Step-by-step explanation:
Answer for the before math question asked by you.
+56×-16 = -240
When +multiplied by - the answer will be in -. 56×16 is 240 so it is -240.
12×-11×4 = -158
The same process of above and get the answer as -158.
-3×-6= 18
-2×-1 = 2
When - multiplied by - it is +.
When + multiplied by + it is +
3×6=18,2×1=2.
18×2=36
+36
Same above formula +25
Formula of first question -32
Answer:
mode = 14, median is 14 and mean is 13
in 1 litre petrol car runs 20km
in 9/5 litre petrol car runs= 20× 9/5
= 36km
2) mode is the most repeated term which is 14 in this case.
to find median we first need to write it in increasing order
2,10,12,14,14,14,14,14,15,16,18
median is the middle term i.e 14
mean = sum of all observation/ total observation
= (2+10+12+14+14+14+14+14+15+16+18)/11
= 143/11
= 13
