Answer:
7 I believe. y=mx+b where the m is the slope and the b is the y intercept
Answer:
a) 2 accidents per day
b) .7071 accidents
Step-by-step explanation:
a) The mean is the sum of each possible number of accidents multiplied by its respective probability. So,
E(x) = (0)(.1) + (1)(.2) + (2)(.45) + (3)(.15) + (4)(.05) + (5)(.05) = 2
b) The variance V(x) = E(x^2) - E(x)^2, and the standard deviation is the square root of the variance. So,
V(x) = E(x^2) - (2)^2
= (0)(.1) + (1)(.2) + (4)(.45) + (9)(105) + (16)(.05) + (25)(.05) - 4 = 0.5
sqrt(0.5) = .7071
Answer:
-2
Step-by-step explanation:
Since we are adding 3 to the x-coordinate and subtracting 1 from the y-coordinate, (-5, 2) becomes (-2, 1).
<span>I dont think any of these are. I get a linear factor of (x-2)</span>
