Um........its confusing to explain sorry
Answer:
The probability that at least two homeowners will set their switches to the same code is 100%.
Step-by-step explanation:
Consider the provided information.
The total number of code can be set with 0 or 1 is:
2×2×2×2×2×2×2=128
There are 128 different codes.
The probability that code is unique is 1/128
Now, the probability that all codes are unique is:
![[\frac{1}{128}]^{150}](https://tex.z-dn.net/?f=%5B%5Cfrac%7B1%7D%7B128%7D%5D%5E%7B150%7D)
Hence, the probability that all the codes are not unique is:
![1-[\frac{1}{128}]^{150} \approx 1](https://tex.z-dn.net/?f=1-%5B%5Cfrac%7B1%7D%7B128%7D%5D%5E%7B150%7D%20%5Capprox%201)
Because the value of
is very small
As they can set 128 different codes and there are 150 homes. So, at least two homeowners will set their switches to the same code is 100%.
Hence, the probability that at least two homeowners will set their switches to the same code is 100%.
First you find the length of the green rectangle by using a^2 + b^2 = c^2
So that means 4^2 + 7^2 = length of green
That equals 8.1 when you square root it.
Then, you use 8.1^2 + 3^2 (which is the green rectangle height) to find the red line using the same equation
So your answer is 8.6 cm.

Answer:
<em>f(10)=290</em>
Step-by-step explanation:
<u>Function Evaluation</u>
Given a function f(x) as an explicit expression, finding f(x=a) implies substituting the value of x by a in every instance it occurs.
We are given the function:

It's required to find f(10). We replace the x for 10:

Operating:



Thus, f(10)=290
