The mean incubation time for a type of fertilized egg kept at a certain temperature is 25 days. suppose that the incubation times are approximately normally distributed with a standard deviation of 1 day. complete parts (a) through(e) below.

(a) draw a normal model that describes egg incubation times of these fertilized eggs.

(b) find and interpret the probability that a randomly selected fertilized egg hatches in less than 23 days.

the probability that a randomly selected fertilized egg hatches in less than 23 days is (round to four decimal places asneeded.)

Given: ad¯¯¯¯¯ is an altitude. prove: ab2+ac2=cb2 right triangle a b c with right angle a. point d lies on side b c and segment a d is drawn. angle a d c is a right angle. drag and drop a reason into each box to correctly complete the two-column proof. statement reason ad¯¯¯¯¯ is an altitude, and ∠bac is a right angle. given ∠adb and ∠adc are right angles. definition of altitude ∠bac≅∠bda ? ∠bac≅∠adc ? ∠b≅∠b ? ∠c≅∠c reflexive property of congruence △abc∼△dba ? △abc∼△dac aa similarity postulate abbd=cbab ? ab2=(cb)(bd) cross multiply and simplify. acdc=cbac polygon similarity postulate ac2=(cb)(dc) cross multiply and simplify. ab2+ac2=ab2+(cb)(dc) addition property of equality ab2+ac2=(cb)(bd)+(cb)(dc) substitution property of equality ab2+ac2=(cb)(bd+dc) ? bd+dc=cb segment addition postulate ab2+ac2=cb2 substitution property of equality
