Answer: 2 hours

Explanation: As Jenny left the hospital 3 hours before Kristin and was travelling at 30 km/hour she should have gotten 90 km before Kristin started driving. As Kristin was travelling at 75 km/hour she will get 45 km closer to Jenny every hour (30-75= (-45)). 45 km/90 km= 2 hours to catch up.

Answer:

Mean = 30

standard Deviation = 2.74

Step-by-step explanation:

Formula

mean = np

Standard Deviation = $\sqrt{npq}$

from the question = 40

P = 75% or 0.75

q = 1 - p = 1 - 75% or 1 - 0.75

To find mean

mean = 40 x 0.75

= 30

For Standard Deviation (SD)

Standard Deviation = $\sqrt{npq}$

= $\sqrt{40 X 0.75 X 0.25$

= $\sqrt{7.5}$

:. Standard Deviation = 2.74
