Step-by-step explanation:

A.B = A × B

Dimension of the resultant matrix is (3 × 3)
Flip should get 4 boxes.
6*5=30
30/8=3.75
round up for 4.
By 30%
original=100%
100%+30%=130%
find 130% of 288846
1.30 times 288846=375499.8
answer is C which is closest
Mean= 9+8+14+12+5+14 divided by 6
which gives you 62 divided by 6
which is 10.33333
rounded to 2 decimal point = 10.33
median= 12 and 14
