Dean's family has been traveling on the same speed for two days, so to find how far you will need to travel you will need to find how far they are traveling in one hour..

To find this you will need to set up a proportion...

3/195 = 1/x

Solve this proportion by cross multiplying and then dividing..

195 * 1 = 195/3 = 65

This tells you that they are traveling 65 miles per hour. Now with this you will simply have to multiply 65 by 5 to tell you how far they would be traveling in 5 hours with the given speed...

65 * 5 = 325

Your answer of 325 miles tells you how far they traveled.

Hope it Helped!

The average number of earthquakes that occur in Los Angeles over one month is 36. Assume the standard deviation is 3.6. if a ran

Ghella [55]

Answer: 0.9927

Step-by-step explanation:

We assume that the number of earthquakes that occur in Los Angeles follows normal distribution.

As per given , we have

$\mu=36\\\\ \sigma= 3.6$

Sample size : n= 35

Let $\overline{x}$ be the sample mean.

Now ,

$P(34$

Hence, the probability that the mean of the sample is between 34 and 37.5. is 0.9927 .
