I believe that the mean is 6
Answer:
the second one to the right
Step-by-step explanation:
the first one makes a square
the third sides are too tiny
the last one just doesnt make anything
The given expression is

And in the second factor, x is common. So on taking x out, we will get

We can expand it by distributing , that is


Combining like terms,

And that's the expanded form ., and the given expression can also be written in that way .
Answer:
a) 0.900
b) 0.400
Step-by-step explanation:
Let I = households getting internet
T = households getting television
Then I = 60%
and T = 80%
(Households that get both services)
a) Households getting at least one service, 
b) Those getting internet only = 
Those getting television only = 
Probability of getting exactly one service = 0.1 + 0.3 = 0.400
Point slope form
y - y1 = m(x - x1)
Plug in the given
slope = -4
Point ( 4, 1)
y - 1 = -4(x - 4)
y - 1 = -4x +16
add 1 to both sides
y = -4x + 17
Hope this helps!
