<h3>
How the find the proportion?</h3>

Given:

Total sample: 3887

No that had no opinion: 1407

No that had at least one experience: 2480

Therefore, to find the proportion who had<em> no such experience</em> is:

Sample number/Total sample

1407/3887

=0.362

Find a12 of the sequence 1/4, 7/12, 11/12, 5/4

UNO [17]

1/4 = 3/12, and 5/4 = 15/12, so it looks like there's a common difference between terms of 4/12 = 1/3. The the $n$ -th term in the sequence is given recursively by

$\begin{cases}a_1=\frac14\\a_n=a_{n-1}+\frac13&\text{for }n>1\end{cases}$

By substitution, we get

$a_n=a_{n-1}+\dfrac13\implies a_n=\left(a_{n-2}+\dfrac13\right)+\dfrac13$

$a_n=a_{n-2}+\dfrac23$

and doing this again and again until we stop with an expression containing $a_1$ , we find that

$a_n=a_1+\dfrac{n-1}3$

$a_n=\dfrac{4n-1}{12}$

Then the 12th term in the sequence is

$a_{12}=\dfrac{4\cdot12-1}{12}=\boxed{\dfrac{47}{12}}$

Solve the inequality 7y-35<2(x-5)

AfilCa [17]

Answer:

x < 5

<u>Explanation:</u>

7*x-35-(2*(x-5))<0

(7x - 35) - 2 • (x - 5) < 0

Pull out like factors :

5x - 25 = 5 • (x - 5)

5 • (x - 5) < 0

Divide both sides by 5

Add 5 to both sides

x < 5
