Answer:
4 stations
Step-by-step explanation:
If we need to be at least 98% certain that an enemy plane flying over will be detected by at least one station, we must ensure that there is at most a 2% chance that no radar stations detect the plane.
The probability that a single radar station does not detect the plane is 0.35.
For n radar stations:
Rounding up to the next whole station, at least 4 stations are needed.
Let x be the number of days you need to work.
Your goal is to achieve at least 10 000 steps.
x + 5274 ≥ 10 000
x ≥ 10 000 - 5274
x ≥ 4726
-------------------------------------------------------------------------------------------------------
You need to take at lest another 4726 steps to achieve the goal.

X = 7 + staci since 7 more cats added to x is stacis amount
