Answer:
So then the best option would be:
a. 1/25
Step-by-step explanation:
For this case we assume that the sample space for the numbers is :
And the sample space for the numbers is:
Both sampling spaces with a size of 5.
We define the following events:
A="We select a 2 from the numbers"
B= "We select a E from the letters"
We can find the individual probabilities for each event like this:
And assuming independence we can find the probability required like this:
The last probability is the probability of obtain obtain a 2 AND an E
So then the best option would be:
a. 1/25
Answer:
-3.33 ft. per second
Step-by-step explanation:
The rate of change of an object can be calculated by finding the difference in position between the starting point and end point, and then dividing by the difference in time between the starting time and end time. Using the values provided in the question we can calculate the following
= 3.33 ft. per second
With the calculation above we can see that the rate of change during these 15 seconds is 3.33 ft. per second. Since the endpoint is further down below ground level then we were descending which means that the rate of change would be a negative (-3.33 ft. per second)
