The mean of six numbers is 14. If one of the six numbers is removed, the mean becomes 5. What is the value of the number removed
Oliga [24]

Answer:

Remember, the mean is calculated by adding the scores together and then dividing by the number of scores you added. In this case, the mean would be 2 + 4 (add the two middle numbers), which equals 6. Then, you take 6 and divide it by 2 (the total number of scores you added together), which equals 3.

Step-by-step explanation:

Hope I helped.It's just a reminder of helpful things for means!

What is the sum of StartRoot negative 2 EndRoot and StartRoot negative 18 EndRoot? 4 StartRoot 2 EndRoot 4 StartRoot 2 EndRoot i
erma4kov [3.2K]

Adding  \sqrt{-2}\,\,and\,\,\sqrt{-18} we get 4\sqrt{2i}

Option C 4 StartRoot 2 EndRoot i is correct.

Step-by-step explanation:

We need to find the sum of: \sqrt{-2}\,\,and\,\,\sqrt{-18}

Finding sum:

\sqrt{-2}+\sqrt{-18}

\sqrt{-2} can be written as \sqrt{2}i

\sqrt{-18} can be written as \sqrt{18}i

We know 18 = 2x3x3 = 2x3^2 so,

\sqrt{2i}+\sqrt{2\times 3^2}i

\sqrt{2i}+3\sqrt{2}i

Adding like terms:

4\sqrt{2i}

So, adding  \sqrt{-2}\,\,and\,\,\sqrt{-18} we get 4\sqrt{2i}

Option C 4 StartRoot 2 EndRoot i is correct.
