A computer manufacturer conducted a survey. It showed that a younger customer will not necessarily purchase a lower or higher priced computer. What is likely true?

1. There is no correlation between age and purchase price.

2. There is a correlation between age and purchase price. There may or may not be causation. Further studies would have to be done to determine this.

3. There is a correlation between age and purchase price. There is probably also causation. This is because there is likely a decrease in the purchase price with a decrease in age.

Option 1

Step-by-step explanation:

From the conclusion drawn by the computer manufacturer, we can assume that there is no correlation between the age and purchase price. The customer would not necessarily purchase a lower or higher priced computer.

Here we can assume that purchasing the computer all depends on the amount of money present on the customer.

step-by-step explanation:

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.
