Answer 1

The percentage of Ottawa's population that speaks only English and not French is 61%. The number of people who speak both English and French is 354,600, which can be written in scientific notation as 3.546 x 10^5.

Step-by-step explanation:

To calculate the percentage of the population of Ottawa that speaks English but not French:

• We know that 97% of the population speaks English, and 38% speak French.
• 36% of the population speak both English and French. Therefore, the percentage that speaks only English and not French is 97% - 36% = 61%.

To find the number of people in Ottawa who speak both English and French:

1. The total population of Ottawa is 985,000.
2. To calculate this number, we'll take the percentage that speaks both languages, which is 36%, and apply it to the total population: 985,000 x 0.36 = 354,600 people.
3. This can be expressed in scientific notation as 3.546 x 10^5.
