Using mathematical operations, Maury bought 6 tickets at the Ticket Outlet if he paid $77 at $12 each.
What are the mathematical operations?The basic mathematical operations are addition, subtraction, multiplication, and division.
These basic operations are used to manipulate numbers and variables in mathematical expressions to produce mathematical results.
The first mathematical operation used here is the subtraction operation.
After subtracting the fixed cost from the total cost, the difference is the total variable cost.
This difference is then divided by the unit variable cost to get the number of tickets.
The unit cost of the ticket = $12
The service charge (fixed cost) = $5
The total cost = $77
The number of tickets bought = 6 ($77 - $5)/$12
Thus, using mathematical operations, Maury did buy 6 tickets for $77.

Solve the quadratic equation x2 + 3x = 40 using the quadratic formula.
A)
x = –8, x = 5
B)
x = 5, x = 8
C)
x = –5, x = 8
D)
x = –8, x = –5
After solving the quadratic equation x² + 3x = 40 using the quadratic formula, (A) x = –8, x = 5
We can solve this quadratic formula by following a few steps.
The given equation is,
x² + 3x =40
Let's subtract 40 from both sides,
x² + 3x - 40 =40 - 40
Or, x² + 3x - 40 = 0
Now, we have to find a suitable pair of factors of -40 which is capable to generate +3 ( coefficient of x ).
The required pair is 8 and -5, and ( 8 - 5 ) = 3
[ -40 = 8 × -5 ]
Therefore, x² + 3x - 40 = 0
Or, x² + ( 8 - 5 )x - 40 = 0
Or, x² + 8x - 5x - 40 = 0
Or, x ( x + 8 ) - 5 ( x + 8 ) = 0 [ taking x and 5 as common ]
Or, ( x + 8 ) ( x - 5 ) = 0 [ taking ( x + 8 ) as common ]
If the multiplication or product of two or more terms is zero, then we can write each term as zero.
Hence we can write,( x + 8 ) = 0
Or, x = -8 ( by subtracting 8 from both sides )
Again we can write,( x - 5 ) = 0
Or, x = 5 ( by adding +5 with both sides )
Now, we can conclude that x = -8 and 5.

This is sequence and the is equal to .
The given series is a geometric sequence with a common ratio of 1/2 it is also written as 0.5.
What is geometric sequence?A geometric progression, also known as a geometric sequence, is a non-zero number sequence in which each term after the first is found by multiplying the previous one by a fixed, non-zero number known as the common ratio.
Number sequences are groups of numbers that adhere to a pattern or rule. A geometric sequence is one in which the rule is to multiply or divide by a specific number each time.
We have,
20, 10, 5, …
The distinction between consecutive terms is:
10 - 20 = -10
5 - 10 = -5
Since -10 ≠ -5, therefore the given series has no standard difference, which means the given sequence is not arithmetic.
The ratio between consecutive terms is:
10/20 = 1/2

Ming estimated that there would be 21 members in his bicycle club by the end of summer. There were actually 15 members at the end of summer. What is the percent error of Ming’s estimate?
The percent error of Ming’s estimate is 40%.
What is Algebraic expression ?
Algebraic expressions are the idea of expressing numbers using letters or alphabets without specifying their actual values. The basics of algebra taught us how to express an unknown value using letters such as x, y, z, etc. These letters are called here as variables. An algebraic expression can be a combination of both variables and constants. Any value that is placed before and multiplied by a variable is a coefficient.
here, it is given that :
Estimated number of members in his bicycle club by the end of summer = 21
Actual number of members in his bicycle club by the end of summer = 15
Now, the percent error of Ming’s estimate :
percent error = {(21-15)/15 } x 100
percent error = (6/15) x 100
percent error = 40%
Therefore, the percent error of Ming’s estimate is 40%.

The equation in slope-intercept form of the line passing through the given points is, y = (-1/2)x + 1
A table containing values of x and y is given:
x y
-2 2
0 1
2 0
4 -1
So the points on the line are:
(-2,2), (0,1), (2,0) and (4,-1)
The equation in slope-intercept form of a line is,
y = mx + c,
where m is the slope of the line and c, the y-intercept of the line.
So we need to find the slope and the y-intercept of the line from the given table values.
Let (x₁, y₁) = (-2,2) and (x₂, y₂) = (0,1).
Then slope of the line, m = (y₂-y₁)/(x₂-x₁)
= (1-2)/(0- -2)
= -1/2
The y-intercept of a line is the y-co-ordinate of the point which intersect the y-axis. I.e., it is the y-co-ordinate of the point at which x = 0.
From the table, when x = 0, y = 1.
Hence the y-intercept, c = 1.
So finally, the equation in slope-intercept form of the line is,
y = (-1/2)x + 1

researchers studying meditation contacted over 1{,}0001,0001, comma, 000 randomly selected adults in 101010 nations. the results showed that those who meditated on a regular basis were less likely to suffer from stress than adults who meditate less regularly or not at all. can we conclude that meditating caused the lower stress? why?
Not necessarily, because this was not an experiment.
In my opinion, Yet scientific evidence from case studies, surveys of meditator experiences, and historical studies is emerging to show that meditation can be associated with stress, negative effects, and mental health problems. Meditation can induce a state of deep relaxation and a calm mind. During meditation, you focus your attention and eliminate the stream of disorganized thoughts that can fill your mind and cause stress. This process can lead to increased physical and emotional well-being.

Answer:
The first 4 terms are 3,9,15, and 21
Step-by-step explanation:
The first term in the recursive formula is 3 (it is important because that would be the number we substitute for the second term. This logic also applies to finding the next term with the answer to the previous term) The formula is an = a(n-1) + 6. Because of this formula the nth on the right side is the previous one plus 6. With that in mind let find the mext three terms To find a2 you would first substitute n for 2 making it a2 = a(2-1) +6 which is a2 = a1 + 6. We know that the first term is 3 so we substitute a1 for 3 to get a2 = 3 + 6 which is 9. The second term is 9 To find a3 we do the same steps for solving a2 only this time we use the second term to put in place of a2+ 6 which is 9 + 6 which equals to 15. The third term is 15 Again we are doing the same steps to find a4 but we use the third term to substitute for a3 + 6 which is 15 + 6 which equals to 21. The fourth term is 21.There's a image of all of the work above

3(5-x)-2(5+x)=3(x+1) solve for x
Primarily use the Distributive Property to solve this equation.
3(5 - x) - 2(5 + x) = 3(x + 1)
Distribute the outer terms.
3(5) + 3(-x) - 2(5) - 2(x) = 3(x) + 3(1)
15 - 3x - 10 - 2x = 3x + 3
-3x - 2x + 15 - 10 = 3x + 3
-5x + 5 = 3x + 3

What is proportional relationship?
Relationships between two variables that are proportional occur when their ratios are equal. Another way to consider them is that in a proportionate relationship, one variable is consistently equal to the other's constant value. The "constant of proportionality" is the name of this constant. In mathematics, proportionality denotes a linear relationship between two quantities or variables. Both quantities increase in size when one doubles, and both decrease in size when one drops to a tenth of its original value.
Given.
The proportion is: according to the first row of the proportional relationship
y = kx

EXPLANATION:
Given;
We are given a graph of a function.
Required;
We are required to determine from the graph if the function is even, odd or neither even nor odd.
Solution:
To determine this from a graph, we should note that a function which is symmetrical with the y-axis is an even function. The graph which is symmetrical with the origin after a 180 degree rotation is an odd function.
Observe that if this graph is flipped from left to right (across the y-axis), it would not retain its original shape.
However, if the graph is rotated 180 degrees about the origin, it would retain its original shape.
Therefore, the graph depicted is an odd function
