We are given the coordinate of the 3 vertices. From these coordinates we can find the length of the sides using the distance formula and the sum of all the sides will be equal to the perimeter of the triangle.
Side PQ =
Side QR =
Side RP =
So, the perimeter of the triangle will be 8 + 4.5 + 7.2 = 19.7
You probably misplaced the digits in option A. The correct answer is 19.7 units.
Answer: Tt is unlikely to have change in the sample mean score is less than 10 points .
Step-by-step explanation:
Given : Mean :
Standard deviation :
Sample size : n= 100
We assume that the change in students scores are normally distributed.
Let X be the random variable that represents the change in students scores .
Z score :
For x = 10
By using the standard normal distribution table , the probability that the change in the sample mean score is less than 10 points :-
Since the calculated probability is less than 0.5.
So , we say that it is unlikely to have change in the sample mean score is less than 10 points .
