Answer: 11.15
Step-by-step explanation:
10.2 + 12.1 = 22.3 is the total amount of points averaged each game together
22.3 divided by 2 + 11.15
11.15 is the average of the two players over the 10 games
Answer:
C (y=5x-7)
Step-by-step explanation:
First, you find the slope between the 2 points which is 5, then you use one of the points to form an equation.
You then find it's y=5x-7.

Answer:
The margin of error for the 95% confidence interval used to estimate the population proportion is of 0.0209.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of
, and a confidence level of
, we have the following confidence interval of proportions.
![\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}](https://tex.z-dn.net/?f=%5Cpi%20%5Cpm%20z%5Csqrt%7B%5Cfrac%7B%5Cpi%281-%5Cpi%29%7D%7Bn%7D%7D)
In which
z is the z-score that has a p-value of
.
The margin of error is of:
![M = z\sqrt{\frac{\pi(1-\pi)}{n}}](https://tex.z-dn.net/?f=M%20%3D%20z%5Csqrt%7B%5Cfrac%7B%5Cpi%281-%5Cpi%29%7D%7Bn%7D%7D)
In a clinical test with 2161 subjects, 1214 showed improvement from the treatment.
This means that ![n = 2161, \pi = \frac{1214}{2161} = 0.5618](https://tex.z-dn.net/?f=n%20%3D%202161%2C%20%5Cpi%20%3D%20%5Cfrac%7B1214%7D%7B2161%7D%20%3D%200.5618)
95% confidence level
So
, z is the value of Z that has a p-value of
, so
.
Margin of error:
![M = z\sqrt{\frac{\pi(1-\pi)}{n}}](https://tex.z-dn.net/?f=M%20%3D%20z%5Csqrt%7B%5Cfrac%7B%5Cpi%281-%5Cpi%29%7D%7Bn%7D%7D)
![M = 1.96\sqrt{\frac{0.5618*0.4382}{2161}}](https://tex.z-dn.net/?f=M%20%3D%201.96%5Csqrt%7B%5Cfrac%7B0.5618%2A0.4382%7D%7B2161%7D%7D)
![M = 0.0209](https://tex.z-dn.net/?f=M%20%3D%200.0209)
The margin of error for the 95% confidence interval used to estimate the population proportion is of 0.0209.
OK so my answer is from what you’ve just explained that means you multiply the six and the 114 is 684 so that means if you have to do that to 13 of them that means 684×13 is what your equation would be in the answer to 684×13 is 8892
