a local winery bottles 14 different white wines. to help customers with their purchasing choice, the winery offers customers 5 white wine tasting samples free of charge 2002 many ways does a customer have to choose 5 different white wines to taste, using the concept of combination formula.
What is combination formula?The number of possible ways to choose items from a collection when the order of choice is irrelevant is determined using the combination formula. Combination, to put it simply, is the process of choosing items or things from a bigger group where order is irrelevant.
The combination formula is: n! / (n-r)! r! , where n is the total number of items (14 in this case) and r is the number of items being selected at once (5 in this case),
Plugging our numbers into the formula we get:
= 14! / (14-5)! 5!
= 2002
After simplifying, we get 2002.
So, there are 2002 ways of picking 5 different white wines to taste from a group of 14 local winery bottles.

What is a linear equation?A linear equation has the algebraic form y=mx+b. where m is the slope and b is the y-intercept, consisting of a first-order (linear) term and a constant. If x and y are variables, the above is sometimes called a "two-variable linear equation".
Tickets for a high school dance were provided.
Purchases made before the dance cost $4.00 apiece.
If purchased at the door, they would cost $5 apiece.
225 tickets were sold, bringing in $950.

The population 2 hours before that is 2691 if the population of a colony of bacteria increases by 4% of what the population was at the beginning of the hour.
What is meant by population?A population is a distinct group of individuals that can be distinguished for the purposes of data collection and analysis by at least one feature. Populations are used in statistics and other branches of mathematics. Data is typically collected from a sample while learning about a large population.
Between sample size and population, the population will always be larger in number. The entire group of individuals under study is referred to as the population. 250 persons make up the population in the illustration, which is the same size as the high school under consideration.
We have P₀=2488
Rate of increase=R=4%
Time=2 hours
Bacteria count =P
P=P₀[tex](1+(R/100)^{T}[/tex]

By using the concept of function, it can be seen that the given figure does not represents a function.
What is a function?
A function from A to B is a rule that assigns to each element of A a unique element of B. A is called the domain of the function and B is called the codomain of the function.
There are different operations on functions like addition, subtraction, multiplication, division and composition of functions.
Here the values on the x axis represents the domain and the values on the y axis represents the Range.
From the figure it can be seen that
For x = 2, there are three points on the y axis.
So the point x = 2 maps to different points on the y axis
So this is not a function

One person calls 3 people. The next day, those people each call
3 people. The third day, those people each call 3 people. Write
an expression using exponents for the number of calls made on
the third day.
Answer:
3³
Step-by-step explanation:
You want an expression using an exponent to represent the number 3·3·3.
Repeated multiplicationAs you know, a coefficient is used to represent repeated addition:
a + a + a = 3a
The coefficient 3 in the above expression signifies that 'a' appears in the sum 3 times.
Likewise, repeated multiplication can be represented using a specific notation. An exponent signifies the number of times a factor appears in a product:
a · a · a = a³ . . . . . 'a' is a factor 3 times
ApplicationYou have a sequence of numbers of telephone calls:
3 the first day
3·3 the second day
3·3·3 the third day
The calls on the third day can be represented using an exponent:
3³
__
Additional comment
When superscript formatting is not available for the exponent, it is signified by a caret (^). The same number is 3^3 when written in plain text.
As you might expect, a plain text exponent must be enclosed in parentheses if it is other than a single letter or number.
A, B, C and D lie on a circle.
AC and BD intersect at X.
The angles BAX and CDX are equal and the length of CX is 8.2 cm.
What are angles?
An angle is a figure in plane geometry that is created by two rays or lines that have a shared endpoint. The Latin word "angulus," which meaning "corner," is the source of the English term "angle." The shared terminus of two rays is known as the vertex, and the two rays are referred to as sides of an angle.
Given that, the points A, B, C, D lie on a circle and AC and BD intersect at X.
The angles BAX and CDX, they are subtended by the same arc AD, hence, according to the property of angles subtended by the same arc, they are equal.
Thus ∠BAX = ∠CDX
Since, corresponding sides opposite to the equal angles are proportional.
CX/BX = CD/AB
⇒ CX/3.84 = 9.40/4.40
⇒ CX = (9.40*3.84)/4.40
⇒ CX = 8.2
Thus, length of CX is 8.2cm
The angles BAX and CDX are equal and the length of CX is 8.2 cm

It takes Elijah 8 minutes to run 4 laps how many minutes does it take him to run 1 lap?
Topic is unit rate
Answer:
2 minutes
Step-by-step explanation:
8 : 4 = x : 1
x = 8/4
x = 2
Step-by-step explanation: To find the time it takes Elijah to run 1 lap, we need to divide the time it takes him to run 4 laps by the number of laps he runs in that time. Since it takes Elijah 8 minutes to run 4 laps, the time it takes him to run 1 lap is 8 minutes / 4 laps = ${2}$ minutes per lap.
This calculation illustrates the concept of unit rate, which is the rate at which a quantity changes over a given unit of time or distance. In this case, the unit rate is the time it takes Elijah to run 1 lap, which is 2 minutes per lap. This unit rate allows us to compare the time it takes Elijah to run different distances, and to determine how long it would take him to run a given distance at the same pace.
Consider the following points on the graphs of y = cos(x) and y = cos(x/2), with the added vertical dashed lines:

What is sinusoidal wave?
A mathematical curve defined in terms of the sine trigonometric function, of which it is the graph, is known as a sine wave, sinusoidal wave, or simply sinusoid. It is a smooth periodic function and a particular kind of continuous wave.
Let the graphs of y = cos(x) and y = cos(x/2) are given.
From this graphs we have to find the value of c and d.
First from y = cos(x) to find the value of 'a'.
Consider, the point [tex](a, \frac{1}{8})[/tex]
⇒
[tex]cos(a) = \frac{1}{8} \\a = cos^-^1(\frac{1}{8})\\ a = 82.82[/tex]
Now to find the value of 'c'.
Plug a = 82.82 in y = cos(x/2).
[tex]cos(\frac{82.82}{2}) = c \\c = -0.84[/tex]
Hence, the value of 'c' is 'c = -0.84'.
Now to find the value of 'd'.
Consider, the point [tex](b, \frac{1}{8})[/tex]
⇒
[tex]cosb = \frac{1}{8} \\b = cos^-^1(\frac{1}{8})\\b = 82.82[/tex]
Now, plug b = 82.82 in y = cos(x/2)
[tex]cos(\frac{82.82}{2}) = d\\ d = 0.84[/tex]
Hence, from the given graphs the values of 'c' and 'd' are c = -0.84,
d = 0.84.

chicken and 1.8 pounds of fish. How much does each cost per pound?
Each pound of fish and chicken will cost $3.75 and $2.25 respectively
How to determine how much each cost per pound?
A word problem is a mathematical exercise where significant background information on the problem is presented in ordinary language rather than in mathematical notation
Given that:
1. A customer pays a total of $11.10 for 1.6 pounds of chicken
and 2 pounds of fish.
2. Another customer pays a total of $12.15 for 2.4 pounds of
chicken and 1.8 pounds of fish
Let C and F represent the cost of one pound of chicken and fish respectively
Statement 1:
1.6C + 2F = 11.10 ---- (1)
Statement 2:
2.4C + 1.8F = 12.15 ---- (2)
we have simultaneous equations now, let's solve using the elimination method:
1.6C + 2F = 11.10 ---- (1)
2.4C + 1.8F = 12.15 ---- (2)
2.4 × (1.6C + 2F = 11.10) = 3.84C + 4.8F = 26.64
1.6 × (2.4C + 1.8F = 12.15) = 3.84C + 2.88F = 19.44
..........................................
1.92F = 7.2
Thus, 1.92F = 7.2
F = 7.2/1.92 = $3.75
Put F = $3.75 into (1):
1.6C + 2F = 11.10
1.6C + 2(3.75) = 11.10
1.6C + 7.5 = 11.10
1.6C = 11.10 - 7.5
1.6C = 3.6
C = 3.6/1.6 = $2.25

The solution of the system of equations is y = 5 and x = 3, and the difference x - y gives:
x - y = -2
How to solve the system of equations?Here we have the system of equations:
5x + 3y = 30
-5x - 2y = -25
If we add the two equations we will get:
(5x + 3y) + (-5x - 2y) = 30 + (-25)
y = 5
So just by doing that we found the value of the variable y.
To find the value of x, we can replace the known value of y on one of the equations, doing that we will get:
5x + 3y = 30
5x + 3*5 = 30
5x + 15 = 30
5x = 30 - 15 = 15
x = 15/5 = 3
x = 3
