Answer:
Im not entirely sure, but i believe its 3i+1
Step-by-step explanation:
(i+2i)+(4-3)=
3i + 1
(you collect the like terms, and add them up together! it's that simple!)
Answer:
-57-176i
Step-by-step explanation:
You cannot solve this problem because it has two unknown values, on different sides of the equal sign. The closest you can get is 2p+5
Since there are 9 values, to find the Lower Quartile and Upper Quartile, you use the first 4 values and the last 4 values.
For Q1, you average the middle to values of your first 4 values since 4 is an even number. In this case (22+25)/2=23.5.
You do the same for Q3. (32+33)/2=32.5
For the interquartile range, you subtract Q1 from Q3. So, 32.5-23.5=9
Therefore, your lower quartile is 23.5, upper quartile is 32.5 and the interquartile range is 9.
