Answer: the mean is 44
Explanation: add up all the numbers and then divide by how many numbers there are
A. the polynomial can then be factored to (x+10)(x+2).
C,f and b I think because u only look at the x and nothing else but when u looking in a linear graph u do a the straight line test
1. D - Since it's random, everyone has an equal chance of being picked
2. B - Since the people are already registered voters it would be easier to get a response from them. Plus, picking ever 10th person makes it random.
3. false - a fair question wouldn't make assumptions about the population
4. B - "Don't you think" causes the answerer to be pushed towards saying yes
hope this helps :)
25 a² + 20 ab + 4 b²
for formula
find u,v such that: u.v = a
and u+v = b then group according to
=
factor out 5a from :
factor out 2b from :
=
factor out :
=
