Answer:
Associative Property of Multiplication
Step-by-step explanation:
We are given the following information in the question:
It is said by Lily that
This is correct statement to say.
This is the commutative property of multiplication.
- The commutative property says that the order in which we multiply numbers does not change the product of the two numbers.
Associative property of multiplication
- The associative property states that we can multiply any two numbers however they may be grouped.
- Multiplying by changing the order of the numbers would not change the product of the numbers
The order of multiplication of number does not effect the final product. We may cho0se any order.

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
