Answer:

x = 58

Step-by-step explanation:

So, rotate the triangle so the 61-degrees corner is on the bottom left. We know that the other bottom angle is equal since it's an isosceles triangle. Add 61 + 61, to get 122 degrees. Subtract 122 from the sum of angles, 180 to get 58 degrees.

Considering the opposite of the rational number -1/2, the location of the snail is represented by the number 1/2.

<h3>What is the missing information?</h3>

This problem is incomplete, but researching it on a search engine, we have that:

  • The fish is located at -1/2 feet.
  • The snail is located at the opposite location of the fish.

<h3>What is the opposite of a rational number?</h3>

The opposite of a rational number a is given by -a, that is, it is the number with the opposite signal.

Hence, the <u>opposite of -1/2 is 1/2</u>, and the location of the snail is represented by the number 1/2.

inn [45]

Answer:

Follows are the solution to the given point:

Step-by-step explanation:

For option A:

In the first point let z be the number of heads which is available on the first two trails of tosses so, the equation is:

P(X=k | z=2 ) = \begin{pmatrix} 10-2\\ k-2\end{pmatrix} (\frac{1}{2})^{k-2} (\frac{1}{2})^{10-k}

                         = \begin{pmatrix} 8\\k-2\end{pmatrix} (\frac{1}{2})^{k-2} (\frac{1}{2})^{10-k} \ \ \ \ \ \ \ \ \  \ \\\\

                                                                                                       k= 2,3..........10For option B:

P(X=k | X \geq 2 ) =  \sum^{10}_{i=2}  \begin{pmatrix} 10-i\\ k-i\end{pmatrix} (\frac{1}{2})^{k-i} (\frac{1}{2})^{10-k}

                                                                                                k= 2,3, 4.........10
