Answer:
the probability of having a widow peak and attached earlobe = 0.6667*0.66667 = 0.4445 = 44.5%
Step-by-step explanation:
Martha = widow's peak + attached earlobes.
Martha's dad = straight hairline + unattached earlobes.
Martha husband =straight hairline+ widow's peak + attached earlobes
what is the probability that Martha child will have a widow's peak + attached earlobes?
since,
Martha + Martha husband =straight hairline+ widow's peak + attached earlobes
the probability of the child having widow peak is 2/3 = 0.6667
the probability of the child having attached earlobes is 2/3 = 0.66667
the probability of having both = 0.6667*0.66667 = 0.4445
b is a answer
Step-by-step explanation:
formula
=a+b/2×h
Answer:
c) 10 units
The length of side RT of the polygon RT = 10
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given the coordinates of vertices R and T
R( -7 ,3) and T (3 ,3)
we have to find the length of side RT
We will use distance formula
RT = 
<u><em>Step(ii):-</em></u>
RT 
RT = √100
RT = 10
The length of side RT of the polygon RT = 10
