second-period class average:
55+70+450+480+170+270+95 = 1590
1590/20 = 79.5
sixth-period class average:
65+225+480+595+270+190 = 1825
1825/20 = 91.25
on average, students in the sixth period class scored higher
let's set up an equation
4x=24
solve normally:
x=6
so the expression is 4x=24 and she can have 6 kids in each group
The table of values of the function y = ∛x is
x y
-8 -2
-1 -1
0 0
1 1
8 2
<h3>How to fill in the y values?</h3>
The function is given as:
y = ∛x
When x = -8, we have:
y = ∛-8 = -2
When x = -1, we have:
y = ∛-1 = -1
When x = 0, we have:
y = ∛0 = 0
When x = 1, we have:
y = ∛1 = 1
When x = 8, we have:
y = ∛8 = 8
So, the table of values is
x y
-8 -2
-1 -1
0 0
1 1
8 2

65 because if you put all the numbers in order and work out which one is in the middle you get the median. i enjoy using the rhyme. Hey diddle diddle, the medians the middle, you add then divide for the mean, the mode is the one that you see the most and the range is the difference between.
16x²=(4x)², 9=3², 24x=2*4x*3
so this is a perfect square: (4x+3)²
