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.
Answer:
- 176
Step-by-step explanation:
2 + 4/5 x 15 - 190
= 2 + (4/5 x 15) - 190
= 2 + (12) - 190
= 2 + 12 - 190
= 14 - 190
= - 176
Answer:
a - 2
Step-by-step explanation:
Perimeter = side 1 + side 2 + side 3
So
6a + 3 = 2(a + 3) + (3a - 1) + side 3
side 3 = (6a + 3) - (2a + 6) - (3a - 1)
side 3 = 6a - 2a - 3a + 3 - 6 + 1 = a - 2
6 pints: 17 pints
It means that there is 6 pints of strawberry ice cream in every 17 pints of ice cream total
