Answer:
h=0.344
Step-by-step explanation:
4.52-5h=2.8
Subtract 4.52 from both sides
-5h=-1.72
Divide -5 from both sides
h=0.344
Order set...{160,165,170,240,240,450}
The "mean" is the arithmetic average of the elements...
mean=(160+165+170+240+240+450)/6=237.5
The "median" if the set has an odd number of terms is the middle term, if the set has an even number of terms, it is the average of the middle two terms.
In this case the number of elements is even and the middle two terms are 170 and 240 so:
median=(170+240)/2=205
The "mode" is the term which appears the most in the set, so in this case:
mode=240
The two numbers must add up to 1. 1-0.54=0.46
I need to know what type of quadrilateral it is
40. a) yes, pythagorus' equation says A^2 + B^2 =C^2, If A=3, and B=4, then C would be 5 (the square root of 25 as 9+16=25). 3,4, and 5 are integers/rational so the perimeter would also be rational.
b) yes, if A=3, B=pi, C would be a combination of an irrational number making it irrational as well.
41. This is a special triangle, the sides are 1,2, and sqrt(3) (2 is the hypotenuse). The sqrt(3) is 1.732050808...., it appears to start repeating which means it is rational. Therefore the perimeter would be rational. Use this argument for why it is not irrational.
