Ms. Li gave her students a quiz that was supposed to take 6 minutes to complete. She asked her students to record the amount of time, to the nearest minute, that it took them to
complete the quiz. Ms. Li wants to create a data display that will summarize the data and
show how many students took 6 minutes to complete the quiz. Which data display should
she create?
a dot plot
a histogram with intervals 1-3, 4-6, 7-9, and
10-12
a box plot
a histogram with intervals 1-4, 5-8, and 9-12
8395 complete

it will be a cylinder. with a diameter of 8 and 4 single pieces high

step-by-step explanation:

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

3x + 4y -25 =0 represents the amount of change sianna should recieve
