Answer:
Option A
Step-by-step explanation:
Number of components assembled by the new employee per day,
N(t) = 
Number of components assembled by the experienced employee per day,
E(t) = 
Difference in number of components assembled per day by experienced ane new employee
D(t)= E(t) - N(t)
D(t) = 
= 
= 
= 
= 
Therefore, Option A will be the answer.
Answer: 68
Step-by-step explanation: Complementary angles are angles that add up to 90. So, you need to do 90-22=68.
I think the answer is 120
The probability that the reaction time for this density function is at most 2.5 seconds is equal to 0.9.
<h3>What is a density function?</h3>
A density function can be defined as a type of function which is used to represent the density of a continuous random variable that lies within a specific range.
<h3>How to calculate the probability that reaction time is at most 2.5 seconds?</h3>
P(X ≤ 2.5) = Fx(2.5)
Fx(2.5) = 3/2 - 3/2(2.5)
Fx(2.5) = 3/2 - 3/5
Fx(2.5) = 0.9.
