"apply quickselect to find the median of the list of numbers 9, 12, 5, 17, 20, 30, 8."

12

Step-by-step explanation:

In statistics, the median is the value that separates the higher half from the lower half of a data sample. This means that it is the "middle" value of a data sample. In order to find the median, you need to place the numbers of your data sample in order of value, and identify the middle point. If two sets of numbers are in the middle, then you need to find the middle point between the two (by adding them and then dividing them by two).

Therefore:

5, 8, 9, 12, 17, 20, 30

it will be a cylinder. with a diameter of 8 and 4 single pieces high

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
