There are 36 combinations and 181440 permutations

Explanation

The number of combinations of n object taking r at a time is given by the formula;

From the question, n = 9 and r = 7, then substitute these values into the formula

The number of permutations of n object taking r at a time is given by the formula;

Therefore, there are 36 combinations and 181440 permutations

The Values of (a+b)ab are undefined.

Given that, a = 3an and db = -2We need to find the values of (a+b)

Now, we have a = 3an... equation (1)Also, we have db = -2... equation (2)From equation (1), we get: n = 1/3... equation (3)Putting equation (3) in equation (1), we get: a = a/3a = 3... equation (4)Now, putting equation (4) in equation (1), we get: a = 3an... 3 = 3(1/3)n = 1

From equation (2), we have: db = -2=> d = -2/b... equation (5)Multiplying equation (1) and equation (2), we get: a*db = 3an * -2=> ab = -6n... equation (6)Putting values of n and a in equation (6), we get: ab = -6*1=> ab = -6... equation (7)Now, we need to find the value of (a+b).For this, we add equations (1) and (5),

we get a + d = 3an - 2/b=> a + (-2/b) = 3a(1) - 2/b=> a - 3a + 2/b = -2/b=> -2a + 2/b = -2/b=> -2a = 0=> a = 0From equation (1), we have a = 3an=> 0 = 3(1/3)n=> n = 0

Therefore, from equation (5), we have:d = -2/b=> 0 = -2/b=> b = ∞Now, we know that (a+b)ab = (0+∞)(0*∞) = undefined

Therefore, the values of (a+b)ab are undefined.

One way is to plot the complementary CDF 1 -CDF(x) on the logarithmic y scale. For exponentially distributed data, the result is a straight line.

The cumulative distribution function (CDF) maps a set of real numbers to a closed interval between 0 and 1. It must not decrease and must be bounded to zero as x→−∞ and to 1 as x→∞. (It must be right continuous, but we do not use that property in this answer.)

Claim: The cumulative distribution function cannot be a linear function over its domain.

Proof:

If the CDF is linear, the slope must be constant. This constant slope must be negative, zero, or positive. It can never be negative because it means the function is decreasing. This violates the first property that all CDFs must be non-decreasing.

A slope of zero means that the CDF is a constant function over its range, so it cannot be zero. For constants, x cannot be bound to both 0 and 1 as it approaches negative infinity and positive infinity respectively. (If one bound is satisfied, the other must be violated.)

Finally, it cannot be positive either. Assume that the slope is equal to ϵ>0. Now consider the value of the CDF (call it F) at x=0. For F(0) < 0, F is non-decreasing, so F(x) ≤ F(0) < 0 for all x < 0. But this means (if any) lim x→−∞F(x ) ≤. F is not a valid CDF because F(0)<0 and violates the required bounds.

From this we conclude that F(0)≥0 for a linear F.

Now consider F(2ϵ). If F is linear with slope ϵ>0 then F(2ϵ) = F(0)+ϵ⋅2ϵ  =F(0)+2 .But since F(0)≥0 we have F(2ϵ)≥2 . But if this is true, F(x)≥2 for all x>2ϵ, since F is non-decreasing. However, this result implies (if any) that lim x→∞F(x)≥2≠1. We also see that F cannot have a positive slope and satisfies one of the required limiting properties. From this we conclude that the slope can never be positive.

Having ruled out the possibility that the slope is negative, zero, or positive, we conclude that the function is not linear because the slope cannot have real values.

The CDF of each discrete random variable is piecewise linear, and the slope of each piece is zero. The continuous uniform distribution on the interval (θ1, θ2) is also piecewise linear, with one constant equal to zero, one constant equal to 1, and the "middle" part given by the formula F(x) = is represented. x− θ1θ2−θ1 .

We can also obtain the piecewise linear CDF as a mixture of discrete and uniform distributions.

The slope of the line that passes through the points (-9, 0) and (−17,4) is -2

The slope-intercept form of an equation is used whenever the equation of a line is expressed in the form y = mx + b. M represents the line's slope. B is the b in the location where the y-intercept is located (0, b). For instance, the slope and y-intercept of the equation y = 3x - 7 are 3 and 0, respectively.

The formula to calculate slope is -

m = x2 - x1 / y2 - y1

Step-by-step explanation:

In a right triangle, the Pythagorean theorem states that the square of the length of the side opposite the right angle (side AB) plus the square of the length of the side adjacent to the right angle (side BC) is equal to the square of the length of the hypotenuse (side AC).

In a right triangle, one of the angles is a right angle, which measures 90 degrees. Let's label the sides of the triangle as follows: AB is the side opposite to the right angle, BC is the side adjacent to the right angle, and AC is the hypotenuse, which is the side opposite to the remaining acute angle.

According to the Pythagorean theorem, in any right triangle, the sum of the squares of the lengths of the two shorter sides is equal to the square of the length of the hypotenuse. Mathematically, it can be expressed as:

A\(B^{2}\) + B\(C^{2}\) = A\(C^{2}\)

The local maximum is at (1, ) and the local minimum is at .

In the given graph, a local maximum occurs at the point (1, ). This means that at x = 1, the function reaches its highest value within a small neighborhood of that point. A local maximum is characterized by a peak in the graph, where the function changes from increasing to decreasing.

On the other hand, a local minimum represents the lowest point in a small region. However, the specific coordinates of the local minimum are not provided in the question. Without this information, it is not possible to identify the exact location of the local minimum on the graph.

To determine local maximum and minimum points, we analyze the behavior of the function around critical points, where the derivative is zero or undefined. By examining the intervals and the behavior of the function on either side of these critical points, we can identify the local extrema.

Answer:

length of the hypotenuse = √100 = 10 ft

Step-by-step explanation:

This is a right triangle with leg lengths 6 and 8 ft.  We apply the Pythagorean Theorem a^2 + b^2 = c^2, as follows:

(6 ft)^2 + (8 ft)^2  = c^2

Then c^2 = 100, and c = length of the hypotenuse = √100 = 10 ft

The probability that a 120 square foot roll will contain more than one flaw is approximately 0.0001, or 0.01%.

The number of flaws per square foot, denoted by X, as a Poisson distribution with parameter lambda = 1/40 (since there is an average of one flaw per 40 square feet).

To find the probability that a 120 square foot roll will contain more than one flaw, we need to calculate the probability of X > 1, where X is Poisson distributed with parameter lambda = 1/40.

Using the Poisson distribution formula, we have:

\(P(X > 1) = 1 - P(X < = 1)\)

= \(1 - [P(X = 0) + P(X = 1)]\)

We can calculate P(X = 0) and P(X = 1) using the Poisson distribution formula:

P(X = k) = (e^(-lambda) * lambda^k) / k!

where k is the number of flaws and lambda = 1/40.

\(P(X = 0) = (e^(-1/40) * (1/40)^0) / 0! = e^(-1/40) = 0.9756\)

\(P(X = 1) = (e^(-1/40) * (1/40)^1) / 1! = (1/40) * e^(-1/40) = 0.0244\)

\(P(X > 1) = 1 - [P(X = 0) + P(X = 1)]\)

\(= 1 - (0.9756 + 0.0244)\)

The range of the function g(x) = |x - 12| - 2 is {y | y > -2}, indicating that the function can take any value greater than -2.

To find the range of the function g(x) = |x - 12| - 2, we need to determine the set of all possible values that the function can take.

The absolute value function |x - 12| represents the distance between x and 12 on the number line. Since the absolute value always results in a non-negative value, the expression |x - 12| will always be greater than or equal to 0.

By subtracting 2 from |x - 12|, we shift the entire range downward by 2 units. This means that the minimum value of g(x) will be -2.

Therefore, the range of g(x) can be written as {y | y > -2}, which means that the function can take any value greater than -2. In other words, the range includes all real numbers greater than -2.

Visually, if we were to plot the graph of g(x), it would be a V-shaped graph with the vertex at (12, -2) and the arms extending upward infinitely. The function will never be less than -2 since we are subtracting 2 from the absolute value.
