When measuring height, it is necessary to represent both the vertical position and the separation between the minimum and maximum place or location. Rachel is 5 feet 6 inches tall, the tall is her cousin exists 2 feet 9 inches.
What is meant by tall?In math, tall can be defined as the vertical distance from the top to the base of the object. Tall is the distance between an object's highest and lowest points.
The measurement of an object's height from the base to the top is known as tall. It is sometimes referred to as altitude in geometry. The vertical distance between the lowest and highest point is measured. In coordinate geometry, it is often the measurement along the y-axis of an object.
Rachel/Cousin = Rachel's shadow / Cousin's shadow
5 feet 6/x = 2/1
simplifying the above equation, we get
5ft 6 = 2x
x = 5ft 6/2
x = 66in/2
x = 33 in
x = 2ft 9inch
Therefore, the value of x = 2ft 9inch.
Rachel is 5 feet 6 inches tall, the tall is her cousin exists 2ft 9inch.

Solve each system by substitution. Check your answers.
r + s = -12 , 4r - 6s = 12
By substitution, the solution of the system of equations, r + s = -12 and 4r - 6s = 12, is (-6 , -6).
A system of linear equations is a set of two or more equations which includes common variables. To solve system of equations, we must find the value of the unknown variables used in the equations that must satisfy both equations.
There are three methods that can be used to solve system of linear equations.
1. Elimination
2. Substitution
3. Graphing
Using substitution method, given two linear equations in r and s,
r + s = -12 (equation 1)
4r - 6s = 12 (equation 2)
Using the first equation, find the value of one variable, lets say r, in terms of the other.
r + s = -12 (equation 1)
r = -12 - s
Substitute the value of r to the second equation.
4r - 6s = 12 (equation 2)
4(-12 - s) - 6s = 12
-48 - 4s - 6s = 12
Combining all terms containing the variable s on one side and the constants on the other side of the equality, and solving for s.
-48 - 4s - 6s = 12
-4s - 6s = 12 + 48
-10s = 60
s = -6
Substitute the value of s in the equation of r and solve for r.
r = -12 - s
r = -12 - (-6)
r = -12 + 6
r = -6
Hence, the solution of the given system of equations is (-6 , -6).

If P(A | B) is the same as P(A) , and P(B \mid A) is the same as P(B) , what can be said about the relationship between events A and B ?
When P(A | B) = P(A) and P(B ∩ A) = P(B). Then, the given events A and B are independent events.
What is defined as the independent events?Independent events are those where the occurrence is unrelated to any other event.
For example, suppose we toss a coin as in air and the result Head, then we throw the coin again and get the result Tail. Both events occur independently of one another in both cases.Now, as for the given question.
There are two events given as A and B.
The probability of occurrence of event A is P(A).
The probability of occurrence of event B is P(B).
The occurrence of the event A when B is already happened is denoted by P(A | B).
The intersection of events A and B are given as; P(B ∩ A).
Now, it is given in the question that;
P(A | B) = P(A) and P(B ∩ A) = P(B)
And, we already know that, the formula of the conditional probability for event A when event B has already occurred is;
P(A | B) = P(B ∩ A)/P(B)
This can also be written as;
P(B ∩ A) = P(A | B).P(B)
Now, P(A | B) = P(A), replace in the obtained equation.
P(B ∩ A) = P(A).P(B)
The obtained result is the condition for independent events.
Therefore, the events A and B are found to be independent events.

In horse racing, a trifecta is a bet that the first three finishers in a race are selected, and they are selected in the correct order. Does a trifecta involve combinations or permutations? explain.
In horse racing, a trifecta, which is a bet that the first three finishers in a race are selected, and they are selected in the correct order, involves selection done in permutation.
Permutation is the method of selecting or arranging objects or numbers in order. It is used when the order or sequence of the elements selected is important. The number of permutations of n objects taken r at a time is determined by the following formula: P(n , r) = n!
On the other hand, combination is the method of selecting or arranging objects or numbers from a group of objects or numbers where order does not matter. The number of combinations of n objects taken r at a time is determined by the following formula: C(n , r) = n!/[r!(n - r)!]

Use each recursive definition to write an explicit formula for the sequence. a₋₁ = 1, a n =a n ₋₁ +4
The explicit formula for the given sequence is a(n) = 1 + 4(n - 1).
What is termed as recursive definition?A recursive function is one that iterates or uses its very own previous term to determine subsequent terms, resulting in a series of terms.
The recursive formula for an arithmetic sequence is as follows.
a(1) = 1 and a(n) = a(n - 1) + 4.
Remember that this formula provides us with two types of data.
1 is the first term.Add 4 to obtain any term out of its previous term. To put it another way, this same common difference is 4.Let's look for a formal formula again for sequence.
Remember that we can use the standard explicit form to represent a sequence in which the first term is A & common difference is B: A + B(n - 1).As a result, the sequence's explicit formula is a(n) = 1 + 4(n - 1).Thus, by the use of recursive definition, the explicit formula for the sequence is a(n) = 1 + 4(n - 1).

Each sequence has eight terms. Evaluate each related series. -3.5,-1.25,1,. . . . . . , 12.25
An arithmetic progression (AP) is a sequence of numbers ordered such that the difference between any two consecutive numbers is a constant value. Also called arithmetic sequence. For example, the sequence of natural numbers: 1, 2, 3, 4, 5, 6, … is an arithmetic sequence in which the common difference between two consecutive terms (e.g., 1 and 2) is 1 (2 - 1) ... It can be seen that the tolerance of two consecutive terms is equal to 2, even for odd and even numbers.
First term a=-3.5,
Common difference d=2.25,
Number of terms n=8
Solution:
Here first term a=-3.5,
Common difference d=2.25
We know that,
f(n)=a+(n-1) d
f (8)=-3.5+(8-1)(2.25)
=-3.5+(15.75)
=12.25
We know that,
Sn=n2[2a+(n-1)d]
∴S8=82⋅[2(-3.5)+(8-1)(2.25)]
=4⋅[-7+(15.75)]
=4⋅[8.75]
=35
Hence, 8th term of the given series is 12.25 and sum of first 8th term is 35.

Perimeter: 2(7+12), 2*7+2*12, 7+12+7+12
Area: 7*12, 7*10 + 7*2
neither: 7+12
Step-by-step explanation:
perimeter is like if you want a fence all the way around your property and your yard is 7x12 feet. In that case you could use the first option because you have to count the sides and add them up. If it’s a rectangle then there are 2 12’s and 2 7’s so the first one would work. The fourth one also uses distribution. The Fourth and first one are pretty much the same and have the same answer so the fourth one would work for perimeter.
Another way to do perimeter is to instead of multiplying, is to add the sides. 7+12+7+12 is basically 7 times 2 plus 12 times 2 (the fourth ne) and the answer is still correct so this one works too,
For area you times one of the dimensions by the other so 7*12 would work for area.
7*10 + 7*2 would also work because that uses the distributive property and that’s 70 + 14 which is 84 which is still the same answer.
The only one that falls under neither is the fifth one. 7+12 is half of the perimeter because it only adds two of the sides together and has n multiplying so it’s not area either.
Solve without graphing. Find the slope and the y-intercept for the graph of each equation in the given system. Use this information (and not the equations' graphs) to determine if the system has no solution, one solution, or an infinite number of solutions.
For equation (1), we get the Slope as 3 / 4 and y intercept as - 9 and for equation (2), we get the Slope as 3 / 4 and y intercept as - 4.
We are given 2 equations:
y = 3 / 4 x - 9 ...(1)
and y = 3 / 4 x - 4 ... (2)
Slope for equation (1) will be
slope = m1 = 3 / 4
Slope for equation (2) will be
Slope = m2 = 3 / 4
Y intercept for equation (1) will be:
= - 9
Y intercept for equation (2) will be:
= - 4
Also, since the Slope of equation are equal, so, it has no solutions as they are parallel to each other.
Therefore, for equation (1), we get the Slope as 3 / 4 and y intercept as - 9 and for equation (2), we get the Slope as 3 / 4 and y intercept as - 4.

The expression "quantity negative three and one third times n plus one sixth end quantity plus quantity one and three sixths times n minus three twelfths end quantity" or (-3 1/3n + 1/6) + (1 3/6n - 3/12) is equivalent to "negative eleven sixths times n minus one twelfth" or -11/6n - 1/12.
An algebraic expression is a number, variable, or the combination of both and operational symbols.
