Abaker measured the length of different loaves of bread. the interquartile range of a data set was 12 inches. which statement is also true for the data set? a) the middle 50% of the loaves are 12 inches long. b) most of the loaves are at least 12 inches long. c) the distance between the 25th and 75th percentile is 12 inches. d) the distance between the 25th and 50th percentile is 12 inches.

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

answer: 270

step-by-step explanation:

you have to times 200 by 1.35 to get your answer
