Answer:
The probability of randomly selecting a rod that is shorter than 22 cm
P(X<22) = 0.1251
Step-by-step explanation:
<u><em>Step(i):</em></u>-
Given mean of the Population = 25cm
Given standard deviation of the Population = 2.60
Let 'x' be the random variable in normal distribution
Given x=22
<u><em>Step(ii):</em></u>-
The probability of randomly selecting a rod that is shorter than 22 cm
P(X<22) = P( Z<-1.15)
= 1-P(Z>1.15)
= 1-( 0.5+A(1.15)
= 0.5 - A(1.15)
= 0.5 - 0.3749
= 0.1251

Answer:
<h2>4 p.m.</h2>Step-by-step explanation:
We know that a day contains 24 hours in total.
The time already passed will be represented by .
The remaining time would be , becasye half of what has already passed remains until the end of the day.
Basically, the sum of these two expression gives 24 hours in total.
