Answer:
B
Step-by-step explanation:
When the function is less than but equal to and it's opposite are always solid dots. By this you can do simple process of elimination.
Given:
A line passes through (1,-2) and is perpendicular to 
.
To find:
The equation of that line.
Solution:
We have, equation of perpendicular line.
Slope of this line is
Product of slope of two perpendicular lines is -1.
Now, slope of required line is 
and it passes through (1,-2). So, the equation of line is
where, m is slope.
Therefore, the equation of required line is .
Answer:
Step-by-step explanation:
The greatest common favor is 5
-0.4 because it is 3.6 - 4
Answer: 7/75
Step-by-step explanation: An event may either be dependent or independent, depending on the effect the outcome of such event has on other events. A dependent events is one in which it's out ime is affected by the outcome of another event. On the other hand an independent event is not affected by the outcome of another event.
The event described above is a dependent event, because the outcome of my first try or pick will affect the possible outcome of my friend's first try.
Candy dish :
5 butterscotch ; 8 peppermint ; 12 chocolate
I and my friend both want peppermint:
P = required outcome ÷ Total possible outcome
Total possible outcome = 5+8+12 = 25
P(I pick peppermint on my first try) = 8/25
P(my friend picks peppermint on her first try) = 7/24
If I pick first, the outcome of my friend's event has been affected from the original
P = (8/25) × (7/24)
P = 56/600
P = 7/75
