Answer:
B. (13/3 - 3i)
Step-by-step explanation:
Given: (3i - 2/3) - (6i - 5)
Here we have to subtract.
To simplify we have to combine real numbers and complex number(i.e) terms with "i"
= 3i - 2/3 -6i + 5 [distributed the negative sign inside the parenthesis]
= -2/3 + 5 + 3i - 6i[Combine real numbers and complex numbers]
= 13/3 - 3i
Therefore, the answer is B. (13/3 - 3i)
Hope this will helpful.
Thank you.
Our goal is to solve for x
We will first add 7 to both sides
9x = 27
We will then divide both sides by 9
x = 3
Answer: The answer is b=1/4
Answer:
1.691
Step-by-step explanation:
Standard error of the mean is expressed as SEM = S/√n
S is the population standard deviation
n is the sample size (number of observation)
Given S = 27 and n = 255
SEM = 27/√255
SEM = 27/15.97
SEM = 1.691
Hence the standard error of the mean is 1.691
