What is equation?In mathematics, an equation is a proposition that states the equivalence of two expressions. An equation consists of two sides separated by a system of equations (=). For instance, the statement "2x + 3 = 9" states that the word "2x Plus 3" equals the integer "9". The goal of solving equations is to find the value or amounts of the variable in the model) that will permit the calculation to be accurate. Mathematics can be simple or complex, linear or nonlinear, and contain one or more parts. For example, in the equation "x2 + 2x - 3 = 0," the variable x is raised to the power of 2. Lines are used in many areas of mathematics, including algebra, arithmetic, and geometry.
We may begin by constructing an equation using the supplied formula and the party cost:
£12.50 multiplied by the number of children Equals £314.50
The equation can then be simplified by removing £27 from both sides:
£12.50 multiplied by the number of children Equals £287.50
Lastly, we can figure out how many children there are by dividing both sides by £12.50:
£287.50 x number of children = £12.50
total number of children = 23
As a result, the party had 23 children.

What is meant by Limacons, Cardioids etc. In Polar Form?
Limaçons, Cardioids, and other polar curves are curves described in polar form by their radial distance from the origin and the angle they make with a fixed reference line
In polar form, curves are described in terms of their radial distance from the origin and the angle they make with a fixed reference line.
Here are the definitions of some common polar curves:
Limaçons: A limaçon is a polar curve defined by the equation r = a + b cos(θ) or r = a + b sin(θ), where a and b are constants. The shape of the limaçon depends on the values of a and b. If a > b, the curve has a loop that encloses the origin; if a = b, the curve is a cardioid; and if a < b, the curve has a dimple that encloses the origin.
Cardioids: A cardioid is a special case of a limaçon where a = b. The equation of a cardioid is r = a + a cos(θ) or r = a + a sin(θ), where a is a constant. A cardioid looks like a heart-shaped curve.

Which of the following represents the intersection between 6x
-2 2-8 and 7x + 6 ≤ 13 ?
Answer:
The answer is x = 2/7
Step-by-step explanation:
To find the intersection between 6x - 2 and 2 - 8x, we need to solve the equation:
6x - 2 = 2 - 8x
Adding 8x to both sides, we get:
14x - 2 = 2
Adding 2 to both sides, we get:
14x = 4
Dividing both sides by 14, we get:
x = 4/14 = 2/7
To find the values of x that satisfy the inequality 7x + 6 ≤ 13, we need to solve the inequality:
7x + 6 ≤ 13
Subtracting 6 from both sides, we get:
7x ≤ 7
Dividing both sides by 7, we get:
x ≤ 1
Therefore, the intersection between 6x - 2 and 2 - 8x for values of x that satisfy 7x + 6 ≤ 13 is x = 2/7. Since 2/7 is less than or equal to 1, it satisfies the inequality.
So the answer is x = 2/7.

Step-by-step explanation:
Just a bit of a piecemeal.
2 rectangles and a half circle. We have all the dimensions.
1. Let's solve the big one first A = lw, putting in the numbers A = 4*15 = 60
2. The smaller one A = lw, putting int eh numbers A = 2 * 7 = 14
3. Now, the semi-circle. We know the diameter by deducting 12 from the total length, which is 9 + 7 = 16 in = 4 ft
The radius of the circle is half of the diameter, so the radius is 2 ft
The area of a circle is given by the formula A = πr^2, where A is the area and r is the radius.
Substituting the values, we get:
A = π(2)^2
A = 4π
The area of the circle is 4π square ft^2
Add: 60 + 14 + 4π = 74 + 4 π ft^2

Part A: Is X a binomial random variable? Explain. (3 points) Part B: What is the mean and standard deviation of X? Provide an interpretation for each value in context. (4 points) Part C: Two of the six customers receive the coupon with their purchase. Is the store's claim accurate? Compute P(X ≥ 2) and use the result to justify your answer. (3 points)
Part a: the success, with a probability of p = 1/5.
Part b:The mean of X is μ = np = 6(1/5) = 1.2.
Part c:The probability of at least two customers receiving the coupon can be computed using the binomial distribution formula, P(X ≥ 2) = 1 - P(X ≤ 1) = 1 - [tex](6C1)(1/5)^1(4/5)^5 - (6C0)(1/5)^0(4/5)^6[/tex]
Part A: Yes, X is a binomial random variable. A binomial random variable is the number of successes in a sequence of n independent trials, where each trial has a probability p of success. In this case, X is the number of customers that receive the 50% off coupon, which is the success, with a probability of p = 1/5. There are also a total of n = 6 independent trials, which is the number of customers that made purchases from the website.
Part B: The mean of X is μ = np = 6(1/5) = 1.2. This means that, on average, the store can expect 1.2 customers to receive the 50% off coupon. The standard deviation of X is σ = √(np(1 - p)) = √(6(1/5)(1 - 1/5)) = 0.9. This means that there is a large degree of variability in the number of customers that receive the 50% off coupon.
Part C: The store's claim is accurate. The probability of at least two customers receiving the coupon can be computed using the binomial distribution formula, P(X ≥ 2) = 1 - P(X ≤ 1) = 1 - [tex](6C1)(1/5)^1(4/5)^5 - (6C0)(1/5)^0(4/5)^6[/tex]

O D. 21 qt/wk
The equivalent rate measured in qt/wk is 5.25 qt/wk, which is closest to option C. 12 qt/wk.
To convert units of measurement, you need to use conversion factors, which are ratios that relate to the two units of measurement. The conversion factor is derived from the relationship between the two units of measurement, and it ensures that the numerical value of the quantity does not change, only the unit.
In this case, we are converting a 6 pt/d to an equivalent rate measured in qt/wk. We need to use conversion factors for both volume and time to do this.
First, we need to convert pints to quarts. Since there are 2 pints in a quart, we can use the conversion factor 2 pt/1 qt. Multiplying by this conversion factor gives:
6 pt/d x (1/8 qt/pt) x (7 d/wk) = 21/4 qt/wk = 5.25 qt/wkTherefore, the equivalent rate measured in qt/wk is 5.25 qt/wk, which is closest to option C. 12 qt/wk.

The balance of a certain loan increases at a rate that is proportional at any time to the balance at that time. The loan balance is $1600 initially, and it is $1920 after one year (365 days). What is the balance of the loan after 90 days?
By answering the presented question, we may conclude that As a result, proportionality the loan debt after 90 days is roughly $1713.17.
what is proportionality?Proportionate relationships are those that have the same ratio every time. For example, the average number of apples per tree defines how many trees are in an orchard and how many apples are in an apple harvest. Proportional refers to a linear relationship between two numbers or variables in mathematics. When the first quantity doubles, the second quantity doubles as well. When one of the variables decreases to 1/100th of its previous value, the other falls as well. When two quantities are proportional, it means that as one rises, the other rises as well, and the ratio between the two remains constant at all levels. The diameter and circumference of a circle serve as an example.
Let B represent the loan balance at any moment t. (t).
k * B d(B(t))/dt (t)
where k is a proportionality constant.
This differential equation may be solved by separating the variables.
k * dt = d(B(t))/B(t).
When both sides are combined, the following results:
B(t) ln(t) = k*t + C
where C is an integration constant.
ln(B(0)) = k*0 + C
ln(1600) = C
So,
[tex]k*t + ln(B(t)) = ln(B(t)) (1600)\\= k*1 + ln(B(1)) (1600)\\ln(1920) = k + ln (1600)\\k = ln(1920) - ln (1600)\\k = ln(1.2) (1.2)[/tex]
Therefore,
[tex]ln(B(t)) = ln(1600) * 1.2 * t\\1600 * 1.2t = ln(B(t))\\B(t) = 1600 * 1.2^t\\[/tex]
To calculate the loan balance after 90 days, enter t=90/365:
[tex]B(90/365) = 1600 * 1.2^(90/365)\\B(90/365) ≈ $1713.17\\[/tex]

What is An angle?A angle is geometric figure formed by two rays that share common endpoint called vertex. The two rays are called sides or legs of angle, and angle is typically denoted by vertex letter, with small arc between two sides to indicate angle.
Let's start by labeling the sides and angles:
/|
/ |
/ |
WX/___| Z
Y
WX is opposite to angle W
XY is adjacent to angle W
XZ is the hypotenuse of the triangle
Using the given information, we know that:
m∠W = 33°
XZ = WX / sin(W) (using the sine ratio)
We can solve for XZ as follows:
XZ = WX / sin(W)
XZ = XY / cos(W) (using the complementary angle of 90° - 33° = 57°)
We don't know the length of XY, but we can find it using the Pythagorean theorem:
XY² + WX² = XZ²
XY² + WX² = (WX / sin(W))²
XY² = (WX / sin(W))² - WX²
XY = sqrt((WX / sin(W))² - WX²)
Plugging in the given values, we get:
XY = sqrt((WX / sin(33°))² - WX²)
With WX rounded to the nearest tenth, we get:
WX = 16.8
XY = 28.5
XZ = 32.5

Intake valve opens (IVO) at 8 degrees before top dead center (BTDC)
Intake valve closes (IVC) at 50 degrees after bottom dead center (ABDC)
Exhaust valve opens (EVO) at 50 degrees before bottom dead center (BBDC)
Exhaust valve closes (EVC) at 8 degrees after top dead center (ATDC)
First, we need to determine the position of the piston at each of these valve events. We know that the stroke of the engine is 180 degrees, so we can use this information to calculate the position of the piston at each event:
IVO: piston is at 8 degrees BTDC
IVC: piston is at 180 - 50 = 130 degrees ATDC
EVO: piston is at 180 + 50 = 230 degrees ATDC
EVC: piston is at 360 - 8 = 352 degrees BTDC
To find the duration of the compression event, we need to calculate the number of degrees of crankshaft rotation between IVC and EVO. We can do this by subtracting the position of the piston at IVC from the position of the piston at EVO:
Duration of compression event = EVO - IVC
= 230 - 130
= 100 degrees
Therefore, the duration of the compression event is 100 degrees of crankshaft rotation.

The statement "the expression (213 + 55) ÷ 4 show how you could calculate the amount of money Ross has" is true. Dividing the total cost by 4 is the same as multiplying by 4. The correct answer is (c).
The expression (213 + 55) ÷ 4 represents the calculation of the total cost of the computer and software divided by four, which is the amount of money Ross has. The total cost of the computer and software is $213 + $55 = $268. Dividing $268 by 4 gives $67, which is a fourth of the total cost. Therefore, Ross has $67.
Dividing by 4 is the same as multiplying by 1/4. So, another way to write the expression is (213 + 55) × (1/4). Both expressions represent the same calculation and give the same result.
Therefore, option (c) is the correct answer, and the expression (213 + 55) ÷ 4 shows how to calculate the amount of money Ross has.

Answer:
orange box = [tex]1 \frac{1}{4}[/tex]
blue box = [tex]1\frac{3}{4}[/tex]
Step-by-step explanation:
We are counting up in quarters (1/4) so we add 1/4 (or a quarter) on every time.
1/4 + 1/4 = 2/4 = 1/2 (equivalent fractions)
2/4 + 1/4 = 3/4
3/4 + 1/4 = 4/4 = 1 whole = 1
1 + 1/4 = 1 1/4 = orange box
1 1/4 + 1/4 = 1 1/2 or 1 2/4
1 2/4 + 1/4 = 1 3/4 = blue box
