As part of a statistics project, a teacher brings a bag of marbles containing 800 white marbles and 300 red marbles. She tells the students the bag contains 1100 total marbles, and asks her students to determine how many red marbles are in the bag without counting them. A student randomly draws 200 marbles from the bag. Of the 200 marbles, 56 are red. i) The data collection method can best be described as.
A) Survey
B) Clinical study
C) Census
D) Controlled study
ii) The target population consists of .
A) The 56 red marbles drawn by the student.
B) The 200 marbles drawn by the student.
C) The 1100 marbles in the bag.
D) The 300 red marbles in the bag.
E) None of the above
iii) The sample consists of .
A) The 200 marbles drawn by the student.
B) The 300 red marbles in the bag.
C) The 1100 marbles in the bag.
D) The 56 red marbles drawn by the student.
E) None of the above.
iv) Based on the sample, the student would estimate that marbles in the bag were red.

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.

step-by-step explanation:

mixtures containing substances that get attracted to magnet can be separated using a magnet. we can separate iron from a mixture of sand and iron, as only iron attracts to the magnet.
