Answer:
It is not normally distributed as it has it main concentration in only one side.
Step-by-step explanation:
So, we are given that the class width is equal to 0.2. Thus we will have that the first class is 0.00 - 0.20, second class is 0.20 - 0.40 and so on(that is 0.2 difference). 
So, let us begin the groupings into their different classes, shall we? 
Data given:
0.31 0.31 0 0 0 0.19 0.19 0 0.150.15 0 0.01 0.01 0.19 0.19 0.53 0.53 0 0.
(1). 0.00 - 0.20: there are 15 values that falls into this category. That is 0 0 0 0.19 0.19 0 0.15 0.15 0 0.01 0.01 0.19 0.19 0 0. 
(2). 0.20 - 0.40: there are 2 values that falls into this category. That is 0.31 0.31
(3). 0.4 - 0.6 : there are 2 values that falls into this category.
(4). 0.6 - 0.8: there 0 values that falls into this category. That is 0.53 0.53.
Class interval            frequency.
0.00 - 0.20.                   15.
0.20 - 0.40.                    2.
0.4 - 0.6.                        2.
 
        
             
        
        
        
Answer:
To find volume of a tent this would be your formula: 
start by taking the base of the triangle on your tent typically located in the front
1/2 (height) (width) to get your area (DONT SKIP THIS STEP)
Then take your area you just calculated and do 
(area) (length) 
Let me give you an example:
in the picture below
height: 3 cm
length: 8 cm
Width: 12 cm 
Next do your first formula:
1/2 (3)(12)= 18 cm
(Calculation of one face)
then your second:
(18)(8)= 144 
Hopefully this guide helped you sorry i couldn't answer your question without a picture!
 
        
             
        
        
        
Hey there!
In this scenario, we are given the area of the rug. It is asking for the diameter, the distance across the rug. The area is the radius (half of diameter) squared times pi (we will use 3.14). 
First, we need to undo the area and find the radius.
78.5/3.14=25
√25=5
Since the diameter is twice the radius, we multiply or radius by two.
5*2=10
Therefore, our edge is 10 feet from one edge to the other.
I hope this helps!
 
        
             
        
        
        
Answer:
x < 12
Step-by-step explanation:
So 8 times the sum of a number and 26 is less than 304. To find the number, lets write a equation where the "number" is x. 
8 times the sum of a number and 26 can be written as 8 * x+26, however since the sum of x and 26 are being multiplied, we write this as 8(x+26). Since 8 times the sum of a number and 26 is less than 304, we set 8(x+26) to < 304. This gives us our equation:
8(x+26) < 304
Lets start to solve for x by dividing by 8, giving us:
x+26 < 38
Now lets isolate x by subtracting 26 from both sides, which gives us our answer:
x < 12 
So x is less than 12.
Hope this helps!
