Answer:
Ntoine and Tess have a disagreement over how to compute a 15% gratuity on $46.00.
This in real becomes :
dollars
But, Tess says, "It is easy to find 10% of 46 by moving the decimal point one place to the left to get $4.60. Do that twice. Then add the two amounts to get $4.60 + $4.60 = $9.20
So, Tess is wrong. Rather she should have done 10% of $46 giving $4.6 and then half of 4.6 that is 2.3 dollars. Getting a total of dollars which is the real amount.
P(A) = 1/4
p(B) = 2/3
p(A ∩ B) = 1/5
p(A).p(B) = 2/12 = 1/6 ≠p(A ∩ B )
thus no, they are dependent because P(A) ⋅ P(B) ≠ P(A ∩ B)
Since it is a right angle you would subtract 57 from 90 because both angles added together are 90°. 90-57= 33°
The answer is D. Hope it helps! :)
