We are asked to determine the equation of an ellipse that has a base of 40 feet and a height of 18 feet. This can be visualized in the following diagram:

The general form of the equation of an ellipse is:

We have set the origin of the coordinate system to be in the middle of the ellipse. The value of "a" is the x-intercept of the ellipse and the value of "b" is the y-intercept of the ellipse. Therefore, the equation is:

Now, we solve the squares:

And thus we have determined the equation of the ellipse.

A graph of the given system of equations f(x) = 2x² - 8x + 3 and g(x) = -2x + 3 is shown in the image attached below.

The points that make both equations true is (0, 3)

In Mathematics, a graph can be defined as a type of chart that is typically used to graphically represent data points or ordered pairs on both the horizontal and vertical lines of a cartesian coordinate, which are the x-coordinate and y-coordinate respectively.

In Mathematics, the graph of every quadratic equations (functions) is either an upward or downward parabola, which is typically a u-shaped curve. This ultimately implies that, the graph of a quadratic equation (function) would always form a parabolic curve.

Based on the graph (see attachment), we can logically deduce that the solution to the given system of equations is the point of intersection of the lines on the graph representing each, which is the ordered pair (0, 3);

f(x) = 2x² - 8x + 3

3 = 2(0)² - 8(0) + 3

3 = 3 (True).

g(x) = -2x + 3

3 = -2(0) + 3

3 = 3 (True).

Answer:

Exponential growth, as the sign of the basis (the number 1.15) is positive.

Step-by-step explanation:

The equation Y = 250,000(1.15)ˣ represents exponential growth.

In this equation, the base of the exponential term is 1.15, which is greater than 1. When the exponent x increases, the value of the term (1.15)ˣ also increases, leading to exponential growth.

Exponential growth occurs when a quantity increases at an accelerating rate over time. In this case, as x increases, the value of Y grows exponentially, indicating growth rather than decay.

Therefore, the equation Y = 250,000(1.15)ˣ represents exponential growth.

James will fully clear the loan after approximately 12 years when the remaining balance reaches zero.

To determine the number of years it will take for James to fully clear the loan, we need to calculate the remaining balance after each payment and divide the initial loan amount by the annual payment until the remaining balance reaches zero.

The loan amount is 9000 euros, and James pays off 770 euros each year. Since the interest is charged at a rate of 3% of the original amount per annum, the interest for each year will be \(0.03 \times 9000 = 270\) euros.

In the first year, James pays off 770 euros, and the interest on the remaining balance of 9000 - 770 = 8230 euros is \(8230 \times 0.03 = 246.9\)euros. Therefore, the remaining balance after the first year is 8230 + 246.9 = 8476.9 euros.

In the second year, James again pays off 770 euros, and the interest on the remaining balance of 8476.9 - 770 = 7706.9 euros is \(7706.9 \times 0.03 = 231.21\) euros. The remaining balance after the second year is 7706.9 + 231.21 = 7938.11 euros.

This process continues until the remaining balance reaches zero. We can set up the equation \((9000 - x) + 0.03 \times (9000 - x) = x\), where x represents the remaining balance.

Simplifying the equation, we get 9000 - x + 270 - 0.03x = x.

Combining like terms, we have 9000 + 270 = 1.04x.

Solving for x, we find x = 9270 / 1.04 = 8913.46 euros.

Variance of the die which rolled twice is 5.83

According to the statement

we have given that the six-faced and balanced, die will be rolled twice.And we have to find the variance of the X.

For this purpose, we know that the

The variance is a measure of variability. It is calculated by taking the average of squared deviations from the mean.

And the formula of variance is

\(Var(X) = \sum_{i=1}^6(X_i-\bar{X})^2\over{6}\)

By this we calculate the variance.

Firstly variance for the one die:

Mean of the die = 1+2+3+4+5+6 /6

Mean of the die = 21 /6

Mean of the die = 3.5

And then variance become

\(= {(1-3.5)^2+(2-3.5)^2+(3-3.5)^2+(4-3.5)^2+(5-3.5)^2+(6-3.5)^2}\over{6}\)

\(= (\frac{17.5}{6} )^{2} \\\)

= 105/36

= 2.91.

So, variance of one die is 2.91 then variance for 2 die is 2.91 *2 = 5.83.

Hence, Variance of the die which rolled twice is 5.83.

The sinusoidal graph shown has an amplitude of 1, a period of 4π/5, and no phase shift. The equation for the sinusoidal graph can be written as y = sin((2π/4π/5)x).

The amplitude of a sinusoidal graph represents the maximum value the graph reaches from the centerline. In this case, the amplitude is given as 1, indicating that the graph oscillates between -1 and 1.

The period of the sinusoidal graph is the distance it takes for the graph to complete one full cycle. Here, the scale on the x-axis is π/10, and the graph completes one cycle within 2 units on the x-axis. Therefore, the period is 2 * π/10 = π/5. However, the standard form of a sinusoidal equation uses a period of 2π, so we need to adjust it. The adjusted period is 4π/5.

The phase shift determines how the graph is shifted horizontally. In this case, there is no phase shift mentioned, which means the graph is not horizontally shifted.

Combining these values, we can write the equation for the sinusoidal graph as y = sin((2π/(4π/5))x), which simplifies to y = \(sin((\frac{5}{4}x))\).

Therefore, the equation for the given sinusoidal graph is y = \(sin((\frac{5}{4}x))\), with an amplitude of 1, a period of 4π/5, and no phase shift.

we need to first calculate the deviation of a GPA less than 1.85 from the mean GPA of 2.3, Deviation = 1.85 - 2.3 = -0.45 Next, we need to calculate the z-score for this deviation using the formula: z = (x - μ) / σ .

where x is the value we want to convert to a z-score, μ is the population mean, and σ is the population standard deviation. z = (-0.45 - 2.3) / 0.7 = -3.07, We can use a z-score table or calculator to find the percentage of the population that falls below this z-score.

According to the table, the percentage of the population with a z-score less than -3.07 is approximately 0.001. Therefore, the percentage of students who will be dropped from college is approximately 0.1% (or 0.001 x 100).
The Z-score formula is: Z = (X - μ) / σ.

Where X is the GPA value (1.85), μ is the mean (2.3), and σ is the standard deviation (0.7). Z = (1.85 - 2.3) / 0.7 = -0.64
Now, we'll use the standard normal distribution table to find the percentage of students corresponding to a Z-score of -0.64. The table gives us a value of 0.2611.Thus, approximately 26.11% of the students with a GPA less than 1.85 will be dropped from college.

The equation is false (we can remove the dependence with the variable x) that is why the equation has no solutions.

Here we have the following linear equation:

5 - 4x - 7 - 10x = -8x - 4 - 6x - 10

We want to see why we don't have any solutions, to check that, we need to simplify both sides of the equation. Let's start by grouping like terms:

5 - 4x - 7 - 10x = -8x - 4 - 6x - 10

(5 - 7) + (-4x - 10x) = (-4 - 10) + (-8x - 6x)

-2 - 14x = -14 - 14x

Notice that now we can add 14x in both sides of the equation, then we will get:

-2 -14x + 14x = -14 - 14x + 14x

-2 = -14

It is true that, Statistically, using z-scores, a group mean can be compared to a population mean to ascertain whether or not the group mean is different from the population mean.

Hypothesis testing is a statistical method for making inferences about a population based on sample data.

It involves formulating a null hypothesis, which is a statement about the population that we want to test, and an alternative hypothesis, which is a statement that contradicts the null hypothesis.

Here we have a statement

Statistically, using z-scores, a group mean can be compared to a population mean to ascertain whether or not the group mean is different from the population mean.

The above statement is true

Z-scores are a measure of the distance between a sample mean and the population mean in standard deviation units.

By using z-scores, we can compare a group mean to a population mean and determine whether the difference is statistically significant.

To do this, we calculate the z-score using the formula:

z = (x - μ) / (σ / sqrt(n))

If the resulting z-score falls in the rejection region of the standard normal distribution, we can reject the null hypothesis that the sample mean is not significantly different from the population mean.

In summary, comparing a group mean to a population mean using z-scores is a common statistical technique to determine whether there is a significant difference between the two means.

Therefore,
