The measurement of a right angle is 61 What is the measurement of the missing angle.

stiv31 [10]

The answer is 29.

All angles in a triangle add up to 180. If its a right triangle, you know one of the angles is 90, and it gives you that one of the angles is 61. All you have to do is subtract to find what the last angle is.

180 - 90 - 61 = 29

Suppose two different methods are available for eye surgery. The probability that the eye has not recovered in a month is 0.002

antoniya [11.8K]

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)):

$P(A|R)=\frac{P(A) *P(R_A)}{P(A) *P(R_A)+P(B) *P(R_B)}\\P(A|R) = \frac{0.4*0.998}{0.4*0.998+0.6*0.995} \\P(A|R) = 0.40$
