So first add all of the marbles together: 3+2+6+9=20
Because there are 20 marbles together, that would be your denominator. 
All of the other numbers would be your numerator. So you would have:

3/20 green marbles
2/20 yellow marbles
6/20 blue marbles
9/20 red marbles

So your answer would be the probability of picking a red marble from the bag is 9/20 or 45%

Find the equation of the line described.
Lunna [17]

Answer:

y = -1/3x + 4

Step-by-step explanation:

y = 3x +5

current slope m is 3, perpendicular is opposite inverse which is -1/3

Passing through (6,2):

y = mx + b

2 = -1/3(6) + b

2 = -2 + b

b = 4

Use the perpendicular m = -1/3 and b = 4 to form equation of line:

y = mx + b

y = -1/3x + 4

What is the equation of a line (in slope-intercept form) with a slope of -1 and a y
crimeas [40]

Remember that the slope intercept formula is:

y = mx + b

m is the slope

b is the y-intercept

What we know:

slope: -1

y-intercept: 0.7

Therefore:

m = -1

b = 0.7

Plug the values of <em>m </em>and <em>b </em>in y = mx + b:

y = -1x + 0.7

OR

y = -x + 0.7

OR

y = 0.7 - x

^^^These are all written in slope intercept form but just in different ways

Hope this helped!
