Answer:
120
Step-by-step explanation:
The options are:
flake view, screened-in balcony, upgraded landscaping, pool - 5 in total
Using the fundamental counting principle formula - n! where n is the number of elements = 5, we have
n! =5! = 5x 4 x 3 x 2 x 1 = 120.
There are 120 120 options for purchasing a house in the community.
Answer:
50% chance for both
Step-by-step explanation:
If its two marbles then you have a 50% chance of picking up either the black or white. If four marbles are in the bag it would be 25%, if 10 then you have 10% and so on.
Answer:
999.1
Step-by-step explanation:
370.8 + 628.3
First task:
To determine this we need to make difference between system that doesn't have solution and system that has infinite number of solution. If when solving equations we get 0 = 0 that means system has infinite number of equations.
If we get 0 = some number that means that system doesn't have solution.
Multiplying first equation of second system by 2 and adding it to second equation we get 0=0 which means that this system has infinite number of solutions.
Answer is second system
Second task:
For this we need to set a system of equations and solve it. System looks like this:
x + y = 224
x*12 + y*8=2520
-------------------------
x represents older than 18 and "y" 18 and younger than that.
first equation we multiply with -12 and sum it with second.
-4y = -168
y=168/4 = 42
Answer is 42.
