Answer
20% for the first one
Answer:
6x + 6y just add all the 2x then 2y
R^2/2(pi/180*D-sin(D)) is the formula so 6^2/2(pi/180*120-sin(120)) is the problem which comes to about 22cm^2
Answer: 2.46
Step-by-step explanation:
Formula for x-score is given by :-
, where = Sample mean , = population mean, = population standard deviation, n= sample size.
As per given , n=10
= $29,056
= $3,339
= $31,650
Then,
Hence, the z-score = 2.46
