Step-by-step explanation:
 start by setting each equation to each other

first we are going to subtract 2x from both side of the equation

now subtract 1 from both sides 

now divide by -3 on both sides
 
        
             
        
        
        
Answer:
sinC=56/72
Step-by-step explanation: I cant explain it but it’correct
 
        
             
        
        
        
15 * 15 * 15 * 500 = 1,687,500. it's different from finding 45 * 500 because 
15 * 15* 15 * 500 is the same as writing it as 15^3 * 500. This meaning you multiply the number 15 by itself 3 times, not add it 3 times, which is what
 45 * 500 was showing. I hope this helped.

Answer:
Null hypothesis: ∪ =  No possible child abuse or neglect
Alternative hypothesis: Uₐ = Possible child abuse or neglect
Step-by-step explanation:
Null hypothesis: ∪ =  No possible child abuse or neglect
Alternative hypothesis: Uₐ = Possible child abuse or neglect
A type I error occurs when you reject the null hypothesis when it is true. In this situation, a type I error occurs when you conclude on possible child neglect or abuse and place the child in protective custody
A type II error occurs when you accept the null hypothesis when it is false. In this instance, a type II error occurs when you conclude on no possible child abuse or neglect when there is and fail to remove the child from the home.
In this case, the type II error is the more serious error. Failure to remove the child when there is possible child abuse or neglect will lead to more detrimental effect. Although, the type I error is also serious, it is not so detrimental as the type II error.
