Kelly uses point p to represent the sum of 3.6 +(-2.4) on the number line. 3.6 + (-2.4) = p

Kelly says that point pis plotted to the right of both 3.6 and -2.4 on the number line because addition means you should move right on the

number line.

• Explain why Kelly's reasoning is incorrect.

• Explain how the location of p on the number line is related to the locations of 3.6 and -2,4 on the number line.

Determine the value of point p.

Naruto is choosing between two venues that will deliver food to his house. with probability 1/3 he will choose ramen mania (r), and with probability 2/3 he will choose sushi (s). if he chooses r, 15 minutes after making the call, the remaining time it takes the food to arrive is exponentially distributed with average 10 minutes. if he orders s, 10 minutes after making the call, the time it takes the food to arrive is exponentially distributed with an average of 12 minutes. given that he has already waited 25 minutes after calling, and the food has not arrived, what is the probability that he ordered from r? i am really stuck on how to set this up, so if you could be extra clear, that would be super ! in advance
