Answer:
the approximate probability that the total weight of the passengers exceeds 4668 pounds is 0.0089
Step-by-step explanation:
Using the central limit Theorem
z = (x - u )/Q÷ sqrt n
Where z is the z-score
x is the average weight = 4668/22 = 212.2
u is the passengers average = 194 pounds
Q is standard deviation = 36 pounds
Therefore
z= (212.2 - 194) / 36 ÷ sqrt22
= 18.2/ 36÷ 4.69
= 18.2/7.68
z=2.3698 aprx 2.37
Find the value of 2.37 z-score on the z-table to determine the approximate probability
P(z>2.37) = 0.0089 (from the z-table)
10*50,10*30,10*40 are all the multples
no numbers will evenly add up and multiply to those specific numbers. if you are factoring you cannot factor these numbers or it is already factored as far as it can go.

Answer:
True
Step-by-step explanation:
Based on the expression provided in the question, it can be the statement P(n+1) can be derived from the statement P(n) by the addition of f(n+1) to both sides of the statement P(n). Furthermore, the expression S(n)+f(n+1) can be simplified algebraically to derive an expression S(n+1). Therefore, the above sentence is true.
