Answer :
0.53
Step-by-step explanation:
Given the following :
Probability of female = probability of success on a single trial = 0.51
Number of babies = 80
Probability that more than half of the babies are female : p(X >80/2) = P(X > 40)
The problem can be solved using the binomial probability function :
P(X > 40) = [ p(X= 41) + p(X= 42) +.... +p(X= 80)]
In other to save computation time, we can use the binomial probability calculator
Hence ; P(X > 40) = 0.527 = 0.53
Answer:
The coefficient is 
Step-by-step explanation:
The given sum is

We can choose to add only the coeffients of
or simplify the whole sum.

We collect the LCM for the
terms;

This will give us;

Which is the same as

The coefficient is

Answer:
It is the secon option ∆TRS ≈ ∆TPQ ; SAS
Step-by-step explanation: angle t is equal to angle t because it is the same angle
line TR divided by line TP is equal to line TS divided by TQ
(3+3i) - (13+15i)
=3+3i-13-15i
=-10-12i
