If you want it estimated it would be .55 which would be 55/100 which would simplify to 11/20
1. To translate to the left, add to x.
The equation is: y = |x + 2|
2. To translate down, add to y.
The equation is: y + 2 = |x| OR y = |x| - 2 (subtract 2 from each side)
Hope this helps!
Area = πr^2
area = π(7)^2
area = 49π
By applying the definition of product between two <em>square</em> matrices, we find that
is equal to the matrix

<h3>What is the product of two square matrices</h3>
In this question we must use the definition of product between two <em>square</em> matrices to determine the resulting construction:
![\vec A \,\cdot \,\vec A = \left[\begin{array}{cc}1&2\\3&6\end{array}\right] \cdot \left[\begin{array}{cc}1&2\\3&6\end{array}\right]](https://tex.z-dn.net/?f=%5Cvec%20A%20%5C%2C%5Ccdot%20%5C%2C%5Cvec%20A%20%3D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D1%262%5C%5C3%266%5Cend%7Barray%7D%5Cright%5D%20%5Ccdot%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D1%262%5C%5C3%266%5Cend%7Barray%7D%5Cright%5D)

Answer: A. 0.4899 B. 14
Step-by-step explanation:
If X = random variable
then, the standard deviation of the sampling distribution of X = 
A.
GIven: 
The standard deviation of the sampling distribution of X = 
B. Let n be the sample size,

Hence, the required sample size = 14
