1. The members of Photography Club at Manchester High measured their heights and came up with a mathematical way to calculate where to set up their camera angles to best serve the majority of students they would be photographing. Just by measuring the members of the club, they came up with a median height of 5'8" with a standard deviation of 3 inches.

Draw a normal distribution curve (2 point) and be sure to
show your work for your calculations! :)

a. How often (what percent of the time) would students be between 5'5" and 5'11"? (1 point)

b. How often (what percent of the time) would students be between 5'5" and 6'2"? (1 point)

C. If the club measured the heights of 2000 students, how many would be between 5'2 and 6'5" (1 point)

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 ☺
