Solving provided question, we can say that value of standard deviation will be 3.28634 and Mean (Average) = 5 and Variance (SD) = 10.8

Standard deviation is a statistic that expresses the variability or variance of a group of numbers. While a high standard deviation suggests that the values are more dispersed, a low standard deviation suggests that the values tend to be closer to the established mean. A measure of how dispersed the data are from the mean is the standard deviation (or ). When the standard deviation is low, the data tend to be grouped around the mean, and when it is large, the data are more dispersed. The average variability of the data set is measured as standard deviation. It reveals the average deviation of each score from the mean.

The statement holds for all positive integers n, and a tree with n nodes contains n-1 edges.

The statement can be proven by induction.

Base case: If a tree has one node, then it has no edges (n = 1, n-1 = 0).

Inductive step: Assume the statement is true for n = k (i.e. a tree with k nodes contains k-1 edges). We prove it is true for n = k+1.

Let T be a tree with k + 1 nodes, and let v be any node in T. Then, since T is a tree, v must have exactly one parent node and k-1 child nodes (or no child nodes at all). Let T' be the subtree of T rooted at v, which has k nodes. By the inductive hypothesis, T' has k-1 edges.

Since v has exactly one parent node, there is exactly one edge connecting it to its parent in T. Thus, T has k-1 + 1 = k edges, which means the statement holds for n = k + 1.

Therefore, by induction, the statement holds for all positive integers n, and a tree with n nodes contains n-1 edges.

(0.25 s) = -1.8 m/s ,the numerical value of the vertical velocity of the car at time t = 0.25s, which was found to be -1.8m/s.

Part D:

In order to find the expression for the vertical velocity of the car, we need to use both the chain and product rules of differentiation. The chain rule states that if f(x) is a function of g(x), then the derivative of the function is equal to the derivative of g(x) multiplied by the derivative of f(x). The product rule states that if two functions, f(x) and g(x), are multiplied together, then the derivative of the product is equal to the derivative of f(x) multiplied by g(x) plus the derivative of g(x) multiplied by f(x).

Using the chain rule, we can find the derivative of the position-time equation:

y'(t) = yo'e-21 -yde (a cos(wt) + w sin(wt))

Using the product rule, we can find the derivative of the position-time equation:

v(t) = owyo'e-21 -yde (a cos(wt) + w sin(wt)) cos(wt) sin(wt) + yoe- (cos(wt) + aw cos(wt))

Simplifying the expression, we find:

v(t) = ayo'e-20t -w cos(wt) sin(wt)

Part E:

In order to evaluate the numerical value of the vertical velocity of the car at time t = 0.25s, we need to plug the given values for yo, a, and w into the expression for the vertical velocity.

Substituting the given values into the expression, we find:

v(0.25s) = 0.75e-20(-6.3)cos(6.3*0.25)sin(6.3*0.25)

Simplifying the expression, we find:

v(0.25s) = -1.8 m/s

In this example, we used the chain and product rules of differentiation to find the expression for the vertical velocity-time relationship for the car from its position-time relationship. We then used this expression to evaluate the numerical value of the vertical velocity of the car at time t = 0.25s, which was found to be -1.8m/s.

Area = (10 + 0)/2 * (2*10 + 15 - 2*0 + 15)

Area = (10 + 0)/2 * (35)

Area = 175

The integral, in this case, is the area under the line y = 2x + 15 between x = 0 and x = 10. The diagram for this looks like a trapezoid with the base of 10, the left side y = 15, the right side y = 25, and the height of 10. To calculate the area, we use the formula for the area of a trapezoid, which is (b1 + b2)/2 * h, where b1 and b2 are the lengths of the two bases and h is the height. For this problem, b1 is 0 and b2 is 10, and h is 10, so the area of the trapezoid is (10 + 0)/2 * (2*10 + 15 - 2*0 + 15). This simplifies to (10 + 0)/2 * (35), which is 175.

To solve the equation 2x^2 + 5x - 3 = 0, we can use the quadratic formula:

x = (-b ± √(b^2 - 4ac)) / 2a

Where a = 2, b = 5, and c = -3.

Plugging in the values, we get:

x = (-5 ± √(5^2 - 4 * 2 * -3)) / 2 * 2

x = (-5 ± √(25 + 24)) / 4

x = (-5 ± √49) / 4

x = (-5 ± 7) / 4

So, the two solutions are:

x = ( -5 + 7 ) / 4 = (2) / 4 = 1/2

x = ( -5 - 7 ) / 4 = (-12) / 4 = -3

So, the two solutions to the equation 2x^2 + 5x - 3 = 0 are x = 1/2 and x = -3.

Answer:

The answer is B) x = 1/2, -3.

Step-by-step explanation:

The equation 2x^2 + 5x - 3 = 0 can be solved using the quadratic formula, which states that the solutions to a quadratic equation of the form ax^2 + bx + c = 0 are given by:

x = (-b ± √(b^2 - 4ac)) / (2a)

where a, b, and c are the coefficients of the equation and ± represents both the positive and negative square root.

In this case, a = 2, b = 5, and c = -3. Plugging these values into the formula gives us:

x = (-5 ± √(5^2 - 4 * 2 * -3)) / (2 * 2)

x = (-5 ± √(25 + 24)) / 4

x = (-5 ± √(49)) / 4

x = (-5 ± 7) / 4

So the two solutions are:

x = (-5 + 7) / 4 = 2 / 4 = 1/2

x = (-5 - 7) / 4 = -12 / 4 = -3

Therefore, the solutions to the equation 2x^2 + 5x - 3 = 0 are x = 1/2 and x = -3, which corresponds to option B) x = 1/2, -3.

Using Laplace Transformation, the initial value problem y" - 2y' + y = 0 , y(0) = 1 , y'(0) = 2 is y(t) = e^t + te^t.

The differential equation is y" - 2y' + y = 0 and y(0) = 1 , y'(0) = 2

As we know that the Laplace Equation is:

[tex]L(y^n(t)) = s^nf(s) - s^{n-1}y(0) - s^{n-2}y'(0)-\dots-sy^{n-2}(0)-y^{n-1}(0)[/tex]

Now applying the Laplace Transformation in the differential equation

L(y") - 2L(y') + L(y) = 0........(1)

Now finding the value of L(y") using the equation

L(y") = s^2f(s) - s(1) - 2

L(y") = s^2f(s) - s - 2

Now finding the value of L(y') using the equation

L(y') = sf(s) - 1

Now finding the value of L(y) using the equation

L(y) = f(s)

Now putting the values in the equation 1

s^2f(s) - s - 2 - 2(sf(s) - 1) + f(s) = 0

Now solving

s^2f(s) - s - 2 - 2sf(s) + 2 + f(s) = 0

s^2f(s) - s - 2sf(s) + f(s) = 0

Taking common f(s) in term terms of f(s)

(s^2 - 2s + 1)f(s) - s = 0

Add s on both side, we get

(s^2 - 2s + 1)f(s) = s

We can write (s^2 - 2s + 1) as (s - 1)^2

(s - 1)^2f(s) = s

Divide by (s - 1)^2 on both side, we get

f(s) = s/(s - 1)^2

The inverse Laplace of f(s) = s/(s - 1)^2 is

This statement implies that Mike and Chance were picking apples together and that Chance picked three times as many apples as Mike.

Let's say Mike picked "x" apples. Then, according to the statement, Chance picked 3 times as many apples as Mike, which would be 3x apples.

Let x be the number of apples picked by Mike.

Then, the number of apples picked by Chance would be 3 times that, or 3x apples.

So, the equation can be written as:

x + 3x = total number of apples picked by both Mike and Chance.

Combining like terms, we get:

So the total number of apples picked by Mike and Chance together would be x + 3x = 4x apples.

Let length of vector is 5 then the vector in the direction of  ⟨−3,−1,5⟩ will be ⟨−15/√35,−5/√35,25/√35⟩.

What is a Vector?

Vectors, in Maths, are objects which have both, magnitude and direction. Magnitude defines the size of the vector. It is represented by a line with an arrow, where the length of the line is the magnitude of the vector and the arrow shows the direction. It is also known as Euclidean vector or Geometric vector or Spatial vector or simply “vector“.

Two vectors are said to equal if their magnitude and direction are the same. It plays an important role in Mathematics, Physics as well as in Engineering. According to vector algebra, a vector can be added to another vector, head to tail. The order of addition of two vectors does not matter, because the result will be the same.

Now,

The idea is based on a concept of scaling and similarity.

Any vector that "has the same direction" as

⟨−3,−1,5⟩

has all the coordinates proportional to this given vector and, therefore, can be described by coordinates

⟨−3f,−1f,5f⟩

where f is a scaling factor.

All we need now is to find a scaling factor that leads to a vector with the length 5

The length of a vector with coordinates

⟨−3f,−1f,5f⟩

So, if we want the length to be equal to 5, we should choose

f=5/√35

Hence,

          The coordinates of a vector with the same direction as  ⟨−3,−1,5⟩ but with the length 5 will be ⟨−15/√35,−5/√35,25/√35⟩.

The Normal model is a good approximation for the sampling distribution.

a) According to the Central Limit Theorem, the theoretical mean and standard deviation for a sample size of 20 should be 0.05 and 0.02, respectively. For a sample size of 100, the theoretical mean and standard deviation should be 0.05 and 0.01, respectively.

b) The observed mean and standard deviation for a sample size of 20 was 0.052 and 0.021, respectively. For a sample size of 100, the observed mean and standard deviation was 0.051 and 0.012, respectively. These values are fairly close to the theoretical values.

c) Looking at the histograms in Exercise 1, I would be comfortable using the Normal model as an approximation for the sampling distribution at a sample size of 100.

d) The Success/Failure Condition states that the sample size should be large enough for the sampling distribution of the sample proportions to be approximately normal. Since I chose a sample size of 100, which satisfied the condition, I can be confident that the Normal model is a good approximation for the sampling distribution.

The sample size of 100 is large enough for the sampling distribution of the sample proportions to be approximately normal, and the observed mean and standard deviation is close to the theoretical values. Therefore, the Normal model is a good approximation for the sampling distribution.
