Recall the double angle identity for cosine:
It follows that
Since 0° < 22° < 90°, we know that sin(22°) must be positive, so csc(22°) is also positive. Let x = 22°; then the closest answer would be C,
but the problem is that none of these claims are true; cot(32°) ≠ 4/3, cos(44°) ≠ 5/13, and csc(22°) ≠ √13/2...
Answer:
$6 per hour
Step-by-step explanation:
30 for 5 hours
$6 per hour
The data she would collect would be grouping people depending on how much video games they played.
This however, is not a statistical question. Instead, she should set for example: 1-3 hrs per week, 4-6 hrs, etc. People play different amounts of hours, and so you cannot set a specific number, it must be a "range-of-numbers".
Also the question itself is kinda judging and comparative
so overall, umm... this question isn't really good
hope this helps :D
Answer:
3 hours 26 minutes
Step-by-step explanation:
1/8 + 1/6 = 1/t where t is the required time in hours.
Multiply through by 24t:-
3t + 4t = 24
7t = 24
t = 3 3/7 hours
or 3 hours 26 minutes to the nearest minute.
If there were 5 yes votes for every 4 no votes, there were 5 yes votes for every 9 total votes, so 5/9 of the 7911 votes were yes. 5/9*7911=4395.
