Answer:

Option 4

Step-by-step explanation:

Group B, because seven children have a forearm length longer than 10 inches.

Additional verification :

Finding average forearm length of Group A :

  • 9(3) + 10(5) + 11(2) / 10
  • 27 + 50 + 22 / 10
  • 99/10
  • 9.9

Finding average forearm length of Group B :

  • 10(3) + 11(4) + 12(3) / 10
  • 30 + 44 + 36 / 10
  • 100/10
  • 10

Group B clearly has the longer forearm length.

What would the answer to this question be? show work please
AURORKA [14]

Answer:

B

Step-by-step explanation:

The volume of a rectangular prism is the length times width times height.

V = LWH

V = (4√3)(3√6)W

V = 12√18 W

V = 36√2 W

If the volume is irrational, then W cannot have a radical that is half of a perfect square, because when multiplied by √2, that would yield a rational volume.  For example, √18 × √2 = √36 = 6.

Therefore, the answer must be B, because 12 is not half of a perfect square.

V = 36√2 (4√12)

V = 144√24

V = 288√6

Someone please help me on number 30. Thank you
timurjin [86]

8.9-3.3j=-2.2j+2.3
add 3.3j to both sides
8.9=1.1j+2.3
subtract 2.3 from both sides
6.6=1.1j
divide both sides by 1.1
6=j
