By definition, theoretical probability is equal to:
A. No. of favorable outcomes/ total no. of possible outcomes ✅️
B. No. of total outcomes/ total no. of impossible outcomes
C. No. of possible outcomes/ total no. of favorable outcomes
D. No. of total outcomes/ total no. of possible outcomes
Theoretical probability is defined as the ratio of the number of favorable outcomes to the total number of possible outcomes, making option A the correct answer.
The correct answer is A. Theoretical probability is defined as the ratio of the number of favorable outcomes to the total number of possible outcomes. It represents the likelihood of an event occurring based on mathematical calculations and assumptions.
To provide a detailed explanation, let's break down the components of the definition:
Favorable outcomes: These are the outcomes that meet the desired criteria or event you are interested in. For example, if you are rolling a fair six-sided die and you want to find the probability of rolling a 3, the favorable outcome would be a single outcome where the die shows a 3.
Total number of possible outcomes: This refers to the complete set of all possible outcomes in the given situation. In the case of the fair six-sided die, there are six possible outcomes (numbers 1 to 6) since each face of the die represents a different number.
Theoretical probability is then calculated by dividing the number of favorable outcomes by the total number of possible outcomes. This ratio provides an estimate of the probability of the event occurring under ideal, theoretical conditions. It assumes that each outcome is equally likely to occur.
It's worth noting that theoretical probability is based on mathematical calculations and assumptions, and it may not always reflect the actual probability observed in real-world scenarios. However, it serves as a foundation for understanding and analyzing probabilities in various contexts, such as in mathematics, statistics, and decision-making processes.

E. 32% of people who prefer plan I are from the 36–45 age group, and 42% of people from the 46–55 age group prefer plan II.
The Percentage of people from the 46-55 age group preferring Plan II is 42%.
The percentages, we need to calculate the ratio of people preferring Plan I in the 36-45 age group and the ratio of people preferring Plan II in the 46-55 age group.
Let's start with the first part of the question:
Percentage of people preferring Plan I from the 36-45 age group:
To calculate this percentage, we need to divide the number of people preferring Plan I in the 36-45 age group by the total number of people preferring Plan I, and then multiply by 100 to express it as a percentage.
Number of people preferring Plan I in the 36-45 age group = 14
Total number of people preferring Plan I = 14 + 28 + 21 = 63
Percentage = (14 / 63) * 100 ≈ 22.22 ≈ 22% (rounded to the nearest whole number)
So, the percentage of people preferring Plan I from the 36-45 age group is approximately 22%.
Now, let's move on to the second part of the question:
Percentage of people from the 46-55 age group preferring Plan II:
To calculate this percentage, we need to divide the number of people preferring Plan II in the 46-55 age group by the total number of people from the 46-55 age group, and then multiply by 100 to express it as a percentage.
Number of people preferring Plan II in the 46-55 age group = 21
Total number of people in the 46-55 age group = 27 + 21 + 2 = 50
Percentage = (21 / 50) * 100 = 42%
So, the percentage of people from the 46-55 age group preferring Plan II is 42%.
Based on the calculations, the correct answer is:
A. 23% of people who prefer Plan I are from the 36-45 age group, and 42% of people from the 46-55 age group prefer Plan II.

Here, S.P. = . 1,61, 680 D%= 6%. M.P. = ?
The marked price (M.P.) is 1,72,000 when the selling price is 1,61,680 with discount of 6%.
To find the marked price (M.P.), we can use the formula:
M.P. = S.P. / (1 - D%)
Given:
S.P. = 1,61,680
D% = 6%
First, we need to convert the discount percentage to decimal form by dividing it by 100:
D% = 6/100 = 0.06
Now, we can substitute the values into the formula:
M.P. = 1,61,680 / (1 - 0.06)
M.P. = 1,61,680 / 0.94
M.P. = 1,72,000

an online store begins selling a new kind of baskelballshoe. At week zero, 30 pairs of shoes were sold.
In week 3, the store sold 240 pairs of shoes. Write an exponential model that relates the number of shoes sold to the week number, and use the model to predict how many shoes will be sold during week 7.
Answer:
3840 pairs of shoes
Step-by-step explanation:
To write an exponential model that relates the number of shoes sold to the week number, we can use the general form of an exponential function:
y = a * b^x
where:
y is the number of shoes sold,
x is the week number, and
a and b are constants to be determined.
Given the information:
In week 0, 30 pairs of shoes were sold.
In week 3, 240 pairs of shoes were sold.
We can use these two data points to determine the values of a and b.
Using the data point for week 0:
30 = a * b^0
30 = a
Using the data point for week 3:
240 = 30 * b^3
8 = b^3
b = 2 (taking the cube root of both sides)
Therefore, the exponential model that relates the number of shoes sold to the week number is:
y = 30 * 2^x
To predict the number of shoes sold during week 7, we substitute x = 7 into the model:
y = 30 * 2^7
y = 30 * 128
y = 3840
Therefore, the model predicts that 3840 pairs of shoes will be sold during week 7.

What is the MACRS depreciation schedule?The depreciation schedule using the Modified Accelerated Cost Recovery System (MACRS) is prepared as follows:
Given data:
Purchase cost of the metal-working lathe: $38,000
Business use percentage: 90%
Section 179 deduction: $18,000
Special depreciation allowance: 50%
Depreciable basis = Purchase cost - Section 179 deduction
Depreciable basis = $38,000 - $18,000 = $20,000
Special depreciation allowance = $20,000 * 50%
Special depreciation allowance = $10,000
Adjusted depreciable basis = $20,000 - $10,000
Adjusted depreciable basis = $10,000

Answer:
Is 03.841
Step-by-step explanation:
To find the critical value needed to test the claim that the sentence is independent of the plea, we need to perform a chi-square test of independence. The critical value is based on the significance level (α) and the degrees of freedom.
In this case, the given significance level is 0.05. Since the table represents a 2x2 contingency table (two categories for plea and two categories for sentence), the degrees of freedom (df) can be calculated as (number of rows - 1) * (number of columns - 1) = (2 - 1) * (2 - 1) = 1.
To find the critical value at a significance level of 0.05 with 1 degree of freedom, we consult a chi-square distribution table or use statistical software.
The critical value for a chi-square test with 1 degree of freedom and a significance level of 0.05 is approximately 3.841.
Therefore, the correct answer is 03.841.

Triangle FGH is inscribed in circle O, the length of radius OH is 6, and maFGH-20. What is the area of the sector formed by angle FOH, in terms of pi 1) 2k 2) 3/2 (3) 4
PLEASE HELP ME, NO FAKE ANSWERS (sorry that it's blurry)
Triangle FGH is inscribed in circle O, the length of radius OH is 6, and ma FGH-20. The area of the sector formed by angle FOH, in terms of pi is 6π. Hence, it is neither of the options.
Given that triangle FGH is inscribed in circle O, the length of radius OH is 6, and m∠FGH = 20.
We have to find the area of the sector formed by angle FOH, in terms of pi.
Using the central angle, we know that the measure of ∠FOH is twice that of ∠FGH, which is 40°.
Therefore, the measure of the central angle FOH is 2 * 40 = 80°.
The area of the sector formed by angle FOH, in terms of pi is given by, A = r²θ/2 where A = Area of the sector, r = radius of the circle and θ = central angle in radians.
To calculate the value of A in terms of pi, we have to convert the central angle from degrees to radians.
1 radian = 180°/π radians
Therefore, 80° = 80° * (π/180°) = 4π/9 radians.
Now we can plug in the given values of r and θ to find the area of the sector.
A = (6)² * (4π/9) / 2 = 18π/3 = 6π
Thus, the area of the sector formed by angle FOH, in terms of pi is 6π.
Hence, option 1) 2k is incorrect. Option 2) 3/2 (3) is incorrect. Option 3) 4 is incorrect. Answer: 6π.

A passenger train leaves depot 2 hours after a freight train leaves the same depot. The freight train is traveling 18 mph slower than the freight train find the rate of each train if the passenger train over, takes the freight train in 3 hours
Answer:
The passenger train is traveling at 45 mph, and the freight train is traveling at 27 mph.
Step-by-step explanation:
Let's assume the speed of the passenger train is represented by x mph.
According to the given information, the freight train leaves the depot 2 hours before the passenger train. Therefore, when the passenger train starts, the freight train has already been traveling for 2 hours.
Let's represent the speed of the freight train as (x - 18) mph, which is 18 mph slower than the passenger train.
Now, we know that the passenger train overtakes the freight train in 3 hours. This means that the passenger train traveled for 3 hours, while the freight train traveled for 3 + 2 = 5 hours.
Since speed = distance/time, we can set up the following equation based on the distances covered by each train:
Distance covered by passenger train = Distance covered by freight train
Using the formula, distance = speed × time, we get:
x × 3 = (x - 18) × 5
Simplifying the equation:
3x = 5x - 90
90 = 5x - 3x
90 = 2x
Dividing both sides by 2:
45 = x
So, the speed of the passenger train is 45 mph.
The speed of the freight train is 45 - 18 = 27 mph.

Total Surface Area of the Triangular prism = 30 ft².
Here, we have,
The triangular prism is attached.
The triangular prism shown has 2 triangular faces and 3 lateral faces.
here, we have,
Base of the triangle =2 ft
Height of the Triangle =3 ft
Area of one Triangular Face is:
A = 1/2 * 2 * 3 = 3 ft²
The dimensions of the lateral rectangles are:
2 ft by 3 ft
3 ft by height 3 ft
3 ft by height 3 ft
Therefore, total surface area of the triangular prism
=2(Area of one Triangular Face)+Area of 3 rectangular faces
= 2 *3 + ( 2*3 + 3*3 + 3*3)
= 6 + 24
= 30 ft²

O+O+O=30
1-3 -5 -7
9 -11 -
15
To solve the equations:
O + O + O = 30
1 - 3 - 5 - 7
9 - 11 -
15
We can start by simplifying the second equation:
1 - 3 - 5 - 7 = -14
9 - 11 - x = -14
To find the value of x, we can solve the equation:
-11 - x = -14
Adding 11 to both sides of the equation:
-11 + 11 - x = -14 + 11
Simplifying:
-x = -3
Multiplying both sides by -1:
(-1) * (-x) = (-1) * (-3)
x = 3
Now, substituting the value of x back into the second equation:
9 - 11 - 3 = -14
-5 - 3 = -14
-8 = -14
This is not a true statement. Therefore, the values provided do not satisfy the equations given.
