Suppose that wait times at a dentist's office follow an Exponential distribution, with an expected wait time of 29 minutes.
Round answers to one decimal if needed. To ensure accuracy, keep the decay parameter as a fraction
(don't round) when doing calculations.

A) What is the percentile of a 28 minute wait?

step-by-step explanation:

it has changed from the width and the height.

step-by-step explanation:

you can't solve x because it is 2 linear equation and you only have one equation

< xcy ≅ < xby

step-by-step explanation:

in δcax and δbax,

so, δcax ≅ δbax (side-angle-side or sas)

since δcax ≅ δbax, we can conclude < acx ≅ < abx

in δacy and δaby,

so, δacy ≅ δaby (side-angle-side or sas)

since δacy ≅ δaby, we can conclude < acy ≅ < aby

now,

< acy ≅ < aby

=> < acx + < xcy ≅ < abx + < xby

=> < acx + < xcy ≅ < acx + < xby   (since < acx ≅ < abx already proved above)

subtracting < acx from both sides, we get

< acx + < xcy -< acx ≅ < acx + < xby -< acx

cancelling out < acx and -< acx from both sides, we get

< xcy ≅ < xby (proved)
