Step-by-step explanation:
The total probability that the DeLorean makes the trip is:
P = P(engine) × P(at least 1 time circuit) × P(at least 2 capacitors)
P = P(engine) × (1 − P(0 time circuits)) × P(at least 2 capacitors)
P = 0.94 × (1 − ₄C₀ 0.75⁰ 0.25⁴) × (₃C₂ 0.8² 0.2¹ + ₃C₃ 0.8³ 0.2⁰)
P = 0.94 × (1 − 0.25⁴) × (0.384 + 0.512)
P = 0.83895
The reliability of the DeLorean is approximately 83.9%.

Okay I'll try to show it step by step
Step 1. So first you need to recognise that the diagram is a right angled triangle, with the right angle being at the bottom. This means we can do Pythagoras' Theorem.
Step 2. Now that you know you can use Pythagoras' Theorem, you can apply it. If you don't know, the theorem is a² + b² = c², with, in this case, a being 5 and b being 8. This means we can do 5² + 8² = 25 + 64 = 89.
Step 3. From the previous step, we now know that the length of the side including x is √89, and because we know that part of this side is 3, if we subtract 3 from √89 we get the value of x, so: √89 - 3 = 9.434 - 3 = 6.434, which is your answer.
I hope this helps!
Assuming you don't know the exact numbers, we can sequentially figure out the number of inches in a mile and seconds in a day
Inches in a mile:
There are 5280 feet in a mile.
5280*12 = 63360 inches in a mile
Seconds in a day:
There are 24 hours in a day
There are 24*60 = 1440 minutes in a day
There are 1440*60 = 86400 seconds in a day
There are more seconds in a day than inches in a mile.
We have been given a table of overnight low temperature for a four-day period. We are supposed to give a possible temperature for Wednesday.
We are told that the low temperature on Wednesday was between the second and third highest temperature.
Let us place our given temperatures from least to greatest order.
Sunday (-11), Thursday (-8), Friday (7), Sunday (18)
We can see that second and third highest temperatures are -8 and 7 respectively.
Any number between -8 and 7 will be a possible temperature for Wednesday. 3 can be a possible temperature for Wednesday as 3 is between -8 and 7.
