A researcher wanted to compare the final test scores of students who used two different types of study materials. The researcher randomly selected two samples of 20 students using each type of material and determined the final test score of each student. The table shows the mean final score and the mean absolute deviation (MAD) for each sample. Study material Mean (%) MAD 1 94 5 2 90 2 Calculate the means-to-MAD ratio. Can the researcher conclude that Material 1 leads to higher final test scores? Select from the drop-down menus to correctly answer the question. The researcher conclude that Material 1 leads to higher final test scores because the distributions of the scores in the two samples are .

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:

mark brainliest!

point m is on plane r

i need the statement

step-by-step explanation:

they r 125, and 216

so the sequence goes 1,8,27,64,125,216
