Given the equation : y=-0.02(x-18)^2+12 to model the horizontal distance of a ball from Amaya's position.
a. How far away is the ball from Amaya when it is at its maximum height?
The model takes the form of a parabolic equation. Maximum height is obtain at the Vertex :
Comparing the general model :
y = a(x - h)^2 + k
Maximum height is obtained at the Vertex :(h, k)
From the model given
Coordinate at the Vertex : (h, k) = (18, 12)
Hence, ball is 18 feets away from AMAYA
B.) Height of ball at x = 30
y=-0.02(x-18)^2+12
y=-0.02(30-18)^2+12
y=-0.02(12)^2+12
y = 9.12 feets.

Answer:
Y = $30 + $8x
Step-by-step explanation:
Given that:
Shipping World International Shipping rate = $30 plus $8 per pound per package
Where ;
$30 is a constant fee
$8 is the fee charged per pound weight of package
Let weight of package in pounds = x
Y = shipping rate * weight of package
Y = $30 + $8x

In a 2-sample z-test for two proportions, you find the following: X1 = 24 n1 = 200 X2 = 17 my = 150 You decide
to run a test for which the alternative hypothesis is Hj: p1 > p2- Find the appropriate test statistic for the
test. Enter the test statistic - round to 4 decimal places. Z =
The appropriate test statistic for this test is approximately 0.2103 (rounded to 4 decimal places).
To find the appropriate test statistic for a 2-sample z-test for two proportions, we need to calculate the standard error and then use it to compute the z-score. The formula for the standard error is:
SE = sqrt[(p1 * (1 - p1) / n1) + (p2 * (1 - p2) / n2)]
Where p1 and p2 are the sample proportions, and n1 and n2 are the sample sizes.
In this case, we have the following values:
X1 = 24 (number of successes in sample 1)
n1 = 200 (sample size 1)
X2 = 17 (number of successes in sample 2)
n2 = 150 (sample size 2)
To calculate the sample proportions, we divide the number of successes by the respective sample sizes:
p1 = X1 / n1 = 24 / 200 = 0.12
p2 = X2 / n2 = 17 / 150 = 0.1133
Now, we can plug these values into the formula to calculate the standard error:
SE = sqrt[(0.12 * (1 - 0.12) / 200) + (0.1133 * (1 - 0.1133) / 150)]
SE ≈ 0.0319
Finally, the test statistic (z-score) is calculated by subtracting the two sample proportions and dividing by the standard error:
Z = (p1 - p2) / SE
Z = (0.12 - 0.1133) / 0.0319
Z ≈ 0.2103
Therefore, the appropriate test statistic for this test is approximately 0.2103 (rounded to 4 decimal places).

(Round to one decimal place as needed) c) Do the two percentages agree? Why or why not? OA. Yes, because a Normal probability plot shows that the Normal model is appropriate OB. No, because a Normal probability plot shows that the Normal model is appropriate O C Yes, because a Normal probability plot shows that the Normal model is not appropriate O D. No, because a Normal probability plot shows that the Normal model is not appropriate
The two percentages do not agree. Hence, option D is correct.
a) The mean time was 103.59 seconds, with a standard deviation of 5.16 seconds. If the Normal model is appropriate, the percentage of times that will be less than 98.43 seconds can be calculated as follows:
z = (x - μ) / σz = (98.43 - 103.59) / 5.16z = -1.00Using z-score table, we can determine that the percentage of times that will be less than 98.43 seconds is approximately 15%.
Therefore, the percentage of times that will be less than 98.43 seconds is 15%.
(Round to the nearest integer as needed)Hence, option A is correct.b) The actual percentage of times less than 98.43 seconds can be calculated by finding the number of competitors that finished with a time less than 98.43 seconds and dividing that number by the total number of competitors.
98.06, 98.09, 98.46, 98.47, 98.96, 98, 99, 99.12, 99.35, 99.57, 99.98, 100.08, 100.11, 100.28, 100.64, 101.32, 101.06, 101.25, 101.34, 101.39, 102.48,

There are no competitors who finished with a time less than 98.43 seconds. Therefore, the actual percentage of times less than 98.43 seconds is 0%. (Round to one decimal place as needed)Thus, option D is correct.c) The two percentages do agree.
This is because the Normal probability plot shows that the Normal model is not appropriate.
Therefore, the actual percentage of times less than 98.43 seconds is 0%, which is different from the percentage that was calculated using the Normal model. Since the Normal model is not appropriate, the actual percentage of times is more accurate.

Briefly discuss the difference between these two models and explain why the real estate should have its own asset allocation model.
The difference between the two models and why real estate should have its own asset allocation model.
The Sharpe ratio is a measure of risk-adjusted return. It is calculated by dividing the excess return of an investment over a benchmark by the standard deviation of the investment's returns. The higher the Sharpe ratio, the better the investment's risk-adjusted return.
The Cheng, Lin, and Liu model is a more complex model that takes into account the time horizon of the investment, the volatility of the investment, and the correlation between the investment and the benchmark. The model is designed to maximize the Sharpe ratio of the investment over a specified time horizon.
The real estate market is different from the financial market in several ways. Real estate is a illiquid asset, meaning that it can be difficult to sell quickly. Real estate is also a cyclical asset, meaning that its prices tend to go up and down over time. Real estate is also a heterogeneous asset, meaning that there is a wide variety of properties available, each with its own unique characteristics.
Because of these differences, the real estate market should have its own asset allocation model. A model that is designed for the financial market may not be appropriate for the real estate market. A real estate asset allocation model should take into account the illiquidity, cyclicality, and heterogeneity of the real estate market.
Here are some additional reasons why real estate should have its own asset allocation model:
Real estate is a long-term investment. The typical holding period for real estate is 10 years or more. This is different from the financial market, where the typical holding period is much shorter.
Real estate is a leveraged investment. This means that investors can use borrowed money to purchase real estate. This can magnify the potential returns of real estate, but it can also magnify the potential losses.
Real estate is a local investment. The value of real estate is often driven by local factors, such as the job market, the economy, and the demographics. This means that real estate investments should be tailored to the specific market in which they are located.
Overall, the real estate market is different from the financial market in several ways. These differences make it important for real estate investors to have their own asset allocation model.

Write the equation of the line with a slope of 34 and a y-intercept of −7 in Slope-Intercept and Point-Slope Form.
The linear equation of the line is y = 34x - 7 and y + 7 = 34(x - 0)
How to determine the line equation?The slope is given as:
m = 34
The y-intercept is given as:
c = -7
A linear equation in slope intercept form is represented as:
y = mx + c
So, we have:
y = 34x - 7
The equation in point slope form is calculated as follows:
y = 34x - 7
Add 7 to both sides
y + 7 = 34x
Express 34x as 34(x)
y + 7 = 34(x)
Subtract 0 from x
y + 7 = 34(x - 0)
Hence, the linear equation of the line is y = 34x - 7 and y + 7 = 34(x - 0)

= 0,6( − T) = 900 − 50 = 700, T = 875 ( / P ) = 0,25 − 62,5 ( / P ) = 400 where C = consumption, Y = GDP, T= taxes, G = government spending, (/P)= real money demand cash and (/P) = real money supply cash 1. What is the equation of the IS curve? 2. What is the equation of the LM curve? 3. What are the equilibrium values of the real interest rate and real GDP? 4. What is Keynesian Multiplier 5. What is the impact of an increase in government spending on GDP and the rate of of interest? 6. What is the impact on national savings and the government budget balance of this increase?
To answer your questions, we need to analyze the given equations and variables:
Equation 1: C = 900 - 50T
Equation 2: Y = 400
Equation 3: (M/P) = 0.25 - 62.5r
Equation 4: (M/P) = 400
The equation of the IS curve represents the equilibrium relationship between real GDP (Y) and the real interest rate (r). From Equation 2, we can see that the equation of the IS curve is Y = 400.
The equation of the LM curve represents the equilibrium relationship between the real interest rate (r) and the level of real money supply (M/P). From Equations 3 and 4, we can equate the expressions for (M/P) and solve for r:
0.25 - 62.5r = 400
-62.5r = 400 - 0.25
-62.5r = 399.75
r ≈ -6.396
Therefore, the equation of the LM curve is r ≈ -6.396.
To find the equilibrium values of the real interest rate (r) and real GDP (Y), we need to find the point where the IS curve intersects the LM curve. From Equation 2, we already know that Y = 400. Substituting this into the equation of the LM curve, we can solve for r:
400 = -6.396
Therefore, the equilibrium values of the real interest rate and real GDP are r ≈ -6.396 and Y = 400.
The Keynesian multiplier represents the impact of changes in autonomous spending on the overall change in equilibrium output (GDP). In this case, we don't have information about autonomous spending (investment), so we can't calculate the Keynesian multiplier.
An increase in government spending (G) would shift the IS curve to the right. This would lead to an increase in GDP (Y) and potentially a decrease in the real interest rate (r) as the IS and LM curves intersect at a higher level of output. However, without more information about the magnitude of the increase in government spending, we cannot determine the exact impact on GDP and the rate of interest.
The impact on national savings and the government budget balance of the increase in government spending depends on the financing of the spending increase. If the government increases taxes (T) or borrows to finance the higher spending, it may impact national savings and the government budget balance. However, based on the given equations, we do not have sufficient information to determine the specific impact on these variables.

Factorizing the given polynomial: We need to find the factors of 2 × -12 = -24 which add up to 5.-3 and 8 are the factors of -24 and add up to 5.
Hence, [tex]2x^2 + 5x - 12 = (2x + 3)(x - 4)[/tex]
Polynomial [tex]3: 3x^2 - 9x - 12[/tex]
Factorizing the given polynomial: We can factor 3 out from the given polynomial. [tex]3(x^2 - 3x - 4) = 3(x - 4)(x + 1)[/tex]
Hence, [tex]3x^2 - 9x - 12 = (x - 4)(3x + 1)[/tex]
Therefore, the polynomial and the factored expression that match with each other are:

What is the slope of a line perpendicular to the line y = 2x + 5?
A. 1/2
B. -2
C. 2
D. -1/2
Answer: A
Step-by-step explanation: You get y = -2x +5, so the slope is –2. Perpendicular lines have opposite-reciprocal slopes, so the slope of the line we want to find is 1/2. Plugging in the point given into the equation y = 1/2x + b and solving for b, we get b = 6. Thus, the equation of the line is y = ½x + 6.
