Samantha, brooklyn, and mary went to bonnaroo music festival where they each attended various concerts. samantha only went to rock concerts, and the sound level at these concerts was normally distributed between 113 and 117 decibels. brooklyn went to 44 concerts with samantha and also went to 55 folk concerts where the sound level was between 95 and 97 decibels. mary got sick, so she only attended 22 shows − one rock concert and one folk concert. the median sound level of concerts that samantha attended was likely (< ,> , or =) the mean sound level of the concerts she attended. the median sound level of concerts that brooklyn attended was (< ,> , or =) the mean sound level of the concerts she attended. the median sound level of concerts that mary attended was (< ,> , or =) the mean sound level of the concerts she attended.

A.

B.

GCF of 72 and 81,

72 = 2 X 2 X 2 X 3 X 3

81 = 3 X 3 X 3 X 3

GCF = 3 X 3 ( Common terms )

= 9,

Therefore, GCF of 72 and 81 is 9.

C.

Another two factors,

( 72 + 81 ) , 9,

153, 9

153 = 3 X 3 X 17

Here is also common terms ( 3,3 ) ,

Hence 153 and 9 are factors of 72 and 81.
