What's the greatest thousand you can multiply by 3 to get close to, but not go over, 4,387

the greatest thousand you can multiply by 3 to get close to, but not go over, 4,387 is 1462

Step-by-step explanation:

4387 / 3 = 1462.33333333

you then round it to a whole number and its 1462

then you check your work

1462 x 3 = 4386

Hope this helps! Have an amazing day! (∩^o^)⊃━☆ Bye!

two data sets with the same median will not have the same varaibility

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
