<span>The biggest number of groups that can be formed is 6, because six is the greatest common factor of 12 and 42. There will be 2 coaches in each group because 6 x 2 = 12 and 7 players in each group because 7 x 6 = 42.</span>
Step-by-step explanation: standard score is equal to sample mean - population mean all over standard deviation.
Z=×-u/sigma. Where sigma is standard deviation. 267985-254876=13109. 13109/5834=2.247. Therefore the standard score is 2.247. The price they paid for the house is usual.
Take you the common factors. those are 2 and x. So if you divided 2x^2 by 2x you end with only one x. and if you divided 4x by 2x you end with 2. The final answer should look like 2x(x+2)=2x^2+4x
