Look at this square. Find the value of
S.
S
Perimeter = 16 miles
S =
miles
The value of S, which represents the length of each side of the square, is 4 miles.
To find the value of S, we need to determine the length of each side of the square. Given that the perimeter of the square is 16 miles, we can use the formula for the perimeter of a square, which is 4 times the length of a side.
Perimeter = 4 × S
Given that the perimeter is 16 miles, we can substitute this value into the equation:
16 = 4 × S
To solve for S, we divide both sides of the equation by 4:
16 ÷ 4 = S
4 = S
Therefore, S, which stands for the square's side lengths, has a value of 4 miles.
So, S = 4 miles.
This means that each side of the square measures 4 miles, and the square has equal sides and right angles at each corner.

a score of x = 70 on an exam with µ = 82 and σ = 8, or a score of x = 60 on an exam with µ = 72 and σ = 12?
A score of x = 60 on an exam with μ = 72 and σ = 12 is comparatively better than a score of x = 70 on an exam with μ = 82 and σ = 8.
To compare the two scores, we can convert them to z-scores, which tell us how many standard deviations a particular value is from the mean. The formula for z-score is:
z = (x - μ) / σ
where x is the value, μ is the mean, and σ is the standard deviation.
For the first score of x = 70 on an exam with μ = 82 and σ = 8, the z-score is:
z = (70 - 82) / 8 = -1.5
For the second score of x = 60 on an exam with μ = 72 and σ = 12, the z-score is:
z = (60 - 72) / 12 = -1.0
The z-score for the first score is lower than the z-score for the second score, which means that the first score is further below its mean than the second score is below its mean. Therefore, we can say that a score of x = 60 on an exam with μ = 72 and σ = 12 is comparatively better than a score of x = 70 on an exam with μ = 82 and σ = 8.

Solve 2y + x + 3 = 0 and 3y - x + 1 = 0 graphically using -4 ≤x ≤ 2
help pls
Answer:
Step-by-step explanation:
We have to the graph from x = -4 to x = 2
2y + x + 3 = 0
Rearrange the equation to make y the subject
2y = -x - 3
y = (-1/2)x -3/2
-3/2 is the y intercept
the gradients is -1/2
since the value is negative, the graph will be sloping downwards
Point your pen at y = -3/2 on the y axis (-3/2 is -1.5)
go 1 point down and 2 points to the right, make a point and connect these 2 dots and make a line across the graph.
Do the same with the other equation:
3y - x + 1 = 0
3y = x - 1
y = (1/3)x -1/3
y intercept is -1/3
gradient is 1/3
point your pen at -1/3 on the y axis, go 1 point up and 3 points to the right
and mark this point and connect these 2 points and make a line across the graph.

Find the limit of the sequence: an 2n2+4n+3 8n2 +6n+6 Limit____
To find the limit of the sequence, we need to take the value of "n" to infinity.
So, let's divide both the numerator and denominator by the highest power of "n", which is "2n^2".
an = (2n^2 + 4n + 3) / (8n^2 + 6n + 6)
Now, as "n" tends to infinity, the terms with lower powers of "n" become insignificant. Therefore, we can neglect the terms "4n" and "6n" in the numerator and denominator.
an = (2n^2 + 3) / (8n^2 + 6n + 6)
Now, taking the limit of the sequence as "n" tends to infinity:
limit = lim(n → ∞) [(2n^2 + 3) / (8n^2 + 6n + 6)]
Using the rule of L'Hopital's rule, we can differentiate the numerator and denominator separately with respect to "n".
limit = lim(n → ∞) [(4n) / (16n + 6)]
As "n" tends to infinity, the denominator becomes very large, and the term "6" becomes insignificant. So,
limit = lim(n → ∞) [(4n) / (16n)]
limit = lim(n → ∞) [1 / 4]
limit = 1/4
Therefore, the limit of the sequence is 1/4.

A square garden has an area of 400 square feet. Each side of the garden is (x-10) feet in length.
Write an equation that represents the AREA of the garden
Find the value of x using the square root method
What is the length of the side of the garden?
Answer:
400 = (x - 10)²
x² -20x -300 = 0
x = 30 and x = -10
Length side of the garden = 20 feet
Step-by-step explanation:
Given:
Area of square garden = 400 square feet
Length side of the garden = (x - 10) feet
Find:
Length side of the garden
Computation:
Area of square = side²
Area of square garden = Length side of the garden²
400 = (x - 10)²
400 = x² -20x + 100
x² -20x -300 = 0
x² -30x + 10x -300 = 0
x(x - 30) + 10(x - 30) = 0
(x - 30)(x + 10) = 0
So,
x = 30 and x = -10
Use x = 30 positive number
Length side of the garden = (x - 10) feet
Length side of the garden = (30 - 10) feet
Length side of the garden = 20 feet
Let R be a relation on a set A and suppose R is symmetric
and transitive. Prove the following: If for every x in A
there is a y in A such that x R y, then R is an equivalence
relation.
please state proof technique and explain
R is transitive. it is an equivalence relation. We used direct proof technique to prove this.
To prove that R is an equivalence relation, we need to show that it is reflexive, symmetric, and transitive.
Since for every x in A there is a y in A such that x R y, we know that R is reflexive. This is because every element in A is related to itself by R, as given by the premise of the problem.
To show that R is symmetric, let x and y be arbitrary elements in A such that x R y. Since R is symmetric, we know that y R x. But since x R y, and R is transitive, it follows that x R x. Therefore, R is symmetric.
Finally, to show that R is transitive, let x, y, and z be arbitrary elements in A such that x R y and y R z. Since R is transitive, it follows that x R z. Therefore, R is transitive.
Since R is reflexive, symmetric, and transitive, it is an equivalence relation. We used direct proof technique to prove this.

a bridge hand consists of 13 cards dealt at random from the deck of 52. the probability that a bridge hand will have exactly 2 queens is:
The probability that a bridge hand will have exactly 2 queens is 0.45%.
To find the probability of getting a bridge hand with exactly 2 queens, we need to use the binomial probability formula. The formula is:
P(exactly k successes) = (n choose k) * p^k * (1-p)^(n-k)
Where:
n is the total number of trials
k is the number of successes in the trials
p is the probability of success in a single trial
In this case, the total number of trials is 13 (since a bridge hand consists of 13 cards), and the number of successes we want is 2 (since we want exactly 2 queens). The probability of success in a single trial is the probability of drawing a queen, which is 4/52 (since there are 4 queens in a deck of 52 cards).
Plugging these values into the formula, we get:
P(exactly 2 queens) = (13 choose 2) * (4/52)² * (48/52)¹¹
= (78) * (1/169) * (4/13)¹¹
= (4/169) * (4/13)¹¹
This simplifies to:
P(exactly 2 queens) = (4/169) * (4/13)¹¹
= (4/169) * (4/169)¹¹
= (4/169)¹²
The final probability is approximately 0.0045 or 0.45%. This means that the probability of getting a bridge hand with exactly 2 queens is quite low.

The following blank indicates a missing operation in the equation.
a deck of cards is dealt out. what is the probability that the 14th card dealt is an ace? what is the probability that the first ace occurs on the 14th card?
The probability of picking an ace on any draw is 4/52 or 1/13.
The probability that the 14th card dealt is an ace is 0.002641
We can first calculate the probability of not getting an ace on the first 13 draws, and then find the probability of getting an ace on the 14th draw:
P(No ace on 1st draw) = 48/52
P(No ace on 2nd draw) = 47/51
P(No ace on the 3rd draw) = 46/50
And so on...
P(No ace on the 13th draw) = 36/40.
P(Ace on 14th draw) = 4/39
To find the probability of these independent events, we multiply their probabilities:
P(Ace on 14th draw) = P(No ace in first 13 draws) x P(Ace on 14th draw)
P(Ace on 14th draw) = (48/52) x (47/51) x ... x (4/40) x (4/39)

If the wall requires two coats of paint, what is the minimum cost of painting Shayla's wall?
PLs answer and epxlain how you got it
Answer: $22
Step-by-step explanation:
The wall is 23 ft by 8 ft, so if you multiply both sides of the rectangle together, you get the area.
23 * 8 = 184 ft^2
Since the wall requires 2 coats of paint, that means you'll just need to double the area you need to cover (since you're covering it twice).
184 * 2 = 368 ft^2
Now that we know how much square feet of area we need to cover, we can try and figure out how many gallons of paint we need to cover said area.
One gallon of paint covers 320 ft^2, so we can divide the area we need to cover (368) by the area a single gallon can cover (320) to get the amount of gallons we need to cover the wall.
368 / 320 = 1.15 gallons
To cover the wall twice, we need 1.15 gallons of paint. Assuming we can't buy 0.15 of a gallon, we will just need to buy two full gallons. Each gallon is $11, so two gallons each costing $11 is:
2 * 11 = $22
Side note: IF you can buy 0.15 of a gallon, then just multiply 1.15 * 11 = $12.65
