Answer:
Step-by-step explanation:
eq. of circle with (x1,y1 ) and (x2,y2) as extremities of diameter is
(x-x1)(x-x2)+(y-y1)(y-y2)=0
(x+3)(x-1)+(y-5)(y-9)=0
x²+3x-x-3+y²-5y-9y+45=0
x²+2x-3+y²-14y+45=0
x²+2x+y²-14y+42=0
x²+2x+1+y²-14y+49=-42+1+49
(x+1)²+(y-7)²=8
(x-(-1))²+(y-7)²=8

Answer:
9
Step-by-step explanation:
Expected number of defective is given as :
N x P = np
Where = number of the sample drawn from the production lot
P= percentage of bulbs In The lot which are defective
N = 15
P = 60% = 0.60
So when we do the multiplication,
We have:
NP = 15x0.60
= 9
So in conclusion the expected value of defective bulbs in the sample is 9.
