Answer:
Step-by-step explanation:
Here X no of defective batteries is binomial with p = 1% = 0.01
q = 1-p=0.99
(Because each battery is independent and there are only two outcomes)
Prob that shipment is accepted is for n =36, 
=P(x=0,1,2)
= 
= 0.9944
Answer:
1,rational
2,irrational
3,rational
4,rational
5,irational
Step-by-step explanation:
for number 1 and 2just ask your self what times what =this and
number 4 just divide 72 by 4 and
number 5 pie is always irrational
In the x quarts of 2% fat milk, there is 0.02x quarts of fat.
in the y quarts of 4% fat milk there is 0.04y quarts of fat.
together, there is (x+y) quarts of milk, and 0.24 quarts of fat.
the equations are:
x+y=9
0.02x+0.04y=0.24
multiply the first equation with 0.02: 0.02x+0.02y=0.18
subtract this new equation from equaition 2 to eliminate x:
0.04y-0.02y=0.24-0.18
0.02y=0.06
y=3
x=9-3=6
x is twice as much as y.
He used twice as much as the 2% fat milk than the 4% fat milk.
so the first choice is the correct answer.
The answer is 12. theorem- in the above figure if bf is a perpendicular to ca then cf and fa are congruent
