Step-by-step explanation:

a) 6-9b=3a

First:Subtract

3b=3a

Second: Devide

3b/3a

=(3÷3)(b÷a)

=1b/a

= b/a

B) 6b+2a=3a

First:Transpose (Group the like terms. signs will change.)

-3a+2a=-6b

=-1a=-6b

Second:Divide

=-1a/-6b:(-1÷-6)(a÷b)

=1a/6b

=a/6b

C)a/3=b+2

First: Transpose

a=3+2+b

=a/6+b

A family goes grocery shopping every week. in a month the costs of the groceries are $72.42, $91.50, $58.99, and $69.02. 5. what
frozen [14]
1) Mean
The mean is given by the sum of the data divided by the number of data (4, in this case):
\mu =   \frac{1}{N} \sum x_i = \frac{1}{4}(72.42+91.50+58.99+69.02) = \frac{291.93}{4}=72.98 $

2) Standard deviation
The standard deviation is given by:
\sigma =  \sqrt{ \frac{1}{N} \sum (x_i-\mu)^2 }
where \mu is the mean, that we already found at point 1), and N=4. Substituting data, we have:
\sigma =  \sqrt{ \frac{1}{4} ((-0.56)^2+(18.52)^2+(-13.99)^2+(-3.96)^2) } =
= \sqrt{ \frac{1}{4}  (554.71)} = \sqrt{138.68} =11.78 $
