Step-by-step explanation:
The main difference between an ogive and a frequency polygon is - An ogive is a plot of cumulative values while a frequency polygon is a plot of the values themselves. An ogive is also called the cumulative frequency graph. It is a curve which shows the cumulative frequency of a given set of data.
< 1 and < 2......adjacent angles...because they have a common side and a comon vertex
< 1 and < 2.....complimentary angles....because when added, they equal 90
Answer:
14 > 12
Step-by-step explanation:
2(3b+7) - 6b > 12
6b + 14 - 6b > 12
14 > 12

Answer:
- r + t = 25
- 2r +4t = 92
- 4 T-Rex, 21 triceratops
Step-by-step explanation:
For this we have to assume that the T-Rex has only 2 legs. Let r represent the number of T-Rex, and t represent the number of triceratops. The problem statement tells of two relationships:
r + t = 25 . . . . . . total number of dinosaurs in the exhibit
2r +4t = 92 . . . . total number of legs in the exhibit
__
Multiplying the second equation by 1/2 and subtracting the first, we find ...
(1/2)(2r +4t) -(r +t) = 1/2(92) -(25)
t = 21 . . . . . . simplify
r = 25 -21 = 4
There are 4 T-Rex, and 21 triceratops.
