64/400 = 16/100 = .16 = 16%
Answer:
Synthetic division is another way to divide a polynomial by the binomial x - c , where c is a constant.
Step-by-step explanation:
Set up the synthetic division.
Bring down the leading coefficient to the bottom row.
Multiply c by the value just written on the bottom row.
Add the column created in step 3.
Answer:
The standard error of a proportion p in a sample of size n is given by:
Step-by-step explanation:
Central Limit Theorem
The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean and standard deviation , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean and standard deviation .
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean and standard deviation
In this question:
The standard error of a proportion p in a sample of size n is given by:
Answer:
1/6 I think
Step-by-step explanation:
<em><u>Question:</u></em>
The sum of first n terms of an AP is given by Sn= 2n square +3n. Find the sixteenth term of the AP
<em><u>Answer:</u></em>
16th term of AP is 65
<em><u>Solution:</u></em>
Given that,
<em><u>The sum of first n terms of AP is given by:</u></em>
Let nth term in AP be:
<em><u>Then the nth term is given as:</u></em>
Where, from given,
<em><u>Thus nth term is given as:</u></em>
<em><u>To find the 16th term, substitute n = 16</u></em>
Thus 16th term of AP is 65
