28 (y - 1/7) = 28y - ?Rewrite, using the distributive property
Irina-Kira [14]

Given:

28(y-\frac{1}{7})=28y\text{ - ?}

To rewrite using distributive property, distribute the 28 to all values inside the parenthesis.

Thus, we have:

\begin{gathered} (28\ast y\text{ )-(28}\ast\frac{1}{7}) \\ =28y\text{ - 4} \end{gathered}

ANSWER:

28(y-\frac{1}{7})=28y\text{ - }4

28y - 4

Answer:

σˆ =

sPn

i=1 X2

Step-by-step explanation:

To obtain, the maximum likelihood ratio, we use the following method.

l(σ) = Xn

i=1 "

− log 2 − log σ −

|Xi

σ

#

Let the derivative with respect to θ be zero:

l

0

(σ) = Xn

i=1 "

−

σ

σ

Pn

i=1 |Xi

|

σ

= 0

and this gives us the MLE for σ as

σˆ =

Pn

i=1 |Xi

n

Again this is different from the method of moment estimation which is

σˆ =

sPn

i=1 X2
