Answer:

The sample size must be greater than or equal to 756

Step-by-step explanation:

The formula to calculate the error of the proportion is the following

$E=z_{\alpha/2}*\sqrt{\frac{p(1-p)}{n}}$

where p is the proportion, n the sample size, E is the error and z is the z-score for a confidence level of 95%

For a confidence level of 95% $z_{\alpha/2}=1.96$

We know that for this case $p=0.23$

We require that the error be 0.03 as maximum

Therefore we solve for the variable n

$z_{\alpha/2}*\sqrt{\frac{p(1-p)}{n}}\leq0.03\\\\1.96*\sqrt{\frac{0.23(1-0.23)}{n}}\leq0.03\\\\\sqrt{\frac{0.23(1-0.23)}{n}}\leq \frac{0.03}{1.96}\\\\(\sqrt{\frac{0.23(1-0.23)}{n}})^2\leq (\frac{0.03}{1.96})^2\\\\\frac{0.23(1-0.23)}{n}\leq (\frac{0.03}{1.96})^2\\\\\frac{0.23(1-0.23)}{(\frac{0.03}{1.96})^2}\leq n\\\\n\geq\frac{0.23(1-0.23)}{(\frac{0.03}{1.96})^2}\\\\n\geq756$

Answer:

46 is the 15th term.

Step-by-step explanation:

In this question they have given us the function 3x + 1 to determine the 15th term in the table. X = the input or the numbers in that column. Now we must substitute x in our function to figure out the output.

Example:

3(1) + 1 = 4

So for the output for 1 the answer would be 4. You must follow this rule for 0 and 2 as well.

For 15 we must substitute 15 for x.

3(15) + 1 = 46

So 46 would be the 15th term.
