Answer:
D
Step-by-step explanation:
I believe D is the answer because 10^-3 = 0.001 ; there is only one answer that has 0.001 in the correct exponential form (10^-3).
Also, for the future, to correctly figure out what the exponential form, try to take the number given, let's say 10^-2 (^ means to the power of), and move the decimal place to the left, two decimal places (because of the power of -2).
Ex: 10.0 --> 0.01

Answer:
300 girls
Step-by-step explanation:
100% represents the whole school
To calculate this amount divide 99 by 33% to find 1% and multiply by 100
school population = × 100 = 3 × 100 = 300
