Answer:
Its C or the 3rd option
(9x+2)
Step-by-step explanation:
You have to inverse the equation meaning do everything the opposite so for example, add the 2 to the other side of the equation
289 196 248 379 319 276 198 349
(in order) 196, 198, 248, 276, 289, 319, 349, 379 there are eight numbers.
--------------------------------------------------------------------------------------
196, 198, 248, 276
since the median is between 198 and 248, we must add both numbers together and divide them by two:
(198 + 248) ÷ 2
= 446/2
<h2>
= 223 (first quartile)</h2>
--------------------------------------------------------------------------------------
289, 319, 349, 379
since the median is between 319 and 349, we must add both numbers together and divide them by two:
(319 + 349) ÷ 2
= 668/2
<h2>
= 334 (third quartile)</h2>
--------------------------------------------------------------------------------------
Interquartile range:
<h2>
IQR: 334 - 223 = 111 </h2>
