Step-by-step explanation:

As Jean writes 75,000,000 in scientific notation as 75.

This is INCORRECT!

Here is the correct solution:

Given the number

75,000,000

Let us write the number 75000000 in scientific notation

We know that scientific notation is of the form where and b is an integer.

Move the decimal point to the left to create a new number from 1 up to 10.

Count the number of times you moved the decimal point

b = 7

so

Remove the trailing zeros

Therefore, we conclude that:

75,000,000 in scientific notation: 7.5 × 10⁷

add the numbers under frequency to find the total number:

5 + 8 +7 + 4 + 0 +1 = 25

the answer is 25.

i think the answer is c sorry if it's wrong
