Answer:

Upstream = 0.5 hour.

Downstream = 0.366 hour.

Step-by-step explanation:

Speed of fram in still water (u) = 2.6 mph.

Speed of water (v) = 0.4 mph .

<h3>Time taken by fran to swim 1.1 mi upstream.</h3>

Speed upstream = u - v = (2.6 - 0.4)  mph = 2.2 mph

So the time taken = \frac{distance}{speed}  = \frac{1.1}{2.2} = 0.5 hour.

<h3>Time taken by fran to swim 1.1 mi downstream.</h3>

Speed downstream = u + v = (2.6 + 0.4) mph = 3 mph .

So the time taken = \frac{1.1}{3} =  0.366 hour .

slava [35]

So to rewrite it so that we can find the side, we just need to isolate the a variable.


SA=6a^2


So firstly, divide by 6 on both sides of the equation: \frac{SA}{6} =a^2


Next, square root each side, and your answer should be \sqrt{\frac{SA}{6}} =a

Harman [31]

People often draw hypothesis in research.  Based on executing the test in Question 5, We reject the null hypothesis; the mean delivery time is different for every day of the week.

<h3>Why do we reject the null hypothesis?</h3>

Note that if the p-value of an experiment (Like the one above) is less than or found to be equal to the significance level of your test, one can reject the null hypothesis.

By that, we known that the data is in favors the alternative hypothesis. Hence the results gotten by you are statistically significant. If your p-value is found to be greater than your significance level, you then fail to reject the null hypothesis.
