Answer:
It is equal to 0.
Step-by-step explanation:
I can simplify it as follows:
sinα sin(90 - α) - cos(90 - α)(cosα)
Now sin(90 -α) = cosα and cos(90 - α) = sinα) ( for α < 90)
So the expression becomes:
sinαcosα - sinαcosα
= 0 .

0.8($8/book x 6 books) = $38.40
A) The probability the golfer got zero or one hole-in-one during a single game is between 10.01% and 11.38%.
B) The probability the golfer got exactly two holes-in-one during a single game is 8.57%.
C) The probability the golfer got six holes-in-one during a single game is close to 0%.
<h2 /><h2><u>How to determine probabilities</u></h2>
Since a miniature golf player sinks a hole-in-one about 12% of the time on any given hole and is going to play 8 games at 18 holes each, to determine A) what is the probability the golfer got zero or one hole -in-one during a single game, B) what is the probability the golfer got exactly two holes-in-one during a single game, and C) what is the probability the golfer got six holes-in-one during a single game , the following calculations must be performed:
- 1 - 0.12 = 0.88
- 0.88 ^ 17 = 0.1138
- 0.88 ^ 18 = 0.1001
Therefore, the probability the golfer got zero or one hole-in-one during a single game is between 10.01% and 11.38%.
- 0.88 ^ 18 - 0.12 ^ 2 = X
- 0.0857 = X
Therefore, the probability the golfer got exactly two holes-in-one during a single game is 8.57%.
- 0.12 ^ 6 x 0.88 ^ 12 = X
- 0.0000000001 = X
Therefore, the probability the golfer got six holes-in-one during a single game is close to 0%.

Answer:
Step-by-step explanation
S.P of a t.v = rs 7200
Loss % = 25%
Therefore, C.P = S.P (100/100-loss)
=7200(100/100-25)
=7200 x 100/75
=9600
So,now C.P = 9600
Profit% = 25%
Therefore, S.P = C.P (100+profit/100)
=9600(100+25/100)
=9600 x 125/100
=12000
So,the price he should sell to gain 25%
=12000
