The thicknesses of 7373 randomly selected linoleum tiles were found to have a variance of 3.143.14. Construct the 90%90% confidence interval for the population variance of the thicknesses of all linoleum tiles in this factory. Round your answers to two decimal places.

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.

step-by-step explanation:

let pq = qr = rs = x, and xz = y and zu = z.

if the horizontal lines are parallel, then corresponding segments are in proportion:

substitute:

therefore 3 = y = z.

xu = y + z → xu = 3 + 3 = 6

=

x=0.8898305 is the answer to that equation
