Identify the type of sampling used in the following situation:

Subscribers to the magazine Sound Alive were assigned numbers. Thirty numbers were selected at random. The subscribers with the chosen numbers were asked to rate a new compact disk player for a "What Subscribers Think" column. (Assume all chosen did respond)

a. Simple Random Sample
b. Stratified Random Sample
c. Voluntary Response
d. Convenience Sample

i think is 3 and 6. this took me 10 min to think.hope to and hope that my answer is brainliest.(follow me )

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.
