176 feet/2 seconds
135 feet means that it reached the river within 2 seconds. it reached the river in 1.545 seconds
Answer:
Probability of having broken glass = 0.1933
Probability of not having broken glass = 0.8067
Step-by-step explanation:
The Treatment table in the file attached to the given question is written out and completed below;
Treatment
Response Smashed into Hit Control Total
Yes 16 7 6 29
No 34 43 44 121
Total: 50 50 50 150
Using relative frequencies,
the distribution of responses about whether there was broken glass at the accident for the subjects in this study can be computed as follows:
Probability of having broken glass = 
Probability of having broken glass = 0.1933
Probability of not having broken glass = 
Probability of not having broken glass = 0.8067

the first ratio is 5:10 since it is easier to work with big numbers let's start by multiplying it by 2 to get something
Now we have 10:20 we can divide this by 10 and get the ratio 1:2
1:2 equals 1 mile:2 minutes which is 1 mile in 2 minutes!
Have a nice day and I hope this helps!
