Question

некоторое количество кнопок выпало с коробки: 23 упали острием вверх, 28 – острием вниз. найди относительную частоту кнопок, которые упали острием вверх с точностью до двух знаков после запятой. ответ: .

Answer 1

Ответ:

Объяснение:

Всего выпало 23 + 28 = 51 кнопка.

Острием вверх упало 23 из них.

Относительная частота равна 23/51 = 0,45

Answer 2

Finding the Relative Frequency of Buttons that Fell Upside Down

To find the relative frequency of buttons that fell upside down, we need to calculate the ratio of the number of buttons that fell upside down to the total number of buttons.

According to the information provided, 23 buttons fell upside down, while 28 buttons fell with the pointy end down. To find the relative frequency, we can use the following formula:

Relative Frequency = Number of buttons that fell upside down / Total number of buttons

Plugging in the values, we get:

Relative Frequency = 23 / (23 + 28)

Calculating this expression, we find that the relative frequency of buttons that fell upside down is approximately 0.450 when rounded to two decimal places.

Please note that the information provided does not specify the total number of buttons in the box, so we cannot provide an exact value for the relative frequency. However, based on the given information, we can calculate the relative frequency using the provided numbers.
