Sin = opposite/hypotenuse
so sin (x) = 12/13
answer is 12/13
It shows you what to do first (don't quote me o. this only use this if you can't find any other answer)
The ratio of false positives to false negatives is (d) 3.5
<h3>How to determine the ratio?</h3>
The table of values is given as
Activates. Does not activate Row Totals
Lightning in area 88% 2% 90%
No lightning in area 7% 3% 10%
Column Totals 95% 5% 100%
The false negative is when there is lighting and it does not activate
So, we have
False negative = 2%
The false positive is when there is no lighting and it activates
So, we have
False positive = 7%
When represented as ratio, we have
Ratio = 7% : 2%
So, we have
Ratio = 7 : 2
This gives
Ratio = 7/2
Evaluate
Ratio = 3.5
Hence, the ratio is (d) 3.5
