The building is 38 x 2 = 76 feet tall.
What do you mean doubling? You can add 7+7+7 which equals 21.
Answer:
B. 1/2
Step-by-step explanation:
divide/
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
