Given: The burning time of a very large candle is normally distributed with mean
of 2500 hours and standard deviation
of 20 hours.
Let X be a random variable that represent the burning time of a very large candle.
Formula: 
For X = 2470
So, the z-score they corresponds to a lifespan of 2470 hours. =-1.5
Hence, the correct option is C.-1.5.

A line that goes through the origin represents a proportional relationship. Since the line passes through zero-zero, it means that the relationship between the number of notebooks and the cost is proportional The unit rate is represented by the point one-y. The point one, two and seventy-five hundredths represents the unit rate, which means each notebook costs two dollars and seventy-five cents.
BPD = 1/2(BD + CA)
BPD = 1/2(70 + 170)
BPD = 1/2(240)
BPD = 120
A full circle = 360 degrees
BC + AD = 360 - 70 - 170
BC+ AD = 360 - 240
BC + AD = 120
