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
Answer:
3.2
Step-by-step explanation:
x² + xy = 20
Take the derivative with respect to time:
2x dx/dt + x dy/dt + y dx/dt = 20
(2x + y) dx/dt + x dy/dt = 20
Given x = -5, y = 1, and dx/dt = -4:
(2(-5) + 1) (-4) + (-5) dy/dt = 20
(-10 + 1) (-4) − 5 dy/dt = 20
36 − 5 dy/dt = 20
5 dy/dt = 16
dy/dt = 3.2
