Answer:
Option A, C and D are correct.
Step-by-step explanation:
Option A is correct because if we take example of 
we get:
1,2,1
1,3,3,1
1,4,6,4,1
So we can see that either we read left to right or right to left we are getting same row
Option B is not correct because When we take power zero it will occupy first row hence, 
is not given by nth row.
Option C is correct because adding adjacent terms on a will give us the term directly below look at the example in option A.
Option D is correct because nth row will give coefficients in the expansion of (x + y) n-1 since, zero will occupy first row hence, nth row will be n-1.
There 12 out of 31women therefore it would be .39
Answer:
See attached graph
Step-by-step explanation:
The graph of distance from home as a function of time starts at the origin of coordinates (0,0) since at time zero minutes Varun is at home.
Then we represent his driving at constant speed (although it has not been specified in the problem) as a line with positive slope equal to his speed, that goes on for the first five minutes. After that, he reaches the traffic light that keeps him at the same distance from home for three minutes (notice the line representing the distance covered is flat from minute 5 to minute 8, while he is not moving).
Then he starts moving again (we assume at the same speed as before - so the line representing his position is again a line with positive slope and with the SAME inclination as that which represents the first 5 minutes of his trip.
The line ends at minute 15 which is the time it took him to get to work.
