Lillian can construct a triangle because the sum of any two sides is greater than the third side.
The area is actually 52.5
Answer:
a) The third quartile Q₃ = 56.45
b) The variance = 2633.31
Step-by-step explanation:
a) The coefficient of skewness formula is given as follows;
Plugging in the values, we have;
Solving gives Q₃ = 56.45
b) To determine the variance, we use the skewness formula as follows;
Plugging in the values, we get;
The variance = σ² = 51.32² = 2633.31.
