The following dataset will be used to answer questions 1 to 14. This dataset
represents a random sample of data from a local computer shop. The analyst collected
information from 7 randomly selected months, months 1 to 7. The variable Sales
denotes the number of computers the store sold each month. The variable Adv
denotes the number of ads the computer shop posted online. The analyst was asked
to asses the extent to which increasing the number of ads run online influences sales.

Compute n-1 and enter your answer in the numerical box below.

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.

5 feet of chain cost $9

so the answer is 1.80

she will do 520 after 52 weeks

hope this : )
