Write the System of linear equations represented by the augmented major to the right use X,Y,Z for the variablesWrite the equati

Marizza181 [45]

On the augmented matrix, each row represents an equation of the linear system. From left to right, the first three elements of the row represent the coefficients of the variables in order, the last element represent the right side of the equation.

On the third row we have the elements 3 8 0 4, which gives to us the following equation

$\begin{gathered} 3\cdot x+8\cdot y+0\cdot z=4 \\ 3x+8y=4 \end{gathered}$

ind the probability of answering the two multiple choice questions correctly if random guesses are made. Assume the questions ea

algol13

Answer: a. 0.04

Step-by-step explanation:

Given : Number of multiple choice questions = 2

Choices given in each question = 5

Since only one choice is correct out of 5.

So, the probability of selecting the correct answer = $\dfrac{1}{5}$

Also, both questions are independent of each other.

It means , The probability of answering the two multiple choice questions correctly if random guesses are made

=( Probability of selecting the correct answer in question 1 ) x ( Probability of selecting the correct answer in question 2 )

= $\dfrac{1}{5}\times\dfrac{1}{5}= 0.04$

Hence, the required probability =0.04
