Answer:
1 7/8
Step-by-step explanation:
2 5/8
+1 7/8= 4 1/2
- 7=3+4
- 5+3=8
- 2 5/8 + 3/8= 3
- 3 + 1= 4
- 4 + 4/8= 4 4/8
- 4 4/8 = 4 1/2
This cannot be fit into a normal distribution. While the first 7 runners all have times relatively close, the time of the last runner is an outlier, as it is too far from the other data points. The standard deviation is calculated by taking the mean, subtracting each value from the mean, squaring the deviations, adding these, then dividing by the number of data points (7), and taking the square root. This gives an answer of SD = 0.1107.
Answer:
The number of hours.
Step-by-step explanation:
The dependent variable is what you are mesuaring.
The domain is {-8}
The range is {5,6,7,8}
The relation is not a function as the domain value -8 maps to multiple values. All domain values in a relation needs to map to exactly one range value for it be a function.
