Answer:

$m=\frac{15}{8}$

Step-by-step explanation:

$-6\left(1-m\right)=9-2m$

$-6(1-m)=-6+6m$

$-6+6m=9-2m$

Add 6 to both sides:-

$-6+6m+6=9-2m+6$

$6m=-2m+15$

Now, add 2m to both sides:-

$6m+2m=-2m+15+2m$

Divide both sides by 8:-

$\frac{8m}{8}=\frac{15}{8}$

$m=\frac{15}{8}$

Auden rolled two number cubes and recorded the results. What is the experimental probability that the

faust18 [17]

Answer:

$Pr = \frac{5}{7}$

Step-by-step explanation:

Given

$n = 7$ -- rolls

Required

$P(sum > 5)$

From the attached table, the outcomes whose sum are above 5 are"

$sum>5 = \{\#2,\#3,\#4,\#5,\#6\}$

$n(sum > 5) = 5$

So, the probability is:

$Pr = \frac{n(sum > 5)}{n}$

This gives:

$Pr = \frac{5}{7}$

On your own paper, graph the system of equations and identify the solution:

notsponge [240]

The equations y = 3x - 4 and y = 3x + 1 are linear equations

The equations have no solution

<h3>How to determine the solution of the equations?</h3>

The equations are given as:

y = 3x - 4

y = 3x + 1

Next, we plot the graph of the equations y = 3x - 4 and y = 3x + 1

From the graph (see attachment), we can see that the equations do not have a point of intersection

Hence, the equations has no solution
