Given the two planes x - y + 2z = 0 and 3x + 2y - 6z + 4 = 0. Find a parametric equation for the intersection.
Through careful record keeping, you have the times to burn out of 100 Bright brand light bulbs. The average time to burn out is 200 hours, with a standard deviation of 12 hours. Give a 95% confidence interval for the mean time to burn out of this brand of light bulb.
If the systolic pressure for a certain group of obese people has mean of 132 and a standard deviation of 8, find the probability that a randomly selected person will have the following blood pressure. Assume the variable is normally distributed.

The leader of the jeepney drivers’ association claims that the average daily take-home pay of all jeepney drivers in Pasay city is Php 400.00. A random sample of 100 jeepney drivers in Pasay city was interviewed and the average daily take-home pay of these drivers is found to be Php 425. Use a 0.05 level of significance and assume the standard deviation is Php 92.
Ծ = 92 Ẋ = 425 ﬠ = 400 n = 100 level of significance = 0.05
1. State the hypothesis
Ho: u = 400
Ha: u ‡ 400
2. Type of test: Two-tailed test
3. Critical Value
4. Test statistics
5. Reject or accept the null hypothesis
Write a complete C++ program that • Creates a 12 element integer array containing elements between 0 and 20 using the rand function. • After creating the array, sort it using any of the sorting methods then ask the user to guess a number between 0 and 20. • To search if the number is in the array, create a menu: 1: Linear 2: Binary. The different search algorithms are to be created in separate Functions. • int LinearSearch(int list[], int size, int value) • int BinarySearch(int list[], int size, int value) • if it is guessed number is found the chosen function should return the index of the value to the main function, then the main function should sshow index and value to the user
