Answer:

Median = 6
IQR = 3

Step-by-step explanation:

Given data:

8, 5, 6, 6, 4, 9, 7, 6, 5, 9

Put this into ascending order:

4, 5, 5, 6, 6, 6, 7, 8, 9, 9

Median is 6 as both middle numbers are same = 6

Split the data into lower and upper halves:

(4, 5, 5, 6, 6)(6, 7, 8, 9, 9)

Q1 is the median of the lower half:

Q1 = 5

Q3 is the median of the upper half:

Q3 = 8

IQR is the difference of Q3 and Q1

IQR = 8 - 5 = 3

Liula [17]

Answer:

Step-by-step explanation:

∠ABC= 180° -142° (adj. ∠s on a str. line)

∠ABC= 38°

∠BAC= 180° -133° (adj. ∠s on a str. line)

∠BAC= 47°

∠ACB= 180° -38° -47° (∠ sum of △)

∠ACB= 95°

n°= 180° -95° (adj. ∠s on a str. line)

n°= 85°

n= 85
