The stem-and-leaf plot shows cholesterol readings for a group of
patients. Two additional readings
will be added to the plot.

17 / 3 represents 173.
If the two additional readings
are 158 and 146, by how many
points will the median of the
readings increase?

6 points

EXPLANATION:

Original readings

120, 121, 122, 125, 126, 126, 129, 132, 132, 135, 137, 143, 143, 145, 148, 153, 153, 154, 164, 164, 173

The median is the 11th number (137).

Additional readings added

120, 121, 122, 125, 126, 126, 129, 132, 132, 135, 137, 143, 143, 145, 146, 148, 153, 153, 154, 158, 164, 164, 173

The median is the 12th number (143).

I'm not sure exactly what it means by 'points' but I think that means 143-137, which is 6 points?

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1

answer: y=0 if that is what u r looking for
