The probability that it will snow in a certain town on January 1st is 0.29 find the probability that in a given year it will not
Mashutka [201]

Answer:

0.71


Step-by-step explanation:

The probability is a chance of an event happening. The probability of assured event is 100% or 1.

If there is no chance of an event happening the probability is zero (0).

The probability of snowing = 0.29

The probability of not snowing = 1 - 0.29

                                                   = 0.71

What is an explicit formula for the geometric sequence 64,16,4,1,... where the first term
olya-2409 [2.1K]

Answer:

A

Step-by-step explanation:

The explicit formula for a geometric sequence is

f(n) = f(1) (r)^{n-1}

where f(1) is the first term and r the common ratio

Here f(1) = 64 and r = \frac{f(2)}{f(1)} = \frac{16}{64} = \frac{1}{4} , then

f(n) = 64 (\frac{1}{4}) ^{n-1} → A

Question 20: Please help what are sin x and cos x?
sweet [91]

Answer:

A is the correct answer.

Step-by-step explanation:

\tan x =   \frac{6}{8}  =  \frac{opposite \: side \: to \:  \angle \: x}{adjacent \: side \: to \:  \angle \: x}  \\  \\ hypotenuse  \\ =  \sqrt{ {(opp. \: side)}^{2} +  {(adj. \: side)}^{2}  }  \\  =  \sqrt{ {6}^{2} +  {8}^{2}  }  \\  =  \sqrt{36 + 64}  \\  =  \sqrt{100}  \\  = 10 \\  \\ \because  \sin (x) =  \frac{opposite \: side \: to \:  \angle \: x}{hypotenuse}  \\  \\   \huge{ \red{ \boxed{\therefore \: \sin (x) =  \frac{6}{10}}}}  \\  \\ \cos (x) =  \frac{adjacent \: side \: to \:  \angle \: x}{hypotenuse}  \\  \\  \huge{ \purple{ \boxed{\therefore \: \cos (x) =  \frac{8}{10} }}} \\

Thus, option A is the correct answer.
