Answer:

Probability ≈ 0.1071

Step-by-step explanation:

Consider steps below;

\(Total Possible Outcomes - 8C5,\\\\8! / 5! ( 8 - 5 )!,\\1 * 2 * 3 * 4 * 5 * 6 * 7 * 8 / ( 1 * 2 * 3 * 4 * 5 )( 1 * 2 * 3 ),\\\\6 * 7 * 8 / 6 = Combinations - 56,\\\\\)

\(Number Of Outcomes - 6C5,\\\\6! / 5! ( 6 - 5 )!,\\1 * 2 * 3 * 4 * 5 * 6 / ( 1 * 2 * 3 * 4 * 5 ) ( 1 ),\\720 / 120 * 1,\\\\Outcomes - 6\)

\(Conclusion ; Solution - 6 / 56 = ( About ) 0.1071\\Hope That Helps!\)

Solution; Probability ≈ 0.1071

The equatiion where C is the constant of integration.To evaluate the indefinite integral ∫(3e^x + 4x^5 - x^3/4 + 1)dx, we can integrate each term separately.

∫3e^x dx = 3∫e^x dx = 3e^x + C₁

∫4x^5 dx = 4∫x^5 dx = 4 * (1/6)x^6 + C₂ = (2/3)x^6 + C₂

∫-x^3/4 dx = (-1/4)∫x^3 dx = (-1/4) * (1/4)x^4 + C₃ = (-1/16)x^4 + C₃

∫1 dx = x + C₄

Now, we can combine these results to obtain the final answer:

∫(3e^x + 4x^5 - x^3/4 + 1)dx = 3e^x + (2/3)x^6 - (1/16)x^4 + x + C

Therefore, the indefinite integral of (3e^x + 4x^5 - x^3/4 + 1)dx is:

∫(3e^x + 4x^5 - x^3/4 + 1)dx = 3e^x + (2/3)x^6 - (1/16)x^4 + x + C

where C is the constant of integration.

Answer:

23,180 pieces

Explanation:

The number of white paper used = 13,480 pieces

Since they used 7,880 fewer pieces of blue paper than white paper

The number of blue paper used = 13,480 - 7880 =5,600 pieces

They also used 1,500 fewer pieces of yellow paper than blue paper.

The number of yellow paper used = 5,600-1500 =4100 pieces

Therefore. the total number of pieces of paper

=13,480 + 5,600 + 4100

=23,180 pieces

Answer: 36

Step-by-step explanation: If you're asking what the expression equals after plugging X's value in, this should leave you with an expression of -3^2 - 5(-3) + 12. By following the order of operations, you should receive an answer of 36.

Answer:

B.$1080

Step-by-step explanation:

her monthly income = $54,000 / 12 = $4,500

maximum monthly payment for debt services = $4,500 x 36% = $1,620

the closest amount without exceeding this good debt to income ratio rule is $1,080

generally speaking a good debt to income ratio = 36%, in other words, you should not spend more than 36% of your income paying loans. This "rule" is applied by banks along with the 28% rule for household expenses. Banks use the ²⁸/₃₆ rule when classifying clients. So, if you want to pay lower interest rates it is better if you do not spend more than 28% of your income in household expenses and 36% on debt service. The maximum debt to income ratio allowed in order to qualify for a Qualified Mortgage is 43%, but that is really pushing the banks' limits. It also depends on your total income, e.g. a person earning $1,000,000 per year can easily pay 43% in credit services, but it will be very difficult for someone earning $40,000.

Step-by-step explanation:

Simple

Total no of marbles = 6 + 4 + 8 = 18

Probability of red marble = 6 / 18 = 1/ 3

Since the percent grade in period 1 was 92% and in period 2 was 96%, then the percent change from period 1 to 2 was 4%.

Since the percent grade in period 2 was 96% and in period 3 was 99%, then the percent change from period 2 to 3 was 3%.

Since 4% is 1% greater than 3%, then the percent change from grading period 1 to 2 was 1% greater than the percent change from grading period 2 to 3.

Therefore, the answer is: 1.0%.

Answer:

a= x, b= 4

Step-by-step explanation:

Comparing polynomials:

Applying same formula:

X and Y are not independent

In order to answer this question, we need to refer back to Exercise 5.1.1, which defines the joint distribution of two random variables X and Y as:

P(X = 1, Y = 1) = 0.1
P(X = 1, Y = 2) = 0.2
P(X = 1.5, Y = 1) = 0.3
P(X = 1.5, Y = 2) = 0.4

a. To determine the conditional probability distribution of Y given that X = 1.5, we need to use the formula:

P(Y = y | X = 1.5) = P(X = 1.5, Y = y) / P(X = 1.5)

Using the joint distribution from Exercise 5.1.1, we can calculate the probabilities as follows:

P(Y = 1 | X = 1.5) = 0.3 / (0.3 + 0.4) = 0.4286
P(Y = 2 | X = 1.5) = 0.4 / (0.3 + 0.4) = 0.5714

Therefore, the conditional probability distribution of Y given that X = 1.5 is:

P(Y = 1 | X = 1.5) = 0.4286
P(Y = 2 | X = 1.5) = 0.5714

b. To determine the conditional probability distribution of X given that Y = 2, we use the same formula as above:

P(X = x | Y = 2) = P(X = x, Y = 2) / P(Y = 2)

Using the joint distribution from Exercise 5.1.1, we can calculate the probabilities as follows:

P(X = 1 | Y = 2) = 0.2 / (0.2 + 0.4) = 0.3333
P(X = 1.5 | Y = 2) = 0.4 / (0.2 + 0.4) = 0.6667

Therefore, the conditional probability distribution of X given that Y = 2 is:

P(X = 1 | Y = 2) = 0.3333
P(X = 1.5 | Y = 2) = 0.6667

c. To calculate E(Y | X = 1.5), we use the formula:

E(Y | X = 1.5) = ∑ y * P(Y = y | X = 1.5)

Using the conditional probability distribution of Y given that X = 1.5 from part a, we can calculate the expected value as follows:

E(Y | X = 1.5) = 1 * 0.4286 + 2 * 0.5714 = 1.714

Therefore, E(Y | X = 1.5) = 1.714.

d. To determine whether X and Y are independent, we need to check whether the joint distribution factors into the product of the marginal distributions:

P(X = x, Y = y) = P(X = x) * P(Y = y)

Using the joint distribution from Exercise 5.1.1, we can see that this condition does not hold, since for example:

P(X = 1.5, Y = 1) = 0.3
P(X = 1.5) * P(Y = 1) = 0.5 * 0.4 = 0.2

Therefore, X and Y are not independent.

The coordinates (2,1) will be on graph but (1,3) is not on graph.

What is a coordinate?

A coordinate is a set of two or more numbers or variables that identify the position of a point, line, or plane in a space of a given dimension. Coordinates are used to pinpoint a particular location, such as a specific point on a map or a specific point in a mathematical equation.

This means that for every 1.5 cups of dried fruit, there is 1 pound of granola. The graph of this proportional relationship would be a line that goes through the origin and has a slope of 1.5. For the point (2,1), the x-coordinate (2) is exactly 1.5 times the y-coordinate (1). This means that if you used 2 cups of dried fruit, you would get 1 pound of granola. Therefore, this point would be on the graph of the proportional relationship, so the answer is Yes. However, for the point (1,3), the x-coordinate (1) is not 1.5 times the y-coordinate (3). This means that if you used 1 cup of dried fruit, you would not get 3 pounds of granola.

The given problem involves evaluating various expressions involving complex numbers, trigonometric functions, and operations such as addition, subtraction, multiplication, and simplification. The expressions include trigonometric angles, complex conjugates, and principal values. The goal is to compute the values of these expressions based on the given inputs.

To evaluate the given expressions, we can use the properties and rules of complex numbers and trigonometric functions.

For the expression (i^2 + 1)^10, we simplify it by noting that i^2 equals -1. Therefore, (i^2 + 1)^10 becomes (−1 + 1)^10, which simplifies to 0^10 and results in 0.

For the expression sin90°, we know that the sine of 90 degrees is equal to 1.

For the expressions sin0°, cos0°, and cos180°, we can use the trigonometric identities to determine their values. The sine of 0 degrees is 0, the cosine of 0 degrees is 1, and the cosine of 180 degrees is -1.

To simplify the expression (1 + 1 + 1) / (2 + 1/3), we can perform the arithmetic operations inside the brackets first. This simplifies to 3 / (2 + 1/3). To rationalize the denominator, we multiply both the numerator and denominator by 3, resulting in 9 / (6 + 1). This simplifies to 9 / 7.

For the expression (1 - (1 - i) / (2i)) * (1 - (i / 1)), we simplify each fraction separately and then perform the multiplication. Simplifying the fractions gives

The relative frequency of heads is reasonably close to 40%.Mr. Clark's claim about the theoretical probability is likely to be false. This means that the theoretical probability of tails is most likely 0.60.

The relative frequency is the ratio of the number of times an event occurred to the total number of trials. In this case, the relative frequency of heads is 0.38 and tails is 0.62.The theoretical probability of an event is the number of favorable outcomes divided by the total number of possible outcomes.

Here, Mr. Clark claims that the coin is weighted so that the probability of heads is 40%. Therefore, the theoretical probability of heads is 0.40.However, the relative frequency of heads after 200 trials is only 0.38, which is reasonably close to 0.40. Hence, the relative frequency of heads is reasonably close to 40%.

Mr. Clark's claim about the theoretical probability of heads is likely to be false because the relative frequency of heads is less than the theoretical probability of heads (0.38 < 0.40).Therefore, the theoretical probability of tails is 1 - 0.40 = 0.60 because the coin is fair, so the probabilities of heads and tails should add up to 1. Thus, the theoretical probability of tails is most likely 0.60.

The value x in the secant line using the Intersecting btheorem is 19.

Intersecting secants theorem states that " If two secant line segments are drawn to a circle from an exterior point, then the product of the measures of one  of secant line segment and its external secant line segment is the same or equal to the product of the measures of the other secant line segment and its external line secant segment.

From the image;

External line segement of the first secant line = 8

First sectant line segment = ( x + 8 )

External line segement of the second secant line = 9

First sectant line segment = ( 15 + 9 )

Using the Intersecting secants theorem:

8 ×  ( x + 8 ) = 9 × ( 15 + 9 )

Solve for x:

8x + 64 = 135 + 81

8x + 64 = 216

8x = 216 - 64

8x = 152

x = 152/8

x = 19

Therefore, the value of x is 19.

If A and B are independent, then the correct statements are P(A and B) = 0.12 and P(A or B) = 0.58.

Let's evaluate each statement:

P(B/A) = 0.4:

This statement is incorrect. If events A and B are independent, the occurrence of event A does not affect the probability of event B.

Therefore, P(B/A) would still be equal to the probability of B, which is 0.4 in this case.

P(A and B) = 0.12:

This statement is correct. The probability of the intersection of independent events A and B is calculated by multiplying their individual probabilities. In this case, P(A and B) = P(A) * P(B) = 0.3 * 0.4 = 0.12.

P(A/B) = 0.3:

This statement is incorrect. If events A and B are independent, the occurrence of event B does not affect the probability of event A. Therefore, P(A/B) would still be equal to the probability of A, which is 0.3 in this case.

P(A or B) = 0.58:

This statement is incorrect. To calculate the probability of the union of two events, we need to consider whether the events are mutually exclusive or not.

If events A and B are independent, but not mutually exclusive, we can calculate P(A or B) as P(A) + P(B) - P(A and B). In this case, P(A or B) = 0.3 + 0.4 - 0.12 = 0.58.

Therefore, the correct statements are:

The statements regarding P(B/A) = 0.4 and P(A/B) = 0.3 are incorrect in the context of independent events A and B.
