Answer: The percentage of students signed up for neither canoeing nor trekking m=32%
Step-by-step explanation:
Given: The total number of students in summer camp n(S)=120
Number of students signed up for canoeing n(C)=72
Number of students signed up for trekking m(T)= 23
Number students signed up for trekking and canoeing n(C∩T)=13
Number of students signed up for only canoeing (Not trekking)=
Number of students signed up for only trekking (Not canoeing)=
Now, the number of students signed up for either trekking or canoeing is given by :-
Number of students signed up for neither trekking nor canoeing is given by :-

Answer:
an isosceles right triangle
Step-by-step explanation:
The square of the length of a side can be found from the distance formula:
d^2 = (x2-x1)^2 +(y2-y1)^2
The square of the length of WX is ...
WX^2 = (-3-(-10))^2 +(-1-4)^2 = 49+25 = 74
The square of the length of XY is ...
XY^2 = (-5-(-3))^2 +(11-(-1))^2 = 4 +144 = 148
The square of the length of YW is ...
YW^2 = (-10-(-5))^2 +(4 -11)^2 = 25 +49 = 74
The sum of the squares of the short sides is equal to the square of the long side, so this is a right triangle. The squares of the short sides are equal, so this is an isosceles right triangle.
