Answer:
1648
Step-by-step explanation:
5/9 are girls. The 9 represents the total.
Set up a proportion and you have
5/9 = ?/3708
3708/9=412
412x5= 2060 girls
3708-2060= 1648
Answer:
590 would be your answer
Step-by-step explanation:
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
the square root of a number is: one number times itself equals that number. Confusing '-' An example is the square of 4 is 2 because 2 times 2 = 4, or the square root of 56 is 8 because 8 times 8 is 64. The square root of 175 is about 13.22875 because 13.22875 times 13.22875 = about 175
