A 140 kN force with a slope of 4 vertical and 7 horizontal is located on the second quadrant. Determine its y- component.
Calculate the magnitude of the force of repulsion between two equal charges of 2.0V separated by a distance of 1m.
Take (1/4"\\lambda\\epsilon\\Omicron"=9x109)
A company has developed a new battery. The engineering department of the company claims that each battery lasts for 200 minutes. In order to test this claim, the company selects a random sample of 100 new batteries so that this sample has a mean of 190 minutes. Given that the population standard deviation is 30 minutes, test the engineering department’s claim that the new batteries run with an average of 200 minutes. Use 1% level of significance.
4)Given that the level of significance is 0.01 or 1%, what is/are the critical values?
5)Using the appropriate formula, what is the computed test statistic? (Input your answer using 3 decimal places, example: 1.234 if positive or -1.234 if the answer is negative) *
6)What is the decision based from the critical value and the computed test statistic
7)What is the conclusion?

A parking garage charges a $2.00 minimum fee to park for up to three hours. The garage charges an additional $0.50 per hour for each hour or part thereof in excess of three hours. The maximum charge for any given 24-hour period is $10.00. Assume that no car parks for longer than 24 hours at a time. Write a program that will calculate and print the parking charges for each of 3 customers who parked their cars in this garage yesterday. You should enter the hours parked for each customer. Your program should print the results in a neat tabular format and should calculate and print the total of yesterday's receipts. The program should use the function calculateCharges to determine the charge for each customer.
