In science class, the average score on a lab report is 82 points, with all students scoring within 3.2 points of the average. if
gregori [183]

The absolute value equation that represents the minimum and maximum scores is:

|x - 82| = 3.2.

<h3>What is the absolute value function?</h3>

The absolute value function is defined by:

  • f(x) = x, x ≥ 0.
  • f(x) = x, x < 0.

It measures the distance of a point x to the origin.

For this problem, the distance between the minimum and the maximum scores and the mean is of 3.2, that is, the difference between these scores x and the mean of 82 is of 3.2, hence the absolute value equation that represents this situation is given by:

|x - 82| = 3.2.

A cylinder has a surface area of 339 square centimeters and a radius of 6 centimeters. Estimate the volume of the cylinder to th
Andre45 [30]
SA=2hpir+2pir^2=2pir(h+r)
V=hpir^2

SA=339
r=6

339=2pir(h+r)
339=2pi3(h+3)
339=6pi(h+3)
divide both sides by 6pi
56.5/pi=h+3
minus 3 both sides
(56.5/pi)-3=h
(56.5-3pi)/pi=h
v=hpir^2
v=((56.5-3pi)/pi)(pi)(6)^2
v=(56.5-3pi)(36)
v=2034-108pi
use pi=3.141592
