Answer:
2/15
Step-by-step explanation:
2 green pens, 3 blue pens, 4 red pens, and 1 black pen =10 pens
P(red) = red/total = 4/10 = 2/5
Keep the pen
2 green pens, 3 blue pens, 3 red pens, and 1 black pen =9 pens
P(red) = red/total = 3/9 = 1/3
P(red,red) = 2/5 * 1/3 = 2/15

Answer:
oh hey I gotchu-
first of all you are gonna make that into two rectangle by slicing the top off if that makes sense so you now have a large rectangle (11×12) and a small one (3×8) now you use the area formula for rectangles base×height so the small one becomes (3×8)=24 and the large one is (11×12)=132. now to make them into one shape for the total area you add those two values 132+24=156 so your total area is 156m²
Answer: 50%
Step 1 add 18+20 = 38
Step 2 add 10+9= 19
Step 3 divide 19 by 38 = 2
So if would be half which is equal to 50%
Answer:
are zeroes of given quadratic equation.
Step-by-step explanation:
We have been a quadratic equation:
We need to find the zeroes of quadratic equation
We have a formula to find zeroes of a quadratic equation:
General form of quadratic equation is 
On comparing general equation with b given equation we get
a=2,b=-10,c=-3
On substituting the values in formula we get
Now substituting D in 
we get
Therefore,
