Answer:
infinite
Step-by-step explanation:
8(4n + 13) = 6n
Use distributive property so :8 (4n) = 32n and 8(13) = 104
32n + 104 = 6n
Subtract 32n from each side and you will get:
104 = 26n
then you divide each side by 26 and your answer will be:
n = 4
Answer:
Domain = (-∞,∞)
Range = (-∞,∞)
This is a linear function.
So, if you were to graph this you'd know that it crosses the x and y axis and continues on forever without stopping.
in that case the domain and range are considered infinite on both axes.
To find the rate, first you divide 180mi/3hr to get 60mph. On the first day they were traveling at a rate of 60mph. It says that on the second day, they drove at the same rate and drove 300 miles. This means you divide 300mi/60mph to get 5hr. They drove 5hr on the second day. And finally, the question asks how long they drove total, so you add 3hr+5hr to get 8hr total.
Answer is 8hr.
Given:
A spinner marked A, B, C is spun then a 6-sided die is rolled.
To find:
The probability of getting a B and then a 6.
Solution:
We know that,
![\text{Probability}=\dfrac{\text{Favorable outcomes}}{\text{Total outcomes}}](https://tex.z-dn.net/?f=%5Ctext%7BProbability%7D%3D%5Cdfrac%7B%5Ctext%7BFavorable%20outcomes%7D%7D%7B%5Ctext%7BTotal%20outcomes%7D%7D)
Total possible values for a spinner are 3. So, the probability of getting B, we get
![P(B)=\dfrac{1}{3}](https://tex.z-dn.net/?f=P%28B%29%3D%5Cdfrac%7B1%7D%7B3%7D)
Total possible values for a die are 6. So, the probability of getting 6, we get
![P(6)=\dfrac{1}{6}](https://tex.z-dn.net/?f=P%286%29%3D%5Cdfrac%7B1%7D%7B6%7D)
Now, the probability of getting a B and then a 6 is
![P(B,6)=\dfrac{1}{3}\times \dfrac{1}{6}](https://tex.z-dn.net/?f=P%28B%2C6%29%3D%5Cdfrac%7B1%7D%7B3%7D%5Ctimes%20%5Cdfrac%7B1%7D%7B6%7D)
![P(B,6)=\dfrac{1}{18}](https://tex.z-dn.net/?f=P%28B%2C6%29%3D%5Cdfrac%7B1%7D%7B18%7D)
The required probability is
.
Therefore, the correct option is D.
