What is combination ?
Combinations are mathematical operations that count the number of potential configurations for a set of elements when the order of the selection is irrelevant. You can choose the components of combos in any order. Permutations and combinations can be mixed up.The Munchery Restaurant advertises that you can have a different lunch combination every day of the year.

∠A and \angle B∠B are vertical angles. If m\angle A=(7x+22)^{\circ}∠A=(7x+22)
∘
and m\angle B=(8x+20)^{\circ}∠B=(8x+20)
∘
, then find the measure of \angle A∠A.
Based on the definition of vertical angles, m<A = 36°.
What are Vertical Angles?Two angles that are vertically opposite to each other are called vertical angles, and they have congruent angle measures. That is, vertical angles are equal.
Angles A and B are vertical angles, then, they are equal to each other.
m<A = (7x + 22)°
m<B = (8x + 20)°
m<A = m<B
Substitute
7x + 22 = 8x + 20
7x - 8x = -22 + 20
-x = -2
x = 2
m<A = 7x + 22
Plug in the value of x
m<A = 7(2) + 22
m<A = 14 + 22

suppose your group measures the following three numbers in some experiment: 12.4,7.8,10.2. if you use half the range as an estimate of the standard deviation, what is the standard error on the mean of these numbers?
The standard error on the mean of these numbers is 1.08
For given question,
suppose your group measures the following three numbers in some experiment: 12.4,7.8,10.2
Mean of these numbers is:
[tex]\bar x=\frac{ 12.4+7.8+10.2}{3}\\\\ \bar x=10.13[/tex]
So the standard deviation would be,
[tex]\sigma=\sqrt{\frac{(12.4-10.13)^2+(7.8-10.13)^2+(10.2-10.13)^2}{3} }\\\\\sigma=1.88[/tex]
Now we find the standard error on the mean of these numbers.
[tex]\sigma_M=\frac{\sigma}{\sqrt{N} }[/tex]
where, [tex]\sigma_M[/tex] = standard error of the mean
σ = the standard deviation of the original distribution
N = the sample size
[tex]\sigma_M=\frac{1.88}{\sqrt{3} }\\\\\sigma_M=1.08[/tex]
Therefore, the standard error on the mean of these numbers is 1.08

Write an indirect proof of each statement.
Given: x y is an odd integer.
Prove: x and y are both odd integers.
By assuming that one of the two integers is even we will reach an absurd, and in that way, prove the given statement.
How to prove the statement?
Remember that an odd integer number is written as:
A = (2n + 1)
While an even number would be written as:
B = 2n
Where n is a random integer.
Then if x times y is an odd integer we can write:
x*y = (2n + 1)
Where n, m ∈ Z.
Where Z is the set of integer numbers.
Now, let's do find an absurd. Let's suppose that one of the two numbers is even, then we can write:
x = 2m
And y can be even or odd, it does not matter, but it is an integer.
Replacing that we get:
x*y = (2m)*y
We can rewrite that as:
(2m)*y = 2*(m*y)
We know that integer numbers are closed under the product, and here m and y are integers, then m*y is also an integer.
Thus, 2*(m*y) is 2 times an integer, then that is an even number, which is absurd because we know that it should be odd. So, if at least one of the two integers is even, then the product will also be even.
Then if the product is odd, neither of the integers can be even, then we conclude that both of the integers are odd integers.

An altitude is drawn to the base of equilateral triangle abc. if ac=13, find the length of the altitude.
The length of the altitude of the equilateral triangle ABC is [tex]\frac{13\sqrt{3} }{2}[/tex].
Equilateral Triangle is defined as the triangle with all the sides equal and all the angles = 60 deg.
Altitude of a Triangle can be defined as the perpendicular drawn from the vertex of a triangle to the opposite side.
According to the question
In the figure given below
In ΔADC
Since ΔADC is a right angle triangle we can apply Pythagoras Theorem.
Let the sides of the equilateral triangle be "a". and "h" be the altitude.
Since the altitude is of equilateral triangle it divides the base i.e. DC=a/2
[tex](AC)^{2} =(AD)^{2}+(DC)^{2}[/tex]
[tex]a^{2} =h^{2}+(\frac{a}{2})^{2}\\ \\ h^{2}=\frac{4a^{2}-a^{2}}{4} \\ \\ h=\sqrt{3} *\frac{1}{2} *a[/tex]

angle q and angle r are complementary. the measure of angle q is 26 degrees less than the measure of r. find the measure of each ang;e
Based on the definition of complementary angles, the measures are:
m<q = 32°
m<r = 58°
What are Complementary Angles?Tow angels are complementary if both angles give a sum of 90 degrees.
The sum of angle q and angle r would give 90 degrees because they are complementary angles. Therefore, we would have the following:
m<r = ?
m<q = m<r - 26
Plug in the values
m<r - 26 + m<r = 90
2(m<r) - 26 = 90
2(m<r) = 90 + 26
2(m<r) = 116
2(m<r)/2 = 116/2
m<r = 58°
m<q = m<r - 26 = 58 - 26
m<q = 32°

According to the question, the study is based on the organic pesticide for a particular plant. The pesticide manufacturer is developing a new type of organic pesticide for the particular plants. To understand the application of a new organic pesticide, then perform one experiment where the members of plants have controlled the environment for the testing purpose. In this way, plants can be protected from pest attack. These types of experiments fall under matched pair experiments.

Answer:
1. Not Linear
2. Linear
3. Linear
4. Linear
Step-by-step explanation:
Linear means it follows the form y = mx + b
1. The x value increases by 2 each time, but the y value doubles each time. They are increasing at different rates, so they are not linear.
2. The x value is increasing by 3 each time, and the y value is deceasing by 1 each time. Slope (m) of this line would be -1/3
3. The x value is increasing by 4 each time, the y value is increasing by 3 each time. Slope (m) of this line would be 4/3
4. The x value is increasing by 1 each time, the y value is constantly -3. This means that the line is a horizontal line, which is linear with a slope of 0. So the equation of this line would be y = 0x -3 ----> y = -3

Similarly, Q1 is obtained as the median of the lower half as (7+1)/2th = 4th observation i.e 60.
Similarly, Q3 is obtained for the upper half as 79 (4th upper half)
IQR (Interquartile Range) = Q3 - Q1 = 79 - 60 = 19
What is Interquartile Range?The interquartile range is a gauge for where a data set's "middle fifty" lies. An interquartile range (IQR) measures where most of the values lay, whereas a range measures where a set's start and finish are. For this reason, it is preferable when reporting things like academic performance or SAT scores over many other measures of spread.
The interquartile range IQR is 19
In ascending order we have: 48,51,57,60,63,65,69,71,72,73,75,79,85,88,97
Also, we get sample size (n) = 15 (odd)
So, Median = Q2 = (n+1)/2th observation
Median = (15+1)/2th term = 8th observation
Median = Q2 = 71
The formula for the interquartile range is the first quartile less the third quartile:
