Answer:
I would say parallelogram. So the rectangle still fits but more shapes can be applied.
Answer: b. 30%
Step-by-step explanation:
- A measure of relative variability is known as coefficient of variation. It is the ratio of the standard deviation to the mean.
i.e. 
Given: mean = 
Variance = 
Now, 
in percent , 
Hence, correct option is b. 30%.
y=2x so replacr the -y with -2x so 2x+6 is 8x. :)
Answer:
It will be 120°
It because if you matched those two points you will have two angles of 90° degree inside that square and in the triangle at the above 120-90= 30 degrees for both angles and since that all angles of the triangle are equal 180 then 180-(30+30)=120°.
Sorry if my explanation isn't that good.
density= mass/volume
mass= densiy x volume
mass= 6.3 g/mm^3 x 30mm^3= 189 g
