0.4 ,40%  the decimal value and the percent of the number of pin knocked down in relation to a perfect core.

Every decimal is indeed a number that is divided into two parts: a whole and then a fraction. Between integer, numeric values are used to express the numerical value of complete and partially whole amounts.

Bowling's ideal score is 300 points.

You learn down pins in 10 frames, which is 120.

Finding the decimal value and the percentage of knocked-down pins in relation to a perfect score is necessary.

120/300 pins must be known down for a perfect score.

0.4 know-down pins are required for a perfect score.

Consequently, the decimal representation of the number of pins removed in relation to a perfect score is equal to 0.

We will increase the decimal value of the number of known down pins necessary for a perfect score by 100 to determine the percentage.

Pins needed to be known down for a perfect score: 0.4% of 100

40% of pins must be known down for a perfect score.

As a result, 40% of the known down pins are necessary for a perfect score.

Based on the graph which shows the relationship between pounds and euros, the value of a is €0 and the value of b is €1.45.

In Mathematics, a proportional relationship is a type of relationship that generates equivalent ratios and it can be modeled or represented by the following mathematical expression:

y = kx

Where:

In order to have a proportional relationship and equivalent ratios, the relationship between pounds (£) and euros (€) must have the same constant of proportionality.

Next, we would determine the constant of proportionality (k) as follows:

Constant of proportionality (k) = y/x

Constant of proportionality (k) = 1.45/1

Constant of proportionality (k) = 1.45.

When x = 0, the value of a is given by:

y = a = 1.45x

a = 1.45(0)

a = €0.

When x = 1, the value of b is given by:

y = a = 1.45x

b = 1.45(1)

b = €1.45.

The estimated current price of the stock is $57.83.

To calculate the stock's current price, we can use the dividend discount model (DDM). The DDM states that the price of a stock is equal to the present value of its future dividends.

In this case, the dividend is expected to grow at a rate of 24% per year for the next 2 years and then at a constant rate of 5% thereafter. We can calculate the dividends for the next two years as follows:

D1 = D0 * (1 + growth rate) = $2.2 * (1 + 0.24) = $2.728

D2 = D1 * (1 + growth rate) = $2.728 * (1 + 0.24) = $3.386

To find the price of the stock at the end of year 2 (P2), we can use the Gordon growth model:

P2 = D2 / (r - g) = $3.386 / (0.09 - 0.05) = $84.65

Next, we need to discount the future price of the stock at the end of year 2 to its present value using the required rate of return. The required rate of return is the risk-free rate plus the product of the stock's beta and the market risk premium:

r = risk-free rate + (beta * market risk premium) = 0.09 + (1.3 * 0.045) = 0.1565

Now, we can calculate the present value of the future price:

P0 = P2 / (1 + r)^2 = $84.65 / (1 + 0.1565)^2 = $57.83

Therefore, based on the given information and calculations, the estimated current price of the stock is $57.83.

Answer:

Since 26 out of a total of 520 batteries were defected and she wants to randomly select 20 batteries for it.

The formula she will be using will be randInt(1,520) to generate 20 random numbers.

The given nonlinear equation x"'+x"+x'x + x = p(t) with initial conditions x(0)=10, x'(0) = 0, x"'(0)=100 can be converted to state-space form, which consists of a set of first-order differential equations.

To convert the given nonlinear equation to state-space form, we introduce state variables. Let's define:

x₁ = x (position),

x₂ = x' (velocity),

x₃ = x" (acceleration).

Taking derivatives with respect to time, we have:

x₁' = x₂,

x₂' = x₃,

x₃' = p(t) - x₃x₂ - x₁.

Now, we have a set of three first-order differential equations. Rewriting them in matrix form, we get:

[x₁'] = [0 1 0] [x₁] + [0] [x₂] + [0] [x₃] + [0] [p(t)],

[x₂'] = [0 0 1] [x₁] + [0] [x₂] + [0] [x₃] + [0] [p(t)],

[x₃'] = [-1 0 0] [x₁] + [0] [x₂] + [-x₂] [x₃] + [1] [p(t)].

The state-space representation is given by:

x' = Ax + Bu,

y = Cx + Du,

where x = [x₁ x₂ x₃]ᵀ is the state vector, u is the input vector, y is the output vector, A, B, C, and D are matrices derived from the above equations.

In this case, A = [[0 1 0], [0 0 1], [-1 0 0]], B = [[0], [0], [1]], C = [[1 0 0]], and D = [[0]]. The initial conditions are x₀ = [10 0 100]ᵀ.x"'+x"+x'x + x = p(t) with initial conditions x(0)=10, x'(0) = 0, x"'(0)=100 can be converted to state-space form, which consists of a set of first-order differential equations.

The answer is yes, (x + 6) is a possible length of a rectangle with area x² + x − 30.

To determine whether (x + 6) is a possible length of a rectangle with area x^² + x − 30, we can use an area model to visualize the situation.

First, we need to find the width of the rectangle.

The area of a rectangle is given by the formula A = lw,

where A is the area, l is the length, and w is the width.

We are given that the area is x² + x − 30, so we can set this equal to lw and solve for w:

x² + x − 30 = (x + 6)w

w = (x² + x − 30)/(x + 6)

The length of a rectangle must be greater than or equal to its width, so we need to check whether (x + 6) is greater than or equal to (x² + x − 30)/(x + 6). This simplifies to:

(x + 6) ≥ x² + x − 30

Expanding the left side and simplifying, we get:

x² + 12x + 36 ≥ x² + x − 30

11x ≥ -66

x ≥ -6

Since x must be a positive number (since we are dealing with lengths), we can conclude that (x + 6) is the possible length of the rectangle. Therefore, the answer is yes, (x + 6) is a possible length of a rectangle with an area x² + x − 30.

From hypothesis testing, the test statistic value for two samples is 0.30. The p-value = 0.766> 0.05, null can't reject the null hypothesis. So, there is no evidence to support claim that a difference in population mean percentage increases for corporate revenue and CEO salary. So, option(A) is right one.

For comparing means of two population where population variance are unknown, then our hypothesis is \(H_0 :μ_1−μ_2 =ξ_0 \)

\(H_1 :μ_1−μ_2 ≠ξ_0\)

The test statistic for the given hypothesis is \(T= \frac{ (\bar x_{1} − \bar x_2) - ξ_0}{ \sqrt{\frac{ s²_1}{n_1} + \frac{ s²_2}{n_2}}}\)

\( s_ i = ∑_{j=1}^{n_i}\frac{ x_{ij} - \bar x_i}{ n_i - 1} \\ \)

Now, there are america's top chief executive officers. Let's consider A denotes be the CEO's annual percentage salary increase and B denote be the annual company percentage increase in revenue, in that same company. To test the different of population mean percentage increase in corporate revenue \((μ_B)\) and the population mean percentage increase in CEO salary \((μ_A)\). We need the hypothesis as : For A sample, \(n_1 = 8\)

sample mean \(\bar x_1 = \sum_{j = 1}^{n_1} x_{ij} = 16.13 \\ \)

Standard deviations, \(sd_1 = \sqrt{ \sum_{j = 1}^{8} \frac{ x_{1j} - \bar x_1}{n_1 - 1} } \\ \)

= 9.46

Similarly for B, \(n_2 = 8\)

sample mean \(\bar x_2 = \sum_{j = 1}^{n_2} x_{ij} = 17.28 \\ \)

standard deviations, \(sd_2 = \sqrt{ \sum_{j = 1}^{8} \frac{ x_{1j} - \bar x_2}{n_2- 1} } \\ \)

=11.8

d = \(\bar x_1 - \bar x_2 = 1.67\)

Therefore the test statistic :

\(T= \frac{ 1.67 - 0}{ \sqrt{\frac{ 9.41²}{8} + \frac{11.8² }{8}}}\)

= 0.30

degree of freedom, df = 8 + 8 - 2 = 14

Level of significance= 0.05

The above test statistic follows t-distribution with, so the critical value for t = 0.30 and degree of freedom 14 is equals to 0.766 > 0.05.

Based on obtained answers, we will fail to reject the null hypothesis because p-value is greater than the level of significance then we can says that the data is not statistically significant at level 0.05. Hence, we conclude that there is no enough evidence at the 5% level of significance to the claim that a difference in population mean percentage increases for corporate revenue and CEO salary.

Answer:

a) To calculate the remaining balance on the loan at the end of the first year, you need to first calculate the interest that has accumulated on the loan. This can be done using the formula:

Interest = Principal x Rate x Time

In this case, the interest for the first year would be:

Interest = 150000 x (10/100) x 1 = 15000

So the total amount owed at the end of the first year, including interest, would be:

Total = Principal + Interest = 150000 + 15000 = 165000

Now, after paying Rs 85000 at the end of the first year, the remaining balance on the loan would be:

Remaining Balance = Total - Payment = 165000 - 85000 = 80000

To calculate the amount that needs to be paid at the end of the second year, you need to calculate the interest that has accumulated on the remaining balance of the loan. This can be done using the same formula as before:

Interest = Remaining Balance x Rate x Time = 80000 x (10/100) x 1 = 8000

So the total amount that needs to be paid at the end of the second year would be:

Total = Remaining Balance + Interest = 80000 + 8000 = 88000

b) If he had paid the loan only at the end of second year, the interest would have been:

Interest = Principal x Rate x Time = 150000 x (10/100) x 2 = 30000

Thus, he would have paid 30,000 more than he paid by paying partly at the end of first year.

The sequence is neither arithmetic nor geometric.

Informally, a sequence in mathematics is a list of items that are in some order (or events). It possesses members, much like a set (also called elements, or terms). The length of the series is the number of ordered elements in the sequence, which could be unlimited.

Also, Arithmetic sequences, geometric sequences, quadratic sequences, and special sequences are the four primary categories of distinct sequences you need to be familiar with.

Squares, rectangles, circles, cones, cubes, and other shapes that can be created using geometry are known as geometric forms. In structural, civil, and architectural engineering, geometric forms are frequently used.

Statistics is a set of mathematical procedures used to collect, analyze, and interpret data.

Generally, it involves collecting data from a sample population, organizing the data into a meaningful manner, and then applying statistical methods to draw conclusions from the data. Statistical methods include descriptive statistics, which summarize the data, and inferential statistics, which use the data to make predictions about a larger population.

Descriptive statistics uses various measures to summarize a population, such as the mean, median, and mode. The mean is the average of all the values in a population and is calculated by adding up all the values and dividing by the number of values. The median is the middle value when all the values in a population are arranged from smallest to largest. The mode is the most frequently occurring value in a population.

Inferential statistics uses the data from a sample population to make predictions about a larger population. For example, a researcher might use a statistical test to determine if a certain treatment is effective. The researcher would collect data from a sample of the population, then use a statistical test to determine if the treatment had an effect on the sample population. If the test is statistically significant, then the researcher can conclude that the treatment is likely to have an effect on the larger population.
