Answer:14.200,14.204,14.210,14.240
Step-by-step explanation:
We will have a system of equations, and we are going to solve it by using substitution.
Let's make the equations.
x+y+z=2100
z+y=x
Since y and z are equal, I think it is easier for us to have them as one variable for now. Let the value of z and y be a.
These are the equations now.
x+2a=2100
2a=x
Since the second equation is giving the value of x, let it replace the value of x also in the first equation.
2a+2a=2100
4a=2100
2100÷4= 525
so, x and y equal 525. Let's put this in our original equation.
x+525+525=2100
x+ 1,050= 2,100
x= 1,050
So, x=1,050, y= 525 =z.
1) 50*50, our 2500
2) 1500
3)1500
4) 900
just multiply t the number of people by the amount each pays
Answer:
1/8, 0.0625
, or 6.25%
Step-by-step explanation:
50% of the cars are painted white.
1/2 * 1/2 = 1/4 * 1/4 = 1/8
Probability of A occuring 4 time(s) = 0.54 = 0.0625
Probability of A NOT occuring = (1 - 0.5)4 = 0.0625
Probability of A occuring = 1 - (1 - 0.5)4 = 0.9375
