suppose abby tracks her travel time to work for 60 days and determines that her mean travel time, in minutes, is 35.6. assume the travel times are normally distributed with a standard deviation of 10.3 minutes. determine the travel time x such that 17.36% of the 60 days have a travel time that is at least x
Answers
The travel time x is 41.162 min such that 17.36% of the 60 days have a travel time that is at least x.
We have to determine the travel time such that 17.36% of the 60 days have a travel time that is at least.
Total work days to work = 60 days
The travel mean time = 35.6
Standard deviation = 10.3
For normal distribution,
P(X < A) = P(Z < (A - mean)/standard deviation)
P(X > x) = 0.2946
P(X < x) = 1 - 0.2946 = 0.7054
P(Z < (x - 35.6)/10.3) = 0.7054
Take the z value that corresponds to 0.7054 in the table of the standard normal distribution.
(x - 35.6)/10.3 = 0.54
x = 41.162 min

A reaction with a calculated yield of 9.23 g produced 7.89 g of product. What is thepercent yield for this reaction?
Answers
The required percentage yield for the reaction when theoretical yield and actual yield are given is calculated to be 85.5 %.
The maximum mass that can be generated when a particular reaction occurs is referred to as theoretical yield.
Theoretical yield is given as mt = 9.23 g
The actual amount of product recovered is given as ma = 7.89 g
We must comprehend that in order to calculate the reaction's percent yield, we must divide the total amount of product recovered by the utmost amount that can be recovered. If we multiply by 100%, we can represent this fraction as a percentage.
Percentage yield = ma/mt × 100 = 7.89/9.23 × 100 = 85.5 %

One can set up a spreadsheet to compute the iterations of Euler's method for approximating solutions to second-order ODEs. true or false
Answers
The statement "one can set up a spreadsheet to compute the iterations of Euler's method for approximating solutions to second-order ODEs" is true because this method provides a numerical solution to differential equations by iteratively updating the variables based on the given differential equation.
A spreadsheet can be used to organize and calculate these iterations, making it easier to approximate the solutions to second-order ODEs.
To set up a spreadsheet for Euler's method to approximate solutions to a second-order ODE, one would need to follow these steps:
Define the ODE and its initial conditions (i.e., the values of the dependent variable and its derivative at some starting point).Choose a step size (i.e., the size of the intervals between each successive approximation).Use Euler's method to compute the next approximation of the solution at each step, using the previous approximation and the derivative of the ODE at that point.Store each approximation in a separate cell of the spreadsheet.Repeat the process until the desired number of approximations has been computed.The spreadsheet would allow you to easily perform the iterative calculations required by Euler's method, and to visualize the behavior of the solution over time.

Sketch the graph of the equation with a double root at -2
Answers
The graph of the equation with a double root at -2 is a parabola that touches the x-axis at -2 and opens upward. It represents a quadratic function that has a repeated solution at x = -2.
When a quadratic equation has a double root at a particular value, it means that the graph of the equation touches the x-axis at that point but does not cross it. In this case, the double root is at -2, which means that the graph touches the x-axis at x = -2.
Since the root is a double root, the graph is a parabola that opens upward. This means that as you move away from the double root in either direction, the graph rises. However, it does not cross the x-axis again. The vertex of the parabola is located at the double root, which in this case is (-2, 0).
By sketching the graph, you can visually represent the behavior of the equation and understand how it relates to the given double root.

Suppose that a new employee starts working at $7.32 per hour and receives a 4% raise each year. After time t, in years, his hourly wage is given by the equation y = $7.32(1.04). Find
the amount of time after which he will be earning $10.00 per hour.
After what amount of time will the employee be earning $10.00 per hour?
years (Round to the nearest tenth of a year as needed.)
HELP PLEASE
Answers
Using the equation \(y = $7.32(1.04)^t\), the amount of time after which the employee will be earning $10.00 is about 9.64 years, or approximately 9 years and 8 months.
What is an equation?
A mathematical definition of an equation is a claim that two expressions are equal when they are joined by the equals sign ("=").
We can start by setting up the equation for the employee's hourly wage y after t years -
\(y = $7.32(1.04)^t\)
We want to find the amount of time t after which the employee will be earning $10.00 per hour, so we can set y equal to 10 and solve for t -
\(10 = $7.32(1.04)^t\)
Dividing both sides by $7.32, we get -
\(1.367 = 1.04^t\)
Taking the natural logarithm of both sides, we get -
\(ln(1.367) = ln(1.04^t)\)
Using the property of logarithms that \(ln(a^b) = b ln(a)\), we can simplify the right-hand side -
ln(1.367) = t ln(1.04)
Dividing both sides by ln(1.04), we get -
t = ln(1.367)/ln(1.04) ≈ 9.64
Therefore, the employee will be earning $10.00 per hour after about 9.64 years.

I-77 I-85 Airport
X=16 X=35 X=40
Y=28 Y=10 Y=18
W=26,000 W=12,000 W=10,000
Determine the best site location using the center-of-gravity technique
Subject - Logistics management
Answers
Using the center-of-gravity technique, the best site location for the new distribution center in Charlotte is determined to be at coordinates (X, Y) = (27.92, 19.08).
The center-of-gravity technique is used to find the optimal location for a facility based on the distribution of demand. In this case, we will calculate the weighted average of the coordinates (X, Y) of the three sites, with the weights being the number of weekly packages flowing to each site.
To calculate the X-coordinate of the center of gravity, we use the formula:
Xc = (X1 * W1 + X2 * W2 + X3 * W3) / (W1 + W2 + W3)
Similarly, for the Y-coordinate:
Yc = (Y1 * W1 + Y2 * W2 + Y3 * W3) / (W1 + W2 + W3)
Substituting the given values:
Xc = (16 * 26000 + 35 * 12000 + 40 * 10000) / (26000 + 12000 + 10000) ≈ 27.92
Yc = (28 * 26000 + 10 * 12000 + 18 * 10000) / (26000 + 12000 + 10000) ≈ 19.08
Therefore, the best site location for the new distribution center in Charlotte is approximately at coordinates (X, Y) = (27.92, 19.08) based on the center-of-gravity technique.

The number of the player who signed up for a soccer league dropped out is 26 if the football season 13% of the players who signed up for a soccer league dropped out.
What is the percentage?It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
It is given that:
During a football season, 13% of the players who signed up for a soccer league dropped out.
Percentage of a football player who finished the season = 100 - 13
Percentage of a football player who finished the season = 87%
Let the total number of a football player is x
87% of x = 174
(87/100)x = 174
0.87x = 174
x = 174/0.87
x = 200
A total number of players who signed up for a soccer league dropped out:
= 200 - 174
= 26
