In interval notation, square brackets indicate that a function can take on that value (or uses a less/greater than or equal to sign). Parenthesis indicate that a function cannot take on that value (or uses a less/greater than sign).
In the case of the given set, both inequality signs are less/greater than or equal to. This indicates to us that we will use brackets in both instances because the set can be equal to -2 and 2.
Answer: [-2,2]

Answer:
100 Miles
Step-by-step explanation:
Let it be for x miles.
40+15+0.25x=45+0.35x
10 =0.1x
x=100
The mile is 45+0.35*100= 80 or 40+15+0.25*100 =80

Since, the variance calculated on 34 scores is equal to 14.94.
We have to determine the standard deviation.
Relationship between Variance and standard deviation is:
Standard deviation = 
Substituting the value of Variance, to evaluate the standard deviation.
We get,
Standard deviation = 
= 3.865
= 3.87
Therefore, the standard deviation is 3.87
