Answer:
The lines a and b are parallel
Step-by-step explanation:
When we will translate line a, then the new line b will be formed.
Now, as translation preserves orientation each point on line a will be equidistant from line b , thus holding the condition and satisfying the property of two parallel lines.
Hence, line a and line b are parallel to each other.

Answer:
p(X> 6 ) = 0.01132 + 0.01672 = 0.0280
Step-by-step explanation:
The probability that the US woman would have more than six children is equal to the probability that she would have children that are equal to 7 or that she would that she would have children equal to 8 or more as shown on the table in the question
Now representing this mathematically we have
p(X > 6) = p(x =7 ) + p(x = 8 or more)
From the table the p(x = 7 ) 
And the p(x= 8 or more ) 
Hence p(X> 6 ) = 0.01132 + 0.01672 = 0.0280

Because there's one 3 & four 7's .

Because there are two 2's & four 9's
