<span>15/7 is the best number which completes both equations.If 5/7Ă·1/3 then it becomes 5/7 X 3/1 where 1/3 in denominator becomes 3/1 so that the value is 15/7 then 15/7 multiplied by 1/3 which yields 5/7.So we derive the final answer 5/7.This result involves only simple multiplication and division.</span>

Answer:
none of the above, x=13/2
Step-by-step explanation:
(x-5)2= 3
2x_10=3
2x=13
x=13/2
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
