Answer:
The population growth rate is of 1.86%.
Step-by-step explanation:
Population growth rate:
Immigration plus births subtracted by emigration and deaths.
In this question, we have that:
Birth: 14.3 per 1000
Death: 11.8 per 1000
Immigrations: 21.6 per 1000
Emigrations: 5.5 per 1000
Rate:
As a percentage:
Multiply by 100%. So
0.0186*100% = 1.86%
The population growth rate is of 1.86%.
Answer: n ≥ 4
Step-by-step explanation: To solve for <em>x</em> in this inequality, your goal is the same as it would be if you were solving an equation which is to get <em>x</em> by itself on one side of the inequality.
Since 3 is being subtracted from 2n, add 3 to both sides of the inequality to get 2n ≥ 8. Now since <em>n</em> is being multiplied by 2, we need to divide by 2 on both sides of the inequality to get <em>n ≥ 4</em>.
Our next task is to graph <em>n ≥ 4 </em>on a number line and to do that, we start with a closed dot at 4. The reason we use a closed dot at 4 is because not only is <em>n</em> greater than 4 but it's also equal to 4. Next we draw an arrow going to the right on our number line to represent all numbers greater than 4.
When graphed, it should look something like the image attached.
