Answer:
Option A.
Step-by-step explanation:
The given matrix is
![\left[\left.\begin{matrix}4 & 5\\ 7 & -4\end{matrix}\right|\begin{matrix}-16\\ 23\end{matrix}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cleft.%5Cbegin%7Bmatrix%7D4%20%26%205%5C%5C%207%20%26%20-4%5Cend%7Bmatrix%7D%5Cright%7C%5Cbegin%7Bmatrix%7D-16%5C%5C%2023%5Cend%7Bmatrix%7D%5Cright%5D)
We need to find the system of equations which is represented by the matrix.
In the given matrix first row represents the first equation and second row represents the second equation of the system of equations.
Let two variables are x and y.
First column represents the coefficients of x and second column represents the coefficients of y.
Numbers on the right side of the matrix represents the numbers which are right side of the equations.
Now, the required equations are
Therefore, the correct option is A.
Answer:
An article in Knee Surgery, Sports Traumatology, Arthroscopy (2005, Vol. 13, pp. 273?279) ?Arthroscopic meniscal repair with an absorbable screw: results and surgical technique? showed that only 25 out of 37 tears (67.6%) located between 3 and 6 mm from the meniscus rim were healed.
(a) Calculate a 95% two-sided confidence interval on the proportion of such tears that will heal. Round the answers to 3 decimal places.
Step-by-step explanation:
You arrange the numbers from lowest to highest,And you cover the numbers untill your left ith the number in the middle.
