Step-by-step explanation:
The total number of student can be solve by dividing the
partial student by its percentage of the overall student. Since there are 180
students in the band and it represnts 9% of the total students of the scool. So
the number of studetns are 180/0.09 = 2000 students
In triangle b. we know that tan(x) = Opposite side to x angle / Adjacent side to angle x.
By substituting in above formula,
tan(x) = 12/5 = 2.4
x = tan^-1(2.4) = 68 degrees.
And in triangle a. i am not clear with the angle. Is it 51 or any other?
The fourth event is dependent. Not replacing draws changes the probability of drawing a certain number or thing.
