Answer:
Third one
Step-by-step explanation:
<u>Two </u>things to solve 3x+9 <= 15
3x <= 6
<u> x <= 2</u>
<u> and</u> - (3x+ 9) <= 15
- 3x - 9 <= 15
- 3x <= 24
3x >= -24
<u> x > = - 8 </u>
<u />
<u />
<u>s o -8 <= x <= 2 </u>
Answer:
A.) The probability that the missile is not detected by any of n sets = (1-0.9)^n = 0.1^n.
Where it's opposite will be that the missile is detected by atleast 1 of the sets. Which will be equals to 1-(0.1)^n.
B.) 0.999= 1-(0.1)^n
Here n=3
For, 0.999999=1-(0.1)^n
n=6.
C.) If n=5
5C4*(0.9)^4*(0.1)^1= 0.32805
