50.7 x 8 = 405.6
Hope this helps
All u have to do is subtract both of the temps and then u will have to answer
Cos 210° = cos ( 180° + 30° ) - cos 30° = - √3/2
Consider this:
If a test gives a positive result for an infected person 98% of the time, that means that 2% of the time, it gives a negative result for an infected person, which would be a false negative.
Then,
if the test is 97& accurate (not precise) for non-infected people, that means that it gives a negative result 97& of the time. So a positive result will be given 3% of the time for non-infected people, which is considered a false positive.
It's m. All you have to do is distribute
