Answer:
The frequency score is 3 3
If X is a random variable representing the number of children that end up having light-colored eyes, then X follows a binomial distribution with success probability p = 0.25 and number of trials n = 5.
The variance of a binomial distribution with these parameters is n p (1 - p), so the variance in this case would be
5 • 0.25 • (1 - 0.25) = 0.9375 ≈ 0.9
Answer:
C. -3x + y = 2
Step-by-step explanation:
(x₁,y₁) = (1,5)
m = 3
y - y₁ = m(x - x₁)
y - (5) = (3)(x - (1))
y - 5 = 3(x - 1)
y - 5 = 3x - 3
y = 3x +2
-3x + y = 2
Answer:
(6, 840) (5, 700) (3, 420) (4, 560)
Step-by-step explanation:
Use the one point that is completely filled out, (6, 840). Divide 840 by 6 and you get 140 so that is the slope. 5x140= what the y intercept will be, 700. 420/140= what the x intercept will be, 3. Now you can see a pattern which helps check your work. They are all decreasing pretty much, not really ordered much but. And finally the last point 4x140=560. Hope that helps! :)
