Using the Pythagorean theorem:

a^2 + 24^2 = 26^2

a^2 + 576 = 676

a^2 = 676 - 576

a^2 = 100

a = SQRT(100)

a = 10

a jar contains 30 red, 40 blue, and 50 white buttons. you pick one button at random, find the probability that is not white
Jet001 [13]

Answer:

<em>The probability that the button is not white is </em><em>0.583</em>

Step-by-step explanation:

The jar contains 30 red, 40 blue, and 50 white buttons.

In total there are 120 buttons in the jar. So,

|\ S\ |=120

Let us assume that, A be the event of picking white buttons, so

|\ A\ |=50

So the probability of picking white button is,

P(A)=\dfrac{|\ A\ |}{|\ S\ |}=\dfrac{50}{120}

Then the event A^c will be not picking up white buttons, so the probability of not picking up white buttons is,

P(A^c)=1-P(A)=1-\dfrac{50}{120}=\dfrac{70}{120}=\dfrac{7}{12}=0.583

3x-6y=6 in function notation
JulijaS [17]
Subtract 3x from both sides:

-6y = -3x + 6

divide both sides by -6 to get y by itself:

y = 1/2x - 1

function notation is rewriting y as a function:

f(x) = 1/2x -1
