## 0.0078125 in scientific notation is written as 7.8125 x 10^-3.

## The length of a wasp's stinger, 2.67x10^-3 meter, in decimal notation is 0.00267 meters.

## The correct answer is 6.5 × 10^-8.

## To write the speed of light, 671,000,000 miles per hour, in scientific notation, it would be 6.71 × 10^8.

## To calculate the number of times an average person blinks in a year, we need to multiply the number of blinks per hour (15) by the number of hours in a day (24) and then by the number of days in a year (365).

15 blinks/hour × 24 hours/day × 365 days/year = 131,400 blinks/year

So, an average person blinks 131,400 times in a year. In scientific notation, this is written as 1.314 × 10^5.
