Step-by-step explanation:
First calculate the z-score.
z = (x − μ) / σ
z = (11.07 − 11.5) / 2.7
z ≈ -0.16
From a z-score table:
P(z<-0.16) = 0.4364
The proportion of babies that weigh less than 11.07 lbs is 0.4364.
Answer:
D. y =
Step-by-step explanation:
The solutions to this graph (meaning when y equals 0 or when the graph crosses the x-axis) are 4 and 5.
The only answer choice that has the solutions 4 and 5 when you factor it out is D.
Here's the proof:

Factors of 20: - 5 & -4
Sums that add up to -9: -5 + (-4)

(factor the first two terms and the last two terms separately)


(x - 5) (x - 4)

Answer:
The answer is -4.5
Step-by-step explanation:
according to my calculation
Y-5 = 3(x-4)
y-5 = 3x - 12
y = 3x - 7
