Given that,
An oil company fills 1 over 10 of a tank in 1 over 5 hour.
To find,
How long it will take for the tank to fill completely.
Solution,
Let it takes t time to fill the tank completely. It can be calculated as follows :
Hence, the rate is "1 over 10 • 5 hours
". The correct option is (b).
Answer:
I hope this helps :D
Step-by-step explanation:

It can be done a lot easier: instead of calculating the probability of one head, two heads, three heads, ... one just needs to calculate the probability of no heads: that is simply 0.5
0.5
n
. If you subtract it from 1, you get the probability you want: it's because that's the chance of not no heads, meaning at least one head. So, the formula is: 1−0.5
1
−
0.5
n
More formally: if X is throwing at least one head,
()=1−(¬)
P
(
X
)
=
1
−
P
(
¬
X
)
, where ¬
¬
X
is throwing zero heads.
Answer:
you can use the quadratic formula to get theses:-
x =[-8 +/- sqrt(8^2 - 4*2*-3)] / 4
= -2 +/- sqrt88) / 4
= 0.35, -4.35 to nearest hundredth
