Answer: 216
Step-by-step explanation:
6 x 12 x 3
There are 3 tolls where Stephanie pays $ 4.05.
<h3>What is Distance?</h3>
The distance between two points is the length of the path connecting them.
Here,
Distance covered by Stephanie = 12 1/4 miles
= 12.25 miles
Distance between two toll tax = 3 1/2 miles
= 3.5 miles
Number of Tolls = Total distance covered / Distance between two tolls
= 12.25 / 3.5
= 3.5
≈ 3 tolls.
Cost of 1 toll = $ 1.35
Total amount paid on toll = 3 X 1.35
= $ 4.05
Thus, there are 3 tolls where Stephanie pays $ 4.05.

Step-by-step explanation:
Answer:
If you are to express 5000 in scientific notation form, it would be:
5 · ![10^{3}](https://tex.z-dn.net/?f=10%5E%7B3%7D)
Step-by-step explanation:
Looking at it, there is only 1 sig fig (significant figure) and this means if you are to change it to number from between 1 - 10
it would be: 5
so it would look like 5.000 or just 5.
5,000. vs. 5.000 are both completely different things, that are expressed in different ways. But in this case, you can see that we have move the decimal place 3 times, which is why we have ![10^{3}](https://tex.z-dn.net/?f=10%5E%7B3%7D)
That is how you get your answer!
we know that
P(both parts defective) = P(1st is defective) * P(2nd is defective)
Probability of 1st detective:
total parts =50
number of defects =6
so,
P(1st is defective)
![=\frac{6}{50}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B6%7D%7B50%7D)
Probability of 2nd detective:
total parts =49
number of defects =5
so,
P(2nd is defective)
![=\frac{5}{49}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B5%7D%7B49%7D)
Probability of both detective:
P(both parts defective) is
![=\frac{6}{50} *\frac{5}{49}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B6%7D%7B50%7D%20%2A%5Cfrac%7B5%7D%7B49%7D)
