A 30ft ladder weighing 100 lb having its center of the mass one-third of the way up from the bottom rests against a smooth wall so that it makes an angle of with the ground. If the coefficient of friction between the ground and the ladder is 0.4, how high can a 150-lb man go before the ladder slips?
Show that X^2 + Y^2 + Dx + Ey + F=0 represents a circle of positive radius if and only if D^2 + E^2 - 4F > 0.
Create two buttons with button text "Button-1" and "Button-2" and put them in a frame using FlowLayout. Use pack () method to discard any whitespaces while putting those buttons in the frame. When you click on the "Button-1" it should display a message ("You clicked Button-1") in a popup window and when you click on the "Button-2" it should display a message ("You clicked Button-2")
Suppose you are given a Customer’s list registered as executive members in a storeand you are required to implement an array-based Customerlist. Each Customerin the list hasname, customerID, Contactand membership Category (category can be regular and VIP). Implement different functionsfor entering the data (likeconstructor (for setting to default values),setName, setId, etc.). You also need to implement the following function related to the array.insertCustomer(): It has 2 options•Asking the user for indexand then insert the Customerat that indexAND•Asking the user for the ID of the customerwhere the new Customeris to be added (New Customershould be added at the index of the CustomerwhoseIDis entered)oIf the list is full,it should create a larger list (new size should be entered by the user), copy all the data in it and make insertion as instructedoInsertion will only be made if the IDof the new Customerdoesn’t exist in the listdeleteCustomer()
Write a Linux shell script that performs the following tasks:
a. Provide a mystery integer between 1 to 10.
b. Using “while” loop, allow the user to guess the random number until the user
got it right.
c. If the user’s entered number is lower or greater than the random number,
notify the user to guess higher or lower respectively.
d. If the user enters any number out of the 1 to 10 range, notify the user to
enter in the correct number range.
e. Display a congratulatory message along with the random number if the user
guessed it correctly.
1. The guaranteed average life of a certain type of electric light bulbs is 1000 hours with a standard deviation of 125 hours. It is decided to sample the output to ensure that 90 percent of the bulbs do not fall short of the guaranteed average by more than 2.5%. What must be the minimum size of the sample?
n = 68, ¯x=75, and σ = 8. The sample population is normally distributed. Find the 99% interval estimate for µ.
A sample of 100 Grade 9 students’ ages have been obtained to estimate the mean age of all Grade 9 students. ¯x=16 years and the population variance is 0.75 years. Find the 95% confidence interval for µ.
