Using the combination formula, it is found that there are 17,157,323,000,000,000 color combinations of 15 beans have at least 6 green beans.
The order in which the beans are chosen is not important, hence, the combination formula is used to solve this question.
Combination formula:
Th total number of combinations of 15 beans from a set of 30 + 30 + 30 = 90 is:
With less than 6 green, we have:
0 green:
1 green:
2 green:
3 green:
4 green:
5 green:
Hence, the total for the number of combinations with less than 5 green is:
Subtracting the total amount of combinations from the number with less than 5 green, the number of combinations with at least 6 green is:
There are 17,157,323,000,000,000 color combinations of 15 beans have at least 6 green beans.

Step-by-step explanation:
Number of red beans = 30
Number of Blue beans = 30
Number of green beans = 30
How many color combinations of 15 beans have at least 6 green beans?
Since at least 6 of the beans must be green,
Then (15 - 6) = 9
Then, the remaining 9 could be either red, blue or green.
Therefore, C(9 + (9 - 1), 3)
C(17, 3) = 17C3
nCr = n! ÷ (n-r)! r!
17C3 = 17! ÷ (17 - 3)! 3!
17C3 = 17! ÷ 14!3!
17C3 = (17 * 16 * 15) / (3 * 2)
17C3 = 4080 / 6
17C3 = 680 ways

Slope for g(x)
y = mx + b
y = 5x + 1
m = 5
The slope for f(x) is twice the slope of g(x).
B. f(x)'s y-intercept is -1 because y = -1 when x = 0. g(x)'s y-intercept is 1 because 1 is in the "b" spot in y = mx + b. g(x) has the greater y-intercept.
