You randomly draw a marble from a bag of marbles that contains 8 blue marbles, 5 green marbles, and 8 red marbles. What is P(draw a blue or red marble)?

Step-by-step explanation:

Probability = Number of favorable outcomes / Number of possible outcomes

There are favorable outcomes (the marables that are either blue or red).

There are possible outcomes (the total marables).

P (draw a blue or red marable) ≈

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
