Answer:
13.1
Step-by-step explanation:
Add all the number together and divide by the number of students (aka total number of responses reported)
16+13+19+16+8+10+10=92
92/7= 13.1428 or about 13.1
Answer:
0.3
Step-by-step explanation:
(7.4-1.1) - (2.1-8.1)
Lets start with (7.4-1.1)
Step 1:
(7.4-1.1) =6.3 (All you do is subtract 7.4-1.1 and it gives you 6.3)
Step 2: Lets do (2.1-8.1)
(2.1-8.1)= -6 (2.1 minus 8.1 gives you -6 because 2.1 is smaller than 8.1 so it will give you a negative)
Step 3: Subtract
6.3-6
So your answer would be 0.3
Hope that helped :)
