Answer:
P(B) = 0.65
Step-by-step explanation:
We use the conditional probability formula to solve this question. It is
In which
P(B|A) is the probability of event B happening, given that A happened.
is the probability of both A and B happening.
P(A) is the probability of A happening.
In this question:
They are independent events, which means that . So
The answer is 14.3. You use the sin trig function because you are looking for the side opposite the angle and you are given the hypotenuse.
So, sin73=x/15, sin73*15=14.3
width of teacher's desk is 30 inches
Since the desks are similar then the ratios of corresponding sides are equal
let the width of teacher's desk be w, then
= ( cross- multiply )
30w = 900 ( divide both sides by 30 )
w = 30
