The answers C because it is below sea level and sea level is 0 so it has to be negative
Answer: 233 people per thousand
Step-by-step explanation:
Using extrapolation method,
if 150/k in 1950,
200/k in 1990,
275/k in 2020,
2003 lies in between 1990 and 2020. So, you extrapolate the values of 200/k and 275/k for the years respectively.
Therefore,
(2003 - 1990)/(2020 - 2003) = (x - 200)/(275 - x)
Where x is the number of retirees per thousand for 2003
Making x the subject of relation in the above equation.
Cross multiply the equation above;
(2003 - 1990)(275-x) = (2020 - 2003)(x - 200)
13(275 - x) = 17(x-200)
3575 - 13x = 17x - 3400
Collect the like terms
3575+3400 = 17x + 13x
30x = 6975
x = 6975/30
x = 232.5
x = 233 people per thousand to the nearest integer
Answer:
0.75
Step-by-step explanation:
Since we use the base 10 decimal system, first convert 3/4 to out of 100:
3/4 = 75/100
We divide 75 by 100 to get 0.75
5179-8579 is the answer and you'll see why, the ration is the difference between two numbers and in which you would call the following number on the right, shown as 8579
