-0 good luck queen hdhdhdjf
<span>(-6+7)(-4) encloses -6+7 within parentheses, so we MUST perform -6+7 first. That comes to 1.
Then we have ( 1 )(-4), which equals -4 (answer).
Note: Sounds as tho' several possible answers were given, but you haven't shared them. Share all parts of every question in the future, OK? Thx.

<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.
Answer:
not sure if this is what you're looking for but the function would be
f(x) = x-5
