For part A. 0.85
For part b. 11.9
Explain
Cost of each track in album A= total cost downloading album a/ total number of track
The problem give us a has 11 trackers and the total cost of download is 9.35 pounds
9.35/11
= 0.85
Now we are given each track cost in album b cost the same as track on A
Cost of each track in album B is 0.85
Now we are given if Jane download album B , B will be 14 tracks
Total cost of downloading is album B= number of tracks in album Bx cost of each track in album B
14x0.85 pound
= 11.9
When radicals (square roots) include variables, they are still simplified the same way. We just have to work with variables as well as numbers
1) Factor the radicand (the numbers/variables inside the square root). Factor the number into its prime factors and expand the variable(s).
2) Bring any factor listed twice in the radicand to the outside
Answer:
P( top two horses are predicted incorrectly in incorrect order)
= 
Step-by-step explanation:
In the horse race the outcome can be predicted in 5! = 120 ways.
Now suppose the top two horses were predicted incorrectly in incorrect order. Now, the top horse can be predicted incorrectly in 4 ways.
Suppose the top horse was predicted to be in k-th position where k = 2, 3 ,4,5
so the second horse can be predicted to be in place from 1 to (k - 1)
So, the top two horses can be predicted incorrectly in incorrect order
in 
= 10 ways
and for each prediction of the two the remaining horses may be predicted in 3! = 6 ways.
Hence ,
P( top two horses are predicted incorrectly in incorrect order)
= 
=
Answer:
False
Step-by-step explanation:
False. The period of y = tan x is π, whereas that of y = cos x is 2π.
