To the nearest would be about 52
Answer: Jack can fill his feeder 12 times with 4 pounds of birdseed.
Step-by-step explanation:
You need to analize the information given in the exercise, You know that every time Jack fills the feeder, he put
pounds into it.
Then, in order to solve this exercise, let "x" represents the number of times that Jack can fill his feeder with 4 pounds of birdseed.
Keeping on mind the data provided in the exercise, you can set up de following proportion:

Finally, you must solve for "x" in order to find its value.
You get that this is:

Therefore, you can conclude that Jack can fill his feeder 12 times with 4 pounds of birdseed.
The <em><u>correct answer</u></em> is:
She can determine that while there is an association between the variables, there is no correlation, and she cannot determine causation.
Explanation:
Since there is an arch shape to her graph, we know that as one variable changes, the other changes in the same manner. This means there is an association between the variables.
However, since the graph is not linear, there is no correlation between the variables. Since there is no correlation, we cannot determine causation.
Answer: you can use Pythagorean theorem
, which formula is
, "a" and "b" are the sides, and "c" is the hypotenuse (the longest side, the side opposite to the 90 degree angle)
<em>Example:</em>
If they give that one side is 2 inches and the other side is 4 and you need to find the hypotenuse it would be like this:
1) plug the numbers to the formula

2) solve the exponents of the numbers given (not the letter, in this case "c")
16 + 36 = 
3) combine like terms (in this case 16 +36)
52 = 
4) Finally, Find the square root of "c" to remove its exponent and do the same to the other side, in this case 52)

(square root of 52 rounded to the nearest hundred is 7.21)
7.21 = c

So 7.21 is your missing side in this example</em></u></h3><h3>look up Pythagorean theorem Khan Academy</h3>
