Kelly went on vacation to the Hamptons. She was curious about whether rich people own a lot of TVs, so she went door to door in 333 neighborhoods, asking people how many TVs they owned. Here's what she found: The inventor of the flat-screen TV lived in neighborhood AAA. He owned 787878 TVs. Every home in neighborhood BBB owned 333 TVs . TV ownership in neighborhood CCC was normally distributed with a median of 666 TVs. Which of the following is true? Choose all answers that apply: Choose all answers that apply: (Choice A) A The standard deviation for number of TVs in neighborhood BBB is abnormally low. (Choice B) B The interquartile range for TVs in neighborhood AAA is almost certainly the highest interquartile range among the 333 neighborhoods. (Choice C) C The mean number of TVs in neighborhood CCC is about twice as large as the mean number of TVs in neighborhood BBB. (Choice D) D The interquartile range and the standard deviation for number of TVs in neighborhood BBB are equal.

step-by-step explanation: so we look at the formula un = a + (n-1)d

un is the amount of seats

n is the nth term aka row number

a is the original sequence/row number

d is the difference between each term

so in this a=22 d=6 and n can remain as n because we are simply formjng a rule

lets put these in the equation

un=22+(n-1)(6)

this is your answer to part a

however

lets double check that this is correct, we'll try putting it into the second term

un=a+(n-1)d

u2=22+(2-1)(6)

u2=22+6

u2=28

as the question said the second row has 28 seats so now we know the formula we made is correct.

as for part b

un=a+(n-1)

its asking us to find a row with 100 seats.

remember un was the amount of seata so all we do is substitute this in.

un=100 a=22 d=6

un=a+(n-1)d

100=22+(n-1)(6)

so now we simplify to find n which is the row number.

100-22=22+(n-1)(6)-22

78=(n-1)(6)

78/6=(n-1)(6)/6

13=n-1

13+1=n-1+1

14=n

so now we know that in the 14th row there is 100 seats.

hope this and that you understood! its my first time using the app or anyone out on here : p its also me to revise so a bunch! ask more questions if you dont understand ☺
