A bag of marbles contains 4 red marbles, 5 green marbles, and 3
blue marboles. Karen pulls two
marbles out one after the other
without replacing the first marble,
what is the probability the first one
is red and the second is blue?

Will mark brainliest if provided fraction and right answer.

Probably 50% that she pulls out a red one because there are more red marbles than green and blue. And probably about 10-15% that she pulls out a blue because that is the least amount of marbles.

Step-by-step explanation:

554.4

step-by-step explanation:

44*12.6=544.4

  b.   the average rate of change of f(x) is less than the average rate of change of g(x).

step-by-step explanation:

since the length of the interval is the same in each case, we only need to compare the change in y-value to see which is greater.

so the change in y-value for function f is (6 )) = 9.

the table tells us

so the change in y-value for function g is (31 -1) = 30.

the change in y-value of f(x) on the interval is less than the change in y-value of g(x) on the same interval, so the average rate of change of f(x) is less than the average rate of change of g(x).
