What is the likability of a earthquake and volcanic eruption happening in Minnesota
2. ## geometry

ABC is a triangle with AC=139 and BC=178. Points D and E are the midpoints of BC and ACrespectively. Given that AD and BE are perpendicular to each other, what is the length of AB?
3. ## statics

A bag contains 4 balls, each of which have a positive integer written on it. Let X be the random variable of the value written on a single ball drawn from the bucket. If E[X]=8, what is the maximum possible value of E[X^2]?
4. ## geometry (help steve)

A circle of radius 1 is drawn in the plane. Four non-overlapping circles each of radius 1, are drawn (externally) tangential to the original circle. An angle γis chosen uniformly at random in the interval [0,2π). The probability that a half ray
5. ## physics

An airplane of a certain density and shape flies at a constant speed. To do so, it must fly with a certain velocity v0. If the size of the airplane is scaled up in length, width, and height by a factor of two, it can only fly above a new velocity v1.
