The discriminant is
which is 0.
Since the discriminant is 0, there is only one real solution.

I^3=-i
therefor -27i=(3i)^3
so we can get a sum of 2 perfect cubes
a^3+b^3=(a+b)(a^2-ab+b^2)
so
remember that i²=-1
x^3+(3i)^3=(x+3i)(x²-3xi-1)
Calculate the mean, median, and mode of the following set of data. Round to the nearest tenth. 12,7,12,9,2,15,6,6,6,1,11

Answer:
Mean: 7.9
Median: 7
Mode: 6
Step-by-step explanation:
Sort the date set!
1, 2, 6, 6, 6, 7, 9, 11, 12, 12, 15
Then start by finding the mean of the data set!
Mean: the sum of all numbers divided by the amount of numbers
Mean = 1 + 2 + 6 + 6 + 6 + 7 + 9 + 11 + 12 + 12 + 15 = 87 divided by 11 = 7.9
Median: middle number in the data set
Data set: 1, 2, 6, 6, 6, 7, 9, 11, 12, 12, 15
Median = 7 because it is in the middle
Mode: the number that is being used the most
Data set: 1, 2, 6, 6, 6, 7, 9, 11, 12, 12, 15
Mode = 6 because it is used 3 times
