Using the following image, find the slope of the line.

dexar [7]

Answer:

-3

Step-by-step explanation:

To find slope you first need to pick to points where the line crosses a corner.

Slope= $\frac{Rise}{Run}$

I'm using the points (0,-2) and (-1,1). You can either count up and over for the slope or use the slope equation

$\frac{y2-y1}{x2-x1}$

y2=second y point

y1=first y point

x2=second x point

x1=first x point

$\frac{1-(-2)}{-1-0}$ Now you just solve

$\frac{3}{-1}$ or -3

By accident, four burned-out bulbs have been mixed in with 20 good ones. Ken is replacing old bulbs in his house. If he selects

ollegr [7]

We will be using the fact that $P(A \, and \,B) = P(A) \cdot P(B)$ , where $P(A)$ is the probability that the first bulb works and $P(B)$ is the probability that the second bulb works.

The probability that the first bulb works is $\frac{20}{24} = \frac{5}{6}$ . However, when we take one out (given that the first bulb works) we now have 19 working bulbs and 4 bad ones. This means that the probability that the second bulb works is $\frac{19}{23}$ .

Now, we can find our final probability:

$\dfrac{5}{6} \cdot \dfrac{19}{23} = \boxed{\dfrac{95}{138}}$
