Answer:

1350

Step-by-step explanation:

Initially 90 squirrels were tagged out of a total population of x squirrels.

Similarly, 42 squirrels out of a sample of 630 squirrels had tag

We can use ratio equality to find the total population x.

42:90=620:x

\frac{42}{90} =\frac{630}{x}

Cross multiplying

42 X x = 630 X 90

Dividing both sides by 42

x=\frac{630 X 90}{42} \\=1350

The total number of squirrels in the city park is 1350.

Here are your answer's:

Number three would goes with "no relationship"...…
Number one would goes with "<span>causation</span>".....
Number two goes with "correlation"...…

<u>Correlation is the relationship between more than two things which is why it would go with number to because literacy rates go with the increase of doctors. Causation is like a cause and effect so in this case the cause would be a increase of the population and the effect would be more people who don't have jobs. No relationship would go with number three since how snowfall doesn't have anything to do with personal income. (which is how much a person makes) </u>

Hope this helps!
