≈ 0.2526
Step-by-step explanation:
<u>The number of combinations of 4 out of 8:</u>
- 8C4 = 8!/(4!(8-4)!)= 8*7*6*5/(1*2*3*4)= 70
<u>Success factor is: </u>
<u>and failure factor is: </u>
<u>Probability:</u>
Answer:

Step-by-step explanation:
put them both in exponential form and then since they are both base 6, you can add the exponents.

The answer to this question is 22
z = 7√2 cos(7/8π) + 7√2i sin(7/8π) = 7√2e^(i7/8π)
B.) 85
They are alternate interior angles so they are the same degree.
