Like in just a set of numbers .. add them up, then divide by how many numbers are given <- I know that .. as in this, idk.

Number of Bases 0 1 2 3 4 Number of Times 450 194 32 5 11 total at bats \(450+194+32+5+11=692\)

  • anonymous
number of bases \[1\times 194+2\times 32+3\times 5+4\times 11=317\]
anonymous
  • anonymous
\[E(x)=\frac{317}{692}\] it is late so check my arithmetic
anonymous
  • anonymous
AND THAT IS the MEAN and the answer
anonymous
  • anonymous
Oh okay, I get it now. Thank you both. Wait .. I dont divide 692 into 317 right? i just keep it as is?
anonymous
  • anonymous
depends on whether you want a decimal or a fraction
anonymous
  • anonymous
Alright then, thank you (:

WELCOME
anonymous
  • anonymous
you could say \(.458\) rounded
anonymous
  • anonymous
No, I think i just need it fraction form. Thanks once again
