Step-by-step explanation:
Mean= The data points that add up, or, the sum of all data points, divided by the number of data points, will give you the answer,
So
20+50+30+40+60+80 would be
100+40+60+80 which is
200.
Since there are 6 numbers in the problem, we do
200/6
which will give us
33.33 etc. (33.3333333333 on and on forever)

Answer:
Quedan 153 sillas
Step-by-step explanation:
Primero sabemos que en una sala de teatro tenían 7 filas, y en cada una de esas filas habían 23 sillas.
Entonces, originalmente, el número total de sillas es 7 veces 23:
S = 7*23 = 161
Luego sabemos que quitan 8 de esas sillas, entonces el número de sillas que quedan es la diferencia entre el número original de sillas, 161, y 8, que nos da:
S = 161 - 8 = 153
Quedan 153 sillas

Hey there, Ashytyn!
Area of a triangle, any triangle, is defined as base times height divided by two.
Why?
Think about if this right triangle was a rectangle. You'd multiply the four times the two for the area, right? Now we first have to realize that this triangle is half of a rectangle, and <em>that's why</em> we divide by two.
Therefore, we have:
A =
A = 2(4)/2
A = 8/2
A = 4 units squared.
Hope this helps!
