math or statistics question

Trying to figure out the math behind something
If the 7 day average of daily covid cases is 1046 how does the 7 day average per million come to 1182.

Also is there any other info that I need to know to work this out? like the actual population maybe?

Sorry im dumb asf and just trying to figure this out.

Let X = 1046 be the 7-day average number of cases (using a 7 day average smooths out daily anamalies in testing, reporting, etc.)

Let Y be the total number of people. It is unknown.

Let F = X / Y be the fraction of people who caught Covid, on average.

Let Z = 1,000,000 * F be the number of infections per million people.

We know Z ~ 1182.

We can solve for Y using the equations above:

Y = X / F
= X / ( Z / 1000000 )
= 1,000,000 * X / Z
~ 1,000,000 * 1046 / 1182
~ 884,941
