The probability that the machine works in the morning is 50%. This means that out of 100 times it works, it will not overheat 50 times.
The probability that the overheats late if it worked in the morning is 15%. this means that 15% our of the 50 times in the morning when it worked will satisfy this condition, which is 7.5 - so if the machine runs 100 times, it will overheat only in the evening 7.5 times.
The probability that it will overheat only in the evening is 7.5%!

Answer:
110.9 feet
Step-by-step explanation:
The function that models the flight of the ball is
where f(x) is the vertical distance in feet and x is the horizontal distance the ball travels
If the ball hits the ground, then f(x)=0
The solution is given by the quadratic formula:
We substitute a=-0.02, b=2.2, and c=2 to get:
This implies that:
Since we are dealing with time,
To one decimal place, we have 110.9 feet
8
Step-by-step explanation:
- Critical Path Analysis is presented using the circle and arrow diagrams.
- Earliest Start Time = the earliest possible time of starting the activity
- An arrow running between two event circles shows the activity needed to complete that task.
- All arrows run left to right
- Time for doing just task E = 8 hours (as shown in the figure)
Answer:
D
Step-by-step explanation:
Remark
The circumference of a circle is 2 * pi * r
Given
The circumference (C) = 16 * pi
Solution
2 pi r = 16 pi Divide by 2*pi
r = 16 pi / (2*pi)
r = 8
