HELP PLEASE BRAINLEST FOR ANSWER Which sample is biased? Which is not baised
A.
A book store owner surveys 50 customers to find out if they like to read.

B.
Two students survey 100 people on the street asking for their favorite soda.

C.
A phone system randomly calls people living in a city asking for their favorite store.

D.
A computer program randomly emails a survey to customers to see if they are satisfied with the service.

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.

i would you but i don't under stand the qustion
