A study looked at the running times of certain movies released in​ 2005, as shown to the right. The standard deviation of these running times is 18.4 ​minutes, and the quartiles are Upper Q 1 equals99 minutes and Upper Q 3 equals118 minutes. ​a) Describe the spread in running times based on ​i) the quartiles. ​ii) the standard deviation. ​b) Should there be any concerns about using either of these descriptions of​ spread? Explain.

step-by-step explanation:

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.
