71.4 and to check just multiply 71.4 times 5 and it'll get 357
0.2 is rounded to the nearest tenth
That 1,2,3,4,5,6 is one the die and it has a chance to at least get all the numbers at least once but u dont have enough data so i can help u more.
If you estimated 3.7 to 4 and 5.1 to 5 the answer would be 20. You would have 20 and now you can think is 20 a reasonable answer for 3.7x5.1. The answer for 3.7x5.1=18.87, so the answer is yes.
Hope that helped:)
