X-2 = 0
X = 2
The first one equals 16
Second equals 0, so that is correct
Third equals 0, so that is correct
Fourth equals -2, so that is wrong
So 8*200 is 1600.
1880-1600 is 280.
rate of change is 200.
initial is 280
Answer:
5/3 or 1.666...
Step-by-step explanation:
SLOPE: get the difference of each coordinate and divide them.
two points: A(2,7) and B(5,12)
we subtract ax from bx:
5 - 2 = 3, "dx"
and subtract ay from by:
12 - 7 = 5, "dy"
now we divide dy/dx:
5/3 or 1.666...
that's the slope
This can be solved by using the binomial distribution. The probability of guessing correctly is 0.5, and the probability of making a wrong guess is also 0.5.
