Rule start at 5 and 1/2 add 1 1/5

Margaret [11]

Answer:

The solution is $6\frac{7}{10}$ .

Step-by-step explanation:

It is given that rule start at $5\frac{1}{2}$ add $1\frac{1}{5}$ .

From the given information, we get the expression

$5\frac{1}{2}+1\frac{1}{5}$

Simplify the complex fraction.

$\frac{10+1}{2}+\frac{5+1}{5}$

$\frac{11}{2}+\frac{6}{5}$

Taking LCM, we get

$\frac{11\times 5+6\times 2}{2\times 5}$

$\frac{55+12}{10}$

$\frac{67}{10}$

$6\frac{7}{10}$

Therefore the he solution is $6\frac{7}{10}$ .

What is the standard deviation of the following data? 52 61 31 44 47 45 25 48 47

Elena-2011 [213]

Standard deviation is calculated by
1. calculate mean, m
2. calculate deviation of EACH entry of data set from the mean, i.e.
d=(x-m)
3. calculate mean of square of deviations (d^2)/n to get variance,v
4. take square-root of variance to get standard deviation.

For example,
To find the standard deviation of data set {3,7,8}
1. mean=(3+7+8)/3=6
2. deviations, di={3-6,7-6,8-6}={-3,1,2}
3. squares of deviations, di^2={9,1,4}
4. mean of squares of deviations=(9+1+4)/3=14/3
Standard deviation=sqrt(14/3)=2.16

For the given data set, if you follow the above steps, you would get
sum=400
mean=400/9
variance (mean square of deviations)=8246/81
standard deviation=sqrt(8246/81)=sqrt(8246)/9
