Point B is in the interior of ∠AOC, m∠AOC = 108°, m∠AOB = 3m∠BOC. Find m∠AOB.
valentinak56 [21]
If point is the interior of <AOC ,
 then m<AOB + m<BOC = m< AOC    (  angle addition postulate )         eq 1
          (3m<BOC )  +   m <BOC  = m <AOC   {   m<AOB =  3m<BOC)
              4m <BOC  =    108  
                   m<BOC  =    27 

      m<AOB + m <BOC =  m < AOC 
       m<AOB  =   108 - 27 
        m <AOB  =    81

Paul [167]

Answer:

Step-by-step explanation:

Given that the  mean incubation time for a type of fertilized egg kept at a certain temperature is 25 days.

Let X be the incubation time for a type of fertilized egg kept at a certain temperature is 25 days.

X is N(25, 1)

a) Normal curve is in the attached file

b) the probability that a randomly selected fertilized egg hatches in less than 23 days

=P(X

we convert x into Z score and use std normal distn table to find probability

P(X

i.e. we can say only 2.5% proportion will hatch in less than 23 days.
