Question

для проверки всхожести семян огурцов их посеяли в 5 ящиков по 100 штук. В первом ящике взошло 93 во втором 89 в третьем 97 в четвертом 96 и в пятом 90 семян .Какова средняя всхожесть семя? ПОМОГИТЕ ПОЖАЛУСТА!

Answer 1

Из всех посаженных семян (500шт) взошло всего 465

решая пропорцию:

465 составляет от 500 - 93%

 

или так:

средняя всхожесть в каждом ящике: 93%, 89%, 97%, 96% и 90%

Находим среднюю:

(93+89+97+96+90) : 5 = 465:5=93%

Answer 2

Calculation of Seed Germination Rate

To calculate the average germination rate of the cucumber seeds, we need to add up the number of seeds that germinated in each box and divide it by the total number of seeds planted.

Let's calculate the average germination rate step by step:

1. Count the number of seeds that germinated in each box: - Box 1: 93 seeds germinated - Box 2: 89 seeds germinated - Box 3: 97 seeds germinated - Box 4: 96 seeds germinated - Box 5: 90 seeds germinated

2. Add up the total number of germinated seeds: - Total germinated seeds = 93 + 89 + 97 + 96 + 90 = 465 seeds

3. Calculate the average germination rate: - Average germination rate = (Total germinated seeds / Total number of seeds planted) * 100 - Average germination rate = (465 / (5 * 100)) * 100 = 93%

Therefore, the average germination rate of the cucumber seeds is 93%.

Please note that the calculation assumes that all the seeds were viable and capable of germination. However, factors such as seed quality, storage conditions, and environmental factors can affect the germination rate.
