PLEASE ANSWER THE QUESTION<br> 1/3 x + y = 4<br> SOLVE FOR Y( THIS MEANS GET THE Y BY ITSELF.)

Marrrta [24]

Subtract 1/3x from the left side of the equation and subtract it from the right side of the equation. So it would be y = 4 - 1/3x

Probability =

   (number of ways it can come out the way you want it to)
divided by
   (total number of ways it can come out).

Total number of ways it can come out =

      number of bottles in the cooler

   = (10 + 15 + 13) = 38 .

Number of ways it can come out the way you want it to =

   (soda + lemonade)

      = (10 + 15) = 25 .

Probability of coming out the way you want it to =

   25 / 38 = about 65.8 % .

The decreasing population, p, of owls in a national park is being monitored by ecologists and is modeled by the equation p=−0.

n200080 [17]

By solving a quadratic equation, it can be verified that

The owl population will disappear after 329.12 years

What is a quadratic equation?

At first it is important to know about equation

Equation shows the equality between two algebraic expressions by connecting the two algebraic expressions by an equal to sign.

A two degree equation is known as quadratic equation.

Here, a quadratic equation needs to be solved

The decreasing population, p, of owls in a national park is being monitored by ecologists and is modeled by the equation p= $-0. 4t^2+128t+1,200$

For population to disappear, p =0

$-0. 4t^2+128t+1,200 = 0\\0.4t^2 -128t - 1200 = 0\\4t^2 - 1280t - 12000 = 0\\4(t^2 - 320 t - 3000) = 0\\t^2 - 320t -3000 = 0\\t = \frac{-(-320)\pm \sqrt{(-320)^2 - 4 \times 1 \times (-3000)}}{2 \times 1}\\t = \frac{320 \pm 338.23}{2}\\t = \frac{320 + 338.23}{2} \ or \ t = \frac{320 - 338.23}{2}\\t = 329.115 \ or \ t = -9.115$

But t = -9.115 is not possible as time cannot be negative

So, the owl population will disappear after 329.12 years
