Inga, kai, and jason volunteer in the school library. they want to find the average number of pages of a library book. it would be unreasonable to calculate the number of pages in every book to find the average. they decide they need to find a valid sample. inga suggests choosing 100 books from the history section to get a sample. kai suggests randomly selecting 100 books from the library's entire catalog. jason suggests using 100 books from the teen fiction section to get a sample. who suggested the best way to produce a random sample that is not biased?

Kai

Step-by-step explanation:

I did the assignment and got it correct

5x+2x=49

7x=49

x=7. 35 apples

answer:

given the linear inequality :

add 2y to both sides we get;

simplify:

add 12 to both sides of an equation;

simplify:

divide both sides by 2 we get;

or

the related equation for the inequality equation [1] is;

y-intercepts defined as the graph crosses the y-axis.

substitute x =0 in [2] to solve for y;

y = 6

x-intercepts defined as the graph crosses the x-axis.

substitute value y = 0 to solve for x;

subtract 6 from both sides we get

multiply both sides by 2 we get;

or

x = -12

now, plot these point (0, 6) and (-12, 0) on graph as shown below and shade the graph below the solid line.
