Xác suất xảy ra môt sự kiện là 0.3. Xác suất để sự kiện đó không xảy ra là?

Mathematics
1 answer:
hodyreva [135]3 years ago
3 0

Câu trả lời:

0,7

Giải thích từng bước:

Xác suất để một sự kiện xảy ra = 0,3

Cho sự kiện = A

P (A) = 0,3

Xác suất mà sự kiện không xảy ra có thể thu được bằng cách sử dụng quy tắc bổ sung;

P (A ') = 1 - P (A)

Vì thế,

P (A ') = 1 - 0,3 = 0,7

17, 13, 9,5...<br> determine the sequence
ValentinkaMS [17]

This is an arithmetic sequence because we are adding the same amount each time. In this case, we are adding -4 to each term to get the next term

17 + (-4) = 13

13 + (-4) = 9

9 + (-4) = 5

and so on. The starting term is a_1 = 17

The common difference is d = -4

The nth term of the arithmetic sequence can be found by this formula

a_n = a_1 + d(n-1)\\\\a_n = 17 + (-4)(n-1)\\\\a_n = 17 - 4n + 4\\\\a_n = -4n+21

For instance, if n = 2, then,

a_n = -4n+21\\\\a_2 = -4(2)+21\\\\a_2 = -8+21\\\\a_2 = 13

which matches up with the second term listed.

A circle has a radius of 10 inches. Find the approximate length of the arc intersected by a central angle of 2π/3
Aleksandr-060686 [28]

Answer: Option 'C' is correct.

Step-by-step explanation:

Since we have given that

Radius of circle = 10 inches

Central angle is given by

\frac{2\pi }{3}

As we know the formula for " Length of an arc " :

Length of arc is given by

l=r\theta\\\\l=10\times \frac{2\pi}{3}\\\\l=10\times \frac{2}{3}\times \frac{22}{7}\\\\l=20.95\ inches

Hence, length of an arc is 20.95 inches.

Hence, Option 'C' is correct.
