If a spinner for a game is spun once, there is a 25% chance it will land on
bonufazy [111]

Answer:

Pr = 0.6

Step-by-step explanation:

Given

Let

O \to Orange

So:

P(O) = 25\% --- probability of O

n=2 --- Number of spin

Using the complement rule, the probability that a spin will not land on orange is:

P(O') = 1 - P(O)

P(O') = 1 - 25\%

Express as decimal

P(O') = 1 - 0.25

P(O') = 0.75

On two spins, the probability that it will not land on orange is:

Pr = P(O') * P(O')

So, we have:

Pr = 0.75* 0.75

Pr = 0.5625

<em></em>Pr = 0.6<em> --- approximated</em>

Write the equation of the line, in point-slope form. Identify the point (-2, -2) as (x1, y1). Use the box provided or the upload
zimovet [89]

Answer:

  • m = (2-(-2))/(2-(-2)) = 4/4 = 1
  • y +2 = 1(x +2)

Step-by-step explanation:

The point-slope form of the equation for a line with slope m through point (x1, y1) is ...

  y -y1 = m(x -x1)

To find the slope of the line, find the ratio of the difference in y-values of the points to the difference in corresponding x-values. Here, the slope is ...

  m = (2 -(-2))/(2 -(-2)) = 4/4 = 1 . . . work to compute slope

The problem statement tells you x1 = -2, y1 = -2. Putting the numbers in to the point-slope form gives ...

  y -(-2) = 1(x -(-2))

  y + 2 = x + 2 . . . equation form with m, (x1, y1) filled in

__

The answer at the top leaves the slope shown as 1. We don't know how much simplification you are expected to do. Obviously, this <em>could</em> be simplified to y=x, but then the use of (-2, -2) for the point would not be obvious.
