Answer: Not unusual.
Step-by-step explanation:
We know that the z-scores lower than -1.96 or higher than 1.96 are considered as unusual.
Given : Sample size : n= 65
Sample mean = 
Standard deviation : 
Formula for z-score : 
At x= 213
Since , -1.96< 0.17 <1.96
It means the probability of a sample mean being greater than 213 is not unusual.
Find the area and perimeter of the following triangle with the given vertices:
(1, 2), (8, 2) and (3, 6)
Explain your reasoning; show all your work for full credit!
When two triangles are congruent they will have exactly the same three sides and exactly the same three angles. The equal sides and angles may not be in the same position (if there is a turn or a flip), but they are there.
