No, it is an imaginary number.
Can't take the square root of a negative number without creating a method termed an imaginary number, which is the square root of -1 which they have used " i " to signify.
Then square root of -11.2 would be written Sqrt(11.2)i.  The Sqrt(11.2) = 3.3466
so the answer is 3.3466i

Often, variability is most usefully expressed in the same units as the original data. That's what <em>standard deviation</em> (square root of variance) does. In situations where that is the case, the variance is useful only for getting to the value of standard deviation.

What number is in the ten-thousandths spot of pi?
Nesterboy [21]

Answer:To figure out the value you have to look at all of the numbers from right to left.  You start with the ones place and get prgressively bigger going up by a multiple of 10 each time.  So you have the ones, tens, hundreds, thousands, ten thousands, etc.  In the number in your example, you have 3 ones, 4 tens (or 40), 1 hundred or (100), 0 thousands, and 5 ten thousands (50, 000).  You can write the number in expanded form to help you figure out the value.  50,000 + 100 + 40 +3.

I have 3 times as much money as my brother. Our total is $24. How much does each of us have?I have 3 times as much money as my b
musickatia [10]

Answer:

Brother's money  = $6

Money I have  = $18

Step-by-step explanation:

Hi, to answer this question we have to write an equation with the information given:

<em>I have 3 times as much money as my brother: </em>

Money I have = 3x  

Where x is the money that my brother has:

Brother's money = x

<em>Our total is $24 </em>

So, 3x+x =24

Solving for x

3x+x=24

4x =24

x =24/4

x = 6

Replacing with the value of x.

Brother’s money = x = $6

Money i have = 3x =3(6) = $18
