Answer:
possible outcomes
Step-by-step explanation:
For any experiment, the sample space of this experiment is the set of all the possible results of the experiment.
In this case we have two spinners. The first has 5 colors, by spinning the spinner you can get up to 5 different results. Therefore the sample space is
For the second spinner there are 3 possible results. By spinning the spinner you can get the numbers 1, 2 or 3. Then .
Then, if the two spinners are rotated, the sample space would be:
possible outcomes.
The tree diagram shown in the attached image shows the 15 possible results
{R, 1} {R, 2} {R, 3} {O, 1} {O, 2} {O, 3} {Y, 1} {Y, 2} {Y, 3} {P, 1} {P, 2} {P, 3} {G, 1}
{G, 2} {G, 3}
Answer:
vertex = (- 1, 1 )
Step-by-step explanation:
Given a parabola in standard form
y = ax² + bx + c ( a ≠ 0 )
Then the x- coordinate of the vertex is
x = -
y = x² + 2x + 2 ← is in standard form
with a = 1 and b = 2 , then
x = - = - 1
substitute x = - 1 into the equation for y- coordinate of vertex
y = (- 1)² + 2(- 1) + 2 = 1 - 2 + 2 = 1
vertex = (- 1, 1 )
