(-2,-5)
because
y= y
x^2+10x+ 11 = x^2+x -7
10x-x = -7-11
9x=-18
x=-2
so y = (-2)^2+(-2)-7 = 4-2-7 =-5
<h3>
Answer: 0.21</h3>
======================================================
Explanation:
All of the values in the P(x) column must add to 1.
The value 1 in probability means 100%
Let y be the missing value in the table
0.25+y+0.39+0.15 = 1
y+0.79 = 1
y = 1-0.79
y = 0.21
The probability that x = 4 is 0.21
In other words, P(4) = 0.21
Or that we have a 21% chance of having x = 4 happen.
