Answer:
By power of a point, AC⋅CB=DC⋅CE. That is, 12⋅12=6⋅(2R–6).
Then, R=15.
Answer:
A 95% confidence interval for the mean number of months elapsed since the last visit to a dentist, is ![[5.79063, 28.20937]](https://tex.z-dn.net/?f=%5B5.79063%2C%2028.20937%5D)
Step-by-step explanation:
We will build a 95% confidence interval for the mean number of months elapsed since the last visit to a dentist. A (1 - 
) x100% confidence interval for the mean number of months elapsed since the last visit to a dentist with unknown variance and is given by:
![[\bar x -T_{(n-1,\frac{\alpha}{2})} \frac{S}{\sqrt{n}}, \bar x +T_{(n-1,\frac{\alpha}{2})} \frac{S}{\sqrt{n}}]](https://tex.z-dn.net/?f=%5B%5Cbar%20x%20-T_%7B%28n-1%2C%5Cfrac%7B%5Calpha%7D%7B2%7D%29%7D%20%5Cfrac%7BS%7D%7B%5Csqrt%7Bn%7D%7D%2C%20%5Cbar%20x%20%2BT_%7B%28n-1%2C%5Cfrac%7B%5Calpha%7D%7B2%7D%29%7D%20%5Cfrac%7BS%7D%7B%5Csqrt%7Bn%7D%7D%5D)
![[17 -2.7764 \frac{9.0277}{\sqrt{5}}, 17 +2.77644 \frac{9.0277}{\sqrt{5}}]](https://tex.z-dn.net/?f=%5B17%20-2.7764%20%5Cfrac%7B9.0277%7D%7B%5Csqrt%7B5%7D%7D%2C%2017%20%2B2.77644%20%5Cfrac%7B9.0277%7D%7B%5Csqrt%7B5%7D%7D%5D)
A 95% confidence interval for the mean number of months elapsed since the last visit to a dentist, is
Sum means addition . thus it is x+3,
Answer:
Something is missing from your question. However, the answer is most likely y = 50x
Step-by-step explanation:
For example if you are travelling in a car at 50mph then distance in miles y in terms of the number of hours x would be y = 50x
Answer:
2nd option because the number next to the x is the slope (3) and the added number is your intercept (4)
