Find the range and interquartile range of the data. round to the nearest tenth. 183, 339, 284, 111, 134, 344, 133 a. range=211; interquartile range= 206 b. range=233; interquartile range= 206 c. range= 233; interquartile range= 156 d. range= 211; interquartile range= 156

We first need to list the following Data Set:

111, 133, 134, 183, 284, 334, 339

Range = highest value - lowest value =

Range = 339 - 111 = 228

Interquartile range = upper quartile - lower quartile =

(or IQR = interquartile range, another term)

Interquartile range = 334 - 133 = 201

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

6e14 is the answer.
