what is compound interest?
Answers
Answer:
Compound interest is the addition of interest to the principal sum of a loan or deposit, or in other words, interest on interest. It is the result of reinvesting interest, rather than paying it out, so that interest in the next period is then earned on the principal sum plus previously accumulated interest.

This Quadrilateral is a trapezium. And the value of x is 13.
What is Quadrilateral?A quadrilateral is a clοsed figure and it have fοur sides, fοur vertices and fοur angles. In οrder tο create it, fοur nοn-cοllinear pοints are jοined. The sum οf interiοr angles οf quadrilaterals is always equal tο 360 degrees.
As two sides are parallel but not equal of a quadrilateral, it is conspired as trapezium.
Now, it is shown that the two adjacent angles are equal,
when two angles are qual it corresponding opposite side is equal too.
So,
30 = x + 17
Solving for x.
30 = x + 17
x = 30 - 17
x = 13
As x = 13
The longer side = x + 13 = 23 + 13 = 36

Using the variance concept, it is found that the correct option is:
B. must be at least zero
The mean of a data-set is the sum of all observations divided by the number of observations.The variance of a data-set is the sum of the differences squared between each term and the mean, divided by the number of values.Since the variance is squared, it's minimum value is 0, and thus, the correct option is:

suppose that you have a collection of n spins, each of which points up or down with equal probability. what is the probability that exactly n of them will point up? give both an exact expression and an approximation valid for large n. are there any additional conditions on n for your large n approximation to be valid?
Answers
For the normal approximation to be valid, the sample size should be at least 30, which means that n should be greater than or equal to 30.
Assuming that the probability that each spin points up or down is 0.5, and we have n spins, then the probability of exactly n of them pointing up is given by
P(n) = (n C n) * (0.5)^n = (0.5)^n, where (n C n) is the number of ways to choose n items out of n, which is simply 1.
If n is large, the probability can be approximated using the normal distribution with mean and variance given by
μ = np = n * 0.5σ² = np(1 - p) = n * 0.25T he probability can be approximated as:
P(n) ≈ N(μ, σ) = N(np, sqrt(np(1 - p))), where N is the normal distribution with mean np and variance np(1 - p). Additional conditions for the approximation to be valid:
Therefore, for the normal approximation to be valid, the sample size should be at least 30, which means that n should be greater than or equal to 30.

10) Determine whether the events of rolling a fair die two times are disjoint, independent, both, or neither. A) Disjoint. B) Exclusive. C) Independent. D) All of these. E) None of these.
Answers
The answer is option (C), that is, the events of rolling a fair die two times are independent. The events are neither disjoint nor exclusive.
When rolling a fair die two times, one can get any one of the 36 possible outcomes equally likely. Let A be the event of obtaining an even number on the first roll and let B be the event of getting a number greater than 3 on the second roll. Let’s see how the outcomes of A and B are related:
There are three even numbers on the die, i.e. A={2, 4, 6}. There are four numbers greater than 3 on the die, i.e. B={4, 5, 6}. So the intersection of A and B is the set {4, 6}, which is not empty. Thus, the events A and B are not disjoint. So option (A) is incorrect.
There is only one outcome that belongs to both A and B, i.e. the outcome of 6. Since there are 36 equally likely outcomes, the probability of the outcome 6 is 1/36. Now, if we know that the outcome of the first roll is an even number, does it affect the probability of getting a number greater than 3 on the second roll? Clearly not, since A∩B = {4, 6} and P(B|A) = P(A∩B)/P(A) = (2/36)/(18/36) = 1/9 = P(B). So the events A and B are independent. Thus, option (C) is correct. Neither option (A) nor option (C) can be correct, so we can eliminate options (D) and (E).

match each of the terms in the equation for raoult's law with the correct description. p1 = χ1 x p°1
Answers
Raoult's law equation, p1 = χ1 x p°1, relates the vapor pressure of a component in a solution to its mole fraction and the vapor pressure of the pure component.
In the equation p1 = χ1 x p°1, each term has a specific meaning:
p1 represents the vapor pressure of the component in the solution. Vapor pressure is the pressure exerted by the vapor phase when a substance is in equilibrium with its liquid phase at a given temperature.
χ1 is the mole fraction of the component in the solution. Mole fraction is a way to express the relative amount of a component in a mixture, defined as the ratio of the moles of the component to the total moles in the mixture.
p°1 refers to the vapor pressure of the pure component. It is the vapor pressure of the component when it is in its pure, undiluted state at the same temperature as the solution.
Raoult's law states that for an ideal solution, the vapor pressure of a component in a solution is directly proportional to its mole fraction in the solution and the vapor pressure of the pure component.
In other words, the partial pressure of a component in the vapor phase is equal to the mole fraction of that component multiplied by its vapor pressure in the pure state. This relationship assumes ideal behavior and is applicable for solutions where the intermolecular interactions between the components are similar.

The information which the line of best fit predict about the increase in the minimum wage over the 70 year period is that: C) Every 10 years between 1940 and 2010, the average increase in minimum wage was 0.096 dollars.
What is a line of best fit?In Mathematics, a line of best fit is sometimes referred to as a trend line and it can be defined as a statistical or analytical tool that is commonly used in conjunction with a scatter plot, in order to determine whether or not there is any form of association and correlation between a data set.
Based on the scatter plot, an equation which represents the line of best fit include the following:
y = 0.096x - 0.488.
In this context, we can logically deduce that the initial minimum wage is $0.488 and the average increase in minimum wage is equal to 0.096 dollars each year between 1940 and 2010.

The following steps/ procedure are to be taken when simplifying the expression.
open the parenthesis
(4 x − 3) − 2 (x + 5)

the length of a rectangle is 8 inches more than the width. if the length is increased by 4 inches and the width stays the same, the area increases by 24 sq inch. find the original dimensions of the rectangle
Answers
Let's assume that the width of the rectangle is "w" inches. According to the given information, the length of the rectangle is 8 inches more than the width, so the length can be represented as "w + 8" inches.
The original area of the rectangle is given by the product of the length and width:
Original area = (w + 8) * w
If the length is increased by 4 inches and the width remains the same, the new length becomes "w + 8 + 4 = w + 12" inches. The new area of the rectangle is given by:
New area = (w + 12) * w
According to the problem, the new area is 24 square inches greater than the original area. Therefore, we can set up the following equation:
New area - Original area = 24
[(w + 12) * w] - [(w + 8) * w] = 24
Expanding and simplifying the equation:
(w^2 + 12w) - (w^2 + 8w) = 24
w^2 + 12w - w^2 - 8w = 24
4w = 24
Dividing both sides of the equation by 4:
w = 6
So, the width of the original rectangle is 6 inches.
The length is 8 inches more than the width:
Length = 6 + 8 = 14 inches
Therefore, the original dimensions of the rectangle are 6 inches (width) and 14 inches (length).

the two non-parallel sides of an isosceles trapezoid are each 7 feet long. the longer of the 2 bases measures 22 feet. the sun of the base angles is 140 degrees.
Use the Law of Cosines to find the length of the diagonal.
Use the Law of Sines to find the length of the shorter base
Answers
Answer:
formula:
c^2 = a^2 + b^2 - 2abcos(C)
where c is the length of the diagonal, a and b are the lengths of the legs of the triangle (the non-parallel sides of the trapezoid), and C is the angle between them.
In this case, a = b = 7 feet and C = (180 - 140)/2 = 20 degrees. We can plug these values into the formula to find:
c^2 = 7^2 + 7^2 - 2(7)(7)cos(20)
c = sqrt(98 + 49cos(20))
To use the Law of Sines to find the length of the shorter base, we can use the following formula:
a/sin(A) = b/sin(B) = c/sin(C)
where a, b, and c are the sides of the triangle and A, B, and C are the angles opposite those sides.
Since we know a and b, we can use the formula to find:
x/sin(140) = 7/sin(20)
x = 7sin(140) / sin(20)
Note that the value of c will be in squared units, so you need to take the square root to get the actual length of the diagonal.
