1/9=0.11111.....
so the correct option is (a).
Answer:
Option d.
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:
79 percent of adults age 18 years and older in the United States use the Internet.
This means that 
98% confidence level
So 
, z is the value of Z that has a pvalue of 
, so 
.
Which of the following should be used to find the sample size (n) needed?
We have to find n for which 
So the equation is:
Option d.
The first person who calculated pi was <span>Archimedes got really close however with the mathematics he had in his time he did not have decimal points nor could he use the number 0. So it has to latter once people recognize 0 as a number and the decimal point that we get what we have today. </span><span />

It has to be in order start with the x-axis then the y-axis
Answer: Option 'D' is correct.
Step-by-step explanation:
Since we have given that
3 times the square root of 2 +2 times the square root of 3 =3sqrt2+2sqrt3
We need to simplify the above expression.
In addition and subtraction, there is a rule of adding or subtracting of like terms is possible only.
But, here, √2 ad √3 are unlike term.
so, we cannot simplified it.
Hence, Option 'D' is correct.
Step-by-step explanation:
