What is the 97th term of the arithmetic sequence -16,2,20

MAXImum [283]

Answer:

1712

Step-by-step explanation:

Given arithmetic sequence is: -16,2,20

Here, a = - 16, d = 2 - (-16) = 2+ 16 = 18

n = 97, $a_{97}=?$

$\because a_n = a + (n-1)d\\\\\therefore a_{97}= - 16 + (97-1)\times 18\\\\\therefore a_{97}= - 16 + 96\times 18\\\\\therefore a_{97}= - 16 + 1728\\\\\therefore a_{97}=1,712\\\\$

Answer:

The 0 and 1 outcomes would be considered unusual.

Step-by-step explanation:

We can define as usual outcomes, the ones that fall between $\bar{x}\pm 3s$ .

According to a binomial distribution, s value is

$s=\sqrt{n*p*(1-p)}\\s=\sqrt{8*0.65*(1-0.65)}\\s=\sqrt{1.82}=1.35$

The expected value out of a 8 people sample is

$\bar{x}=p*n=0.65*8=5.2\\$

Then, our interval of usual values lies between

$\bar{x}- 3s\leq x \leq \bar{x} +3s\\\\5.20-3*1.35\leq x \leq 5.20+3*1.35\\1.15\leq x \leq 9.25$

We can conclude that 0 and 1 (the results that lie outside of the interval) are unusual.
