Answer:
The probability that a vehicle would be involved in a tire-related accident is
Step-by-step explanation:
We need to calculate the probability that a vehicule would be involved in a tire-related accident.
We know that, given a tire-related accident (TRA), the probability of it being deadly (D) is 0.05. That is:
We also know that the probability of being involved in a deadly tire-related accident is 0.000004
. We can express that as the probability of having a TRA multiplied by the probability of it being deadly:
Merging the two expressions we have:
So, first, we know that the whole angle must equal 90 because there's a right angle symbol, and right angles equal 90 degrees.
So, 43 + x + 3 must equal 90.
Or, 46 + x = 90
Then subtract 46 from both sides.
x = 90 - 46
x = 44
These would also be adjacent angles because they share the same vertex.
Firstly, the best thing to do is to expand the bracket.
To expand, you multiply everything at the front of the bracket by everything inside of the bracket.
4(s+2) becomes 4s (4*s) = 8 (4*2)
Then put this back into the equation, and this becomes;
4s+8+s-1
Then collect the like terms (these are the similar ones)
4s+s becomes 5s
8-1 becomes 7.
Therefore, the simplified equation is 5s+7
Hope this helps :)
