Answer:
77.78 mph
Step-by-step explanation:
[1] So we know that someone is driving 350 miles and it takes / took them 4 1/2 hours. I am going to change 4 1/2 to 4.5 for the sake of making it easier.
[2] Miles per hour, is, as it says, miles per hour. Aka, (your time is almost always on the bottom / the y)
[3] So, that being said, to solve you will but 350 over 4.5 like this: which calcuates to arounddd 77.78!
(I hope this is correct, I was slightly confused by the wording. Have a nice day!)
The most appropriate choice for Probability of an event will be given by-
P(7) =
What is Probability?
Probability gives us the information about how likely an event is going to occur
Probability is calculated by Number of favourable outcomes divided by the total number of outcomes.
Probability of any event is greater than or equal to zero and less than or equal to 1.
Probability of sure event is 1 and probability of unsure event is 0.
Here,
Sample space = {6, 7, 8}
Total number of outcomes = 3
Favourable outcomes = {7}
Number of favourable outcomes = 1
Probability of getting a 7 = P(7) =
