When solving negative one over five -1/5 (x − 25) = 7, what is the correct sequence of operations
aleksandr82 [10.1K]

The solution would be like this for this specific problem:

 

\left( { - 5} \right)&#10;\cdot \left( { - \frac{1}{5}} \right) \cdot \left( {x - 25} \right) = 7 \cdot&#10;\left( { - 5} \right)

 

 

\left( { - 5} \right)&#10;\cdot \left( { - \frac{1}{5}} \right) = 1

 

The correct sequence of operations when solving negative one over five (x − 25) = 7 would be multiply each side by −5, and adding 25 to each side.

STatiana [176]

Answer:  False

Step-by-step explanation:

We know that , If p-value < \alpha , we reject the null hypothesis .

If p-value ≥ \alpha , we are fail to reject the null hypothesis .

As per given , we have

The p value for an independent samples t-test is 0.043.

The level of significance is \alpha=0.05

Since , 0.043 < 0.05.

i.e. p-value <  \alpha

It means  we reject the null hypothesis .

It means the null hypothesis is false.

Hence , the correct decision in this scenario is to favor the null hypothesis : False
