Answer:
The variance of the data is 29966.3.
Step-by-step explanation:
The given data set is
175, 349, 234, 512, 638, 549, 500, 611
We need to find the variance to the nearest hundredth decimal place.
Mean of the data
where, n is number of observation.
The mean of the data is 446.
Therefore, the variance of the data is 29966.3.
a = 90
b = 28
c = 68
d = 22
your answer would be A.)12
Step-by-step explanation: You needed to find out what number you can put for it to add up to the number on the bottom line, 17. So you would add (12+5=17) , And you would get the same number as the number on the bottom line.
