Question

Один из участников соревнования парашютистов совершил 8 прыжков :3 прыжка с высоты 1000 метров,2 прыжка с высоты 800 метров,3 прыжка с высоты 600 метров.Найти среднюю высоту его прыжка ?Срочно!

Answer 1

Скорее всего их надо все сложить 1000х3+2х800+3х600=6400
6400:8=800
может так?

Answer 2

1.3*1000+2*800+600*3=6400
2. 3+2+3=8
3. 6400/ 8=800м

Answer 3

Calculating the Average Parachute Jump Height

To find the average height of the parachutist's jumps, we can calculate the weighted average based on the number of jumps from each height.

The parachutist made: - 3 jumps from a height of 1000 meters - 2 jumps from a height of 800 meters - 3 jumps from a height of 600 meters

To calculate the average height, we can use the following formula:

Average Height = (Total distance traveled) / (Total number of jumps)

Let's calculate the average height based on the given information.

Calculation

The total distance traveled can be calculated by multiplying the number of jumps at each height by the respective height and then summing these values.

- Total distance from jumps at 1000 meters: 3 jumps * 1000 meters = 3000 meters - Total distance from jumps at 800 meters: 2 jumps * 800 meters = 1600 meters - Total distance from jumps at 600 meters: 3 jumps * 600 meters = 1800 meters

Total distance traveled = 3000 meters + 1600 meters + 1800 meters = 6400 meters

The total number of jumps is 3 + 2 + 3 = 8 jumps.

Average Height = 6400 meters / 8 jumps = 800 meters

Answer

The average height of the parachutist's jumps is 800 meters.
