A box contains 11 marbles—7 red and 4 green. Five of these marbles are removed
at random. If the probability of drawing a
green marble is now 0.5, how many red
marbles were removed from the box?
A. 1
I
B. 2
C. 3
D. 4
E. 5

is there supposed to be a diagram or a graph for this one? ?

step-by-step explanation:

cool stunts are flippin i think

sitting on a chair

and using stick feet

the area of a triangle is determined by the formula: base x height * 1/2

you'll need to assign a base to the triangle. based on the vertices given, the simplest base would be the line segment from (-2,1) to (2,1). the distance between any two numbers is found by just subtracting them. here, you should subtract the x values to find the distance of this side.

2 - (-2) = 4.

so the distance (aka the length of the base) is 4. the height of the triangle is the distance between the base and the highest point on the triangle which is (3,4). we should subtract the y values this time to find the height/distance.

4 - 1 = 3

so the height is 3.

base = 4

height = 3

hope this if needed hmu
