Answer:
Mean Is 3 , Median Is 3
Step-by-step explanation:
The mean is the usual average, so I'll add and then divide:
0 + 1 + 2 + 3 + 4 + 5 + 6 = 21 divide by 7 you'll get 3
The median is the middle value, so first you'll have to rewrite the list in numerical order: There are seven numbers in the list, so the middle one will be the answer which is 3
0 , 1 , 2 , 3 , 4 , 5 , 6
Hello,
y=x²+2x+7
y=x+7
==>x²+2x+7=x+7
==>x²+x=0
==>x(x+1)=0
==>(x=0 and y=7) or (x=-1 and y=-1+7=6)
Sol={(0,7),(-1,6)}
