What is the largest organ in your body?
Jack must score 28 problems correct. To get a 92% he must answer 92% of the 30 questions right. which means 0.92*30=27.6, but it is not possible to score 0.6 of a problem right so you would round to 28, which guarantees Jack scores a 92 because if we round down, Jack would score less than a 92
It should be 35, if that is an answer choice.
Answer:
1 + i
Step-by-step explanation:
To rationalize multiply numerator and denominator by (2 + i )
![\frac{3+i}{2-i}= \frac{3+i}{2-i} \times \frac{2+i}{2+i} = \frac{(3+i)(2+i)}{(2-i)(2+i)} = \frac{6+3i+2i-1}{4-(-1)} = \frac{5+5i}{5} = 1 + i](https://tex.z-dn.net/?f=%5Cfrac%7B3%2Bi%7D%7B2-i%7D%3D%20%5Cfrac%7B3%2Bi%7D%7B2-i%7D%20%5Ctimes%20%5Cfrac%7B2%2Bi%7D%7B2%2Bi%7D%20%3D%20%5Cfrac%7B%283%2Bi%29%282%2Bi%29%7D%7B%282-i%29%282%2Bi%29%7D%20%3D%20%5Cfrac%7B6%2B3i%2B2i-1%7D%7B4-%28-1%29%7D%20%3D%20%5Cfrac%7B5%2B5i%7D%7B5%7D%20%3D%201%20%2B%20i)
