Answer:

Given;

120,000 people voted in 2015.

In 2015, 20% more people voted than 2014.

Therefore:

How many more people voted in 2015 = 20% of 120,000

= 24,000

Total number of people voted in 2014 = 120,000 - 24,000

= 96,000

Ans) 96,000 people voted in 2014.

The correct statement regarding the exponential functions g(x) and h(x) is given as follows:

B g( x) ≥ h( x) on the interval –2 ≤ x ≤ 2.

The standard definition of an exponential function is given as follows:

y = ab^x.

In which the coefficients of the function are described as follows:

Function h(x) is defined as follows:

h(x) = 3^x - 2.

For the graphed function g(x), when x = 0, y = 4, hence the intercept of the function is given as follows:

a = 4.

When x = 1, y = 5, hence the rate of change of the function is obtained as follows:

b = 5/4.

b = 1.25.

Then function g(x) is given as follows:

g(x) = 4(1.25)^x.

Due to the higher intercept, g(x) ≥ h( x) at x = 0. This will change when they intersect, which from the image given at the end of the answer is at x = 1.906, which is approximately 2, hence statement B is correct.

The independent set in a graph is a set of vertices that contain no edges. So, no neighboring vertices are included. The max independent set problem is to get an independent set of maximum size in graph G.

The solution for this question is discussed below:

a) The integer linear program for the max independent set problem is as follows:

maximize ∑x_i Subject to: x_i+x_j ≤ 1 {i,j} ∈ E;x_i ∈ {0, 1} ∀i. The variable x_i can represent whether the ith vertex is in the independent set. It can take on two values, either 0 or 1.

b) The LP relaxation for the max independent set problem is as follows:

Maximize ∑x_iSubject to:

xi+xj ≤ 1 ∀ {i, j} ∈ E;xi ≥ 0 ∀i. The variable xi can take on fractional values in the LP relaxation.

c) The family of graphs is as follows:

Consider a family of graphs G = (V, E) defined as follows. The vertex set V has n = 2^k vertices, where k is a positive integer. The set of edges E is defined as {uv:u, v ∈ {0, 1}^k and u≠v and u, v differ in precisely one coordinate}. It can be shown that the size of the max independent set is n/2. Using LP, the value can be determined. LP provides a value of approximately n/4. Therefore, the ratio LP-OPT/OPT is at least c/4. Therefore, the ratio is in for a constant c>0.

d) The size of a max-independent set is equivalent to the number of vertices minus the minimum vertex cover size.

e) The 2-approximation algorithm for vertex cover implies a 2-approximation algorithm for the max independent set.

The value of mean is 59.8 and the variance of the sampling distribution is 1440.46

Given,

In the question:

The distance X is measured in miles and the sampling distribution of X is given by;

X :-      0        10    50     100

P(X) : - 1 /12    1/6   1/3    5/12

Calculate the mean and variance of this sampling distribution.

Now, According to the question:

The variance of a random variable provides an idea of the dispersion of the random variable with respect to its hope. It is then defined as shown in the image.

Then you first calculate E [x] and E [\(x^{2}\)], and then be able to calculate the variance.

E[x] = 0 × 1/12 + 10 × 1/6 + 50 × 1/3 + 100 × 5/12

E[x] = 1.6 + 16.6 + 41.6

Mean/ E[X] = 59.8

So E[X]²= 59.8² = 3576.04

On the other hand

E[\(x^{2}\)] = \(0^2\) × 1/12 + \(10^2\) × 1/6 + \(50^2\) × 1/3 + \(100^2\) × 5/12

E[\(x^{2}\)] = 0 + 16.6 + 833.3 + 4166.6

E[\(x^{2}\)]  = 5016.5

Then the variance will be:

Var[x]=  E[\(x^{2}\)]  - E[X]²

Var[x] =  5016.5 - 3576.04

Var[x] = 1440.46

Hence, The value of mean is 59.8 and the variance of the sampling distribution is 1440.46

False. Just because two vectors are eigenvectors of the same matrix with different eigenvalues, it does not mean they are orthogonal to each other.

Eigenvectors of a matrix are vectors that, when the matrix is multiplied by them, the vector remains the same except for a scaling factor. Eigenvalues are the scaling factors of the eigenvectors. If two eigenvectors, v1 and v2, of a 4x4 matrix a have eigenvalues 1 and 2 respectively, it does not mean that they are orthogonal (i.e. at a 90 degree angle) to each other. Orthogonality is a property of two vectors that is independent of the matrix and can only be determined by calculating the dot product of the two vectors. Therefore, two eigenvectors of the same matrix with different eigenvalues may or may not be orthogonal to each other.

The solution to this system of linear equations is  (7, 3).

What is equation?

In mathematics, an equation is a formula that expresses the equivalency of two expressions, by connecting them with the equals sign =

Main body:

x - 3y = -2

x = 3y - 2 ….. (1)

x + 3y = 16 …… (2)

Let us solve the system of linear equations using the substitution method.

Substituting x in equation (2)

3y - 2 + 3y = 16

6y = 16 + 2

6y = 18

Divide both sides by 6

y = 3

Substituting the value of y in equation (1)

x = 3 (3) - 2

x = 9 - 2

x = 7

Therefore, the solution is (7, 3).

Answer:

292.75mL

Step-by-step explanation:

From the ideal gas equation

PV= nRT

With each symbols having standard meaning

For pressure remaining constant the equation for two states can be written as

\(\frac{V_1}{T_1}=\frac{V_2}{T_2}\)

Given V_1 = 300mL, T_1 = 17° C = 290K and T_2 = 10°C or 283K

Now plugging values in above equation to find V_2

\(\frac{300}{290} =\frac{V_2}{283}\\V_2 =\frac{300}{290}\times283 = 292.75mL\)

Therefore, the volume at 10 degrees Celsius = 292.75mL

Based on the information provided regarding same as cash loans, Chelsea won't be charged interest for the first 6 months of the loan, nor will she have to make payments for the first 6 months. (Option D)

A Same-As-Cash Loan refers to a short-term lending solution in which no interest or monthly payment are required to be paid during a set “Same-As-Cash” period. At the end of a predetermined period, the loan is paid off. Hence, the customer owes no interest or monthly payments during a set promotional period and pays the same amount on the loan as they would have paid up front with cash. These are interest deferred loans in which the loans interest still accrues during that promotional period, however if the customer pays off the entire principal balance before the period ends, they are not required to pay that interest. The advantage of these loans is that customers may spend the same amount they would have if they had paid with cash up front. Hence, if Chelsea opts for loan that offered 6 months, same as cash, there would be no requirement of payment or interest charged for the 6 months.

Without specific data on the number of students who prefer each option, we cannot calculate the probability.

To determine the probability that a student prefers the zoo or the water park, we need to know the total number of students and the number of students who prefer each option. Without this information, it is not possible to calculate the probability accurately.

To calculate the probability, we would need to divide the number of students who prefer the zoo or the water park by the total number of students. For example, if there are 50 students in total and 30 prefer the zoo and 20 prefer the water park, the probability would be:

P(prefer zoo or water park) = (30 + 20) / 50 = 50 / 50 = 1

Answer:

20258. The missing digit is a 5

Step-by-step explanation:

Ok, let's write the number in a more creative way.  That's \(21 000 - 700 = 20 300\),  minus something else. That something else has to be a multiple of 7, be less than 100, and has to end with a 2. Now start writing down the multiplication table for 7 and find how many of them ends with 2. 42 comes to mind, and that's the only one. (you can go up to 7x14=98 before having one digit too many).

That brings your number to be written as \(21000-700 -42 = 20258.\)

In theory there was a criteria to see if a number was divisible by 7, but I've never learned it.

I agree with the other person. The answer is 5.

Here's how we can check to see if a number is divisible by 7.

If the result of the third step is a multiple of 7, then so is the original value itself. We can repeat the steps to progressively shrink the values down so we have something more manageable.

---------------

Let's use those steps to see if 20,258 is a multiple of 7

It's not clear if 2009 is a multiple of 7 or not; however, we can apply the same three steps to shrink the number down. This process can be repeated as many times as you like.

Like before, the result 182 is fairly big and it's not clear if we have a multiple of 7. Luckily, we only need to do one more round of those steps.

The result 14 is a multiple of 7, which means that 182 is also multiple of 7. By a domino-like chain reaction, the values 2009 and 20258 are also multiples of 7.

Notes:

---------------

We've just verified that 20258 is a multiple of 7. Let's go over an example a non-multiple of 7. I'll add 1 to the number 20258 so we are guaranteed that it cannot possibly be a multiple of 7. Doing the round of steps as shown above should get us to some smaller non-multiple of 7.

Repeat the steps until we get something more manageable

Let's do one more round

The value 6 is not a multiple of 7, and neither are 186 and 2007 and 20259.

If you have your calculator with you, then you should see that dividing any of those values over 7 will not lead to a whole number result.

This is a fairly quick and efficient way to check divisibility by 7 if you are in a hurry.

The other angle of the triangle is 65°.

We know that

Exterior Angle = Sum of two angles opposite to the exterior angle

Here, 145° = 80° + x°

=> x° = (145 – 80)°

=> x° = 65°

Therefore, the value of x in the given figure is 65°
