Solution Steps

Step 1: Identify the Data

The data provided is the number of books read by nine students last summer:
\[ 6, 6, 9, 6, 9, 3, 1, 1, 6 \]

Step 2: Find the Maximum and Minimum Values
  • The maximum value in the data is \( 9 \).
  • The minimum value in the data is \( 1 \).
Step 3: Calculate the Range

The range is calculated as the difference between the maximum and minimum values:
\[ \text{Range} = \text{Maximum} - \text{Minimum} = 9 - 1 = 8 \]

Final Answer

The range is \(\boxed{8}\).

Use the Laplace transform to solve the following initial value problem: y'' - 4y' + 20y = 0 y(0) = 0, y'(0) = 4 a. Using Y for the Laplace transform of y(t), i.e., Y = Ly(t), find the equation you get by taking the Laplace transform of the differential equation b. Now solve for Y(s) = 4 / (s-2)^2 + 4^2 c. By completing the square in the denominator and inverting the transform, find y(t) = e^(2t) sin(4t)

First Name Kendra Last Name - Lab 1-Measure the Gravity (Weight) of your toy- car. Mass (g) Mass (kg) Gravity (weight) / N 1.Measure by triple beam 80.08 0.08 kg 0.08 kg(9.8 m / s) 2. If move your toy-car to the Moon, Its mass will be the same (the same/bigger/smaller). And its Weight (Gravity) will be smaller (the same/bigger/smaller). Why? Lab 2-Explore the characteristics of Friction Force 1. Make your car to move at different surface with constant velocity. (The friction force equals the spring force) 1. Conclusion: the different surface add different friction 2. Add different weight (More weight causes bigger normal force). Move the car on the lab table with constant "V" and record the friction force. 2. Conclusion 3. Compare the Sliding Friction and the Rolling Friction. 3. The Rolling friction is than the sliding friction.
