Answer:
Step-by-step explanation:
Part A.
Expression
= 10
Because 100 =
and ![[(10)^2]^{\frac{1}{2}}=10^1=10](https://tex.z-dn.net/?f=%5B%2810%29%5E2%5D%5E%7B%5Cfrac%7B1%7D%7B2%7D%7D%3D10%5E1%3D10)
[Since,
]
Part B.
When simplified, the answer is RATIONAL.
[Since, 10 can be written as
]
Answer:
The smaller the MAD the less variability, meaning a bigger MAD means more distance between data.
Step-by-step explanation:
<span>To begin you have to find the midpoint of the side with (2,4) and (-4,2) as vertexes.
[ 2 + -4 ] / 2, [ 2 + 4 ] / 2 ) = (-1, 3)
Then you have to find the point 2/3 of the distance from (0,-2) to (-1,3) =
(0 + (-1 - 0) (2/3) , -2 + ( 3 - -2)(2/3) )
( 0 - 2/3, -2 + (5)(2/3) )
(-2/3, -2 +10/3 )
The coordinates of the centriod of a triangle are (-2/3 , 4/3 )</span>
