susan bought a calculator for $120. She had to pay a sales tax of 10% on the price. How much change would she receive from $140?

guapka [62]

Well for starters 10% of 120$ is 12$. 120+12=134...

This means 140 - 134=6

Answer: $6 of change

You solved a linear system with two equations and two variables and got the equation o=-8. how many solutions does the system of

Luda [366]

If you simplified a two-equation system and all variables were eliminated, two outcomes are possible.

If the final equation is a true equation, like 3=3, then the system has an <em>infinite number of solutions </em> (the equations graph the same line, and all points appear on both graphs)

If the final solution is a mathematically false equation, like 0=-8, the system has no solution. The lines are parallel and never intersect (have a solution)

Can someone show me how to do Mean absolute deviation

morpeh [17]

To find the mean of a set, add up all of the numbers and divide by how many numbers you have. For the first set:
$\mu=\frac{10.7+2.4}2=\frac{13.1}2=6.55$
For the second set:
$\mu=\frac{13.7+2.5}2=\frac{16.2}2=8.1$

To find the mean absolute deviation, (MAD) find the mean of the distances of each number from the mean.
For the first set:
$MAD=\frac{|10.7-6.55|+|2.4-6.55|}2=\frac{4.15+4.15}2=\frac{8.3}2=4.15$
For the second set:
$MAD=\frac{|13.7-8.1|+|2.5-8.1|}2=\frac{5.6+5.6}2=\frac{11.2}2=5.6$
Note that when you only have two data points the mean is directly between them, which is why the distances are the same.

The means-to-MAD ratio is simply that, divide one by the other and that's it.
For the first set:
$6.55\div4.15=1.57831325$
For the second set:
$8.1\div5.6=1.44642857$
