(1 point) A computer retail store has 8 personal computers in stock. A buyer wants to purchase 4 of them. Unknown to either the retail store or the buyer, 4 of the computers in stock have defective hard drives. Assume that the computers are selected at random. (a) In how many different ways can the 4 computers be chosen

Total no  of different ways can the 4 computers be chosen  = 70

Step-by-step explanation:

Given -

A computer retail store has 8 personal computers in stock.A buyer wants to purchase 4 of them.

(Using the combination formula)

The combination of n events taking r at a time =

where n = 8 and r = 4

Total no  of different ways can the 4 computers be chosen =

    =  

=   70

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.
