Answer:
6x-7
Step-by-step explanation:
The data are bunched towards the higher values above the mean, but spread out to values below the mean. Therefore the median provides a better description of the center.
Answer:
The perimeter is 56mm
Step-by-step explanation:
N/B: the figure is not given, nevertheless we can infer that the figure is a triangular figure given that the lengths provided is just three.
So the perimeter is the distance around the object.
Perimeter =20+20+16= 56mm
Let x be the first angle
y be the second angle
z be the third angle.
for the second angle, complementary angles are angles sum are 90 degrees
y = 2 ( 90 - x )
y = 180 - 2x
2x + y = 180
for the third angle, supplementary angles are angles sum are 180 degrees
z = 0.5( 180 - x )
z = 90 - 0.5x
0.5x + z = 90
then the sum of a triangle is 180
x + y + z = 180
so x = 60
y = 60
z = 60
