Find the slope of this graph, thanks

Mathematics

Slope  =  (change in 'y') / (change in 'x')

If you find two points where the line goes through the corners of boxes,
then count up the 'y' boxes and the 'x' boxes between those two points,
you'll find that the line rises 3 y-boxes for each x-box.

The slope of the line is  3 .

Minchanka [31]

Answer:Let x = pay per hour as a carpenter and y = pay per hour as a blacksmith

Last week she worked 12 hours as a carpenter

earning 12x dollars

and 20 hours as a blacksmith

earning 20y dollars

and earned a total of $860

and those two things add up to 860.

Do the same with the other sentence, giving you a second equation.

Rational Exponent
lara [203]
The concept of radicals and radical exponents is tricky at first, but makes sense when we look into the logic behind it. 

When we write a radical in exponential form, like writing √x as x^(1/2), we are simply putting the power of the radical in the denominator (bottom number) of the exponent, and the numerator is the power we raise the exponent to, or the power that would be inside the radical. 
In our example, √x is really ²√(x¹), or the square root of x to the first power. For this reason, we write it as x^(1/2).

Let's say we wanted to write the cubed root of x squared, in exponential form. 
In radical form, it would look like this:
³√(x²) . This means we square x, and then take the cubed root.
In exponential form, remember that we take the power of the radical (3), and make that the denominator of the exponent, and keep the numerator as the power that x is raised to (2). 
Therefore, it would be x^(2/3), or x to the 2 thirds power. 

Just like when multiplying by a fraction, you multiply by the numerator and divide by the denominator, in exponential form, you raise your base number to the power of the numerator, and take the root of the denominator.

12. In Europe, 88% of all households have a TV. 51% of all households have a TV and VCR. What is the probability that a househol
PSYCHO15rus [73]

Answer:

0.579  is the probability that a household has a VCR given they have a TV.

Step-by-step explanation:

We are given the following in the question:

Probability of all households have a TV = 88% = 0.88

P(T) = 0.88

Probability of all households have a TV and VCR = 51% = 0.51

P(T\cap V) = 0.51

We have to find the probability that a household has a VCR given they have a TV.

The conditional probability is given by:

P(V|T) = \displaystyle\frac{P(V\cap T)}{P(t)} = \frac{0.51}{0.88} = 0.579

0.579  is the probability that a household has a VCR given they have a TV.
