Answer: 9 m + 7 n - 6 mn + 4 m
Step-by-step explanation:
m + 3 n + 6 mn - 4 .... for this expression , it is already in its simplified form as we can not add any term together because they are not have the same variables.
9 m + 7 n - 6 mn + 4 ..... this also is already simplified
7 m - 9 n - 6 mn + 4 ..... the same thing with this
9 m + 7 n - 6 mn + 4 m .... this particular can still be further simplified because we have 9m and 4m having the same variable and we can therefore add them together , the simplified form of the expression will be
13m + 7n - 6mn
The answer to this question is C.

Let the null hypothesis be that the agent's claim is correct. Using a standard normal probability table we find:

The p-value 0.14 is much larger than alpha = 0.01, so we cannot reject the agent's claim.
When you multiply two complex numbers given in polar form, the argument of the product is the sum of the arguments of the factors. Meanwhile, the modulus of the product is the product of the moduli of the factors.
In this case, you'd have

and the modulus would simply be

. Since

we would expect the final product to fall in the first quadrant.
