The multiplicative rule states that when two outcomes are independent, the probability that these outcomes occur together is the product of their probabilities.
What is the multiplicative rule?The multiplication rule is a method for calculating the likelihood of two events occurring at the same time (this is also one of the AP Statistics formulas). There are two rules for multiplication. P(A B) = P(A) P(B|A) is the general multiplication rule formula, while P(A B) is the specific multiplication rule (A and B).The multiplication rule is the multiplication of one event's probability by the likelihood of another occurrence. The law of independent assortment, Mendel's second law, stipulates that alleles of one gene segregate into gametes independently of alleles of another gene.Therefore, the multiplicative rule states that when two outcomes are independent, the probability that these outcomes occur together is the product of their probabilities.

What is the area of a triangle whose sides are 7 cm 24 cm and 25 cm?
Answer:
What is a area of a triangle ?Greek mathematician Heron of Alexandria was the first to determine the area of a triangle with three sides. Instead of using the triangle's side lengths, he provided a method that could compute a triangle's area without the need to measure any angles or other distances.
Let ABC be a triangle with lengths AB = c, BC = a, and CA = b for each of its three sides.
Triangle ABC's semi-perimeter is equal to s = (a + b + c)/2.
When the lengths of a triangle's three sides are known, the area of the triangle may be calculated using Heron's formula. To use this method, we must first determine the triangle's perimeter, which is the total distance around the triangle and is determined by summing the lengths of its three sides. There are two crucial phases in Heron's formula.
Add up the lengths of the triangle's three sides and divide the sum by two to determine its semi perimeter (half perimeter). In the primary formula known as "Heron's Formula," enter the triangle's semi-perimeter value.The semi perimeter of the triangle = 7 + 25 + 24 = 28 cm
By using Heron's formula

What is the main difference between 2D and 3D transform methods?
2D is "flat", using the horizontal and vertical (X and Y) dimensions, the image has only two dimensions and if turned to the side becomes a line. 3D adds the depth (Z) dimension. This third dimension allows for rotation and visualization from multiple perspectives.
2D transforms happen only on 2 or sometimes even 1 axis. For example if you are in a top orthographic view and rotate an object clockwise, you are usually only changing its rotation value in one axis (z axis in Blender, y in some other software).
In a perspective view, if you are able to use a gizmo to manipulate multiple axis you may be changing the rotation value on all three axes, this would be a 3D transformation.
You can shift an object on any of the three axis easily by grabbing the arrow and sliding the object, or you can move it to an entirely new set of coordinates, that's a 3D transformation.

The probability for event a is 0. 3, the probability for event b is 0. 6, and the probability of events a or b is 0. 8.
The events are not mutually exclusive because P(A or B) ≠ P(A) + P(B). The probability of either event happening is not equal to the sum of each event happening.
What are mutually exclusive events?Mutually exclusive events are events that cannot happen at the same time. For example, when you are tossing a coin, you cannot get head and tail at the same time. They are mutually exclusive, also called disjoint events, where P(A and B) = 0.
In mutually exclusive events, it also states that the probability of either event happening is the sum of probabilities of each event happening. It means that P(A or B) = P(A) + P(B).
Your question is incomplete and here is the complete question.
The probability for event A is 0.3, the probability for event B is 0.6, and the probability of events A or B is 0.8. Why are the events not mutually exclusive?
From the information, we have:
P(A) = 0.3P(B) = 0.6P(A or B) = 0.8Let's check if the events are mutually exclusive!
P(A or B) = P(A) + P(B)
P(A or B) = 0.3 + 0.6
P(A or B) = 0.9
0.8 ≠ 0.9
P(A or B) ≠ P(A) + P(B)
The probability of A or B is not equal to the sum of the individual probabilities. It proves that A and B are not mutually exclusive.
Hence, A and B are not mutually exclusive because the probability of A or B is not equal to the sum of the individual probabilities.

I need to find the rise over run
Calculate the rise between the two points and divide it by the difference in the horizontal direction to arrive at the answer (run).
How do you find the rise over run?An indication of how steep a line is is its slope. When calculating slope mathematically, "rise over run" is used (change in y divided by change in x). Calculate the rise over the run ratio of a line going through the points (-7,3) and (4, 2). With this in mind, the rise over run ratio of the line joining the two points is -1/11. Decide on the coordinates of two spots along the line.
Find the location of these two points' respective y-coordinate differences (rise). The difference between these two places' x-coordinates should be known (run). In order to calculate the difference in y-coordinates (rise/run or slope), divide it by the difference in x-coordinates. Rise is the quantity you gain or lose when moving from one location to another. That would result in a modification of the y values on the graph.

Give your anwer correct to one decimal place
The interest rate for the second and third years is 0.9%.
The interest rate for the second and third years is 0.9%.
We can use the formula for compound interest to find the value of x:
A = P(1 + r/n)^(nt)
Where:
A is the final amount (209754 yen)
P is the initial amount (200000 yen)
r is the interest rate (x% for the second and third years)
n is the number of times the interest is compounded per year (let's assume it is compounded annually)
t is the number of years the money is invested (3 years)
We know that the interest rate for the first year is 1.8%.
So we can calculate the final amount after the first year using:
A = P(1 + 1.8/100)^1
A = P(1.018)
A = 200000*(1.018) = 203600
So, the total amount after the first year is 203600 yen.
Now let's find the remaining interest rate for the second and third years:
A = P(1 + r/100)^(2)
203600 = 200000(1 + r/100)^2
We can now solve for the value of x by isolating r/100
r/100 = (203600/200000)^(1/2) - 1
x = (r/100)*100
x = (203600/200000)^(1/2) - 1*100
x = 0.9%
x is 0.9%
Hence, the interest rate for the second and third years is 0.9%.

Step-by-step explanation:
The ratio of apples to oranges is 4:3. For every 4 apples there are 3 organges. We can write that as 4A/3O, where A and O are Apples and Oranges. This can be rewritten as percentages of each fruit. A bag of 7 would have 4 Apples (4/7) or 0.5715 [57.15%] and 3 Oranges (3/7) or 0.4285 [42.85%].
A bag of 70(A and O) can be determined to have:
Apples: 70*(0.5715) = 40 Apples, and
Oranges: 70*(0.4285) = 30 Oranges
An account earned 5.4% interest compounded continuously. After 12 years the balance was
$1,433,785.18. What was the principal amount?
$762,775.54
O $748,999
$750,000
Answer:
To find the principal amount, you can use the formula for continuously compounded interest:
A = Pe^(rt)
where A is the final account balance, P is the initial principal (or starting) amount, r is the interest rate, and t is the time (in years) for which the interest is being calculated.
Substituting in the given values:
1,433,785.18 = P * e^(0.054 * 12)
To find P, we can divide both sides by e^(0.054 * 12)
P = 1,433,785.18 / e^(0.054 * 12)
In preparation of a company's annual dinner, 450 notebooks and 315 fridge stickers are to be

(a) Is it possible to prepare 21 goodie bags exactly? Explain your answer.
(b) What is the largest number of goodie bags that can be prepared?
(c) Using the answer from (b), how many notebooks and fridge stickers will there be in a goodie bag?
(a) To determine if it is possible to prepare 21 goodie bags exactly, we need to check if 450 notebooks and 315 fridge stickers can be divided equally into 21 goodie bags without any leftovers.
To do this, we can use the greatest common divisor (GCD) of 450 and 315, which is 15. If the GCD is not 1, it means that the two numbers cannot be divided exactly, so it is not possible to prepare exactly 21 goodie bags with 450 notebooks and 315 fridge stickers.
(b) To find the largest number of goodie bags that can be prepared, we can use the least common multiple (LCM) of 450 and 315. The LCM is 990, which means that 990 notebooks and 990 fridge stickers can be divided into the same number of goodie bags without any leftovers. Therefore, the largest number of goodie bags that can be prepared is 990/450 = 990/315 = 2.
(c) Using the answer from (b), we can calculate how many notebooks and fridge stickers will be in a goodie bag. If we divide 990 by 2, we get 495. Therefore, there will be 495 notebooks and 495 fridge stickers in each goodie bag.

The sum of the second and third terms of the arithmetic progression is equal to 0.
How to analyze arithmetic progressionsArithmetic progressions are sets whose terms are generated by expressions of the form:
y = a + r · (n - 1)
y = r · n + (a - r)
Where:
a - Value of the first term.r - Common raten - Index of the n-th term of the progression.
The sum of the second and third elements is:
n = 2
y = 2 · 2 - 5
y = - 1
n = 3
y = 2 · 3 - 5
y = 1
S = - 1 + 1
S = 0

Why do we calculate residuals?
The difference between the value predicted by the regression and the observed value for a given data point is known as the residual. The residual calculation offers a useful indicator of how well your model matches the given data set.
What is residual?The discrepancies between actual and expected data values are known as residuals in statistical or machine learning models.
They serve as a diagnostic tool for evaluating a model's quality. They are also called mistakes.
The table below's main column, Inflation, displays information on US inflation for each month of 2017. The Predicted column displays forecasts from a model that aims to forecast the pace of inflation.
The residuals are calculated as follows: Residual = Inflation - Predicted. They are displayed in the Residual column. In the instance of the data for January 2017, the model projected 1.8%, but the observed inflation was 0.5%, leaving a residual of -1.3%.
Hence, The residual calculation offers a useful indicator of how well your model matches the given data set.

If y varies directly as the square of x and y = -54 when x = 9, then y = -1 1/3 when x = 6
Therefore , the solution of the given problem of equation comes out to be k1 = - 0.67 and k2 = -0.1.
Describe equation.A mathematical equation is a formula that joins two statements and uses the equal symbol (=) to indicate equality. A scientific statement that verifies the equality of two formalisms is known as an equation in algebra. For instance, the pieces ptdc + 6 and 12 are separated by an equal sign in the solution obd + 6 = 12. The relationship between the two phrases on either flank of a letter is described by a mathematical formula. Often, there is only one variable, which also serves as the symbol. for instance, 4x – 4 = 0.
Here,
If y varies in this case simply also as square of x
k is the proportionality constant, and
y = kx² in mathematics.
Considering y = -54 and x = 9,
y = kx²
k = y/ x²
k = -54/ 9²
k = -54/81
k1 = - 0.67
Moreover, if y=-11/3 and x=6,
k = y/x²
k = -3.667/ (6)²
k = -3.667/36
k2 = -0.1

Find the measure of angles 1 and 2.
Explain your reasoning as to how you determined the measurements of angles 1 and 2.
Answer:
135 degrees
Step-by-step explanation:
You use Alternate interior angles to get angle 2, then vertical angles to find angle 1
Red is alternate interior angles
Yellow is vertical angles
Step-by-step explanation:
when a line intersects 2 or more parallel lines, it must have the same intersection angles with each of the parallel lines. otherwise the lines are not parallel after all, because parallel lines imitate each other's properties and behaviors exactly except for the actual location.
so,
angle 1 = 135°
the intersection angles between 2 lines must be the same in each side of each line, they are just left-right mirrored.
so,
angle 2 = angle 1 = 135°

. What is the total cost for the coat? Round to the nearest cent.
Answer:
The total amount that will be paid for the coat would be; $79.95 to the nearest cent.
Step-by-step explanation:
What is income tax?
Income tax is a tax applied on individuals or entities concerning income or profit earned by them.
Given that Jack wants to buy a coat that costs $74.95. The sales tax rate in his city is 6 and 1/2 percent.
Thus, the total cost for the coat can be calculated as;
The amount that will be paid for the coat will be;
= Amount of shirt + Tax
= $74.95 + (6.5% × $74.95)
= $74.95 + (6.5/100 × $74.95)
= $74.95 + $4.80
= $79.95
The total amount that will be paid for the coat would be; $79.95 to the nearest cent.
