Answer:

13/25

Step-by-step explanation:

Firstly, we add the total number of persons together

That would be 20 + 6 + 17 + 7 = 50

The number of persons with brown eyes = 20

The number of persons with green eyes = 6

Probability of selecting someone with brown eyes = 20/50

Probability of selecting someone with green eyes = 6/50

The probability of selecting someone with brown or green eyes = Probability of selecting someone with brown eyes + Probability of selecting someone with green eyes = 20/50 + 6/50 = 26/50 = 13/25

Hey there!☺

Answer:\boxed{y=\frac{-1}{2}}

Explanation:

\frac{y}{-8}=\frac{1}{16}

In our first step, we will use the cross multiply method:

\frac{y}{-8}=\frac{1}{16}\\  y*(16)=(1)*(-8)\\16y=-8

In our second/last step, we will divide both sides by 16:

\frac{16y}{16}=\frac{-8}{16}\\y=\frac{-1}{2}

Hope this helps!☺

The first step for solving this is to write the expression on the right side of the equation in exponential form.
5^{x-3} =  5^{-2}
Since the bases are the same,, set the exponents equal to each other.
x - 3 = -2 
Now move the constant to the right side and then change its sign.
x = -2 + 3
Now calculate the sum to get your final answer.
x = 1
This means that the correct answer to your equation is going to be x = 1.
Let me know if you have any further questions.
