Two schools, jefferson hills east and jefferson hills west, are taking a field trip. a total of 408 students from jefferson hills east will be going in 3 vans and 6 buses. a total of 516 from jefferson hills west will be going in 6 vans and 7 buses. each can has the same number of passengers and each bus has the same number of passengers. wrote a system of equations that represents this problem situation. let x represent the number of students in each van, and let y represent the number of students in each bus.

Use this data in the problem below. follow the steps carefully. round to the nearest tenth. lot 3: week 1: 345 week 2: 340 week 3: 400 week 4: 325 step 1. jim enters the data and calculates the average or mean. step 2. jim calculates the deviation from the mean by subtracting the mean from each value. step 3. jim squares each deviation to remove negative signs. step 4. jim sums the squares of each deviation and divides by the count for the variance. step 5. jim takes the square root of the variance to find the standard deviation.

3. find the radius of circle p.4. find y.
