Company XYZ know that replacement times for the DVD players it produces are normally distributed with a mean of 8 years and a standard deviation of 1.8 years. Find the probability that a randomly selected DVD player will have a replacement time less than 2.2 years? P(X < 2.2 years)

Me! 50 points! why does when we come home, our door is unlocked and there is grease on the door knob, me solve this , and i don't know what category this goes under

Juliana says that she can use the patterns of equivalent ratios in the multiplication table below to write an infinite number of ratios that are equivalent to 6: 10. which statement explains whether juliana is correct? she is correct because she can multiply 6 and 10 by any number to form an equivalent ratio. she is correct because 6: 10 can be written as 1: 2 and there are an infinite number of ratios for 1: 2. she is not correct because the multiplication table does not include multiples of 10. she is not correct because 6: 10 is equivalent to 3: 5 and there are only 9 ratios in the multiplication table that are equivalent to 3: 5.

If y varies directly as x2 and y=6 when x=6, find the constant of variation.
