Answer: B. 43/76

\(\frac{1}{76}+x =\frac{11}{19}\\\\<=>x=\frac{11}{19}-\frac{1}{76}\\\\<=>x=\frac{43}{76}\)

Step-by-step explanation:

The position where where angle, θ would be located is at: angle F (∠F).

A right angle can be defined as a type of angle that is formed by the intersection of two (2) straight lines at 90 degrees. This ultimately implies that, a right angle has a measure of 90 degrees.

Additionally, all right angles are are formed as a linear pair and they are marked with a right angle symbol.

In conclusion, the measure of the angle in this right angle triangle would be calculated by using the tangent function as follows:

Tanθ = Opposite side/Adjacent side

Tanθ = 6/4

Angle, θ = tan⁻¹(6/4)

The distributive property is used when you have a value multiplied by 2 values separated by an operation.

For example, if you have x (y + z), then you would use the distributive property to get x (y + z) = xy + xz.

In the first row there are 7 chairs, and common difference is 2 implies that, the sequence in increasing order.

An ordered group of numbers with a shared difference between each succeeding word is known as an arithmetic sequence.

Given that,

The definition of the arithmetic sequence is given by,

an = a₁ + (n-1) d       (1)

Also, in first row, there are 7 chairs.

And after that row two more chairs are behind the first row.

Implies that, a₁ = 7 and d = 2.

Substitute this value in equation (1),

aₙ = 7 + (n - 1) 2

aₙ = 7 + 2n - 2

an = 5 + 2n

For the value of n the number of chairs can be found.

Hence, the arithmetic sequence is in increasing order.

The set of negative numbers greater than -40 but less than -28 is:

X = {-39, -38, -37, -36, -35, -34, -33, -32, -31, -30, -29}

Odd numbers are numbers that cannot be divided completely by 2 without a remainder.

Negative odd numbers are negative numbers that cannot be divided completely by 2 without any remainder

Let the set of odd numbers greater than -40 but less than -28 be represented by X

This can be written in set notation as:

X = {x | -40 < x < -28}

This means that the numbers range from -39 to -29

By listing, the set of negative numbers greater than -40 but less than -28 is:

Answer: 20 quarters

Step-by-step explanation:

As we look at this problem we can convert $6.50 dollars into 26 quarters. Us already knowing that Carolina has $1.50 (6 quarters) we can take the two numbers and minus both of them. 26 quarters ($6.50) - 6 quarters ($1.50) = 20 quarters($5.00)

Step-by-step explanation:

every $ is equivalent to 4 quarters.

every half-$ is equivalent to 2 quarters.

after all, 1 quarter = $0.25.

so, the equation is

4×1.5 + g = 4×6.5

or simplified

6 + g = 26

A high number of bins can produce noise and conceal the underlying pattern, whereas a small number of bins can oversimplify the distribution and obscure key characteristics equation  .

A mathematical equation is a process that links two statements and indicates equality using the equals sign (=). A mathematical statement that proves the equality of two mathematical expressions is known as an equation in algebra. For instance, the equal sign separates the numbers 3x + 5 and 14 in the equation 3x + 5 = 14. A mathematical formula may be used to understand the link between the two sentences that are written on opposite sides of a letter. Frequently, the logo and the particular software are identical. like in 2x - 4 = 2, for example.

The data and the goal of the display will determine the ideal number of bins for a histogram. The square root of the total number of data points can, however, be used to determine the number of bins as a general rule of thumb.

In this instance, the square root of 56 is around 7.5 and there are 56 bits of data. As a result, we may start with a range of 7-8 bins, which would provide the histogram a solid place to start.

It's crucial to remember that changing the number of bins might affect how the data should be interpreted. A high number of bins can produce noise and conceal the underlying pattern, whereas a small number of bins can oversimplify the distribution and obscure key characteristics.

the answer is: (7k−6)(4k²+7)

Answer:

Perimeter= 20 cm

Area = 25 cm^2

Difference between 28cm^2 and 8cm^2= 20cm^2

Step-by-step explanation:

The formula to calculate the perimeter of a square is P= 4 * (the length of any side or "s").

Therefore:

P = 4 * 5cm

P = 20 cm

The formula for calculating the area of a square is A= (length of any side or "s")^2

So:

A= 5cm^2

A= 25cm^2

Remember the units in your answer!

The difference between indicates subtraction, and 28cm^2 and 8 cm^2 are like terms so:

28cm^2 - 8 cm^2 = 20 cm^2

A stone arch can be twice as wide as a stone lintel because an arch distributes the weight of the structure vertically down its curve to the columns (piers) on either side while a lintel distributes the weight horizontally along the length of the stone.

A stone arch can be twice as wide as a stone lintel because an arch distributes the weight of the structure vertically down its curve to the columns (piers) on either side while a lintel distributes the weight horizontally along the length of the stone.

It requires only a small fraction of the arch's width to support itself while a lintel requires the full width of the structure that it spans. Thus, a stone arch can span a larger gap than a stone lintel and be twice as wide while using the same material.

For example, the Roman Colosseum uses an arch to span the entrances and exits while the walls supporting the upper levels use a series of stone lintels to support the structure.

Moreover, the arc prevents the need for a central support structure, which would be in the way of any events taking place in the structure. The technology of arches made them fundamental to ancient Roman architecture. For example, the arches were used to construct aqueducts, which provided a steady supply of water to the city of Rome.

The probability that at least one of 6 fair coins will land with tails facing up is 1 - (the probability that all 6 coins will land heads up).

The probability that a single coin will land heads up is 1/2, so the probability that all 6 coins will land heads up is (1/2)^6 = 1/64.

Therefore, the probability that at least one coin will land tails up is 1 - (1/64) = 63/64.

When subtracting a negative it becomes a positive

Answer:

Negative correlation.

Step-by-step explanation:

Negative correlation means that as x increases, y decreases

Positive correlation means that as x increases, y also increases.

No correlation means that neither of the two above cases happens.

In the graph, we can see that on the right (when x is negative) the general y values are larger.

As x increases, the y-values decrease.

(Particularly, we could adjust these data with a linear equation with a negative slope)

Then this is a negative correlation.

The probability of a random patient being alcoholic with elevated cholesterol levels is 55/80, or 0.6875. The probability of a random patient being nonalcoholic is 320/400, or 0.8. Lastly, the probability of a random patient being nonalcoholic with Non elevated cholesterol levels is 248/400, or 0.62.

To calculate the probability of a random patient being alcoholic with elevated cholesterol levels, we must first determine the total number of patients with elevated cholesterol levels. This can be done by adding the number of alcoholic patients (55) with elevated cholesterol levels to the number of nonalcoholic patients (72) with elevated cholesterol levels.

The result is a total of 127 patients with elevated cholesterol levels. This means that out of 400 patients, 55 of them were alcoholic and had elevated cholesterol levels. Therefore, the probability of a random patient being alcoholic with elevated cholesterol levels is 55/400, or 0.6875.

The probability of a random patient being nonalcoholic is equal to the total number of nonalcoholic patients (320) divided by the total number of patients (400). This yields a probability of 0.8.
