The answer to the question
Answer:
mean = 11.2 = 11
Step-by-step explanation:
mean = average = (10+11+10+12+10+11+13+13+11+11)/10 = 11.2=11
Answer:
8 + i
Step-by-step explanation:
What you need to simplify this is the following "definitions" of i to different powers.
![i^1=i](https://tex.z-dn.net/?f=i%5E1%3Di)
![i^2=-1](https://tex.z-dn.net/?f=i%5E2%3D-1)
![i^3=i^2*i=-1*i=-i](https://tex.z-dn.net/?f=i%5E3%3Di%5E2%2Ai%3D-1%2Ai%3D-i)
![i^4=1](https://tex.z-dn.net/?f=i%5E4%3D1)
Now we can sub these in for the various powers of i in our expression:
![6(1)+6(-i)-2(-1)+\sqrt{-1*49}](https://tex.z-dn.net/?f=6%281%29%2B6%28-i%29-2%28-1%29%2B%5Csqrt%7B-1%2A49%7D)
Simplifying a bit:
![6-6i+2+\sqrt{i^2*49}](https://tex.z-dn.net/?f=6-6i%2B2%2B%5Csqrt%7Bi%5E2%2A49%7D)
Since we know that the square root of i-squared is i, and that the square root of 49 is 7, we can get rid of the radial sign as follows:
6 - 6i + 2 + 7i
And the final answer, in a + bi form, is
8 + i

35 people paid a total of $245 for admission to a local soccer game. What is the price of admission?
Answer: We are given that 35 people paid total of $245 for admission.
Now we need to find the price of one admission. To find the price of one admission we need to divide the total amount paid by the number of people.
Therefore, the price of admission is:
7
