Answer:
y= 3x + 3
Step-by-step explanation:
From the graph we get 2 points: (-1,0) and (0,3)
(0,3) tells us that b = 3
and we use the equation 
to calculate m
m = 
= 3/1 = 3
so plugging m and b into y = mx + b gives us
y = 3x + 3
Answer:
area: 24
lateral area: 36
total area: I am not sure.
volume: 24
Step-by-step explanation:
area: length times width
lateral area: (perimeter of base) times height
total area: I do not know, sorry.
volume: length times width times height.
Answer: Events A and B are independent.
=============================================
Explanation:
Note how,
P(A)*P(B) = 0.5*0.2 = 0.1
which matches exactly with P(A and B) = 0.1
Therefore,
P(A and B) = P(A)*P(B)
is a true statement. This further leads to events A and B being independent.
