Answer:
2. The standard deviation of the distances in kilometers is larger.
Step-by-step explanation:
Let us assume the distance of car travel in miles is x
And, the distance of car travel in kilometers is y
Given that
1 mile = 1.6 km
That means
y = 1.6x
Therefore
The standard deviation of y = 1.6 × (standard deviation of x)
The above equation represents
The standard deviation of y > standard deviation of x
hence, the correct option is 2.
Answer:
expanded : 3a + 9 + 2a answer: 5a + 9
Step-by-step explanation:
so 3*a = 3a and 3*3 = 9 + 2a
3a + 9 + 2a
5a + 9
Answer:
Assuming population data
Assuming sample data
Step-by-step explanation:
For this case we have the following data given:
736.352, 736.363, 736.375, 736.324, 736.358, and 736.383.
The first step in order to calculate the standard deviation is calculate the mean.
Assuming population data
The value for the mean would be:
And the population variance would be given by:
And we got
And the deviation would be just the square root of the variance:
Assuming sample data
The value for the mean would be:
And the population variance would be given by:
And we got
And the deviation would be just the square root of the variance:
Answer:
Irrational
Step-by-step explanation:
Since √3 is a non-terminating decimal (it repeats forever), it will be an irrational number.
