Answer:
0.0151 is the probability that adult men are at most 59 inches or at least 74 inches.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 68 inches
Standard Deviation, σ = 2.75 inches
We are given that the distribution of heights of adult men is a bell shaped distribution that is a normal distribution.
Formula:
P(height between 59 and 74)
0.0151 is the probability that adult men are at most 59 inches or at least 74 inches.

Answer:
The rate of change of the distance between the cars at that instant is 5.46 meters per second
Step-by-step explanation:
Speed of first car = 7 m/s
Speed of second car = 3 m/s
At instant, distance of first car from intersection = 5 meters
distance of second car from intersection = 12 meters
Therefore, we have
Distance between both cars at intant = √(12² + 5²) = 13 m
Rate of change of distance is given by;
2ddd/dt = d(x² + y²)/dt = 2xdx/dt + 2ydy/dt
= 26dd/dt = 2×5×7 + 2×12×3 = 142
dd/dt = 142/26 = 5.46 m/s.
That is the rate of change of the distance between the cars at that instant = 5.46 meters per second.
