Answer:
5
Step-by-step explanation:
40 divided by 16 = 2.5
2*2.5=5
The complex number is given as: 2-8i
So for conjugate, you just flip the sign of the imaginary part:
2+8i will be the answer
You need to foil, The answer is D
Answer:
C. 2/3
Step-by-step explanation:
4/6 is equivalent to 2/3 (divide by 2)
Since 74% of the middle area is bounded, this means that
there is 13% on the left side, and another 13% on the right side.
P (left) = 0.13
P (right ) = 1 - 0.13 = 0.87
At this P values, the z scores are approximately:
z score (left) = -2.22
<span>z score (right) = 1.13</span>
