Answer:
99%
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.
In which
z is the zscore that has a pvalue of 
.
The margin of error is:
Sample proportion and same sample size, so what will determine the margin of error is z.
90% confidence level
So 
, z is the value of Z that has a pvalue of 
, so 
.
95% confidence level
So 
, z is the value of Z that has a pvalue of 
, so 
.
99% confidence level
So 
, z is the value of Z that has a pvalue of 
, so 
.
The 99% confidence interval has the largest margin of error.
Hi there! The answer is f(x), because it grows slower than g(x).
f(x) is a quadratic function (because as you can see the formula of f(x) is x^2 + 2). The function of g(x) is exponentional, and therefore it grows faster than f(x).
Answer:
It is not a function
Step-by-step explanation:
A function refers to a set of points/lines with this characteristic:
Each Y value has only one corresponding X value.
Meaning one X value cannot have multiple Y Values.
In this case, the X value of 2 has 2 different Y values, making it not a function.
Answer:
X is equals to 2
