Step-by-step explanation:
Number Of Students who go to School by Walk = 27
Number Of Students who go to School by Bus = 45
Ratio of Student who go to School by Walk : Bus = 27 : 45
=> Ratio of Student who go to School by Walk : Bus = 3 : 5
Hence Ratio of Student who walk to students who ride the Bus is 3 : 5 is correct - True Statement
Number Of Students who go to School by Bike = 21
Number Of Students who go to School by Walk = 27
Ratio Bike : Walk = 21 : 27
=> Bike : Walk = 7 : 9
Hence for Every 7 Students who Bike there are 9 students who walk
=> For Every 7 Students who Bike there are 8 students who walk is not Correct
Keira said that if 6 tickets are sold, there should be 2 tickets left. Is Keira correct?
Answers
According to Keira, if 6 tickets are sold, there should be 2 tickets left. However, we don't have any information about the initial number of tickets available.
If the total number of tickets initially was 8, and 6 tickets were sold, then there would indeed be 2 tickets left, supporting Keira's statement.
However, if the total number of tickets initially was less than 8, or if the statement doesn't specify the initial number of tickets, we cannot determine if Keira's statement is correct.
Therefore, without additional information, we cannot determine the accuracy of Keira's statement.

examples of mean, median, and mode
Answers
Answer:
in a group of numbers (2,4,7,9,7,5,7,8,3)
The mean would be 5.2
The mode would be 7
The median would be 7
Explanation:
Say we have a group of numbers (2,4,7,9,7,5,7,8,3)
Lets start by finding the Median! *Remember, the median is the MIDDLE!
So, if the median is the middle, it would be 7.
Lets do the mode now. *Remember the mode is the one that happens the MOST!*
If we take a look at the numbers, we see that 7 occurs the most (it appears 3 times)
Our mode would be 7.
Lastly, lets do the mean. *You add and divide for the mean*
So, we start by adding all of the numbers together.
Basically, ( 2 + 4 + 7 + 9 + 7 + 5 + 7 + 8 + 3) you then get 52.
Next, we divide 52 by all the numbers that we added together (9)
And we get our mean: 5.2

a committee consisting of 4 faculty members and 5 students is to be formed. every committee position has the same duties and voting rights. there are 7 faculty members and 13 students eligible to serve on the committee. in how many ways can the committee be formed?
Answers
and
C(13, 5) = 13! / (5!(13-5)!) = (13 * 12 * 11 * 10 * 9) / (5 * 4 * 3 * 2 * 1) = 1287
Multiply these two combinations since the faculty members and students are selected independently:
Total number of ways to form the committee = C(7, 4) * C(13, 5) = 35 * 1287 = 45,045
Therefore, there are 45,045 ways to form the committee consisting of 4 faculty members and 5 students.
For faculty members:
There are 7 eligible faculty members, and we need to select 4 of them for the committee. This can be done using the combination formula:
C(7, 4) = 7! / (4!(7 - 4)!) = 35.
So, there are 35 ways to select 4 faculty members from the 7 eligible ones.
For students:
There are 13 eligible students, and we need to select 5 of them for the committee. Using the combination formula again:
C(13, 5) = 13! / (5!(13 - 5)!) = 1287.
Therefore, there are 1287 ways to select 5 students from the 13 eligible ones.
To form the committee, we multiply the number of ways to select faculty members by the number of ways to select students:
35 * 1287 = 44,895.
Hence, there are 44,895 ways to form the committee consisting of 4 faculty members and 5 students from the eligible candidates.

Step-by-step explanation:
If it takes a group of 24 students 1,296 minutes to study for an upcoming test, it takes 54 minutes for each student. (=> 1,296/24 = 54)

What is the nth term for 3, 10, 29, 66 and 127?
Answers
Answer:
3, 2, 7, 14, 23.
To find the nth term of a sequence, we need to identify the pattern or rule that generates the sequence.
Looking at the given sequence 3, 10, 29, 66, 127, we can see that each term is obtained by squaring the previous term and subtracting a constant value.
Specifically, we can see that:
10 = 3^2 + 1
29 = 10^2 + 9
66 = 29^2 + 7
127 = 66^2 + 1
So the pattern seems to be that each term is obtained by squaring the previous term and adding a constant value that increases by 2 for each successive term.
To find the nth term, we can use the formula:
nth term = (n-1)^2 + c
where n is the position of the term we want to find, and c is the constant value we add to the square of the previous term.
Using this formula, we can find the nth term as follows:
For the 1st term (n=1), we have 3 as the first term.
For the 2nd term (n=2), we have:
nth term = (n-1)^2 + c
= (2-1)^2 + 1
= 1 + 1
= 2
For the 3rd term (n=3), we have:
nth term = (n-1)^2 + c
= (3-1)^2 + 3
= 4 + 3
= 7
For the 4th term (n=4), we have:
nth term = (n-1)^2 + c
= (4-1)^2 + 5
= 9 + 5
= 14
For the 5th term (n=5), we have:
nth term = (n-1)^2 + c
= (5-1)^2 + 7
= 16 + 7
= 23
Therefore, the nth term for the given sequence is:
3, 2, 7, 14, 23.
hope this helps!
Answer:
Therefore, the 6th term of the sequence is 108.
Step-by-step explanation:
To find the pattern and the nth term for the sequence 3, 10, 29, 66, 127, we can look at the differences between the terms:
7, 19, 37, 61
The second differences are constant, which suggests that the original sequence is a polynomial of degree 2 (a quadratic). To find the formula for this quadratic, we can use the method of finite differences.
The first differences are:
7, 19, 37, 61
The second differences are:
12, 18, 24
The third differences are:
6, 6
Since the third differences are constant, we can assume that the formula for the sequence is of the form an^3 + bn^2 + cn + d, where a, b, c, and d are constants.
Using the first four terms of the sequence, we can set up a system of equations:
a(1)^3 + b(1)^2 + c(1) + d = 3
a(2)^3 + b(2)^2 + c(2) + d = 10
a(3)^3 + b(3)^2 + c(3) + d = 29
a(4)^3 + b(4)^2 + c(4) + d = 66
Solving this system of equations, we get:
a = 1/2
b = 3/2
c = 5/2
d = 1
Therefore, the formula for the nth term of the sequence is:
an^3 + bn^2 + cn + d = (1/2)n^3 + (3/2)n^2 + (5/2)n + 1
So, the nth term for the sequence 3, 10, 29, 66, 127 is:
an^3 + bn^2 + cn + d = (1/2)n^3 + (3/2)n^2 + (5/2)n + 1
To find the 6th term of the sequence, we can substitute n=6 in the formula:
a6 = (1/2)(6)^3 + (3/2)(6)^2 + (5/2)(6) + 1
= 108
Therefore, the 6th term of the sequence is 108.

Answer:
The graph has y-intercept (0,5) and increases with a constant ratio of 3
Step-by-step explanation:
The value of the function when x=0 is 5·3^0 = 5, so the y-intercept is (0, 5).
Each increase of 1 in x causes the function value to increase by a factor of 3, so the 'constant ratio' is 3. (That is the base of the exponential term.)

There are two types of tickets sold at the Canadian Formula One Grand Prix race. The price of 5 grandstand tickets and 3 general admission tickets is 2490. The price of 6 grandstand tickets and 6 general admission tickets is 3540 . What is the price of each type of ticket?
Answers
Answer: Grandstand: 360, General Admission: 230
Step-by-step explanation:
Use any variable you like but:
Let g represent grandstand ticketsLet a represent general admission ticketsYou know:
5 Grandstand tickets and 3 general admission tickets is 2490:
5g + 3a = 2490The price of 6 grandstand (g) tickets and 6 general admission tickets (a) is 3540
6g + 6a = 3540You want to find out: What is the price of each ticket. To do this either use substitution or elimination.
I will demonstrate elimination:
To do elimination, you want to cancel out one variable. This means you want to multiply each side of the equation by a number. I see 3a and 6a. This means multiply by -2. Again, you want to eliminate the variable.
5g +3a = 2490 → -10g - 6a = -4980Now, add the two equations together: Notice how you can line them up vertically to see how they can add together.
-10g - 6a = -4980+6g + 6a = 3540After that step you get: -4g = -1440Now you can solve for the g (grandstand tickets):
-4g = -1440g = 360You now know grand stand tickets cost 360. Take one of your original equations and solve for a (general admission tickets). To double check your work, they should satisfy both equations.
5g + 3a = 24905(360) + 3a = 24903a = 690a = 2306g +6a = 35406(360) +6a = 35406a = 1380a = 230Therefore general admission tickets cost 230, and grandstand tickets cost 360!
