can someone please simply teach me what mean, median, and mode is pls pls pls
Mean is when you sum up all the numbers in a data set and divide that sum with the total amount of numbers in the data set.
Median is the middle number of a data set.
Mode is the number that shows up the most in a data set.
Best of Luck!
Answer:
The mean is the average of a data set. The mode is the most common number in a data set. The median is the middle of the set of numbers.

Step-by-step explanation:
3x - y = 74
4y = x
Replace x in the first expression by 4y
3x - y = 74 ➡ 3(4y) - y = 74
12y - y = 74
11y = 74
y = 74/11 we can use this to find x
4y = x
4 × 74/11 = x
296/11 = x

Tickets to the movies are $7 for adults and $4 for children. If 272 tickets
sold $1694, then how many of each type were sold?
Answer:
202 tickets for adults were sold and 70 tickets for children are sold.
Step-by-step explanation:
Solve this question using simultaneous linear equation.
•Let the number of tickets sold for adults be a
•Let the number of tickets sold for children be b
The question stated that 272 tickets were sold altogether. So:
[tex]a + b = 272[/tex]
Now, make sure that only one of the unknown values remain on the left hand side. For example:
[tex]a = 272 - b[/tex]
I will refer to the above equation as equation 1.
Now, the question also stated that the tickets sold $1694. This means that:
[tex]7a + 4b = 1694[/tex]
I will refer to this equation as equation 2.
Now, substitute equation 1 into equation 2 by replacing the a in equation 2 with the values on the right hand side in equation 1. For example:
[tex]7(272 - b) + 4b = 1694[/tex]
Then just solve the equation by finding the value of b.
[tex]7(272 - b) + 4b = 1694 \\ 1904 - 7b + 4b = 1694 \\ 1904 - 3b = 1694 \\ 1904 - 1694 = 3b \\ 210 = 3b \\ b = 210 \div 3 \\ = 70[/tex]
Lastly, find the value of a. Just take the value of b and then substitute into equation 1.
[tex]a = 272 - b \\ = 272 - 70 \\ a = 202[/tex]
6x + 2y = 18 -4x - 2y = -6
Answer:
x=6, y = -9
Step-by-step explanation:
6x + 2y = 18
-4x - 2y = -6
Add the two equations together to eliminate y
6x + 2y = 18
-4x - 2y = -6
------------------------
2x +0y = 12
Divide by 2
2x/2 = 12/2
x = 6
Then find y
6x+2y = 18
6*6 +2y = 18
36+2y = 18
Subtract 36 from each side
36+2y-36 = 18-6
2y = -18
Divide by 2
2y/2 = -18/2
y = -9

Jin’s soccer team has 4 coaches and 22 players, and his twin sister’s team has 2 coaches and 11 players. If the relationship between the number of players and coaches is proportional throughout the league, which ordered pair could represent the total number of coaches and players in the entire league?
Answer:
B
Step-by-step explanation:
A graph of the Soaring Cupcake’s cost per cupcake is shown below. The graph shows a relationship between the number of cupcakes purchased, n, and the total cost of the order, t. The Soaring Cupcake charges a $15 initial fee and then $3.00 for every cupcake purchased. What is the total cost for 15 cupcakes? What is the total cost for 10 cupcakes? How many cupcakes can you order for $30? Write a function rule in function notation for the situation using the variables t and n: A.) Does an input value of 4 make sense for this situation, why? B.) Does an input value of 5.2 make sense for this situation, why?
Answer:
1) $60
2) $45
3) 5 cupcakes ;; function for situation is 30(n)=3n+15
3A) No
3B) No
Step-by-step explanation:
the function is f(x)=3x+15 where x= cupcakes
To find total cost for 15 cupcakes, simply look at the graph or if you don't trust your eyeballing skills, you would calculate it by:
f(15)=3x+15 meaning plug 15 into the equation which equal $60
same for 10 cupcakes
f(10)=3(x)+15 equals $45
# of cupcake order for $30
using the graph we can see that for $30 we can purchase 5 cupcakes
the function for the situation is 30(n)=3n+15
A) No it would not make sense because after substituting 4 for the n, it does not equal to 30
B) Yes it would make sense because substituting 5.2 for n, it equal to $30.6 or $30

Tai’s baby brother weighs 3,745 grams. What is his weight in kilograms? A. 0.3745 kg B. 3.745 kg C. 37.45 kg D. 374.5 kg
Answer:
My answer to the question is 3.745kg.
Option B
The required weight of Tai's baby brother weighs 3,745 grams in kilograms is 3.745 kg. Option B is correct.
Given that,
Tai’s baby brother weighs 3,745 grams. What is his weight in kilograms is to be determined.
A kilogram is the standard unit of measurement of weight.
What is arithmetic?In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,
Here,
1 kilogram = 1000 gram
1 gram = 1 / 1000 kilogram
Multiply both side by 3,745
3,745 gram = 3,745 / 1000 kilogram
3,745 gram = 3.745 kilogram
Thus, the required weight of Tai's baby brother weighs 3,745 grams in kilograms is 3.745 kg. Option B is correct.

A building contractor estimated the cost of construction on a house would be between
$235.000 and $297,000. He has already spent $164,000. How much more can he spend
and remain within his budget?
Help please
Answer:
$133,000
Step-by-step explanation:
The upper end of the contractor's budget is $297,000. If he has already spent $164,000, he can spend as much as ...
$297,000 -164,000 = $133,000
without exceeding his budget.
He can spend $133,000 more and remain within budget.
__
Additional comment
Of course, he'd like to come in at the low end of the cost range, so would be very happy to spend only $71,000 more.

In a family of 4 children under 10 years old, the sum of the square of the ages of the 3 youngest is equal to the square of the age of the oldest. How old are these children
Answer: 2, 3, 6 and 7.
Step-by-step explanation:
We have four natural numbers A, B, C and D.
such that all of these numbers are smaller than 10, and:
A < B < C < D.
A, B and C are the ages of the smaller ones, and D is the age of the larger kid.
Now we have the relation
A^2 + B^2 + C^2 = D^2
We can write this as:
D = √(A^2 + B^2 + C^2)
And remember that D must be smaller than 10, then now we can play with the numbers A, B and C in order to find D.
Suppose for example:
A = 1, B = 2, C = 3
D = √( 1^2 + 2^2 + 3^2) = √(1 + 4 + 9) = √14
This is not a whole number.
Then we have that A^2 + B^2 + C^2 must be a perfect square.
The perfect squares we can aim for are:
4*4 = 16
5*5 = 25
6*6 = 36
7*7 = 49
8*8 = 64
9*9 = 81
now, looking at that comes to my mind to try to reach the 49.
because we can take the 36, add 4 to that (4 = 2*2) and then add 9 (9 = 3*3)
A^2 + B^2 + C^2 = 49
where we can use:
A = 2. B = 3 and C = 6
2^2 + 3^2 + 6^2 = 4 + 9 + 36 = 49
Then we have:
D = √(2^2 + 3^2 + 6^2 ) = √49 = 7
Then the ages of the children (for smallest to largest) are:
2, 3, 6 and 7.

Use inverse operations to find the inverse of y = 27x?
The inverse of y = 27x3 is y =
Answer:
y = (∛x)/3
Step-by-step explanation:
To undo the multiplication by 27, you multiply by its inverse:
(1/27)y = (1/27)(27x^3)
y/27 = x^3 . . . . . . . . . . . simplify
To undo the cube, you take the cube root:
(∛y)/(∛27) = ∛(x^3)
(∛y)/3 = x
Apparently, you want the inverse function, so you swap the variables:
y = (∛x)/3
_____
You can swap the variables at the beginning or end. It doesn't matter. If you do it at the beginning, you have ...
x = 27y^3
and you're solving for y. You use the same inverse operations that we used above.
