The IQR of the first period is 15. The IQR of the third period is 1/3 that, 5*(1/3) is equal to 5.

For the third period, Q1 is 78. The expression for Q3 is Q1+IQR

Therefore, 78+5 = 83

Q3 of the third period is 83

d1i1m1o1n [39]

Answer:

# yellow = 20

# blue = 23

# red = 5

Step-by-step explanation:

let 'r' = # red marbles

let '4r' = # yellow marbles

let '3+4r' = # blue marbles

r + 4r + 3 + 4r = 48

9r + 3 = 48

9r = 45

r = 5

red = 5

yellow = 4(5) = 20

blue = 3+4(5) = 23

Rita has the following data:
Lubov Fominskaja [6]
The range is the difference between the largest number and the smallest number. This means you subtract the smallest number from the largest number. If the range is 8, then you can add 8 to the smallest number on the list to get the largest number, m.
Our smallest number is 12, so add 8 to 12.
8 + 12 = 20, so m is 20.
I hope this helps!
