Astudent is experimenting with
lightning rods and places one
into the ground. she finds that
the approximate length of rod
above ground is 5/7 of a yard
and the approximate length
below ground is 1/3 of a yard.
how many times farther above
the ground is the lightning rod
than below the ground?

|2x - 6| > 10 {x|x < -8 or x > 2} {x|x < -2 or x > 8} {x|-2 < x < 8}

Select quivalent or not equivalent to indicate whether the expression above is equivalent or not equivalent to the values or expressions in the last column.

Among the most famous of all meteor showers are the perseids, which occur each year in early august. in some areas the frequency of visible perseids can be as high as 40 per hour. given that such sightings are poisson events, calculate the probability that an observer who has just seen a meteor will have to wait at least five minutes before seeing another.
