Calculate the total number of holes in the valence band using a similar approach to the one used in class for conduction electrons. Be careful with your assumptions for the zero value of energy. (a) First prove that the probability of occupation of a hole is F(Eh) β exp(β(EF β Eh)/kT) (b) Show that the total number of holes is given by h = 4.84x1015 ( mh β mo ) 3 2 T 3 2 exp [β EG 2kT] Be sure the integral is from β[infinity] to Ev.

Arianna is buying plants for her garden. she buys 15 flowering plants for $96. pink flowering plants sell for $8, and purple flowering plants sell for $5. how many pink flowering plants did arianna buy? i figured out the answer! the answer is 7. 8x +5y = 96 plug in 7 for x 8 (7) + 5y = 96 56 + 5y = 96 subtract 56 from both sides 5y/y = 40/5 y = 8 she bought 7 pink and 8 purple plants
