Any number from 495 to 504 can be the answer.
Answer:
y = 2
Step-by-step explanation:
3y - 4 = 6 - 2y
→ Add 2y to both sides to isolate 6
5y - 4 = 6
→ Add 4 to both sides to isolate 5y
5y = 10
→ Divide both sides by 5 to find the value of y
y = 2
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.
