(10x + 4) + (5x-4) ≈ 180

solve for x and you get x≈12

plug 12 in to 5x-4 and you get 56

Giving a test to a group of students, the grades and gender are summarized below

GenaCL600 [577]

Answer:

59 / 71

Step-by-step explanation:

Given the data :

A B C Total

Male 20 10 13 43

Female 15 2 11 28

Total 35 12 24 71

The probability of randomly selecting a Student that got B ;

Probability = required outcome / Total possible outcomes

P(getting B) = number of students who got B / total number of students

P(getting B) = 12 / 71

Probability of getting B = 12 /71

Probability of not getting B = P(getting B)' = 1 - P(getting B)

Probability that student did not get "B" = 1 - 12/71 = 59 / 71

Construct an augmented matrix for this linear system: x − y − 4z = 5 2x 2z = 0 4x y z = 3.

Crazy boy [7]

The augmented matrix is,

$\left(\begin{array}{ccccc}1&-1&-4&|&5\\2&0&2&|&0\\4&1&1&|&3\end{array}\right)$

We have given system of linear equation is,

$x - y - 4z = 5,2x + 2z = 0 ,4x +y +z = 3.$

<h3>What is the meaning of augmented matrix?</h3>

In an augmented matrix, each row represents one equation in the system and each column represents coefficients (with signs) of variables or the constant terms.

So, the first row is

$1\ -1\ -4\ 5$

the second row is

$2\ 0\ 2\ 0$

and the third row is

$4\ 1\ 1\ 3$

Therefore the augmented matrix for this linear system is,

$\left(\begin{array}{ccccc}1&-1&-4&|&5\\2&0&2&|&0\\4&1&1&|&3\end{array}\right)$
