- Sharmeen wants to find the least crowded time to visit the skating rink. She records
the temperature outside and the number of
skaters at the rink at that time. She makes a
scatter plot of the data. She labels one axis
"Number of Skaters." Which data should be on
the other axis?
(А)
time of day
(В)
number of skaters
temperature outside
D
location of the rink

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 ☺

answer: the answer is   graph (a)

same question do you know the answer

answer: the answer to this problem is yes because 4n + 4 does equal 2m - 6

step-by-step explanation: first you have to calculate 2m - 6 second you have to calculate 4n + 4 finally you have to get your answer
