blue marble =1

green marble= 2

yellow marble = 3

red marble = 3

probability of picking a red marble without looking = 3/1+2+3+3

P(red marble)=3/9

P(red marble) =1/3

There are 9 marbles in total in the bag. Since there are 3 red marbles the probability of drawing out a red marble is 3/9 which can be simplified to 1/3

Find the equation of the line.<br> Through (-11, -1); perpendicular to y=15.
Harrizon [31]

Answer:

x = - 11

Step-by-step explanation:

y = 15 is a horizontal line parallel to the x- axis

a perpendicular line must therefore be a vertical line parallel to the y- axis with equation

x = c

where c is the value of the x- coordinates the line passes through.

the line passes through (- 11, - 1 ) with x- coordinate of - 11 , then

x = - 11 ← equation of perpendicular line
