Answer: 
Step-by-step explanation:
Here, According to the question, The population of the world is 4 billion (approx).
Again According to the question, The world's population has grown at an average rate of 1.9 percent per year since 1945.
Therefore, after 1975 the growth rate will remains same.
Thus, the population of the world after t years,
(By the formula 
)
⇒
Where 1.019 is the growth rate and 4 billion is the initial population.
Answer:
Worked 40 hrs in week
Pay $300 for week
Step-by-step explanation:
Hours: 7-11a.m = 4
12-4p.m = 4 So, 4+4=8 hrs per day
So, 8 hrs per day × 5 days a week (8×5)=40
Worked 40 hrs in week
Pay: $7.50/hr So, $7.50×40 hrs (7.50×40)=300
So, $300 pay for week

Your classmate's error about AB and DC being complimentary and parallel is that they misapplied the alternate angle property.
<h3>Why are AB and DC not parallel?</h3><h3 />
There isn't enough evidence presented in the diagram to say that AB and DC are parallel.
The evidence required would be proof that angle AWZ is equal to angle WZY.
Instead, all we have is that angle AWZ and angle XYC are equal which does not tell us what we need to know about AB and DC being parallel.
