Answer:
The answer of P(3 ≤ X < 7) is 0.367
Step-by-step explanation:
Note that £fx= 1 in a probability mass function the sum of the function is equal to 1.
See attached picture for solution.
Answer:
Can't solve without diagram man...
Next time you ask click the paperclip tool to connect the picture of it otherwise we can't solve it.
collinear points lies in a single line
that means sum of distance between 2 points is equal to distance between end points.
for example if A B and C lies in a line then
AB + BC = AC
here (1,1) , (2,2) and (3, 3) follows the same rule. ao ans is option D

➷ You could apply the difference of two squares rule
Square root 100 to get 10
The factored version would be:
(x + 10)(x - 10)
Test it out:
It will expand to x^2 + 10x - 10x - 100
As you can see, the '10x' will cancel out, leaving x^2 - 100 which suggests it is correct
