Remember the quadratic formula determinant?
If b^2 -4ac < 0, a complex root exists.
So for this problem, m^2 - 4q is the determinant, and if less than 0, is complex.
So a=-m/2 and b=(1/2)SQRT(m^2 - 4q)
Answer:
B. 3
Step-by-step explanation:
A common difference in an arithmetic sequence is the value the terms in the sequence vary from one to another.You can find one term to another by adding or subtracting the common difference.
In this case, the terms are 2,5,8,11,.....
From the first term to the second term, the difference is, 5-2=3
From the second term to the third term, the difference is, 8-5=3
From the third term to the fourth term the difference is=11-8=3
Hence the common difference in this arithmetic sequence is 3
The answer is B.
If a coin is flipped 14 times and lands on heads 10 times the fraction would equal to 10/14.
10/14 simplifies to 5/7.
