Answer:
Descriptive statistics
Explanation:
The population average is a descriptive statistic. It informs about how the population looks like, in this case, the population looks like having a average of 1000.
If, using her class's average where to infer the population average that is inferential statistic. But that is not the case
Step-by-step answer:
This is a regular heptagon, means it has 7 <em>congruent</em> sides and 7 <em>congruent </em>vertex angles.
To work with polygons, there is a very important piece of information that you must know to solve the majority of related problems.
This is:
sum of exterior angles of polygons = 360 degrees.
If you don't remember the 360 degrees, think of the sum of exterior angles of an equilateral triangle, which is 3*(180-60)=3*120=360! It works!
For a regular heptagon, c = 360/7=51.43 degrees approx.
This means that each vertex angle measures
vertex angle = 180-c
So since 2d+the vertex angle = 360, we have
2d+(180-c)=360
solve for d:
2d=360-(180-c)=180+c
d=(180+c)/2=90+c/2=115.71 degrees. (approx.)

Step-by-step explanation:
Answer:
Let's solve for f.
fx=
4x−3
x−10
Step 1: Multiply both sides by x-10.
fx2−10fx=4x−3
Step 2: Factor out variable f.
f(x2−10x)=4x−3
Step 3: Divide both sides by x^2-10x.
f(x2−10x)
x2−10x
=
4x−3
x2−10x
f=
4x−3
x2−10x
Answer:
f=
4x−3
x2−10x
Let's solve for g.
gx=
2x−8
x−10
Step 1: Multiply both sides by x-10.
gx2−10gx=2x−8
Step 2: Factor out variable g.
g(x2−10x)=2x−8
Step 3: Divide both sides by x^2-10x.
g(x2−10x)
x2−10x
=
2x−8
x2−10x
g=
2x−8
x2−10x
Answer:
g=
