The distribution f(x; 7, 0) is in the two-parameter exponential family, and the binomial distribution arises when θ = 1.

To show that the discrete distribution function f(x; 7, 0) is in the two-parameter exponential family, we need to express it in the form:

f(x; 7, 0) = h(x, 7, 0) * exp{ θT(x) - A(θ) },

where:

h(x, 7, 0) is the base measure,

θ is the natural parameter,

θT(x) is the sufficient statistic,

A(θ) is the log partition function.

Let's start by expressing f(x; 7, 0) in terms of its parameters:

f(x; 7, 0) = c(7, 0) * (7C0)^(1-θ) * (θ^x) * ((1-θ)^(n-x))

We can rewrite this as:

f(x; 7, 0) = [c(7, 0) * (7C0)^(1-θ)] * [θ^x * (1-θ)^(n-x)]

Comparing this with the form of the exponential family, we can identify:

h(x, 7, 0) = 1 (since there is no multiplicative factor dependent on x)

θ = θ (the natural parameter)

θT(x) = x (the sufficient statistic)

A(θ) = -log[c(7, 0) * (7C0)^(1-θ)] (the log partition function)

Now, let's consider the case when θ = 1. When θ = 1, the distribution function becomes:

f(x; 7, 0) = c(7, 0) * (7C0)^0 * (1^x) * (0^(n-x))

Simplifying this, we have:

f(x; 7, 0) = c(7, 0) * 1 * 1 * 0^(n-x) = c(7, 0) * 0^(n-x) = c(7, 0) * 0

In the case where θ = 1, the probability mass function collapses to a constant value (0 in this case), indicating that the binomial distribution occurs.

Hence, when θ = 1, we have:

f(x; 7, 0) = c(7, 0) * 0

This demonstrates that the binomial distribution is a special case of the discrete distribution f(x; 7, 0) when θ = 1.

Overall, the distribution f(x; 7, 0) is in the two-parameter exponential family, and the binomial distribution arises when θ = 1.

The solution to the linear system is unique solution which is  x₁ = 1/6, x₂ = 3/2, and x₃ = 17/6.

The correct answer is option  A.

To solve the given system of linear equations using elementary row operations and back substitution, let's start by representing the augmented coefficient matrix:

[1  -4  5  |  23]

[2   1   1  |  10]

[-3  2  -3 |  -23]

We'll apply row operations to transform this matrix into echelon form:

1. Multiply Row 2 by -2 and add it to Row 1:

[1  -4   5   |  23]

[0   9   -9  |  -6]

[-3  2  -3  |  -23]

2. Multiply Row 3 by 3 and add it to Row 1:

[1  -4  5   |  23]

[0   9  -9  |  -6]

[0   -10 6  |  -68]

3. Multiply Row 2 by 10/9:

[1  -4  5    |  23]

[0   1   -1   |  -2/3]

[0   -10 6  |  -68]

4. Multiply Row 2 by 4 and add it to Row 1:

[1  0   1   |  5/3]

[0  1   -1  |  -2/3]

[0  -10 6  |  -68]

5. Multiply Row 2 by 10 and add it to Row 3:

[1  0   1   |  5/3]

[0  1   -1  |  -2/3]

[0  0   -4  |  -34/3]

Now, we have the augmented coefficient matrix in echelon form. Let's solve the system using back substitution:

From Row 3, we can deduce that -4x₃ = -34/3, which simplifies to x₃ = 34/12 = 17/6.

From Row 2, we can substitute the value of x₃ and find that x₂ - x₃ = -2/3, which becomes x₂ - (17/6) = -2/3. Simplifying, we get x₂ = 17/6 - 2/3 = 9/6 = 3/2.

From Row 1, we can substitute the values of x₂ and x₃ and find that x₁ + x₂ = 5/3, which becomes x₁ + 3/2 = 5/3. Simplifying, we get x₁ = 5/3 - 3/2 = 10/6 - 9/6 = 1/6.

What is probabilty ?

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics. The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events. The degree to which something is likely to happen is basically what probability means. You will understand the potential outcomes for a random experiment using this fundamental theory of probability, which is also applied to the probability distribution. Knowing the total number of outcomes is necessary before we can calculate the likelihood that a specific event will occur.

We have,

n = 4000

p = 0.35 , q=1-p=0.65

= E(X) = np= 4000 (0.35) 600 1400

6 = SE(X) = √npq √ 4000 (0-35)(0.65) = 30.1662

Consider

P(X\(\geq\)1450) = p 7

X-U

1450 1400

30.1662

=P(z>1,66)

=0.048457

Hence, 4.845% chance that 1,450 or more of the voters with annual incomes above $50,000 will be polled

Answer:

Arc length MK = 15.45 units (nearest hundredth)

Arc measure = 58.24°

Step-by-step explanation:

Calculate the measure of the angle KLN (as this equals m∠KLM which is the measure of arc MK)

ΔKNL is a right triangle, so we can use the cos trig ratio to find ∠KLM:

\(\sf \cos(\theta)=\dfrac{A}{H}\)

where:

Given:

\(\implies \sf \cos(KLM)=\dfrac{8}{15.2}\)

\(\implies \sf \angle KLM=\cos^{-1}\left(\dfrac{8}{15.2}\right)\)

\(\implies \sf \angle KLM=58.24313614^{\circ}\)

Therefore, the measure of arc MK = 58.24° (nearest hundredth)

\(\textsf{Arc length}=2 \pi r\left(\dfrac{\theta}{360^{\circ}}\right) \quad \textsf{(where r is the radius and}\:\theta\:{\textsf{is the angle)}\)

Given:

\(\implies \textsf{Arc length MK}=2 \pi (15.2)\left(\dfrac{\sf \angle KLM}{360^{\circ}}\right)\)

\(\implies \textsf{Arc length MK}=\sf 15.45132428\:units\)

Answer:

x > 12

Step-by-step explanation:

\(\frac{1}{3}\)(x - 6) > 2

\(\frac{1}{3}\)x - 2 > 2

\(\frac{1}{3}\)x > 4

\(\frac{1}{3}\)x * 3 > 4 * 3

x > 12

Answer:

X < 12

Step-by-step explanation:

48+140=188

92+210=302

if you at all it equals 490

5x + 25 + x + 5 = 90

6x + 30 = 90

6x = 90 - 30

6x = 60

x = 10

Solution:

We can see that the 90° angle is divided into two angles. Thus, the sum of two angles must equal 90°.

Combine like terms:

Subtract 30 both sides:

Divide 6 both sides:

The value of x is 10.

Let's denote the ages of the two remaining men as x and x + 3 (since one is 3 years older than the other).

We know that the average age of 6 men is 35 years. So, the sum of their ages is 6 * 35 = 210 years.

We also know that the average age of four of them is 32 years. So, the sum of their ages is 4 * 32 = 128 years.

To find the sum of the ages of the two remaining men, we subtract the sum of the ages of the four men from the sum of the ages of all six men:

210 - 128 = 82 years.

Now, we can set up an equation to solve for the ages of the remaining two men:

x + (x + 3) = 82.

Combining like terms, we get:

2x + 3 = 82.

Subtracting 3 from both sides:

2x = 79.

Dividing both sides by 2:

x = 39.5.

So, one of the remaining men is 39.5 years old, and the other is 39.5 + 3 = 42.5 years old.

The dimension of the sidewalk is length 29.8 cm and the height 31.8 cm.

Given,

The side of square base of pyramid x.

Height 2 centimeters greater than the length of each side of its square base=x+2

Volume of pyramid=297cubic cm

We have to calculate the dimensions

Volume=1/3 a²h

a is the side length.

h is height of pyramid.

297=x²(x+2)/3

891=x³+2x²

891=x²(x+2)

x²=891, x+2=891

x=29.8, x+2=891,x=889

Hence length of base the pyramid is 29.8 cm and height is 31.8cm

The IQR would remain unaffected.

The Standard deviation  is a measure of how much the individual values in a data set differ from the mean. The formula to calculate the standard deviation is:

SD = √(∑(x-mean)2/n)

Where, x = an individual value in the data set, n = total number of values in the data set and mean = average of the data set.

In the given data set, with the electric car being removed, the total number of values in the data set would reduce from 67 to 66. Therefore, the standard deviation would be calculated using the formula with 66 in place of n.

The interquartile range (IQR) is the difference between the third quartile and the first quartile. The formula to calculate the IQR is:

We are looking for a factor that, when paired with 15, has an ICM (Least Common Multiple) of 15.

The ICM of two numbers is the smallest positive integer that is divisible by both numbers.

Let's calculate the ICM for each factor of 40 when paired with 15:

ICM(1, 15) = 15

ICM(2, 15) = 30

ICM(4, 15) = 60

ICM(5, 15) = 15

ICM(8, 15) = 120

ICM(10, 15) = 30

ICM(20, 15) = 60

ICM(40, 15) = 120

From the calculations, we can see that the pair (1, 15) and the pair (5, 15) have an ICM of 15.

However, since you mentioned that the factor is not 1, the factor we are looking for is 5. When paired with 15, the ICM is indeed 15.

The question is about a number that is a factor of 40 and not equal to 1. When this number is paired with 15, their ICM is 15. We need to find this number.

Here, we need to find a number that is a factor of 40 and not equal to 1 such that the ICM (least common multiple) of this number and 15 is 15.

Let's write the prime factorization of 40:

40 = 2 × 2 × 2 × 5

Hence, the factors of 40 are: 1, 2, 4, 5, 8, 10, 20, and 40.

To find out which of these factors can be paired with 15 to give an ICM of 15,

we need to find the prime factorization of 15:15 = 3 × 5

The LCM of 15 and any other number will contain the highest power of each prime factor present in either of the two numbers.

So, LCM (15, x) will contain 3 and 5 at least once each.

Since LCM (15, x) = 15, we need to find a factor of 40 that contains the remaining factors of 15 (apart from 3 and 5), which is 3.

Since 3 is not a factor of 40, there is no such number that can be paired with 15 to give an ICM of 15.

Hence, the answer is that there is no such number.
