<span>Two cars start moving from the same point. one travels south at 48 mi/h and the other travels west at 20 mi/h. at what rate is the distance between the cars increasing four hours later? so its 400%</span>
Answer:
a) 0.3277
b) 0.0128
Step-by-step explanation:
We are given the following information in the question:
N(2750, 560).
Mean, μ = 2750
Standard Deviation, σ = 560
We are given that the distribution of distribution of birth weights is a bell shaped distribution that is a normal distribution.
Formula:

a) P (less than 2500 grams)
P(x < 2500)

Calculation the value from standard normal z table, we have,

b) P ((less than 1500 grams)
P(x < 1500)

Calculation the value from standard normal z table, we have,

The possible different outcomes are: c. 6 outcomes.
you can only count "e" once because even though it is in the bag twice, drawing it a second time would be the same outcame.
hope this help
Parameterize
