Mary drew a box and whisker plot for the following data: 23, 10, 12, 30, 26, 8, 25, 18.Find the following: First Quartile: Median: Third Quartile: Range:

1st  Qtrl:  11

Median:  20.5

3rd Qtrl:  25.5

Range:  22

Step-by-step explanation:

Median = average of 2 middle values (18 + 23) / 2

1st Qtrl = average of 10 and 12 (the lower half of data)

3rd Qtrl = average of 25 and 26 (the upper half of data)

Range = largest value - smallest value;  30 - 8 = 22

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.
