Answer:
a) m =589.734kg
b) n = 8 people (rounded down)
Step-by-step explanation:
The first step is to calculate the maximum load after safety considerations (
Since we know that the maximum tension the cables can withstand is 19500N (or 19.5kN). To calculate ( we multiply this value by
(as per the given safety consideration.
Hence
a) Now to find the maximum load in kgs, we use the following formula
Where
= mass of elevator
= maximum load
= acceleration due to gravity
= maximum acceleration of elevator
Inputting the values and solving
Hence the maximum load is m =589.734kg
b) To find the number of people (n) we divide the value of m by 70kg
n = 589.734 / 70
n = 8.42 or 8 people
Answer:
a) The third quartile Q₃ = 56.45
b) Variance
Step-by-step explanation:
Given that :
= 30.8
Median = 48.5
Mean = 42
a) The mean is less than median; thus the expression showing the coefficient of skewness is given by the formula :
Divide both sides by 1.38
b) The objective here is to determine the approximate value of the variance;
Using the relation
Variance =
