Question:
Morgan is playing a board game that requires three standard dice to be thrown at one time. Each die has six sides, with one of the numbers 1 through 6 on each side. She has one throw of the dice left, and she needs a 17 to win the game. What is the probability that Morgan wins the game (order matters)?
Answer:
1/72
Step-by-step explanation:
<em>Morgan can roll a 17 in 3 different ways. The first way is if the first die comes up 5, the second die comes up 6, and the third die comes up 6. The second way is if the first die comes up 6, the second die comes up 5, and the third die comes up 6. The third way is if the first die comes up 6, the second die comes up 6, and the third die comes up 5. For each way, the probability of it occurring is 1/6 x 1/6 x 1/6 = 1/216. Therefore, since there are 3 different ways to roll a 17, the probability that Morgan rolls a 17 and wins the game is 1/216 + 1/216 + 1/216 = 3/216 = 1/72</em>

Answer: 3.3 times 10^5 is bigger
Step-by-step explanation: 10^5= 10*10*10*10*10=100,000.
so 100,000 multiplied by 3.3 = 330,000
or 3.1 multiplied by 100,000 = 310,000 so it's obvious that 330,000 is bigger.
Answer:
The 95% confidence interval for the true mean speed of thunderstorms is [10.712, 13.688].
Step-by-step explanation:
Given information:
Sample size = 10
Sample mean = 12.2 mph
Standard deviation = 2.4
Confidence interval = 95%
At confidence interval 95% then z-score is 1.96.
The 95% confidence interval for the true mean speed of thunderstorms is
![CI=\overline{x}\pm z*\frac{s}{\sqrt{n}}](https://tex.z-dn.net/?f=CI%3D%5Coverline%7Bx%7D%5Cpm%20z%2A%5Cfrac%7Bs%7D%7B%5Csqrt%7Bn%7D%7D)
Where,
is sample mean, z* is z score at 95% confidence interval, s is standard deviation of sample and n is sample size.
![CI=12.2\pm 1.96\frac{2.4}{\sqrt{10}}](https://tex.z-dn.net/?f=CI%3D12.2%5Cpm%201.96%5Cfrac%7B2.4%7D%7B%5Csqrt%7B10%7D%7D)
![CI=12.2\pm 1.487535](https://tex.z-dn.net/?f=CI%3D12.2%5Cpm%201.487535)
![CI=12.2\pm 1.488](https://tex.z-dn.net/?f=CI%3D12.2%5Cpm%201.488)
![CI=[12.2-1.488, 12.2+1.488]](https://tex.z-dn.net/?f=CI%3D%5B12.2-1.488%2C%2012.2%2B1.488%5D)
![CI=[10.712, 13.688]](https://tex.z-dn.net/?f=CI%3D%5B10.712%2C%2013.688%5D)
Therefore the 95% confidence interval for the true mean speed of thunderstorms is [10.712, 13.688].
