Answer:

Below in bold.

Step-by-step explanation:

First arrange in ascending order:

5 8 9 11 13 15 16 17 17 18 22 23

Median = mean of the middle 2 values = (15+16)/2 = 15.5.

Mean = Sum of all the values / 12 = 174/12 = 14.5.

Interquartile range = upper quartile - lower quartile = 17 - 11 = 6.

Solve Systems by Substitution 2x+5y=-3 x+8y=4 and 2x+y=7 x-2y=-14

ASHA 777 [7]

2x + 5y = -3 ⇒ 2x + 5y = -3
1x + 8y = 4 ⇒ 2x + 16y = 8
 -11y = -11 
 -11 -11
 y = 1
 2x + 5(1) = -3
 2x + 5 = -3
 -5 -5
 2x = -8
 2 2
 x = -4
 (x, y) = (-4, 1)

2x + 1y = 7 ⇒ 2x + 1y = 7
1x - 2y = -14 ⇒ 2x - 4y = -28
 5y = 35
 5 5
 y = 7
 2x + 7 = 7
 -7 -7
 2x = 0
 2 2
 x = 0
 (x, y) = (0, 7)
