Answer:
Yes
Step-by-step explanation:
The z-score corresponding to a number or score can be calculated using:
Where x stands for the individual scores, and
stands for the mean.
Since
for all numbers or scores below the mean, the difference will always be negative these values below the mean.
This will always result in a negative z-score for all numbers below the mean.
Given:
The coordinates of point A are (7,4).
It is dilated from the origin by a scale factor r = 3.
To find:
The coordinates of A'.
Solution:
If a figure is dilated from the origin by a scale factor k, then
Here, the figure is dilated from the origin by a scale factor 3, so the rule of dilation is given by:
Using this rule, we get
Therefore, the coordinates of point A' are (21,12).
Answer:
C.
Step-by-step explanation:
Width = x
Length = one fifth of width minus 2
Length =
Perimeter is given by the formula
