Answer:
2
Step-by-step explanation:
common ratio r=an/an-1
=-30/-15 =2
Answer:
Step-by-step explanation: if you want to obtain the probability that x<em> </em>
-3 , then you need to add the probability for the cases x=-3 and x=-5.
p=0.13+0.17= 0.3
answer=0.3
Answer:
Step-by-step explanation:
1. You just plot the points
2. To plot the line you have to find the slope and y-intercept
Slope =
=
= 
Slope = 
Y-intercept = 
Y-intercept: y - 15 =
(x - 2)
y - 15 =
+ 15
Add 15 to both sides
y =
x + 30 this is the equation of the line.
So you start with the starting point and then the slope!
