Answer:
The value of x is 11.
Step-by-step explanation:
The given number is 0.27272727..., and it is converted to the fraction as
..... (1)
Multiply both sides by 100.
.... (2)
Subtract equation (1) from equation (2),
Multiply both sides by x.
Divide both sides by 27.
Therefore the value of x is 11.
In general, the most probable distribution is in the ratio of the respective types, namely
Number of blue tails
=12*(53/(53+40))
=6.84
To check between 6 or 7, we use the hypergeometric distribution:
P(B=6)
=C(40,6)C(53,6)/(C(93,12)
=3838380*22957480/416579843773639
=0.211530
P(B=7)
=C(40,5)C(53,7)/(C(93,12)
=658008*154143080/416579843773639
=65563917120/269282381237
=0.243476
Hence the most probable number of blue tail fishes is 7
Note: it would be prudent to calculate P(B=8)=0.194443 to show that P(B=7) is indeed the highest value.
Answer:
The repetition is used to show how music was all she thought about.
Step-by-step explanation:
Answer:
(x-2)(x-2) or (x+2)(x+2)
Step-by-step explanation:
since you are squaring it, technically the terms are negative, but the product will be positive. when you multiply two negative factors, you get a positive answer. so either both can be negative or both can be positive.
