Answer:
The probability of a bulb lasting for between 480 and 526 hours=0.74454
Step-by-step explanation:
We are given that
Standard deviation of the lifetime,hours
Mean, hours
We have to find the probability of a bulb lasting for between 480 and 526 hours.
Hence, the probability of a bulb lasting for between 480 and 526 hours=0.74454
Answer:
The given statement:
You cannot bisect an angle using paper folding constructions is a False Statement.
Step-by-step explanation:
The construction of a angle bisector with the help of paper folding is done by:
- Draw a angle ACB on a piece of paper such that the ray CB lie on the base.
- Fold the paper in such a way that ray AC falls along the ray CB.
- draw the line along the crease that is formed on the paper starting from point C.
- So, the ray so formed is the angle bisector of the angle ACB.
The answer is -2, hopes this helps

Answer:
a) 0.1600
b) 0.3654
Step-by-step explanation:
a) The samples are independents, so:
P(O1∩O2)=P(O1).P(O2)=0.40*0.40=0.1600
b) P(A1∩A2)+P(B1∩B2)+P(AB1∩AB2)+P(O1∩O2)=
P(A1).P(A2)+P(B1).P(B2)+P(AB1).P(AB2)+P(O1).P(O2)=
0.43^2+0.14^2+0.03^2+0.4^2=0.3654
