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
6 + 2 < 9 + 3...u r correct
Answer:
I think it would be 50 Meters. Please correct me if I'm wrong.

Answer:
( 1, -6 )
Step-by-step explanation:
The solution to the graph is ( 1, -6 ) as that is the point where both equations cross. To double check you can also fill in the equations with the points given and they both should solve.
Answer:
Actual distance = 24 km
Step-by-step explanation:
16 cm
2cm = 3 km
We could use a ratio to do this
16/2 = x/3
8=x/3
Multiply both sides by 3
24=x
Hope this helps :)
