Without Graphing, Is The System Independent, Dependent, Or Inconsistent? (Equation And Answer Choices Are In Comments!)
In statistics, the independent variable is plotted on the x-axis and the dependent variable on the y-axis of a scatter plot, which is used to analyze the relationship between variables. The correlation coefficient determines the strength and direction of this relationship, while the line of best fit predicts values of the dependent variable.
Explanation:In statistics, when analyzing a set of data that consists of two variables, we typically designate one variable as the independent variable and the other as the dependent variable. The independent variable is the one that is presumed to cause or explain changes in the other variable, which is the dependent variable. When these variables are plotted on a graph, the independent variable is placed on the x-axis (horizontal axis), and the dependent variable is placed on the y-axis (vertical axis).
To explore the relationship between two variables, creating a scatter plot is a common first step. This graph will show individual data points representing the pairs of values for the two variables. By inspecting the scatter plot, one might observe whether there is a clear pattern or trend that suggests a relationship. If the points tend to fall along a line, it indicates that there is a linear relationship between the variables.
The next step would be to calculate the line of best fit, also known as the least-squares line, using regression analysis. The equation of this line is typically in the form ŷ = a + bx, where 'a' is the y-intercept and 'b' is the slope. The line of best fit represents the linear relationship between the variables and is used to predict the value of the dependent variable, given a value of the independent variable.
Another important step is to determine the correlation coefficient, often denoted as 'r'. This coefficient measures the strength and direction of the linear relationship between the two variables. A correlation coefficient close to +1 or -1 indicates a strong correlation, while one close to 0 indicates little to no correlation.

Find the marginal cost, marginal revenue, and marginal profit functions. Find all values of x for which the marginal profit is zero.
C(x) = 5x
R(x) = 8x − 0.001x^2
The marginal cost function is MC(x) = 5, the marginal revenue function is MR(x) = 8 - 0.002x, and the marginal profit function is MP(x) = MR(x) - MC(x). The quantity at which the marginal profit is zero is x = 1500.
Explanation:The marginal cost (MC) function represents the change in total cost when one additional unit is produced. It can be calculated by taking the derivative of the total cost function with respect to quantity (x). In this case, the total cost function is given as C(x) = 5x, so the marginal cost function is MC(x) = 5.
The marginal revenue (MR) function represents the change in total revenue when one additional unit is sold. It can be calculated by taking the derivative of the total revenue function (R(x)). In this case, the total revenue function is R(x) = 8x − 0.001x^2, so the marginal revenue function is MR(x) = 8 - 0.002x.
The marginal profit (MP) function represents the change in profit when one additional unit is produced and sold. It can be calculated by subtracting the marginal cost from the marginal revenue: MP(x) = MR(x) - MC(x).
To find all values of x for which the marginal profit is zero, set the marginal profit function equal to zero and solve for x: 0 = MR(x) - MC(x). In this case, 0 = (8 - 0.002x) - 5. Solving for x gives x = 1500, which is the quantity at which the marginal profit is zero.

A point is moving along the graph of a given function such that dx/dt is 2 centimeters per second. Find dy/dt for the given values of x.
y = 9x2 + 5
(a) x = -1
dy/dt =____ cm/sec
(b) x = 0
dy/dt =____cm/sec
(c) x = 3
dy/dt =_____ cm/sec
...?
The rates of change in y for the given values of x are -36 cm/sec, 0 cm/sec, and 108 cm/sec respectively by using the derivative dy/dt = 18*x*dx/dt.
Explanation:This problem is a case of related rates in calculus. Given that dx/dt is constant at 2 cm/sec and the function y = 9x2 + 5, we need to differentiate the function with respect to t to find dy/dt. Solving for dy/dt, you get dy/dt = 18x * dx/dt.
When x = -1, dy/dt = 18*-1*2 cm/sec = -36 cm/sec.When x = 0, dy/dt = 18*0*2 cm/sec = 0 cm/secWhen x = 3, dy/dt = 18*3*2 cm/sec = 108 cm/secSo, the rates of change in y with respect to time for the given values of x are -36 cm/sec, 0 cm/sec, and 108 cm/sec respectively.

They have lunch at the museum’s cafe. Zalia has a sandwich for $5.95, an apple for $1.25 and a drink for $1.69. She is charged tax and also tips her server 15%. If tax is 7.25%, how much did Zalia pay all total for her day at the science museum?
a.
$41.43
b.
$37.68
c.
$36.35
d.
$24.27
The total comes to $37.67, so the closest answer is (b) $37.68.
We will calculate how much Zalia paid for her day at the science museum including admission fees, lunch, and the tax and tip for both of these.
Firstly, let's calculate the total cost of admission for Zalia and her friend:
Admission for one person: $12.50
Admission for two people: $12.50 x 2 = $25.00
Now, let's find the total cost of Zalia's lunch:
Sandwich cost: $5.95
Apple cost: $1.25
Drink cost: $1.69
Total lunch cost before tax and tip: $5.95 + $1.25 + $1.69 = $8.89
Next, we add the tax:
Tax for admission: $25.00 x 7.25% = $1.81
Tax for lunch: $8.89 x 7.25% = $0.64
Total tax: $1.81 + $0.64 = $2.45
Now, we calculate the tip for the lunch:
Tip: $8.89 x 15% = $1.33
Finally, add everything up to get the total amount Zalia paid:
Total cost without tax and tip: $25.00 + $8.89 = $33.89
Total tax and tip: $2.45 + $1.33 = $3.78
Grand total: $33.89 + $3.78 = $37.67
Examining the provided options, we can see that the closest amount to our calculation is $37.68, considering the possibility of a rounding difference in the final tax and tip calculations. Thus, the correct answer is (b) $37.68.

The ratio of the amount of money Kim gets to the amount of money Mollley gets is 2:5
Kim gets £105 less than Molly gets
What percentage of the £385 does Laura get ?
With working out
To find out what percentage of the £385 Laura gets, we need to determine the amounts that Kim and Molly get. By solving equations and subtracting their amounts from the total, we find that Laura gets approximately 45.45% of the £385.
Explanation:To find out what percentage of the £385 Laura gets, we need to first find out the amounts that Kim and Molly get. Let's assume that Kim gets x amount. According to the ratio, Molly gets 5x amount. From the information given, we know that Kim gets £105 less than Molly, so we can write the equation: 5x - x = £105. Solving this equation, we get x = £35. Therefore, Kim gets £35 and Molly gets 5x £35 = £175. Now, to find out the amount Laura gets, we subtract the amounts of Kim and Molly from the total amount: £385 - £35 - £175 = £175. So Laura gets £175. To find out the percentage, we divide the amount Laura gets by the total amount (£385) and multiply by 100: (175 / 385) * 100 = 45.45%. Therefore, Laura gets approximately 45.45% of the £385.

The sum of the measures of the interior angles of a polygon is five times the sum of the measures of its exterior angles, one angle at each vertex. How many sides does the polygon have? ...?
The sum of exterior angles for any polygon is 360 degrees. Given that the sum of the interior angles is five times this, that's 1800 degrees. By using the formula (n-2)*180 = Sum of Interior angles, we can conclude that the polygon has 12 sides.
Explanation:This question revolves around the properties of interior and exterior angles of polygons. The sum of the exterior angles of any polygon is always 360 degrees. Now, given that the sum of the measures of the interior angles of the polygon is five times the sum of the measures of its exterior angles, this can be interpreted as the sum of the interior angles being 5*360 = 1800 degrees.
To find the number of sides the given polygon has, we can use the formula (n-2)*180 = Sum of Interior angles, where n is the number of sides. Rearranging the formula, n = sum of interior angles / 180 + 2 => n = 1800 / 180 + 2 = 12. Therefore, the polygon has 12 sides.
