<u>2. </u><u>find</u><u> </u><u>cos Ф, sin Ф, tan Ф</u>
cos Ф = 5 / 13
Ф = 67.38
sin Ф = 12 / 13
Ф = 67.38
tan Ф = 12 / 5
Ф = 67.38
-----------------------
<u>3. find sin β, cos β, tan β</u>
sin <u>β</u> = 4 / 5
<u>β</u> = 53.13
cos <u>β</u> = 3 / 5
<u>β</u> = 53.13
tan <u>β</u> = 4 / 3
<u>β</u> = 53.13
It is expected that a number greater than 4 will be rolled 300 times
The sample space of a die is:
S = {1,2,3,4,5,6}
The probability of obtaining a number greater than 4 is:
In 900 rolls, the expected number of number greater than 4 is:
This gives
Hence, it is expected that a number greater than 4 will be rolled 300 times

Answer:
<em>The discount is 14.3%.</em>
Step-by-step explanation:
Regular price: $84
Discount: $12
We need to find what percent of $84 is $12.
To find what percent a part is of a whole, divide the part by the whole and multiply by 100.
12/84 * 100% = 14.2857...%
Answer: 14.3%
