The SUM of the terms of an arithmetic sequence, notated Sn, is given by:
Sn=[n/2]*[2a1+(n-1)*d]
So if n=8 then:
a8=a1+7d=63
And if there are 94 terms in the sequence then:
S94=[94/2]*[2a1+93d]=47*(2a1+93d)=94a1+4371d=1000
So this is a system of equations where:
{ a1 + 7d = 63 (Multiply this first equation by -94 on both sides and add to second equation)
{ 94a1 + 4371d = 1000
-94a1 - 658d = -5922 (Add this new equation to second equation)
Therefore:
3713d = -4922
So:
d = -4922/3713
Answer: arithmetic / -30
Step-by-step explanation: This is an arithmetic sequence.
The reason I know that is because the same number is being
added each time to get the next term in the sequence.
In this case, we are adding -30 each time to reach the next term.
So the common difference is -30.

A tower is 234 meters tall. Jaylon is looking up at the top of the tower and thinking it would be cool to string a zip line from the top of the tower to a platform that is 1.9 meters high. If the angle formed between the zip line and tower would be 76 degrees how many meters of the line is neded?
Answers
Answer:
A length of 959.401 meters is needed for the zip line is needed to string it from the top of the tower to the platform.
Step-by-step explanation:
The geometrical representation of the statement is summarized in the figure below attached. The length of the line is represented by hypotenuse of the right triangle, whose value is calculated by the help of trigonometrical relations:
[tex]\cos \alpha = \frac{h}{r}[/tex] (1)
Where:
[tex]\alpha[/tex] - Angle formed between the zip line and the tower, measured in sexagesimal degrees.
[tex]h[/tex] - Vertical distance between the tower and the platform, measured in meters.
[tex]r[/tex] - Length of the zip line, measured in meters.
If we know that [tex]\alpha = 76^{\circ}[/tex] and [tex]h = 232.1\,m[/tex], then the length of the zip line is:
[tex]r = \frac{h}{\cos \alpha}[/tex]
[tex]r = \frac{232.1\,m}{\cos 76^{\circ}}[/tex]
[tex]r = 959.401\,m[/tex]
A length of 959.401 meters is needed for the zip line is needed to string it from the top of the tower to the platform.

A ladder is leaning against a house. The distance to the house's edge from the bottom step is 3 ft. and the distance from the edge to the top step is 4 ft. What is the slant of the ladder?
Answers
Answer:
The slant of the ladder is 5 ft
Step-by-step explanation:
Look at the attached figure to understand this situation
∵ a represents the distance from the edge to the top step
∵ The distance from the edge to the top step is 4 ft
∴ a = 4 ft
∵ b represents the distance to the house's edge from the bottom step
∵ The distance to the house's edge from the bottom step is 3 ft
∴ b = 3 ft
∵ c represents the slant of the ladder
∴ We need to find c
→ By using the Pythagoras Theorem
∵ c = [tex]\sqrt{a^{2}+b^{2}}[/tex]
∴ c = [tex]\sqrt{(4)^{2}+(3)^{2}}=\sqrt{16+9}=\sqrt{25}[/tex]
∵ [tex]\sqrt{25}[/tex] = 5
∴ c = 5 ft
∴ The slant of the ladder is 5 ft

The number of responses to a survey are shown in the Pareto chart. The survey asked 1052 adults how they would grade the quality of their public schools. Each person gave one response,
Find each probability
(a) Randomly selecting a person from the sample who did not give the public schools an A
(1) Randomly selecting a person from the sample who gave the public schools a grade better than a D
(c) Randomly selecting a person from the sample who gave the public schools a Dor an F
(d) Randomly selecting a person from the sample who gave the public schools an A or B
(a) The probability that a randomly selected person did not give the public schools an Als
(Round to three decimal places as needed)
Answers
Answer: (a) P(no A) = 0.935
(b) P(A and B and C) = 0.0005
(c) P(D or F) = 0.379
(d) P(A or B) = 0.31
Step-by-step explanation: Pareto Chart demonstrates a relationship between two quantities, in a way that a relative change in one results in a change in the other.
The Pareto chart below shows the number of people and which category they qualified each public school.
(a) The probability of a person not giving an A is the difference between total probability (1) and probability of giving an A:
P(no A) = [tex]1-\frac{68}{1052}[/tex]
P(no A) = 1 - 0.065
P(no A) = 0.935
b) Probability of a grade better than D, is the product of the probabilities of an A, an B and an C:
P(A and B and C) = [tex](\frac{68}{1052})(\frac{258}{1052})(\frac{327}{1052})[/tex]
P(A and B and C) = [tex]\frac{5736888}{1164252608}[/tex]
P(A and B and C) = 0.0005
c) Probability of an D or an F is the sum of probabilities of an D and of an F:
P(D or F) = [tex]\frac{269}{1052} +\frac{130}{1052}[/tex]
P(D or F) = [tex]\frac{399}{1052}[/tex]
P(D or F) = 0.379
d) Probability of an A or B is also the sum of probabilities of an A and of an B:
P(A or B) = [tex]\frac{68}{1052} +\frac{258}{1052}[/tex]
P(A or B) = [tex]\frac{326}{1052}[/tex]
P(A or B) = 0.31
