Answer:
50 pieces
Step-by-step explanation:
1 decimeter = 0.1 meter
Therefore,
Thus, 50 pieces can be cut.
Answer:
K' (-1,10)
L'(0,4)
M'(2,2)
Step-by-step explanation:
To use the mapping rule, substitute x and y with the original values
The coordinates of K are x=-4, and y=5.
Using the mapping rule, x of K' = -4+3 = -1
Using the mapping rule y of K' = 2x5=10
So K' is at the coordinate (-1,10)
The coordinates of L are x =-3, and y =2.
Using the mapping rule, x of L' = -3+3=0
Using the mapping rule y of L' = 2x2=4
So L' is at the coordinate (0,4)
The coorindates of M are x=-1 and y=1
Using the mapping rule, x of M' = -1+3=2
Using the mapping rule, y of M' = 2x1 = 2
So M' is at the coordinate (2,2).
Answer:
Option B
Both distributions are nearly symmetric, so the mean and the standard deviation are the best measures for comparison.
Step-by-step explanation:
The answer is this is 9*4=36
So 3 times a number is between -18 and 18
between means it cannot be -18 or 18 so
3 times x=3x
x=unknown
3x
< less than
>greater than
if it is between -18 and 18 then the number is >-18 and <18 so
-18<3x and
18>3x
divide both equations by 3
-6<x
6>x
combine
-6<x<6
solution set=(x|-6<x<6)
