The population of a city in 2005 was 18,000. By 2010, the city's population had grown to 32,800. If the population growth follow

kotykmax [81]

Answer:

The projected population for 2015 is around 83,600 people.

Step-by-step explanation:

If between 2005 and 2010, the population grew by 32,800 people, and the model of this problem is linear. Then that means in another 5 years, another 32,800 people would populate the area. Hopefully this makes sense!

Suppose that a nonnegative integer solution to the equation u + v + w + x + y = 12, thought of as a 5-tuple (u,v,w,x,y) is chose

son4ous [18]

Answer:0.2

Step-by-step explanation:

Given

$u+v+w+x+y=12$

total solution for $u+v+w+x+y =12$ is given by $^{n+r-1}C_{r-1}$

here $n=12\ r=5$

i.e. $^{12+5-1}C_{5-1}=^{16}C_4$

For $u=1$

$1+v+w+x+y=12$

$v+w+x+y=11$

no of solutions for this equation is

$^{11+4-1}C_{4-1}=^{14}C_3$

if one solution is chosen at random Probability that u=1

$=\frac{^{14}C_3}{^{16}C_4}$

$=\frac{364}{1820}=0.2$
