Answer:
3/26 students or 11%
Step-by-step explanation:
probability dependant formula:P(A∪B)=P(A)+P(B)−P(A∩B)
P(a)= basketball
P(b)=baseball
so
P(AUB)=P(A)+P(B)-P(A∩B)= 18/26+5/26-20/26=3/26
3/26 or 11%
OR you could solve this by adding all the sport/non sport #'s 18+5+6=29 and subtract 26 from 29
29-26=3
hence 3/26 students would randomly play basketball or baseball
Hope this Helps!
Answer:
z=20.8
x=16.97
y=12
Step-by-step explanation:
The triangle on the right is a 30,60,90 triangle, a special right triangle with simple rules to find the side lengths. sides A,B, and C where C is the hypotenuse (24 in your diagram). The short side A is= 1/2 of side C (12 in your diagram). The long side B is= side A*√3 (20.8 in your diagram).
The triangle on the left is another special right triangle called a 45,45,90. The rules for this triangle are C= A*√2, and B=A. Because of the rules in the 30,60,90 triangle, we know that side A is 12. This means that side B (y)=12. Side C (x)= 16.97.
Hope this helped! Sorry if my explanation is confusing, but the rules for special right triangles can be easily found online and then calculated :)
Answer:
The total surface area is
57ft^2.
The area would be 24 in. because to find the area of a triangle you need to multiply the height by the base then divide it by 2 and you get your answer.
6*8=48
48/2=24
Hope this helps.
