Step-by-step explanation:
A table titled hours spent studying has entries 4, 5, 9, 15, 8, 2, 20, 1, 6, 9, 10, 8, 10, 8, 1, 2.
Sauron [17]
The range is the maximum value minus the minimum value. In this case would be 20 - 1 which is 19.
<u>Part 1</u>
<u />
denotes the union of the two sets (in other words, all the elements in both sets).
This means it is 
<u>Part 2</u>
<u />
denotes the elements shared between both sets.
This means the answer is ![(4, 7]](https://tex.z-dn.net/?f=%284%2C%207%5D)
To solve the trigonometric expression we proceed as follows;
7(tan x)^3-21tanx=0
this can be written as:
7(tan x)^3=21tanx
dividing through by 7 we get:
(tan x)^3=tan x
dividing through by tan x we get:
(tanx)^1=1
hence;
tan x=+\-1
when tan x=1
x=45
when tan x=-1
x=-45
Given that our answer should be at the interval [0,2π] the answer:
45=45/180=1/4π
