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!

Calculate the ratio of ab to ac and the ratio of ad to dc . round your answers to the hundredths place. what do you notice about
yanalaym [24]

The ratio of AB to AC and the ratio of AD to DC is 1 : 2 each respectively. They are equivalent ratios.

<h3>Ratios and proportions</h3><h3 />

A ratio means a comparison of two different quantities while proportion is an equality of two ratios.

  • AB = 5 in
  • AC = 10 in
  • AD = 4 in
  • DC = 8 in

Ratio of AB to AC = 5 in : 10 in

= 5 / 10

= 1 / 2

= 1 : 2

Ratio of AD to DC = 4 in : 8 in

= 4 / 8

= 1 / 2

= 1 : 2

Therefore, the ratio of AB to AC and the ratio of AD to DC is 1 : 2 each respectively. They are equivalent ratios.

Graph to answers i put
maksim [4K]

Answer:

The domain of f is {x : x ∈ R, -7 ≤ x ≤ 7} ⇒ [-7, 7]

Step-by-step explanation:

<em>The domain of a function is </em><em>all the values of x</em><em> make the function defined</em>

In the given graph

∵ The graph drawn from x = -7 to x = 7 and from y = -6 to y = 4

→ That means the values of x started from -7 and ended at x = 7

∵ The coordinates of the starting point of the graph of f are (-7, -5)

∵ The coordinates of the ending point of the graph of f are (7, 3)

∴ -7 ≤ x ≤ 7

∵ Values of x are the domain of the function

∴ The domain of the function is -7 ≤ x ≤ 7

∴ The domain of f = {x : x ∈ R, -7 ≤ x ≤ 7} ⇒ [-7, 7]

cricket20 [7]

Answer:

$95

Step-by-step explanation:

We are told that Carmen makes a monthly payment of no more than 200 dollars. We then see her going above the 200 dollars so we look to the tens and ones place. We see that we now have 25, 45, and 35 dollars. Add them up and you get 105 dollars. 200-105=95 so your awnser is $95.
