Solve the following systems of 3-variable linear equations.

Zina [86]

Answer:

x = 9/25, y = 7/25, z = 4/25

Explanation:

step 1: solve for y in first equation to use substitution

y = -2x + 1

step 2: insert into second equation to eliminate y variable and work with two variables

3(-2x+1) + z = 1 (now distribute)

-6x + 3 + z = 1 (bring over the -3)

-6x + z = -2

step 3: now left with -6x + z = -2 and x + 4z = 1, so eliminate z

-6x + z = -2 (multiply by 4)

4(-6x + z = -2)

-24x + 4z = -8

x + 4z = 1 (brought down third equation)

-25x = -9

x = 9/25

then just plug in x into the third equation to solve for z, followed by plugging it into the first equation to solve for y. you should end with y = 7/25 and z = 4/25

Which of the following choices are binomial random variables?

Vlad [161]

A binomial random variable is one based on a given number of specified

outcomes from a given number of trials.

The choice that is a binomial random variable is Choice B; Amelia rolls 5 fair dice. Let D equals the number of dice that show a value greater than 3.

Reasons:

A binomial random variable is the variable that represents the number of

times a specified event occurs in a given number of trials.

From the above definition of the binomial random variable, we have;

The binomial random variable is the option;

Choice B Amelia rolls 5 fair dice. Let D equals the number of dice that show

a value greater than 3, because, of the following;
