Determine whether the statement is true or false. If it is​ false, rewrite it as a true statement. If you decide to reject the n
Tems11 [23]

Answer:

B

Step-by-step explanation:

When testing hypothesis to make a conclusion, you must find sufficient evident to reject the null hypothesis in favor of the alternative hypothesis. The null hypothesis must fail in order to accept the alternative. Failing to reject is not enough information. Since this is the case then options C and D are false statements and cannot be true. Both state that if you reject the null then the alternative is false or can't be supported. The opposite is true. Option A is also false since you cannot accept the null. You can only fail to reject it. If this is true then the alternative certainly cannot be accepted. Option B must be correct and the statement (thought not listed here) must be true.

A. This statement is false. A true statement​ is, "If you decide to accept the null​ hypothesis, then you can support the alternative​ hypothesis."

B. This statement is true.

C. This statement is false. A true statement​ is, "If you decide to reject the null​ hypothesis, then you​ can't support the alternative​ hypothesis."

D. This statement is false. A true statement​ is, "If you decide to reject the null​ hypothesis, then you can assume the alternative hypothesis is​ false."

365x + 125 = 250x + 175
maxonik [38]
First, set up the equation. 
365x + 125 = 250x + 175 

Second, combine like terms on the same side by subtracting 250x and 125 from both sides.

365x +125 = 250x + 175  
-250x  -125   -250x -125 
__________________
115x = 50

Third, divide both sides by 115 to solve for x.

115x = 50
----      ----
115     115 

Fourth, simplify. 

x=50/115=10/23 or 0.435
