Answer:

The average speed for the whole rally is <u>45 miles per hour</u>.

Step-by-step explanation:

Given:

You have traveled 30 miles east and then 30 miles north. To get back to the start, I travel 30 miles west in 1 hour and then 30 miles south in a half hour.

Now, to find the average speed for the whole rally.

So, for getting the speed of 30 miles west in 1 hour.

By putting formula:

Speed = \frac{distance}{time}

Speed = \frac{30}{1}

Speed = 30\ miles\ per\ hour

Now, to get the speed of 30 miles south in half hour same way as above:

Speed=\frac{30}{0.5}

Speed = 60\ miles\ per\ hour

Then, to get the average speed.

We calculate the average of both the speed:

Average=\frac{30+60}{2}

Average=\frac{90}{2}

Average=45 miles\ per\ hour.

Therefore, the average speed for the whole rally is 45 miles per hour.

Assume that there are 2 trials.
vampirchik [111]
Answer: The p(success) = 0.6

Your question is a little unclear, but I believe you are asking about the probability that at least one of the trials in the experiment were successful.

If that is the case, you simply have to add the probability of 1 success with the probability of 2 successes.

That is 0.48 +  0.16 = 0.64

Rounding our answer to one decimal place gives us 0.6.

nignag [31]
To be pefectly honest, your question really doesn't make sense.
160 is a rational number, and there isn't any irrational number that's
related, connected, or tied to it in any particular way.
