Correlation
- Correlation is a technique that help us to find or define a relationship between two variables.
- It is a measure of linear relationship between two quantities.
- A positive correlation means that an increase in one quantity leads to an increase in another quantity
- A negative correlation means with increase in one quantity the other quantity decreases.
- Values between 0 and -0.3 tells about a weak negative linear relationship, values between -0.3 and -0.7 shows a moderate negative correlation and a correlation value of of -0.7 and -1.0 states a strong negative linear relationship.
Anxiety symptoms and life satisfaction are negatively correlated. As life satisfaction increases the anxiety symptoms decreases.
Thus, a moderate correlation between them can be expressed by a correlation coefficient of -0.5

It would take 
hour to complete the entire trip.
Step-by-step explanation:
Given,
Distance covered = 
= 
miles
Time taken =
hour
We know that;
Distance = Speed * Time
Multiplying both sides by 3
91 = Speed
Bob was driving at 91 miles per hour.
Now,
Distance to cover = 100 miles
Time required = x
Distance = Speed * Time
Dividing both sides by 91
It would take hour to complete the entire trip.
