BINOMCDF on calculator question
max2010maxim [7]

Explanation:

For the purpose of filling in the table, the BINOMPDF function is more appropriate. The table is asking for p(x)--not p(n≤x), which is what the CDF function gives you.

If you want to use the binomcdf function, the lower and upper limits should probably be the same: 0,0 or 1,1 or 2,2 and so on up to 5,5.

The binomcdf function on my TI-84 calculator only has the upper limit, so I would need to subtract the previous value to find the table entry for p(x).

Use the Elimination method to solve the system of equations.<br><br> X+y=-3<br> X-y=13
svlad2 [7]
X + y = -3
<u>x -  y = 13</u>
    <u>2x</u> = <u>10</u>
     2      2
      x = 5
  x + y = -3
  5 + y = -3
<u>- 5         - 5</u>
        y = -8
  (x, y) = (5, -8)
