Answer: 0.0325
Step-by-step explanation:
Binomial probability distribution formula for x successes in n trials:-
, where n is the number of trials , p is the probability of success.
Given : The probability that taxpayers who filed their tax return are electronically self-prepared their taxes : 
If three tax returns submitted electronically are randomly selected, then the probability that all three were self-prepared is given by :-
Hence, the probability that all three were self-prepared =0.0325
0.423288/0.423 US ton,
divide the mass value by 907.
The value of ∠BAC in the isosceles triangle is 9.7°
<h3>
Cosine rule</h3>
Cosine rule is used to show the relationship between the sides and angles of a triangle. It is given by:
a² = b² + c² - 2bc*cos(A)
where a, b, c are the sides of the triangle and A, B, C are the angles opposite the sides.
AB = AC = 1185 (isosceles), BC = 200, let ∠BAC = x°, hence:
200² = 1185² + 1185² - 2(1185)(1185)cos(x)
2(1185)(1185)cos(x) = 2808450
cos(x) = 0.9857
x = 9.7°
The value of ∠BAC in the isosceles triangle is 9.7°
