In the question, they GIVE you the equation for the line:
y = 1.1 x + 1.37 .
When you look at the graph, you notice that the numbers
are actually thousands, so the equation is really
y = (1.1 thousand) x + (1.37 thousand)
or
y = 1,100 x + 1,370 .
The slope of the line is 1,100 .
Choice 'C' says that, because
the slope of any graph = (change in 'y') / (change in 'x') .
Answer:
![\frac{1}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B8%7D)
Step-by-step explanation:
In calculating probability, remember that "AND" means "MULTIPLICATION" and "OR" means "ADDITION".
Since we want the probability of red necklace AND yellow bracelet, we calculate individual probabilities and "MULTIPLY" them.
<u>Probability of red necklace:</u>
There are 4 necklaces and 1 of them is red, hence probability of red necklace is 1/4
<u>Probability of Yellow bracelet:</u>
There are 2 bracelet and 1 of them is yellow, hence probability of yellow bracelet is 1/2
Now, we multiply both to get our answer.
1/4 * 1/2 = 1/8
