Answer:

D. Removing the outlier will decrease the spread of the graph of the data set.

Luna mixes 3/4 cup of orange juice with 3/8 cup of cranberry juice. She gives 5/8 cup of the juice to mags. How much is left in
Hunter-Best [27]
3/4 = 4/8 (converting fractions )

4/8 + 3/8 = 9/8 cups of juice altogether

9/8 - 5/8 = 4/8 (taking away mags' amount )

4/8 is equivalent to a 1/2 so she still has 1/2 a cup of juice left.

What is 3(2x-4)=5x+2
otez555 [7]
First we distribute 3 into 2x and -4.

3 x 2x = 6x
3 x -4 = -12

That will make the left side of the equation:

6x - 12 = 5x + 2

Now we subtract 5x on both sides of the equation.

x - 12 = 2

Finally we add 12 on both sides of the equation.

x = 14 is the answer
