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
The equation of the vertical line that satisfies the condition is x=0.

Answer:
x=−1 or x=−9
Step-by-step explanation:
x2+11x+10=x+1
Step 1: Subtract x+1 from both sides.
x2+11x+10−(x+1)=x+1−(x+1)
x2+10x+9=0
Step 2: Factor left side of equation.
(x+1)(x+9)=0
Step 3: Set factors equal to 0.
x+1=0 or x+9=0
x=−1 or x=−9
