Answer:
3 hours.
Step-by-step explanation:
Since they are heading away from each other, their relative velocity is 60+55 = 115 mph. 345 miles/115 mph = 3 hours.
Check by plugging in. In 3 hours, Max travels 3 * 60 mph = 180 miles from the starting point. Min travels 3 * 55 mph = 165 miles in the other direction from the starting point. The total distance is 165 + 180 = 345 miles.
Answer:

Answer:
666
Step-by-step explanation:
From this question,
a = 1-99%
a = 1-0.99
a = 0.01
5% = z(0.05) = 2.58 when we check the standard normal table
Therefore we calculate n as:
n = (z/E)²*p*1-p
Z = 2.58
E = 0.05
P = 0.5
1-p = 0.5
(2.58/0.05)²x0.5x0.5
= 51.6²x0.5x0.5
= 665.64
Therefore n is approximately 666.
You do what I’d 9-3 , 8-0 , then combined it and you will get the right answer
