Karen has a bag containing the following marbles: 3 red marbles
4 green marbles
1 yellow marble
What is the probability of randomly selecting a
green marble or a red marble from the bag?
A. 2/3
B. 7/8
C. 3/8
D 4/5

its B because 4+3=7 and 3+4+1=8

Step-by-step explanation:

because 4+3=7 and 3+4+1=8 so it is 7/8

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
