First find the rate of growth
45000=18000(1+r)^(2010-2005)
Solve for r
r=((45,000÷18,000)^(1÷5)−1)×100
R=20%
Use it to find the population in 2015
P=45000(1+0.20)^(2015-2010)
P==111,974.4
The equation of the line is y = (1/2)x + 2
There are 714 boys in that school, you can cross multiply and divide to find the answer, if you wanna check. The way I wrote it was x (boys) / 1309 = 6/11.
x = 8
Since x = 8, you can plug in/substitute 8 for "x" in the equation:



2.82842
2.83 You answer is the 4th option
x = 9
Plug in 9 for "x" in the equation



4 Your answer is the 1st option
There are 6 sides on a dice. This means each number has a 1/6 chance of appearing. (1 number out of 6 sides). This includes 6, so the answer to a is 1/6. If you roll or do not roll a six, this means every side of the dice counts. The answer to be, by extension, is 6/6. Finally, c is b (the probability of anything) minus a (the probability of a six), representing every situation that is not a 6, so 5/6.
