Question

Три столяри протягом 7 годиного робочого дня виготовляли деталі 1 столяр виготовляє 1 деталь за 15 хв. другий -за 17.5хв. а третій - за 20хв. Скласти таблицю статистичного розподілу виготовлення деталів за день. Визначити скільки часу всередньому витрачалось на виготовлення 1 деталі

Answer 1

1) Рабочий  день
7 ч * 60 = 420 мин
2) 420 мин : 15 мин/шт = 28 дет - изготавливает первый
3) 420 : 17,5 = 24 шт -  второй
4) 420 : 20 = 21 шт - третий
5)  28 + 24 + 21 = 73 шт -  все трое за рабочий день
6) 420 мин : 73 шт ≈ 5,75 мин ≈ 5 мин 45 с - среднее время на 1 дет.- ОТВЕТ

Answer 2

Task: Creating a Statistical Distribution Table for Manufacturing Parts

To create a statistical distribution table for the manufacturing of parts by three carpenters during a 7-hour workday, we need to consider the time taken by each carpenter to produce one part. Let's analyze the given information and calculate the average time spent on manufacturing one part.

According to the information provided: - Carpenter 1 takes 15 minutes to produce one part. - Carpenter 2 takes 17.5 minutes to produce one part. - Carpenter 3 takes 20 minutes to produce one part.

Statistical Distribution Table for Manufacturing Parts

To create the statistical distribution table, we will calculate the number of parts produced by each carpenter within the given 7-hour workday. We will assume that each carpenter works continuously without any breaks.

| Carpenter | Time per Part (minutes) | Parts Produced in 7 Hours | |-----------|------------------------|--------------------------| | 1 | 15 | | | 2 | 17.5 | | | 3 | 20 | |

To calculate the number of parts produced by each carpenter in 7 hours, we can use the following formula:

Number of parts produced = (Total work time in minutes) / (Time per part)

For Carpenter 1: - Total work time in minutes = 7 hours * 60 minutes/hour = 420 minutes - Number of parts produced by Carpenter 1 = 420 minutes / 15 minutes per part = 28 parts

For Carpenter 2: - Total work time in minutes = 7 hours * 60 minutes/hour = 420 minutes - Number of parts produced by Carpenter 2 = 420 minutes / 17.5 minutes per part = 24 parts

For Carpenter 3: - Total work time in minutes = 7 hours * 60 minutes/hour = 420 minutes - Number of parts produced by Carpenter 3 = 420 minutes / 20 minutes per part = 21 parts

Completed Statistical Distribution Table

| Carpenter | Time per Part (minutes) | Parts Produced in 7 Hours | |-----------|------------------------|--------------------------| | 1 | 15 | 28 | | 2 | 17.5 | 24 | | 3 | 20 | 21 |

Average Time Spent on Manufacturing One Part

To calculate the average time spent on manufacturing one part, we need to find the total time spent by all carpenters and divide it by the total number of parts produced.

Total time spent on manufacturing = (Number of parts produced by Carpenter 1 * Time per part) + (Number of parts produced by Carpenter 2 * Time per part) + (Number of parts produced by Carpenter 3 * Time per part)

Total time spent on manufacturing = (28 * 15) + (24 * 17.5) + (21 * 20) = 420 + 420 + 420 = 1260 minutes

Total number of parts produced = Number of parts produced by Carpenter 1 + Number of parts produced by Carpenter 2 + Number of parts produced by Carpenter 3

Total number of parts produced = 28 + 24 + 21 = 73 parts

Average time spent on manufacturing one part = Total time spent on manufacturing / Total number of parts produced

Average time spent on manufacturing one part = 1260 minutes / 73 parts ≈ 17.26 minutes

Therefore, on average, it takes approximately 17.26 minutes to manufacture one part.
