Answer:
3 mph
Step-by-step explanation:
So the average speed is simply: . In case, the total time is 25 minutes + 55 minutes which is a total of 80 minutes, or 1.33 hours. The total distance traveled is two miles + two miles, since he jogged two miles to the park, and then he turns around and walks the same path. So in total he traveled 4 miles. Plugging this in to the formula gives you the equation:
Answer:
45

36 times 25 =900 from then keep adding 36 and count the times you add 36 and it comes out as 45 i believe tell me if I'm wrong
How much work is done in an hour by each:
s = 1/6 of the yard in one hourb = 1/10 of the yard in an hour
working together they can do:
1/6 + 1/10 in an hour; or 16/60; we can invert this number to determine how long it takes to finish the yard
60/16 hours
=3 hours and 45 minutes
The t-test for the two means is appropriate in this situation because women and men are independent samples.
<h3>What are Independent Samples?</h3>
Independent samples are those that are chosen at random, ensuring that their results are independent of other observations' values.
The premise that samples are independent underlies many statistical analyses. Others are made to evaluate non-independent sample sets.
The Independent Samples t-Test analyzes the means of two separate groups to see if there is statistical support that the population mean values are statistically substantially different. A parametric test is the Independent Samples t-Test.
