please HElp WAS DUE YESTERDAY this is my last question
here is a system of two linear equations. how do i verify that the solution is (3,4)

Equation A1; y=x+1

Equation A2; y=-2x+10

Answer:

The answer is c which is=5605

Answer:

C.

Step-by-step explanation:

Since there's no sequence of numbers, we assume that the number that lies between 5,595 and 5,610 is the mean of the 2 numbers.

However, if we calculate its mean, we can have 5,602.5 and it doesn't appear on any options. Thus, we will choose the nearest value from those options.

The null hypothesis would state that the population mean number of cups of coffee that women would drink 32% the population mean number cups of coffee than men drink.

The term "percentage" comes from the Latin phrase "per centum," which means "by the hundred." With 100 as the denominator, percentages are fractions. In other words, it is a relationship where the value of the entire is always assumed to be 100.

Percentage is a fraction or a ratio in which the value of whole is always 100. For example, if Sam received 30% on his math test, he received 30 points out of 100. It is expressed as 30/100 in fractional form and 30:100 in ratio form.

A certain number or quantity in every hundred is referred to as a percentage. It is a fraction, and the denominator is 100.

The domain is all real numbers and the Range is y ≥ 3.The correct answer is option A.

To determine the domain and range of the quadratic function based on the given table, let's analyze the values.

Domain represents the set of possible input values (x-values) for the function.

Range represents the set of possible output values (y-values) for the function.

From the given data:

x = -1, 0, 1, 4

y = 5, 3, 3, 5, 35

Looking at the x-values, we can see that the function has values for all real numbers. Therefore, the domain of the function is "all real numbers."

Now, let's consider the y-values. The minimum value of y is 3, and there are no y-values less than 3.

Additionally, the maximum value of y is 35. Based on this information, we can conclude that the range of the function is "y ≥ 3" since all y-values are greater than or equal to 3.

Therefore, the correct answer is:A. Domain: all real numbers

Range: y ≥ 3

a) The principal of the account is given as follows: 1238.27 euros.

b) The interest rate of the account is given as follows: 4.3%.

The equation that gives the balance of an account after t years, considering simple interest, is modeled as follows:

A(t) = P(1 + rt).

In which the parameters of the equation are listed and explained as follows:

We can take the ratio between the balances two consecutive years to obtain the interest rate as follows:

r = 1569.4/1504.5 - 1

r = 1.0431 - 1

r = 0.043

r = 4.3%.

After 5 years, the balance was of 1504.50, hence the principal is obtained as follows:

1504.5 = P(1 + 0.043 x 5)

P = 1504.5/(1 + 0.043 x 5)

P = 1238.27 euros.

With bivariate regression, one variable is used to predict another variable using the formula for a straight line. A straight-line relationship underlies regression, but is not a powerful predictive model. So, this statement is False.

In every regression analysis, we employ one or more explanatory variables to assist explain or predict the response variable. These variables may also be referred to as dependent or response variables.

Predictor or independent variables are the many risk factors and confounding factors.

Regression analysis, a method for determining the association between one or more risk variables and a certain outcome variable, includes these definitions.

In order to forecast the value of the single dependent value, multiple regression analysis uses independent variables whose values are known. Each predictor value is given a weight, with the weights indicating how much each predictor contributed to the final forecast.

You can determine the degree to which each independent variable has a linear connection with the dependent variable using a multiple regression model. This is helpful because it enables you to estimate future outcomes by enabling you to understand which elements are likely to impact a specific outcome.

If the first 50 metal-carrying persons are scanned, there is a very high probability of 0.9998 (approximately) that the first person who is carrying metal will not be missed (not detected).

The probability that the first metal-carrying person missed (not detected) is among the first 50 metal-carrying persons scanned can be calculated by using the concept of Binomial probability distribution.

Suppose p = 0.2 (Probability of not detecting a metal-carrying person) and q = 0.8 (Probability of detecting a metal-carrying person).

The probability that the first metal-carrying person missed (not detected) is among the first 50 metal-carrying persons scanned can be calculated as follows:P (the first metal-carrying person missed (not detected) is among the first 50 metal-carrying persons scanned)P (X ≤ 50) = P (X = 1) + P (X = 2) + .......+ P (X = 50)

Here, X represents the number of metal-carrying persons that are missed (not detected).

Therefore, we need to calculate the cumulative probability for X = 1 to 50, where X follows a binomial distribution with n = 50 and p = 0.2.P (X ≤ 50) = ∑P (X = r), r = 1 to 50P (X = r) = C(50, r) pr q50 - rP (X ≤ 50) = P (X = 1) + P (X = 2) + .......+ P (X = 50)P (X ≤ 50) = ∑P (X = r), r = 1 to 50P (X ≤ 50) = ∑C(50, r) pr q50 - rW

Here C(50, r) = n! / r! (n-r)!

On substituting the values of p and q, we get, P (X ≤ 50) = ∑C(50, r) (0.2) r (0.8)50 - r, r = 1 to 50On solving the above expression, we get the probability that the first metal-carrying person missed (not detected) is among the first 50 metal-carrying persons scanned as 0.9998.

Therefore, the probability that the first metal-carrying person missed (not detected) is among the first 50 metal-carrying persons scanned is 0.9998 (approximately).

The parabolic antenna gain equation, g = η(πd/λ)², relates the gain (g) of a parabolic antenna to the antenna diameter (d), wavelength (λ), and efficiency (η), enabling the quantification and optimization of antenna performance for various applications.

The parabolic antenna gain equation, g = η(πd/λ)², relates the gain (g) of a parabolic antenna to the antenna diameter (d), wavelength (λ), and efficiency (η). Here's a breakdown of the equation:

πd/λ:

This term represents the ratio of the antenna diameter (d) to the wavelength (λ). It determines the angular resolution and directivity of the antenna. A larger diameter or smaller wavelength results in a higher ratio, leading to increased gain.

(πd/λ)²

: Squaring the ratio enhances the directivity and amplification of the antenna. It signifies the concentration of the electromagnetic signal into a narrower beam.

η:

The efficiency factor accounts for losses in the antenna system, including reflection, absorption, and scattering. It represents the fraction of power effectively radiated or received by the antenna.

By multiplying the efficiency by the squared ratio, we obtain the overall gain of the parabolic antenna.

Therefore, the parabolic antenna gain equation provides a quantitative relationship between the gain of the antenna, its diameter, wavelength, and efficiency. Understanding this equation allows engineers and researchers to optimize antenna performance for various applications, such as telecommunications, radio astronomy, and satellite communications.

R = -2

=====================================================

Explanation:

\(S_0 = 20\) is the initial term because your teacher mentioned \(A_0 = I\) as the initial term.

Then R = -2 is the common difference because we subtract 2 from each term to get the next term. In other words, we add -2 to each term to get the next term.

Here is the scratch work for computing terms S1 through S4.

\(\begin{array}{|l|l|}\cline{1-2}S_{n} = S_{n-1} - 2 & S_{n} = S_{n-1} - 2\\S_{1} = S_{1-1} - 2 & S_{2} = S_{2-1} - 2\\S_{1} = S_{0} - 2 & S_{2} = S_{1} - 2\\S_{1} = 20 - 2 & S_{2} = 18 - 2\\S_{1} = 18 & S_{2} = 16\\\cline{1-2}S_{n} = S_{n-1} - 2 & S_{n} = S_{n-1} - 2\\S_{3} = S_{3-1} - 2 & S_{4} = S_{4-1} - 2\\S_{3} = S_{2} - 2 & S_{4} = S_{3} - 2\\S_{3} = 16 - 2 & S_{4} = 14 - 2\\S_{3} = 14 & S_{4} = 12\\\cline{1-2}\end{array}\)

Then here is S5 though S8

\(\begin{array}{|l|l|}\cline{1-2}S_{n} = S_{n-1} - 2 & S_{n} = S_{n-1} - 2\\S_{5} = S_{5-1} - 2 & S_{6} = S_{6-1} - 2\\S_{5} = S_{4} - 2 & S_{6} = S_{5} - 2\\S_{5} = 12 - 2 & S_{6} = 10 - 2\\S_{5} = 10 & S_{6} = 8\\\cline{1-2}S_{n} = S_{n-1} - 2 & S_{n} = S_{n-1} - 2\\S_{7} = S_{7-1} - 2 & S_{8} = S_{8-1} - 2\\S_{7} = S_{6} - 2 & S_{8} = S_{7} - 2\\S_{7} = 8 - 2 & S_{8} = 6 - 2\\S_{7} = 6 & S_{8} = 4\\\cline{1-2}\end{array}\)

And finally we arrive at S9.

\(S_{n} = S_{n-1} - 2\\\\S_{9} = S_{9-1} - 2\\\\S_{9} = S_{8} - 2\\\\S_{9} = 4 - 2\\\\S_{9} = 2\\\\\)

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

Because we have an arithmetic sequence, there is a shortcut.

\(a_n\) represents the nth term

S9 refers to the 10th term because we started at index 0. So we plug n = 10 into the arithmetic sequence formula below.

\(a_n = a_1 + d(n-1)\\\\a_n = 20 + (-2)(n-1)\\\\a_n = 20 - 2(n-1)\\\\a_{10} = 20 - 2(10-1)\\\\a_{10} = 20 - 2(9)\\\\a_{10} = 20 - 18\\\\a_{10} = 2\\\\\)

In other words, we start with 20 and subtract off 9 copies of 2 to arrive at 20-2*9 = 20-18 = 2, which helps see a faster way why \(S_9 = 2\)

The equation of the hyperbola for the cross section of the cooling tower is x²/8100 - y²/9506.25 = 1.

We must take into account its characteristics in order to formulate the hyperbola's equation for the cooling tower's cross section.

Since the origin serves as the hyperbola's centre, its coordinates are (0, 0).

The left/right opening of the hyperbola indicates that the primary axis is horizontal.

The cooling tower's smallest diameter is 180 metres, which is the same length as the minor axis.

The primary axis' 195 m length and the diameter at its highest point are matched.

The hyperbola's highest point is 80 metres above the centre.

These characteristics allow us to write the hyperbola's equation in standard form:

(x - h)²/a² - (y - k)²/b² = 1

Where (h, k) represents the center of the hyperbola.

Substituting the given values:

Center: (h, k) = (0, 0)

Minor axis: 2a = 180 m, so a = 90 m

Major axis: 2b = 195 m, so b = 97.5 m

Vertical shift: c = 80 m

Now we can write the equation of the hyperbola:

x²/90² - y²/97.5² = 1

Simplifying, we have:

x²/8100 - y²/9506.25 = 1

Step-by-step explanation:

To find the value of z such that the area to the right of z is 0.5, we can use the standard normal distribution table (also known as the z-table). The z-table provides the cumulative probability to the left of a given z-value.

Since the area to the right of z is 0.5, the area to the left of z is also 0.5. We need to find the z-value that corresponds to a cumulative probability of 0.5 (or 50%).

Referring to the z-table, we find that a cumulative probability of 0.5 corresponds to a z-value of 0. This means that the area to the left of 0 is 0.5, and therefore, the area to the right of 0 is also 0.5.

Thus, the value of z when the area to the right of z is 0.5 is 0.

Therefore, the correct option is b. 0.0000.
