Answer:
A linear equation has the greatest x power at 1. 
If you see an equation with only x (no x^2 or x^3 or stuff like that), you will know that it is linear. 
 
        
             
        
        
        
Answer:
729 cubic meters
Step-by-step explanation:
Volume of cube is given by side^3
where side is length of the side
Given in the problem 
side is 9 meters as length, width, and height of fort is 9 meters and it is in cube shape .
Thus,
volume of cube = 9^3 = 9*9*9 = 729
Thus, volume of Haley's fort is 729 cubic meters.
 
        
             
        
        
        
Probability that a student will play both is 7/30
Step-by-step explanation:
Total students = 30
No. of students who play basketball = 18
Probability that a student will play basketball = 18/30 
= 3/5
No. of students who play baseball = 9
Probability that a student will play baseball = 9/30
= 3/10
No. of students who play neither sport = 10
Probability that a student will play neither sport = 10/30
= 1/3
To find : 
Probability that a student will play both = p(student will play both) 
No.of students who play sport = 30 - 10
= 20
Out of 20 students 18 play basketball and 9 play baseball. 
So, some students play both the sports. 
No. of students who play both sports = 18 + 9 - 20
= 7
p(student will play both) = 7/30
Probability that a student will play both is 7/30
