Answer:
1) 5 2) 6 3) 1.25 or -1.75
Step-by-step explanation:
1. x^2 - 25 = 0
x^2 - 25 = 0
First, add 25 to both sides!
x^2 = 25
Now square root both sides.
x = 5
2. (x-2)^2 = 16
First, square root both sides.
(x-2) = 4
Add 2 on both sides.
(x) = 6
x = 6
3. Quadratic Formula = -b ± / 2a
Substitute in:
-6 ± / 2(2)
-6± / 4
Both forms:
-6 + / 4
5 / 4 = 1.25
Negative:
-6 - 1 / 4
-7 / 4 = -1.75
Answer:
-11/4

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}
