Answer:
90(8) + 2(38) = 270 + 76 = 346p
Step-by-step explanation:
Yes, yes it is; well done.
Answer:
Option 2 is right
Step-by-step explanation:
Given that

We can write this in polar form with modulus and radius

Hence angle = 60 degrees and

Since we have got 5 roots for z, we can write 60, 420, 780, etc. with periods of 360
Using Demoivre theorem we get 5th root would be
5th root of 2 multiplied by 1/5 th of 60, 420, 780,....
![z= \sqrt[5]{2} (cos12+isin12)\\z=\sqrt[5]{2} (cos84+isin84)\\\\z=\sqrt[5]{2} (cos156+isin156)\\\\z=\sqrt[5]{2} (cos228+isin228)\\\\z=\sqrt[5]{2} (cos300+isin300)\\](https://tex.z-dn.net/?f=z%3D%20%5Csqrt%5B5%5D%7B2%7D%20%28cos12%2Bisin12%29%5C%5Cz%3D%5Csqrt%5B5%5D%7B2%7D%20%28cos84%2Bisin84%29%5C%5C%5C%5Cz%3D%5Csqrt%5B5%5D%7B2%7D%20%28cos156%2Bisin156%29%5C%5C%5C%5Cz%3D%5Csqrt%5B5%5D%7B2%7D%20%28cos228%2Bisin228%29%5C%5C%5C%5Cz%3D%5Csqrt%5B5%5D%7B2%7D%20%28cos300%2Bisin300%29%5C%5C)
Out of these only 2nd option suits our answer
Hence answer is Option 2.
Answer:
Situation Best measure
1. The weights of wrestlers on the team varies by 74 lbs. range
2. The most popular M&M's color is green. mode
3. The mean price for an mp3 download is $1.96. mean
4. Half of the students in 3rd hour PE are 15 or older. median
Step-by-step explanation:
1. The weights of wrestlers on the team varies by 74 lbs. This is the range, the difference between the maximum and the minimum value.
2. The most popular M&M's color is green. This is the mode, the value more repeated.
3. The mean price for an mp3 download is $1.96. This is the mean.
4. Half of the students in 3rd hour PE are 15 or older. This is the median, the value in the half of the values
