The GCF can be applied to problems requiring the division of something into equal groups or an equal number of groups, as well as problems requiring the simplification of a fraction.
The LCM can be used to solve problems involving the overlap of two activities or something similar, as well as problems involving the addition of two or more fractions with different denominators.
What is the GCF?The greatest common factor of two or more integers that are not all zero in mathematics is the largest positive integer that divides each of the integers.
A set's greatest common factor (GCF) is the largest factor that all of the numbers share.
For example, the numbers 12, 20, and 24 all have two common factors: 2 and 4. The greatest is 4, so the GCF of 12, 20, and 24 is 4. The LCM, or smallest common multiple, is the smallest common number or multiple of any two numbers. The least common multiple of 3 and 5 is 15, for example.

Explained the quotient property "one of the properties of logarithms, the division becomes subtraction" has been explained with an example
In one of the properties of logarithms, the division becomes subtraction. That is the quotient property of the logarithm
Consider the two positive numbers x and y and a ≠ 0
Then,
[tex]log_a[/tex] (m /n) = [tex]log_a[/tex] m - [tex]log_a[/tex] n
Here division became the subtraction
For example
To find the value of [tex]log_2[/tex] (15/ 7) we will use the quotient property of logarithm, here the division of the numbers will be subtraction
[tex]log_2[/tex] (15 / 7) = [tex]log_2[/tex] 15 - [tex]log_2[/tex] 7

1) Figure A
2) Figure B
Answer:
Figure B.
Step-by-step explanation:
Figure A uses what is visually similar in size cylinders to give a detailed image of the amount of money (assumingly as profit). Each given cylinder that is in similar size represents $200, and so it is easy to figure out how the amount of money per store.
In the case of Figure A,
Save Store = $400

The probability that the sample mean diameter surpasses 71 when n = 30 is 0.5 if the distribution is normal (the quoted article makes this assumption and even gives the related normal density curve).
The likelihood that the sample mean diameter exceeds 71 when n = 30 is 0.5, since the normal distribution is symmetric around the mean. This means that there is a 50% probability of the sample mean diameter being above the mean, and a 50% probability that it is below the mean.

Problem 9. Find the perimeter of quadrilateral PORS with the vertices P(-2-2), Q(-1,3), R(5,3), and S(4,-2)
Answer:
Perimeter is 12+2√26
Step-by-step explanation:
Question:
The perimeter of quadrilateral PQRS with the vertices
P(-2, -2), Q(-1, 3), R(5, 3), and S(4, -2)
Find distances PS and QR:
Notice the y-coordinates are the same for 2 pairs of points
P(-2, -2), S(4, -2) and Q(-1, 3), R(5, 3)
So the distance PS = |-2|+4= 6 and QR = |-1|+5 = 6
Find the distances PQ and SR:
Use the distance formula:
[tex]d= \sqrt{(x_{2}-x_{1} ) ^{2} + (y_{2}-y_{1} ) ^{2} }[/tex]
P([tex]x_{1}[/tex] = -2, [tex]y_{1}[/tex] = -2), Q( [tex]x_{2}[/tex] = -1, [tex]y_{2}[/tex] = 3)
PQ = [tex]\sqrt{(-1--2)^{2} +(3- -2)^{2} } = \sqrt{1^{2} +5^{2} } = \sqrt{26}[/tex]
SR = [tex]\sqrt{26}[/tex], because of PQ and SR are equal.
Find the perimeter of quadrilateral PQRS:
The perimeter is equal to the sum of all sides of the quadrilateral.
P= PS + QR + PQ + SR = 6+6+ √26 +√26 = 12+2√26

g what is the probability of flipping at least 3 heads in 4 flips of 2 fair coin given that the first flip is heads?
The probability is 0.25.
What is probability?
Probability is the ability to happen. The subject of this area of mathematics is the occurrence of random events. From 0 to 1 is used to express the value. To determine how likely an event is to occur, mathematics has created the concept of probability.
Given there are 2 coins flipped 4 times, we get the following sample space
S = {HHHH, HHHT, HHTH, HHTT, HTHH, HTHT, HTTH, HTTT, THHH, THHT, THTH, THTT, TTHH, TTHT, TTTH, TTTT}
Now, A = event of having at least 3 heads.
A= {HHHH, HHHT, HHTH, HTHH, THHH}
The number of events having the first flip heads is 4.
Therefore, the probability is:
P(A) =
[tex]=\frac{successful \space\ events}{total\space\ sample\space\ events}\\=\frac{4}{16}\\=0.25[/tex]
Therefore, the probability of flipping at least 3 heads in 4 flips of 2 fair coins given that the first flip is heads is 0.25.

The horse was worth it for $1800.
What is proportion?
A mathematical comparison of two numbers is called a proportion. Ratios and fractions are the main bases on which proportion is explained. Two ratios are equal when they are expressed as a fraction in the form of a/b, ratio a:b, and then a proportion. In this case, a and b can be any two integers.
Based on the given question condition, where, 'h' denotes the amount for the horse in dollars, the proportion can be defined as:
or, [tex]\frac{19200 + h}{12} = \frac{10450+h}{7}[/tex]
or, (19200 + h)7 = (10450 + h)12

The equation that will be used to solve the given question is [2.75x+3.10=27.85] and with the help of this equation we know that Aaden took a ride of 9 miles.
What is an equation?The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions.
For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign.
So, we know that:
The pick-up fee that the company charges is: #3.10
Ride charges per mile: $2.75
Total fare price: $27.85
So, let x be the number of miles ridden, the equation that will be used to solve the given question will be:
2.75x + 3.10 = 27.85
Now, solve as follows:
2.75x + 3.10 = 27.85
2.75x = 27.85 - 3.10
2.75x = 24.75
x = 24.75/2.75
x = 9
Therefore, the equation that will be used to solve the given question is [2.75x+3.10=27.85] and with the help of this equation we know that Aaden took a ride of 9 miles.

What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the percentage increase in the population be = A
Now , the equation will be
The initial population of the city = 117,000
The increase in population of the city = 136,890
Now , the percentage increase in population is given by the formula
initial population of the city + ( A / 100 ) x initial population of the city = increase in population of the city
So , on substituting the values in the equation , we get
Percentage increase in population = 117000 + ( A/100 ) x 117000 = 136890
117000 + ( A/100 ) x 117000 = 136890
Subtracting 117000 on both sides of the equation , we get
( A/100 ) x 117000 = 19890
Divide by 117000 on both sides of the equation , we get
A / 100 = 0.17
Multiply by 100 on both sides of the equation , we get
A = 17 %
Therefore , the value of A is 17 %
Hence , The percentage of increase in the population is 17 %
