Answer:

Step-by-step explanation:
Probability is found by dividing the number of favorable outcomes by the total number of outcomes.

For this problem, the favorable outcome is selecting a blue or green marble. There are 8 outcomes for this because there are 6 outcomes for blue and 2 fr green.
The total outcomes are all the marbles. Each marble could be an outcome, so there are 13 outcomes (1 for each marble).

This fraction cannot be reduced, so the probability of selecting a blue or green marble is <u>8/13.</u>
Answer:
When there are numbers like that next to the radical it means multiply. like this: 2<u>√9</u>. You would first figure out the square root. <u>Square root of 9</u> is 3. 2 times 3 is 6.
After you figure out those problems, you just need to put the number, x, and y in an equation with 2 unknowns.
Step-by-step explanation:
The equation for the line of reflection is x = 2.
If you drew a vertical line crossing the x-axis on x = 2, the drawing will be the same on the left and right side, as if one side was drawn then exactly copied on the other side but flipped.
The figure is symmetrical, and x = 2 is the line of symmetry.
Hope this helps!
You have to put the numbers in order and find the middle value so in this case it's-
2, 4, 4, 5, 6, 7, 8, 8, 8
The answer is $6
