The box plots compare the exam scores of Ms. Dobson’s class to the rest of the students who took the test in the district. A number line goes from 0 to 110. Mrs. Dobson's class's whiskers range from 40 to 95, and the box ranges from 70 to 80. A line divides the box at 75. District-wide's whiskers range from 15 to 100, and the box ranges from 55 to 75. A line divides the box at 65. Which statement is true about the box plots? Select three options. Ms. Dobson’s class has a smaller range of scores. The district has a greater interquartile range. Fifteen is an outlier for the district’s scores. One hundred is an outlier for the district’s scores. In general, the district’s scores were better than those of Ms. Dobson’s class.

-3

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3

boxplot e is the answer

step-by-step explanation:

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
