247 is the correct answer!
% means out of 100 so If its 6% that = .06 then just multiply
Step-by-step explanation:

Angle C must = [180 - 73 - 57 ] = [180 - 130] = 50°
And using rhw Law if Sines, we have.....
AB/sin C = AC/sin B → 24/sin(50) = AC/sin(73) → AC = 24*sin(73)/sin(50) = about 29.96 in
The answer is B. Testing random samples of wild animals to decide whether they are healthy
If (55 + x)/2 is to be 67, then 55+x = 2*67, so x = 2*67 - 55 = 79
