At a particular food processing factory, a machine is supposed to package mixed nuts such that each package contains 50% peanuts, 20% hazelnuts, 20% cashews, and 10% pecans. a randomly-selected can containing 500 of these mixed nuts was found to have 271 peanuts, 108 hazelnuts, 78 cashews, and 43 pecans. at the 5% significance level, determine whether the machine is mixing the nuts in the proper ratio.

It is the proper ratio.

Step-by-step explanation: All of the numbers added together would make the 500 mixed nuts that it mentioned which would be 100%

271 plus 108 plus 78 plus 43 = 500

domain is all the x values included in the

0 ≤ x ≤ 2

range is all the y values of the graph

-2 ≤ y ≤ 2

***keep in mind that there are different ways to show domain and range

hope this !
