Answer:
The range of a function is the set of outputs the function can give
The y-axis on the graph shows as the output of the function
From the graph, we can see that the outputs of this specific function range from 0 to 5
Therefore, the range of this function is: [0 , 5]
Answer:
We are 95% confident that the true proportion of TV audience is between 65.15% and 65.85%
Step-by-step explanation:
-From the given information,
.
-We calculate the confidence interval using this value at 95% confidence level:
![CI=\hat p\pm z \sqrt{\frac{\hat p(1-\hat p)}{n}}\\\\\\=0.65\pm 1.96\times \sqrt{\frac{0.65\times 0.35}{12000}}\\\\\\=0.65\pm 0.0085\\\\\\=[0.6415,0.6585]](https://tex.z-dn.net/?f=CI%3D%5Chat%20p%5Cpm%20z%20%5Csqrt%7B%5Cfrac%7B%5Chat%20p%281-%5Chat%20p%29%7D%7Bn%7D%7D%5C%5C%5C%5C%5C%5C%3D0.65%5Cpm%201.96%5Ctimes%20%5Csqrt%7B%5Cfrac%7B0.65%5Ctimes%200.35%7D%7B12000%7D%7D%5C%5C%5C%5C%5C%5C%3D0.65%5Cpm%200.0085%5C%5C%5C%5C%5C%5C%3D%5B0.6415%2C0.6585%5D)
So, the 95% confidence interval is (0.6515,0.6585).
Hence, we are 95% confident that the true proportion of TV audience is between 65.15% and 65.85%.
Answer:
b
Step-by-step explanation:
There are two names that start with the letter M.
Answer:
1.D
2.B
Step-by-step explanation:
For the first one divide see which one is less which is D
For the second one Ive always used the method kcf keep change flip so you keep
the change ÷ to multiplication so then flip
so the equation would be
x
so multiply the 15 by 9 then you get 135 then divide by 2 so thats your answer
