**translation please?**

Low German is an archaic dialect of the german language spoken in northern Germany. The terrain there is relatively flat, hence the name "Low".

**Albebra II**

The mean of the given numbers is 16.8. SD=sqrt(1/N sum((x-mean)^2)) =sqrt(1/9*((21-16.8)^2+(13-16.8)^2... =7.3

**Algebra II**

ME = 2 sqrt(.56(1-.56)/400) = 2 sqrt(.56(.44)/400) = 2 sqrt(.2464/400) = 2 sqrt(0.000616) = 2 x .0248 = 0.0496 or 4.96 percent margin of sampling error

**Physical Science**

The period is the inverse of the frequency, so it would be reduced to half.

**Geometry**

The preimage is the original position before translation, or P(-1,5)

**algebra**

First off, the word equation implies both sides of the expression are equal. a > b implies a - b > 0 If c is < 0 then c(a - b) < 0 or ca - cb < 0 or ca < cb
