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.

Answer:
2.4
Step-by-step explanation:
Given :
Mean :
![$=-0.0375 \left[ \frac{t^4}{4} \right]^4_0 + 0.225 \left[ \frac{t^3}{3} \right]^4_0$](https://tex.z-dn.net/?f=%24%3D-0.0375%20%5Cleft%5B%20%5Cfrac%7Bt%5E4%7D%7B4%7D%20%5Cright%5D%5E4_0%20%2B%200.225%20%5Cleft%5B%20%5Cfrac%7Bt%5E3%7D%7B3%7D%20%5Cright%5D%5E4_0%24)
= 2.4
Therefore, the mean is 2.4
