<u>Answer:</u>
The correct answer option is 
.
<u>Step-by-step explanation:</u>
We are to find the probability that both your parents were born on weekend (either Saturday or Sunday).
Total number of days in a week = 
Number of days in weekend = 
Probability of being born on weekend = 
P (both parents were born on weekend) = 
= 4/49
8.5 as a fraction is 8.5/1. To make the denominator 4, you must multiply both the top and bottom by 4 (4x8.5/1x4). This gives you your answer, which is 34/4. To double check this, you just divided 34 by 4. This equals 8.5, which is the original number.
66 rounded to the nearest hundred is 100.
If the last two digit of the number are 50 or above round up.
But....
If the last two digit of the number are 49 or below round down.
But remember also.....
If the last two digit are zeros, do not round, it is already in the hundred.
Hope this helps u.
Reflection about the y-axis is according to the rule
(x,y)->(-x,y)
Therefore F(x,y) -> F'(-x,y)
The distance between F' and F is (-x,y)-(x,y)=-2x, or the positive distance is 2x.
