Answer:
8
Step-by-step explanation:
mean of A=28+23+30+25+27/5 = 26.6
average of B=22+19+15+17+20/5 = 18.6
now,
difference= 26.6-18.6
=8,,
Answer:
The current population (in 2005) is 4000 because it is the constant. The slope tells us how many people are added to the population, so 70 per year. For ex. 2008 (2008- 2005 = 3=> 3 x 70 = 210 => 210 + 4000 = 4210).
