Answer:
(-4+3, -3) = (-1,-3)
Step-by-step explanation:
To divide these complex numbers you have to multiply by the conjugate of the denominator. That will look like this:
. Multiply straight across the top and straight across the bottom to get
. In the denominator, the 12i and -12i cancel each other out, which is nice. Now, in both the numerator and the denominator we have an i-squared. i-squared is equal to -1, so we will make that substitution in our solution:
. Doing the math on that we have
. We can simplify that as well as write it in standard form:
. Now we will get it into legit standard form, separating the real part of the complex number from the imaginary part.
. That can be reduced to its final answer of
. There you go!
Answer:

Step-by-step explanation:
Answer:
Obtuse
Step-by-step explanation:
I really don’t know which angle they’re asking for because the 140 degree angle is obtuse and the 40 degree angle is acute
The mean will go up, however little
The standard deviation will also go up.
hope this helps
