A jar contains 3 red marbles, 2 orange marbles, 3 green marbles and 4 blue marbles. One marble is chosen at random

Red: 1/4

Orange: 1/6

Green: 1/4

Blue: 1/3

Step-by-step explanation:

3 red marbles + 2 orange marbles + 3 green marbles + 4 blue marbles = 12 total marbles

3 red marbles / 12 total marbles = 3/12 = 1/4

2 orange marbles / 12 total marbles = 2/12 = 1/6

3 green marbles / 12 total marbles = 3/12 = 1/4

4 blue marbles / 12 total marbles = 4/12 = 1/3

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.

= 5

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5
