Which is a solution of the inequality 5≤−4x−65≤−4x−6?

1 answer:

4 0

Step 1: Add 65 to all sides

Step 2: Add 4x to all sides

Step 3: subtract 70 to all sides

Step 4: divide by 4 to all sides

Ending: x is greater than or equal to -17.5

You will end up with it saying -17.5 is greater than or equal to -2.75 but since -17.5 is not greater than -2.75 the answer to this problem is ...

No solution because the inequality that you end up with won't make sense and therefore does not work in the problem

Answer: NO SOLUTION (yayayyayay).

OleMash [197]

Answer:

Step-by-step explanation:

Arrange data set

19, 4, 17, 3, 6, 5,5, 3, 11, 12, 3, 7, 15, 8, 8, 10,5, 3, 12, 41, 36

in ascending order

3, 3, 3, 3, 4, 5, 5, 5, 6, 7, 8, 8, 10, 11, 12, 12, 15, 17, 19, 36, 41

The median is $Q_2=8$

$Q_1=\dfrac{4+5}{2}=4.5$

$Q_3=\dfrac{12+15}{2}=13.5$

Thus, the interquartile range is

$Q_3-Q_1=13.5-4.5=9$
