Answer:
The probabilities that a flight is more than 140 minutes would be 32.2%.
Step-by-step explanation:
Given that a trip between New York and Chicago lasts between 120 and 150 minutes, with probabilities uniformly distributed within that time range, to calculate the probabilities that the trip lasts more than 140 minutes, we must perform the following calculation:
First, determine the range of minutes available for arrival. Thus, between 120 and 150, including both ends, there is a 31 minute difference (150-119). Therefore, since the 100% arrival probability is evenly distributed between these minutes, each minute has a 3.22% probability that the plane will arrive at that time (100/31 = 3.22).
Therefore, since the question points to a journey of more than 140 minutes, we must consider the time from the 141 minute journey, that is, 10 minutes between 141 and 150. Thus, the probabilities that the trip lasting more than 140 minutes will be 32.2%.
Answer:
Please rephrase, i cant understand the question
The distance the rock has to travel to hit the ground is 400ft.
400 = 16 * t^2divide both sides by 16 and take the square root.
<span>25=t^2
</span>
5=t
H= 12.4
I assume this is a rectangular prism. the formula is V=l*w*h
plug-in the known values
<span>V=3758.75 W=24.25 L=12.5
</span><span>3758.75 =24.25*12.5*H multiply terms
</span><span>3758.75=303.125H divide both sides by 303.125
12.4=H</span>
Answer:
5cm
Step-by-step explanation:
- In order to find the area of a 2d regular shape such as a square, you need to do length × width = area
- A square has four regular sides, which means they must all be the same length, which in turn means that we only need to find one number, and it must be the square root of 25.
So, the length of each side is 5cm.
Hope this helped!
