6. a foresting service conducted a survey to see if tree farms that planted hardwood trees were more profitable over a 30-year period than tree farms that planted softwood trees. the results of this study showed that hardwood trees had a 46% higher profit per acre. are the results statistically significant?
no, because planting softwood trees have a higher profit per acre.
no, because there is not enough information given to make a conclusion.
yes, because the chance of getting a similar result is small.
yes, because planting hardwood trees have a higher profit per acre.

Yes because planting hardwood trees have a higher profit per acre.

Step-by-step explanation:

step-by-step explanation:

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.
