The unit of measurement used to describe the energy produced by an atomic particle
accelerator is the electron volt (eV). Shown
below are the amounts of energy produced
by two versions of a particle accelerator.
Original Model
New Model
2x100 eV
8x10" eV
How many more electron volts are
produced by the new model as compared
with the original model?
A 7.8 X 10"
B 7.8 X 100
C 7.8 x 10°
D 6X10
E 4X10

Exercise: counting committees 0.0/2.0 puntos (calificable) we start with a pool of n people. a chaired committee consists of k≥1 members, out of whom one member is designated as the chairperson. the expression k(nk) can be interpreted as the number of possible chaired committees with k members. this is because we have (nk) choices for the k members, and once the members are chosen, there are then k choices for the chairperson. thus, c=∑k=1nk(nk) is the total number of possible chaired committees of any size. find the value of c (as a function of n ) by thinking about a different way of forming a chaired committee: first choose the chairperson, then choose the other members of the committee. the answer is of the form c=(α+nβ)2γn+δ. what are the values of α , β , γ , and δ ?
