Answer:

Maria

Step-by-step explanation:

A typical snake bite delivers 0.0045 grams of venom.

Maria wrote it in scientific notation as 4.5\times 10^{-3}

Tammy wrote it in scientific notation as 4.5\times 10^{3}

Any number can be written in the form of scientific notation as follows :

N=a\times 10^b (a is real no and b is integer)

The given no is 0.0045.

There are 2 zeroes before 4. Also the decimal is there before 2 zeroes.

0.0045=\dfrac{45}{10000}\\\\=\dfrac{45}{10}\times \dfrac{1}{1000}\\\\=4.5\times 10^{-3}

Hence, Maria is correct.
