I guess you're asking the football court?? cuz a football is sphere shape.
for a rectangular shape just add the width and length together then mmultiply it by 2.
so
(64+118)x2
= 364 m2
A(n)=-1(-3^n)
3, -9, 27, -81
B because it’s the only one that doesn’t double in value
To solve for the coefficient of variation you will need this formula:
CV = (SD/X) x 100
Where: CV = Coefficient of Variance
X = Mean/average
SD = Standard Deviation
To determine which one is more variable, just get the coefficient of both and compare.
AGE SALARY
CV = (6/55) x 100 CV = (4,100/37,000) x 100
= 10.90 = 11.08
Based on the results, salary is more variable because 10.90<11.08.
