Number one two and four are true
1. 3+5=8 and 8 is 80% of ten
2.the prob of drawing a red marble in the first go is 3/10 x 5/9 (for the probabilty of drawing a green one in the second go) =1/6
3. The probability OF drawing a blue marble is 20% (hence false)
4. 3+2 = 5, the same amount of red and blue marbles together as of green ones

In a parallelogram, the diagonals (the lines inside from corner to corner) bisect each other. That means the two halves of the diagonal are equal to each other.
So
-9-6x=x-30
-9-6x+6x=x-30+6x
-9=7x-30
21=7x
x=3
Okay, so a general rule for finding perpendicular lines in the form of y = mx + b is y = (-1/m) + b.
First, let's ignore b (-7) because we're going to find that later.
A perpendicular line to y = 4x + b is y = -1/4x + b.
Alright, so now let's plug in the values. They are in the form of (x,y), so let's plug them in accordingly.
3 = -1/4(4) + b
3 = -1 + b
b = 4
y = -1/4x + 4
So a line perpendicular to y = 4x - 7 is y = -1/4x + 4.
