You could add up all the relative frequencies to make sure that you have 100% accounted for.
The relative frequency is the percent out of 100% for a particular item. If you have found the relative frequency for all items, it should equal 100%.
To find the zeros set the factors on the numerator equal to zero and solve
(x - 1) = 0 x = 1
(x + 1) = 0 x = -1
Answer:
Answer:
8
Step-by-step explanation:
x= centesimal angle (100 degrees in a
right angle)
y= sexagesimal angle (90 degrees in a
right angle)
=
x - y = 15
xx90/100 = y
xx9/10 = y
X - XX9/10 = 15
10x/10 - 9x/10 = 15
=
X/10 = 15
x= 150
y = 150x9/10 = 15x9 = 135
=
using centesimal system:
the sum of all external angles in a
polygon is 400 degrees (a full circle).
one external angle is the complement
of one internal angle to 200 degrees =
200-150=50 degrees.
to find the number of sides of the
polygon we need to find the number of
angles or corners. and that is how many
external angles fit into the full circle.
n = 400/50 = 8
=
the polygon has 8 sides
It should be 132, area of parallelogram is same as rectangle actually, it just tilted a bit, so is 11 x 12
Answer:
D Scalene triangle
Step-by-step explanation:
All angles are different, there the sides of triangle will be different which is a Scalene triangle
