Answer:
Step-by-step explanation:
1) Tangent makes 90 degrees with the radius. Hence
a) Angle ABD = 90-angle BDC = 90-61.3 = 28.7
b) Triangle BCD is isosceles since tangents have equal length.
Hence angle BCD = 180-(61.3+61.3) = 57.4
c) Angle BDC = 57.4 (since triangle BCD is isosceles)
d) Angle BAC and Angle BCD are supplementary. Hence angle BAC = 122,6
-------------------------------------------
2) Arc length of minor arc BC = 
b) ARc length of minor arc = circumference -minor arc
= 18.713
---------------------------------------------
3) circumference = pi d =
Answer:
0.0467
Step-by-step explanation:
Probabilty of being defective is 
So probability of being good is 
Now,
Probability that all 3 of them are good is:

Now, to find probability of rejection, we subtract the now found probability from 1. Thus, we have:
1 - 0.9533 = 0.0467
