Abank wishing to increase its customer base advertises that it has the fastest service and that virtually all of its customers are served in less than 10 minutes. a management scientist has studied the service times and concluded that service times are exponentially distributed with a mean of 6 minutes. determine what the bank means when it claims 'virtually all' its customers are served in under 10 minutes.

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.

step-by-step explanation:

what are the statements? and what do you mean by "216 2 1 6"?
