Solve the following: -7(1 - 8x) = 105

In order to know if a triangle is a right triangle on a coordinate plane, you can find the lengths of all three sides of the triangle using the distance formula and apply the Pythagorean theorem.

Find the lengths of the three sides of the triangle using the distance formula.

Once you have the lengths of the sides, check if any of the three sides satisfy the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the other two sides. In other words, if a² + b² = c², where c is the longest side, then the triangle is a right triangle.

If one of the sides satisfies the Pythagorean theorem, then the triangle is a right triangle.

Step-by-step explanation:

In summary, when a sample falls outside the control limits on an X-bar control chart, it signals a potential problem, and further investigation and corrective actions should be taken to identify and resolve the issue.

In an X-bar control chart, the upper control limit (UCL) and lower control limit (LCL) are set to monitor the process and detect any significant variations.

Given:

UCL = 0.65 inch

LCL = 0.35 inch

The next six samples are:

Sample 1: 0.60 inch

Sample 2: 0.37 inch

Sample 3: 0.45 inch

Sample 4: 0.48 inch

Sample 5: 0.53 inch

Sample 6: 0.62 inch

To determine what should be done, we need to check whether any of the samples fall outside the control limits.

Sample 1: 0.60 inch

Within control limits

Sample 2: 0.37 inch

Below the lower control limit (LCL)

Since Sample 2 falls below the lower control limit, it indicates a significant deviation from the expected process. This suggests that there might be an issue with the process or measurement.

Based on this result, the appropriate action would be to investigate the cause of the variation and take corrective measures to address the issue. It may involve analyzing the process, checking for any equipment malfunction, or reevaluating the measurement procedure.

All of the following are measures of central tendency except the range.

The range is a measure of dispersion, representing the difference between the largest and smallest values in a dataset. It provides information about the spread or variability of the data but does not provide information about the central tendency.

On the other hand, measures of central tendency are statistical measures that aim to summarize the center or typical value of a dataset. They include the mode, median, and mean.

The mode represents the most frequently occurring value(s) in the dataset.

The median is the middle value when the data is arranged in ascending or descending order. It divides the dataset into two equal halves.

The mean is the arithmetic average of all the values in the dataset. It is calculated by summing all the values and dividing by the total number of values.

Therefore, option C, range, is not a measure of central tendency as it focuses on the spread or dispersion of the data rather than summarizing the central or typical value.

For a unit circle, which has a radius as 1, we can derive the tangent values of all the degrees. With the help of a unit circle drawn on the XY plane, we can find out all the trigonometric ratios and values.

Answer:

C)Undefined

Not defined

Step-by-step explanation:

According to research ,

Tangent function denotes that for a given right-angled triangle, the tan of angleθ is equal to the ratio of the opposite side to the angle and adjacent side or base.

Tan θ = Opposite Side/Adjacent Side

We can also represent the tangent function as the ratio of the sine function and cosine function.

∴ Tan θ =Sin θ /Cos θ

So, tan 90 degrees in terms of ratio is,

Tan 90°=Sin 900 / Cos90°

From the trigonometric table, we know,

Sin 90° = 1

And,

Cos90° = 0

∴ Tan 90°= 1/0 = Undefined

That means, we cannot define Tan 900 value.

Notice that

(1 + x)(1 + y) = 1 + x + y + x y

So we can add 1 to both sides of both equations, and we use the property above to get

a + b + a b = 76  ==>  (1 + a)(1 + b) = 77

and

c + d + c d = 54  ==>  (1 + c)(1 + d) = 55

Now, 77 = 7*11 and 55 = 5*11, so we get

a + 1 = 7  ==>  a = 6

b + 1 = 11  ==>  b = 10

(or the other way around, since the given relations are symmetric)

and

c + 1 = 5  ==>  c = 4

d + 1 = 11  ==>  d = 10

Now substitute these values into the desired quantity:

The score that a student received if his/her score was the 98.71st percentile is 1265 by using the Z-score formula.

The Z-score formula is:
Z = (X - μ) / σ

Where Z is the Z-score, X is the raw score, μ is the population mean, and σ is the standard deviation. In this case, the Z-score for the 98.71st percentile is 2.15 (from Z-score table), the population mean is 1050, and the standard deviation is 100. We can plug these values into the formula and solve for X:

2.15 = (X - 1050) / 100
2.15 * 100 = X - 1050
215 = X - 1050
X = 1265

Therefore, the score that a student received if his/her score was the 98.71st percentile is 1265.

An ice cream shop has 10 flavors and one can choose 4 different flavors. The question asks for the total number of possible flavor combinations.Therefore, we need to find the number of ways in which 4 flavors can be chosen from 10 flavors.

In such cases where order does not matter and repetitions are not allowed, we can use the formula for combinations which is as follows:C(n, r) = n! / (r! (n - r)!)Where n is the total number of items, r is the number of items being chosen at a time and ! represents the factorial function.

Using this formula we can find the total number of possible flavor combinations. Substituting the values in the above formula, we get:C(10, 4) = 10! / (4! (10 - 4)!)C(10, 4) = (10 * 9 * 8 * 7) / (4 * 3 * 2 * 1)C(10, 4) = 210Hence, there are 210 possible flavor combinations when one can choose 4 different flavors

.Explanation:The formula to be used for this type of question is combination. Combination is the method of selecting objects from a set, typically without replacement (without putting the same item back into the set) and where order does not matter. The formula for combination is given by C(n,r)=n!/(r!(n-r)!).

The factored form of the polynomial is p(z) = (2z - 5)(z^(2) + 2z + 37).

To write the polynomial p(z) in factored form as a product of linear and quadratic expressions using integer coefficients only, we need to find the other zeros of the polynomial.

Since one of the zeros is a complex number, z = -1 + 6i, the other complex zero will be its conjugate, z = -1 - 6i. This is because complex zeros of polynomials with real coefficients always come in conjugate pairs.

Now, we can write the quadratic expression that has these two complex zeros as

(z - (-1 + 6i))(z - (-1 - 6i)) = (z + 1 - 6i)(z + 1 + 6i) = (z + 1)^(2) - (6i)^(2) = z^(2) + 2z + 1 - 36i^(2) = z^(2) + 2z + 37.

Since the polynomial p(z) is of degree 3, there must be one more zero, which we can find by dividing p(z) by the quadratic expression we just found:

p(z)/(z^(2) + 2z + 37) = 2z^(3)/(z^(2) + 2z + 37) - z^(2)/(z^(2) + 2z + 37) + 64z/(z^(2) + 2z + 37) - 185/(z^(2) + 2z + 37) = 2z - 5

So the other zero is z = 5/2.

Now,
p(z) = 2(z - 5/2)(z^(2) + 2z + 37) = (2z - 5)(z^(2) + 2z + 37)

So the factored form of the polynomial is p(z) = (2z - 5)(z^(2) + 2z + 37).

Step-by-step explanation:

First, let us clarify what (11, 0) represent

(x, y) ---> (11, 0)

The values are as followed:

x = 11

y = 0

If the problem states that x is the number of days after the promotion started, then it will be 11 days.

When we assert that it has been 11 days, we rule answers A and D.

If the problem states that y is the number of free coffee samples that remain after 11 days (because x is included in this statement), then it will be 0 samples.

Therefore, the answer will be C. After 11 days of the promotion, there will be 0 samples that are left.

To show that the origin is an unstable equilibrium, we need to find the eigenvalues of the Jacobian matrix evaluated at the origin. The Jacobian matrix is given by:

J = ⎡⎢⎣∂f1/∂x ∂f1/∂y∂f2/∂x ∂f2/∂y⎤⎥⎦

where f1 = 2y + x - (x^2 + 2y^2)x and f2 = -x + y - (x^2 + 2y^2)y. Evaluating the partial derivatives, we get:

J = ⎡⎢⎣-2x(x^2 + 2y^2) -4y(x^2 + 2y^2) -1 + 3x^2 + 2y^2 -1 + x^2 + 6y^2⎤⎥⎦

Evaluating J at the origin, we get:

J(0,0) = ⎡⎢⎣0 0 -1 -1⎤⎥⎦

To find the eigenvalues, we solve the characteristic equation:

det(J - λI) = 0

where I is the identity matrix. Solving, we get:

det(⎡⎢⎣-λ 0 -1 -1⎤⎥⎦) = λ^2 + 2λ = 0

The eigenvalues are λ = 0 and λ = -2. Since one eigenvalue is positive, the origin is an unstable equilibrium.

To show the existence of a periodic orbit, we can use a Lyapunov functional. Let V(x,y) = x^2 + y^2. Taking the time derivative of V, we get:

dV/dt = 2x(dx/dt) + 2y(dy/dt)

Substituting the given system equations, we get:

dV/dt = 2x(2y + x - (x^2 + 2y^2)x) + 2y(-x + y - (x^2 + 2y^2)y)

Simplifying, we get:

dV/dt = -2x^2 - 2y^2

Since dV/dt is negative definite, V(x,y) is a Lyapunov functional and there exists a periodic orbit.

Answer:

width = 9 inches , length = 12 inches

Step-by-step explanation:

let width be w then length = w + 3

area (A) of a rectangle is calculated as

A = length × width

  = (w + 3) × w = w(w + 3) = w² + 3w

given A = 108 , then

w² + 3w = 108 ( subtract 108 from both sides )

w² + 3w - 108 = 0 ← in standard form

(w + 12)(w - 9) = 0 ← in factored form

equate each factor to zero and solve for w

w + 12 = 0 ⇒ w = - 12

w - 9 = 0 ⇒ w = 9

however, w > 0 , so w = 9 and w + 3 = 9 + 3 = 12

then width = 9 inches and length = 12 inches
