Answer:
Step-by-step explanation
First, let's remember the equation for point-slope form and how to find the 'm' value:

Now plug your m value and (x1, y1) into point-slope form:

Answer:
choice C: x2 -3x -3
Step-by-step explanation:
(3x^2-7x+2)-(2x^2-4x+5)
becomes
3x^2-7x+2 -2x^2+4x-5
adding
3x^2-2x^2 -7x+4x +2-5
which is
x^2 -3x -3
Both of these conditions must be true in order for the assumption that the binomial distribution is approximately normal. In other words, if
and
then we can use a normal distribution to get a good estimate of the binomial distribution. If either np or nq is smaller than 5, then a normal distribution wouldn't be a good model to use.
side note: q = 1-p is the complement of probability p
Because 3 / 6 = 0.5 and 4.5 / 9 = 0.5, the scale factor is 0.5 ;
