hope it helps!!
ANSWER

EXPLANATION
From the graph, the coordinates of Y are:

We want to find the image of this point after a dilation by a scale factor of -½ about the origin.
The rule for the dilation is :

To find the coordinates of Y', we plug the coordinates of Y.


The first choice is correct.
Answer:
n= s/180 +2
Step-by-step explanation:
s=(n-2)180
/180
s/180=n-2
+2
s/180 +2 =n
Answer:
0.09 average effect
Step-by-step explanation:
Given that the t statistics = 1.54
Sample size (n) = 25
Therefore, variance = t²/n
Variance = 1.54²/25
Variance = 2.372/25
Variance = 0.09
