Answer:
A. Five behind the line.
Step-by-step explanation:
We can use a number line (see below) to solve this problem.
Start at 0.
Jump eight units to the right.
Then jump in succession six, four, and nine units to the left.
Finally, jump six units to the right.
You end up five units to the left of zero (five squares behind the line).
Mathematically,
0 + 8 - 6 – 4 - 9 + 6 = -5

Answer:
Mortality rate is 0.5 per 1000 habitant
the number of deaths have increased (from 210 to 250)
Step-by-step explanation:
Hello
Mortality rate is the number of deaths in a specific population,usually expressed in units of deaths per 1,000 individuals per year
where
S=Mortality rate
D=deaths
P= population
n= is a conversion form ,such as multiplying by 10^{3}=1000, to get mortality rate per 1,000 individuals( we will use n=3)
step 1
asign
S=unknown
D=250
P=500000
n=3, (for each 1000 people)
step 2
Replace
Mortality rate is 0.5 per 1000 habitant
step 3
what if S=0.42
S=0.42(assuming it is 0.42 per 1000,n=3)
D=unknown
P=500000
the number of deaths have increased (from 210 to 250)
Have a great day
