A survey conducted asked 1,025 people who work in an office setting whether wearing a t-shirt is appropriate. Among those surveyed, 81% said wearing a t-shirt is appropriate.  Find the number of people in the survey who stated that wearing a t-shirt is appropriate.

Step-by-step explanation:

that is states that don't mean insult each of the following real rational equation

871

Step-by-step explanation:

81% of 1025 = 871.25

round that down to 871

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.
