Answer:

An approximately 2 minutes is expected to reach the front of the line

Step-by-step explanation:

Expected value of minutes =

(1/4)^(1/5) + (1 - 1/4)^(1/5)

= (1/4)^0.2 + (3/4)^0.2

= 0.7579 + 0.9441

= 1.702.

≈ 2 minutes

Evgesh-ka [11]

Answer:

Hello! I am also having trouble in algebra! From what I can see so far this is what the problem should look like...

Step-by-step explanation:

A. Yes, it s a linear function because it matches the equation y=mx+b

B. The domain is 1, 2, 3 , 4, and 5. This is because there are 5 services you can choose from. The domain is discrete because you can't have half a service.

C. Because I'm also doing this book (I'm in Algebra 1 in 8th grade), I'm also just learning this! So sorry, but I don't know how to solve this one either... can someone please help?

Thanks! Also, just a tip, if you're having trouble ever again go to slader.com where they have all the answers to any textbook. They also have really good explanations! However, for this one, I didn't understand it on slader so I came on here! Good luck and if anyone can help with C that would be much appreciated.

T = 126 °

S = 180° - 126°
