Let X represent the time it takes from when someone enters the line for a roller coaster until they exit on the other side. Consider the probability model defined by the cumulative distribution function given below. 0 x < 3 F(x) = (x-3)/1.27 3 < x < 4.27 1 x > 4.27 a) What is E(X)? Give your answer to three decimal places. b) What is the value c such that P(X < c) = 0.22? Give your answer to four decimal places.

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

step-by-step explanation:

given   that triangle lno is congruent to triangle lnm.

we have to fill up the blanks in the given question.

according to above order of congruency   kept in mind we can say that

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

ln ≅ ln due to common in both.

hence, by sas congruency,

the side angle side rule   states that if two sides and the included angle of one triangle are congruent to another triangle, then these two triangles are congruent.

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3
