Answer:
d) 0.4
Step-by-step explanation:
P(Ra) = 0.998
P(Rb) = 0.995
P(A) = 0.4
P(B) = 0.6
The probability that method A was performed, given that the eye was recovered within a month of the surgery, is determined by the probability that the eye recovered within a month with method A (P(A) x P(Ra)),divided by the probability that the eye recovered within a month with either method (P(A) x P(Ra) + P(B) x P(Rb)):
The probability that method A was performed is 0.40.
S = s(s +2h) = 24(24 +2*20) = 1536 . . . . square inches
Selection C is appropriate.
Music fractions are kinda like math.
In 4/4 time a quarter note (indicated by the denominator of 4) gets one beat
In 6/4, the numerator indicates 6 beats per bar
In the unusual 4/8 time, the denominator of 8 indicates an eighth note gets one beat
