Answer:
mean = 9.3
median = 10
mode =13
Step-by-step explanation:
First put the data in order from smallest to largest
1,1,7,9,9,10,11,13,13,13,15
The mean is the sum of all the numbers divide by how many numbers we have
(1+1+7+9+9+10+11+13+13+13+15)/11102/11=9.272727=9.3
median is the middle number
11/2 = 5.5
The sixth number is the median= 10
mode is most often 13 appears the most
[(100-15)/100 * $3]
= $2.55
$5.35 - $2.55
= $2.80 |80% paper|
80/100 = 2.80/x
4/5 = 2.80/x
4x = 14
x = 3.5
Original price of the paper = $3.50
If m ACD = 30 => m DCB = 60.
In triangle ACD:
AC^{2}+CB^{2}=AB^{2} => AB=
=32.
=> P=16+32+
=48 +

Answer:
In solid geometry, a face is a flat (planar) surface that forms part of the boundary of a solid object; a three-dimensional solid bounded exclusively by faces is a polyhedron. (OR) A face is a 2D shape that makes up one surface of a 3D shape, an edge is where two faces meet and a vertex is the point or corner of a geometric shape.
