Snow Dome Ski Resort has 75 inches of snow. It is currently snowing there at a rate of 1 inch per hour. Mt. Winterpark Ski Resort has 68 inches of snow. Currently it is snowing there at a rate of 2 inches per hour.
a) Make a table or a graph showing the amount of snow from 0 to 10 hours at each resort if the snow continues falling at this rate.
b) Indicate on your table or graph where the amount of snow will be the same at both resorts.
Answer:
a. See explanation for table
b. The 7th hour
Step-by-step explanation:
Given
Ski Resort
\(Base\ Snow = 75in\)
\(Rate = 1in\) hourly
Mt. Winterpark
\(Base\ Snow = 68in\)
\(Rate = 2in\) hourly
First, we need to illustrate the amount of snow as an equation in both cases.
\(Amount = Base\ Snow + Rate * Time\)
Let x be number of hours. and y be the amount of snow
So:
Ski Resort
\(y= 75 + 1* x\)
\(y= 75 + x\)
Mt. Winterpark
\(y= 68 + 2 * x\)
\(y= 68 + 2x\)
Next, we make a table to show the data.
When \(x = 0\)
Ski Resort: \(y = 75 + 0 = 75\)
Mt. Winterpark: \(y = 68 + 2(0) = 68\)
When \(x = 1\)
Ski Resort: \(y = 75 + 1 = 76\)
Mt. Winterpark: \(y = 68 + 2(1) = 70\)
When \(x = 2\)
Ski Resort: \(y = 75 + 2 = 77\)
Mt. Winterpark: \(y = 68 + 2(2) = 72\)
When \(x = 3\)
Ski Resort: \(y = 75 + 3 = 78\)
Mt. Winterpark: \(y = 68 + 2(3) = 74\)
When \(x = 4\)
Ski Resort: \(y = 75 + 4 = 79\)
Mt. Winterpark: \(y = 68 + 2(4) = 76\)
When \(x = 5\)
Ski Resort: \(y = 75 + 5 = 80\)
Mt. Winterpark: \(y = 68 + 2(5) = 78\)
When \(x = 6\)
Ski Resort: \(y = 75 + 6 = 81\)
Mt. Winterpark: \(y = 68 + 2(6) = 80\)
When \(x = 7\)
Ski Resort: \(y = 75 + 7 = 82\)
Mt. Winterpark: \(y = 68 + 2(7) = 82\)
When \(x = 8\)
Ski Resort: \(y = 75 + 8 = 83\)
Mt. Winterpark: \(y = 68 + 2(8) = 84\)
When \(x = 9\)
Ski Resort: \(y = 75 + 9 = 84\)
Mt. Winterpark: \(y = 68 + 2(9) = 86\)
When \(x = 10\)
Ski Resort: \(y = 75 + 10 = 85\)
Mt. Winterpark: \(y = 68 + 2(10) = 88\)
Hence, the table is:
x ---- Ski Resort ---- Mt. Winterpark
0 --------75 ----------- 68
1 --------76 ----------- 70
2 --------77 ----------- 72
3 --------78 ----------- 74
4 --------79 ----------- 76
5 --------80 ----------- 78
6 --------81 ----------- 80
7 --------82 ----------- 82
8 --------83 ----------- 84
9 --------84 ----------- 86
10 -------85 ----------- 88
(b)
From the table, the amount of snow is the same at the 7th hour and the snow is 82 inches

Suppose the random variable X has mean 10 and variance 3. Find an upper bound for the probability: P (X > 15).
Therefore, the solution to the given problem is that the upper bound for P(X>15) is 3/25
what is a variance?The variance is the difference between the numbers in a set of data, to put it simply. Each number's variability is a statistical statistic that indicates how far off from the mean and from each other number in the set it is.
Here,
Given : mean = 10
varience = 3
Using chebyshevs inequality we have
P(|X-u| ≥ k)≤ \(\sigma^{2}\)/\(k^{2}\)
hence we can have,
=> P(X>15) ≤ 3/\(5^{2}\)
=> P(X>15) ≤ 3/25
Therefore, the solution to the given problem is that the upper bound for P(X>15) is 3/25

When an independent variable in a multiple regression model includes a value of X to a higher power, such as X squared, and this model produces a higher value of R-squared than a linear model, this suggests that the residual plot for the linear equation did not produce a random pattern around the zero line of the residual plot.
True or False
The higher R-squared value of the multiple regression model with the higher order independent variable implies that the linear model is not the best fit and that a more complex model is needed to better explain the data
1. Multiple regression models involve fitting a model that includes one or more independent variables to predict a dependent variable.
2.A value of X to a higher power, such as X squared, for an independent variable in a multiple regression model indicates that the relationship between the independent and dependent variables is not linear.
3. If this model produces a higher value of R-squared than a linear model, it means that it is a better fit for the data.
4. However, it does not necessarily imply that the linear model's residual plot is not randomly distributed around the zero line.

1. The amount M (in trillions of dollars) of mortgage debt outstanding in the United States from 1990
through 2009 can be approximated by the function M = f(0) = 0.0037(t + 14.979), where t = 0
represents the year 1990.
(a) Describe the transformation of the common function f(x) = x2. Then sketch the graph over the
intervalo s t < 19.
(b) Rewrite the function so that t = 0 represents the year 2000. Explain how you got your answer.
(c) Use the model from part (b) to predict the mortgage debt in the year 2014.
The give quadratic function is dilated by the given coefficient, and shifted
horizontally to the left.
(a) The transformation of the common function f(x) are;
f(t) is made more wider than f(x) f(t) is shifted more to the left than the common function f(x).Please find attached the required graph created with MS Excel
(b) Where t = 0, represent the year 2,000 we have;
f(t) = 0.0037·(t + 24.979)²(c) The mortgage debt in the year 2014 is M ≈ $5.622 trillion
Reasons:
The given function is f(t) = 0.0037·(t + 14.979)²
Year 1990 is t = 0
(a) The given common function is; f(x) = x²
The transformation of the quadratic function are;
The coefficient 0.0037 widens the common function such that f(t) is wider
than f(x).
The constant, 14.979 added to the variable, t, shifts the graph of the
common function horizontally to the left.
Therefore;
f(t) is wider and shifted to the left more than the common function f(x)Please find attached the required graph over the interval 0 ≤ t ≤ 19 created with MS Excel.
(b) The amount of mortgage debt in 2,000 is given as follows;
With t' = 0 represent the year 2,000, we have;
At year 1990, t' = -10
Which gives, t' = t + 10
From which we have;
f(t) = 0.0037·(t + 14.979)² = 0.0037·(t' + 10 + 14.979)² = 0.0037·(t' + 24.979)²
Therefore;
The function with t = 0 representing the year 2,000 is presented as follows;
f(t) = 0.0037·(t + 24.979)²
(c) In the year 2014, we have;
t = 2014 - 2000 = 14
Which gives;
f(14) = 0.0037·(14 + 24.979)² ≈ 5.622
The mortgage debt in the year 2014 is M ≈ $5.622 trillion dollars

In statistical inference for categorical data:___________.
a. Normal data is always a condition for inference.
b. Normal data is never one of the inference assumptions.
c. Normal data or large enough total sample size is one of the inference assumptions.
Answer:
b. Normal data is never one of the inference assumptions.
Step-by-step explanation:
A categorical data specifies among two or more groups, which one each observation belongs to, and one or more explanatory variables that can be used to predict this membership.
So, there are two propositions in statistical inference for categorical data
1. That each data in a cell is independent of the others.
2. That samples are randomly drawn.
Thus, there is no room for normality.
In the diagram below of triangle FGH, J is a midpoint of FG and K is a midpointof GH. If JK = 88 - 9x, and FH = 7x – 49, what is the measure of JK?
In this problem we know that tha triangle FGH is similar to JGK because the have the same angles so we know that the rratio between their sides will be a constant so:
so we have that:
\(\frac{88-9x}{7x-49}=\frac{1}{2}\)and we solve for x so:
\(\begin{gathered} 176-18x=7x-49 \\ 176+49=18x+7x \\ 225=25x \\ \frac{225}{25}=x \\ 9=x \end{gathered}\)So finally with the value of X we can calculate JK so:
\(\begin{gathered} JK=88-9(9) \\ JK=88-81 \\ JK=7 \end{gathered}\)Select the correct answer.

Step-by-step explanation:
Given that Roberto has $ 200 in spending money and he wants to buy some video games that cost $ 25.50 each, to determine the number of games he can buy, the following inequality must be resolved:
25.50X = 200
X = 200 / 25.50
