Question

47 Ячмінь вирощували на трьох однакових ділянках площею 1 га кожна. На першій ділянці вро- жайність становила 12 т зерна з гектара, на другій землі 13 т, а на третій 11 т. Знайди середню врожайність - — ячменю на трьох ділянках. -​

Answer 1

Ответ:

12 тонн

Пошаговое объяснение:

Щоб знайти середнє арифметичне треба додати подані числа і поділити їх на їх кількість:

(12+13+11)÷3=36÷3=12

Answer 2

Calculation of Average Yield of Barley on Three Plots

To find the average yield of barley on the three plots, we need to calculate the total yield and divide it by the total area.

Let's denote the yield on the first plot as Y1, the yield on the second plot as Y2, and the yield on the third plot as Y3. The area of each plot is 1 hectare.

According to the information provided, the yield on the first plot is 12 tons per hectare, the yield on the second plot is 13 tons per hectare, and the yield on the third plot is 11 tons per hectare.

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

Average Yield = (Y1 + Y2 + Y3) / 3

Substituting the given values, we get:

Average Yield = (12 + 13 + 11) / 3

Calculating the sum of the yields:

Average Yield = 36 / 3

Simplifying the expression:

Average Yield = 12 tons per hectare

Therefore, the average yield of barley on the three plots is 12 tons per hectare.
