The mean of 10 observations is 21 If each score is divided by 3 find the new mean?
The new mean would be 7. The mean is the average of the data. (x1+x2+x3+x4+x5+x6+x7+x8+x9+x10)/10=21 [(x1/3)+(x2/3)+(x3/3)+(x4/3)+(x5/3)+(x6/3)+(x7/3)+(x8/3)+(x9/3)+(x10/3)]/10=? [(1/3)(x1+x2+x3+x4+x5+x6+x7+x8+x9+x10)]/10=? [(x1+x2+x3+x4+x5+x6+x7+x8+x9+x10)/10]/3= 21/3=7

Is your amd phenom x6 processor compatible with a Asus m2a74 motherboard?
No. The Asus M2A74 is only compatible with the Athlon II X2/X3/X4 and the Phenom II X2/X3/X4. However, the MSI 870-G45 is only $69.99 on Newegg.com, and is X6 CPU Certified. It's a good board, and would work perfectly with a Phenom II X6. If you're looking at motherboards, don't just look for a socket match for the Phenom II X6's, look for something in the specifications or on the box that SPECIFICALLY SAYS "X6 CPU Certified" or something similar.
