The top 2 boxes, the first one because they are parallel which means lines that never meet or intersect, and the second box because it doesn’t have another line, which means it won’t intersect.
Answer:
V ≈3769.91
explanation:
V = π r 2h = π·10^2·12 ≈3769.91118 in³
Step-by-step explanation:
Mean of the origibal set = 20
No. of terms = 10
Sum = Mean x No. of terms
= 20 x 10 = 200
The sum of additional numbers to make the new set of observstion is 4 + 8 + 12...... + 40 = 220
New Sum = 200 + 220 = 420
The no of terms stay the same
New Mean = New Sum/ N
= 420/10
= 42
