a no the program is not stastically signigficant because the results are unlikely to occur by chance
Answer:

Step-by -step explanation:
Solving inequalities is similar to solving equations.

Subtract 10 from both sides.

Divide by 5 from both sides to isolate the x.

Answer:
Ratio =
= 
Step-by-step explanation:
The perfect squares from 1-30 are:
1, 4, 9, 16, 25
Total no. of perfect squares = five =5
Total no. of non perfect squares = 30-5 = 25
Ratio =
= 5 / 25 = 
Sqrt=13 is not possible apply phythagoren theorm
a^2+b^2=c^2
(√2)^2+(3)^3=11
or other way is (3)^2- (√2)^2=7
