Answer:

The function should be 2.5h + 4 = 12

----------------------------------------------------------

Full Question:

Jody has already hiked 4 kilometers. The trail is 12 kilometers long. She can hike 2.5 per hour. Which function will help Jody figure out how many more hours, h, she needs to hike?

Step-by-step explanation:

Let number of hours = h  

Given that she can hike 2.5 per hour. So that means distance travelled in "h" hours will be 2.5h  

It is also given that Jody has already hiked 4 kilometers.  

So total distance travelled by Jody in "h" hours will be (2.5h + 4)  

Given that trail is 12 kilometers long.  

That means Jody has to travel for 12 kilometers. In that case both values will be equal and we get equation:  

2.5h + 4 = 12

Answer:

The answer to your question is: 2, 4, 5, 1 , 3

Step-by-step explanation:

The first line is the second

                                             (3x² - 6)² - (3x²)² = 36(1 - x)(1 + 1)

The second line is the forth

                                             9x⁴ - 36x² + 36x² - 9x⁴ = 36(1 - x)(1 + x)

The next line is the fifth

                                             36 - 36x² = 36(1 - x)(1 + x)

The next line is the first

                                             36(1 - x²) = 36(1 - x)(1 + x)

The last line is the third

                                             36(1 - x)(1 + x) = 36(1 - x)(1 + x)

Natalka [10]

Answer:

There is not sufficient evidence to support the claim μ > 54.4.

Step-by-step explanation:

1) Previous concepts

A hypothesis is defined as "a speculation or theory based on insufficient evidence that lends itself to further testing and experimentation. With further testing, a hypothesis can usually be proven true or false".  

The null hypothesis is defined as "a hypothesis that says there is no statistical significance between the two variables in the hypothesis. It is the hypothesis that the researcher is trying to disprove".

The alternative hypothesis is "just the inverse, or opposite, of the null hypothesis. It is the hypothesis that researcher is trying to prove".

2) Solution to the problem

On this case we want to test is \mu>54.4 and the system of hypothesi on this case are:

Null Hypothesis: \mu \leq 54.4

Alternative hypothesis:\mu >54.4

On this case is our decision is FAILS to reject the null hypothesis then we can conclude that we don't have enough evidence to support the claim at the significance level provided.  So the correct conclusion would be:

There is not sufficient evidence to support the claim μ > 54.4.
