The formula to add up all the terms in an arithmetic sequence is known as the sum of the arithmetic sequence.

An arithmetic series with finite arithmetic progress is produced, which is represented by (a, a + d, a + 2d,...), where "a" stands for the first term and "d" for the common difference.

Now, assume for an Arithmetic series (AP) where the common difference is "d" and the first term is "a".

Formula 1: When the value of the nth term in an arithmetic series is unknown, the sum of the first n terms is given by: \(S_{n} =\frac{n}{2}[2a+(n-1)d]\)

Formula 2: When the nth term in an arithmetic series is known, the sum of the first n terms is given by: \(S_{n} = \frac{n}{2}[a_{1} +a_{n} ]\)

In both the formulas, \(S_{n}\) = the sum of the arithmetic sequence.

Therefore this is meant by the sum of the arithmetic sequence.

Step-by-step explanation:

Let the unknown number be x

\(3 \times x + 3 = 24 \\ 3x + 3 = 24\)

Collect like terms and simplify

\(3x = 24 - 3 \\ 3x = 21\)

Divide both sides of the equation by 3

\( \frac{3x}{3} = \frac{21}{3} \)

Simplify

\(x = 7\)

Let's call the number we don't know n.

Since three times a number plus 3 is 24,

we can translate this to 3n + 3 = 24.

Solving from here, we subtract 3 from both sides to get 3n = 21.

Now we can divide both sides of the equation by 3 and we have n = 7.

So our number is 7.

Answer:

using the law of sines m<A is 36 approximately.

The probability of having one white ball is 1/20 or approximately 0.05.

To find the probability of selecting one white ball out of three balls, you need to know the number of white balls in the box and the total number of balls in the box. You also need to know whether the balls are being selected randomly or not.

Assuming that there is only one white ball in the box and the rest are some other color, and that the balls are being selected randomly.

The probability of selecting one white ball out of three would be:

Probability = (number of ways to select one white ball out of three) / (total number of ways to select three balls)

Since there is only one white ball, there is only one way to select one white ball out of three. The total number of ways to select three balls out of six is 6 choose 3, which is equal to 20.

Therefore, the probability of selecting one white ball out of three would be

Probability = (number of ways to select one white ball out of three) / (total number of ways to select three balls)

Probability = 1/20

Probability = approximately 0.05.

Answer:

Step-by-step explanation:

50 - 37 = 13 so the amount of books she needs is 13 to equal the total weight of 50 pounds

False. The expression \((3ab - 6a)^2\) is not the same as 2(3ab - 6a).

The expression\((3ab - 6a)^2\) is not the same as 2(3ab - 6a).

To simplify \((3ab - 6a)^2\), we need to apply the exponent of 2 to the entire expression. This means we have to multiply the expression by itself.

\((3ab - 6a)^2 = (3ab - 6a)(3ab - 6a)\)

Using the distributive property, we can expand this expression:

\((3ab - 6a)(3ab - 6a) = 9a^2b^2 - 18ab^2a + 18a^2b - 36a^2\)

Simplifying further, we can combine like terms:

\(9a^2b^2 - 18ab^2a + 18a^2b - 36a^2 = 9a^2b^2 - 18ab(a - 2b) + 18a^2b - 36a^2\)

The correct simplified form of \((3ab - 6a)^2 is 9a^2b^2 - 18ab(a - 2b) + 18a^2b - 36a^2\).

The statement that\((3ab - 6a)^2\) is the same as 2(3ab - 6a) is false.

Step-by-step explanation: no

a) To find the probability that x is 3 or less, we need to calculate P(x ≤ 3) using the binomial probability formula or a binomial probability table.

b) To find the probability that x is 3 or more, we can use the complement rule. P(x ≥ 3) = 1 - P(x < 3).

c) P(x < 3) is the same as P(x ≤ 2) since we are excluding 3. We can calculate it using the binomial probability formula or a binomial probability table.

d) P(x = 3) is the probability of getting exactly 3 successes in the sample, which can be calculated using the binomial probability formula.

a) To find the probability that x is 3 or less, we sum up the individual probabilities of getting 0, 1, 2, or 3 successes in the sample. This can be calculated using the binomial probability formula:

P(x ≤ 3) = P(x = 0) + P(x = 1) + P(x = 2) + P(x = 3)

b) To find the probability that x is 3 or more, we can use the complement rule. Since the complement of "x is 3 or more" is "x is less than 3," we can calculate P(x < 3) and then subtract it from 1:

P(x ≥ 3) = 1 - P(x < 3)

c) P(x < 3) is the probability of getting less than 3 successes in the sample. This includes the probabilities of getting 0, 1, or 2 successes:

P(x < 3) = P(x = 0) + P(x = 1) + P(x = 2)

d) P(x = 3) is the probability of getting exactly 3 successes in the sample. It is a specific outcome among all possible outcomes, so we calculate it directly using the binomial probability formula:

P(x = 3) = nCk * p^k * (1 - p)^(n - k)

Based on the data, the item that has the lowest price per pound is: B. peanuts, $1.60 per pound.

In Mathematics and Geometry, the rate of change (slope) of any straight line can be determined by using this mathematical equation;

Rate of change (slope) = (Change in y-axis, Δy)/(Change in x-axis, Δx)

Rate of change (slope) = rise/run

Rate of change (slope) = (y₂ - y₁)/(x₂ - x₁)

By substituting the given data points into the formula for the rate of change (slope) of a line, we have the following;

Rate of change (slope) of almonds = (y₂ - y₁)/(x₂ - x₁)

Rate of change (slope) of almonds = (32.40 - 13.50)/(12 - 5)

Rate of change (slope) of almonds = 18.9/7

Rate of change (slope) of almonds = $2.7

That a full cut round brilliant diamond with a 6.50 mm girdle diameter typically weighs around 1.00 carat.

carat weight is determined by a combination of a diamond's size and density. A diamond's size is measured by its diameter, which is the distance across the widest part of the diamond, known as the girdle. Therefore, a diamond with a larger girdle diameter will generally weigh more than a diamond with a smaller diameter, assuming all other factors are equal.

the weight of a diamond can be estimated based on its girdle diameter, and a full-cut round brilliant diamond with a 6.50 mm girdle diameter typically weighs around 1.00 carat. However, it's important to note that other factors, such as depth, cut, and clarity, can also affect a diamond's weight and value.

Step-by-step explanation:

Answer:94.5

Step-by-step explanation:

The division is one of the four fundamental arithmetic operations. The time it will take both of them together to paint the house is 6.857 hours.

The division is one of the four fundamental arithmetic operations, which tells us how the numbers are combined to form a new one.

Let the area that is needed to be painted be x.

Given that Walter can paint the house by himself in 12 hours. Therefore, we can write the rate at which Water paint is,

Rate = Area needed to be painted / Time

       = x / 12 hours

       = x/12

Further, given that Helen can paint the house by herself in 16 hours. Therefore, we can write the rate at which Helen paint is,

Rate = Area needed to be painted / Time

       = x / 16 hours

       = x/16

Now, the rate at which they both will paint or the area that they will cover in an hour is,

Rate = (x/12) + (x/16)

       = (4x/48) + (3x/48)

       = (4x + 3x)/48

       = 7x / 48

Furthermore, the time it will take both of them together to paint the house is,

Time = Area needed to be painted / Rate

        = x / (7x/48)

        = 48/7 hours

        = 6.857 hours

Hence, the time it will take both of them together to paint the house is 6.857 hours.

The component form of the vector that translates A to A' is (11, -17)

A translation is a type of transformation that takes each point in a figure and slides it the same distance in the same direction.

In translation, the shape of the figure does not change but its size may change.

Other transformation processes are reflection and rotation.

The component form of the vector is governed by the rule; A' - A

so we subtract corresponding x- coordinates and corresponding y- coordinates

A' - A = (7, -9) - (-4, 8)

       = ( 7 - - 4, -9 - 8)

The probability that no more than 5 cars will arrive in the next hour is approximately 0.744.

Let X be the number of cars that arrive at the drive-up window of the bank in an hour, and let λ be the average number of cars that arrive in an hour, which is 6.

       P(X ≤ 5) = ∑_{k=0}^{5} (e^(-λ) * λ^k) / k!

       where e is the mathematical constant approximately equal to 2.71828.

       P(X ≤ 5) = ∑_{k=0}^{5} (e^(-6) * 6^k) / k!

       P(X ≤ 5) = 0.744

Therefore, the probability that no more than 5 cars will arrive in the next hour is approximately 0.744.
