A box-and-whisker plot. The number line goes from 1 to 15. The whiskers range from 1 to 14, and the box ranges from 6 to 11. A line divides the box at 9.5.
Which statement correctly finds the interquartile range for the set of data represented by the box plot?
14 – 1 = 13
11 – 6 = 5
11 – 1 = 10
6 – 1 = 5

B.) 11-6=5

Step-by-step explanation:

You can find the interquartile range by subtracting the upper quartile by the lower quartile. From the information provided, we can see that 'the box ranges from 6 to 11'. These values are the upper and lower quartile values. The higher positive number is the upper quartile, so:

11-6=5

Finito.

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
