It has exactly ONE solution.
One solution= 2 lines intercect, and the point they intersect is the solution.
infinite solutions= equations are equivalent
no solutions= lines never intersect
Answer:
P(0≤T≤400)=0.3296
Step-by-step explanation:
we know probability density function is
probability that bulb will fail within first 400 hours
P(0≤T≤400)=
P(0≤T≤400)=
=
=
=1-0.67032 = 0.3296
so about 32.96 % bulb will fail within 400 hrs.
X=10 I think I’m not sure
