The probability of obtaining nine heads in a row when flipping a coin is

Answer: The probability is about 0.2%.

The probability of flipping heads one time is 0.5, 50% or 1/2.

To flip heads 9 times in a row, we have to multiply 1/2 by itself 9 times.

(1/2)^9 = 1/512 or about 0.2%

It should only happen once every 512 times.

Which steps will generate an expression equivalent to 17(+5)
Bingel [31]

For this case we must indicate an expression equivalent to:

17 (x + 5)

By definition we have that the distributive property establishes that:

a (b + c) = ab + ac

Then, applying the property to the given expression we have:

17 (x + 5) = 17 * x + 17 * 5 = 17x + 85

Thus, an equivalent expression is:

17x + 85

ANswer:

17x + 85

MAVERICK [17]

Answer:

\sf x =\dfrac{2}{3}

Explanation:

\sf \rightarrow \dfrac{x+1}{2} = \dfrac{7x-3}{2}

cross multiply

\sf \rightarrow 2(x+1) = 2(7x-3)

divide both sides by 2

\sf \rightarrow x + 1 = 7x-3

isolate variables

\sf \rightarrow x -7x = -3-1

simplify

\sf \rightarrow -6x = -4

divide both sides by -6

\sf \rightarrow \dfrac{-6x}{-6}  = \dfrac{-4}{-6}

simplify

\sf \rightarrow x =\dfrac{2}{3}
