Answer:
12 per 1,000 / year would be population growth
Step-by-step explanation:
To know the population growth it is important to know what it contributes to its growth and that it decreases it.
Birth rate ==> increases growth
Death rate ==> decreases growth
Immigration rate ==> increases growth
Emigration rate ==> decreases growth
Now it only remains to add those that increase growth and subtract those that decrease, like this:
14 per 1,000 / year - 6 per 1,000 / year + 5 per 1,000 / year - 1 per 1,000 / year = 12 per 1,000 / year
12 per 1,000 / year would be population growth
Answer: The required system of equations representing the given situation is

Step-by-step explanation: Given that Sam needs to make a long-distance call from a pay phone.
We are to write a system to represent the situation.
Let x represent the number of minutes Sam talked on the phone and y represents the total amount that he paid for the call.
According to the given information,
with prepaid phone card, Sam will be charged $1.00 to connect and $0.50 per minute.
So, the equation representing this situation is

Also, if Sam places a collect call with the operator he will be charged $3.00 to connect and $0.25 per minute.
So, the equation representing this situation is

Thus, the required system of equations representing the given situation is

Answer: (A) randomly selected elements within each of the strata form the sample.
Step-by-step explanation:
Stratified random sampling is a random sampling technique in statistics .
- It includes the partition of the entire population into sub-parts called strata.
- The strata are formed on the basis of the characteristics shared by members .
- After the formation of strata, researcher randomly selects participants from each strata to ensure that that the participant of every group must involve in the sample to represent each character.
Hence, the correct answer is :
(A) randomly selected elements within each of the strata form the sample.
