Answer:
The y-intercept of the graphed function is (0,-9)
Step-by-step explanation:
The y-intercept of the graphed function is (0,-9) because the y-intercept is where the point where the line meets with the y-axis, and the point where the line meets with the y axis is (0,-9)
Therefore the answer is
(0,-9)
I hope this helped you.
Answer:
Just do -6 - 6×3 and you'll get -24
Answer:
0.78
Step-by-step explanation:
We have the next probability distribution:
X P(X)
0 0.2
1 0.3
2 0.5
As we can see when we add all the probabilites the result is 1. Now calculating the mean we have:
The standard deviation is:
Then using the data that we have:
Then the standard deviation is 0.78
Hi there.
Thanks for using Brainly!
First, let's rewrite to make this problem easier.
1^2 - a^2b^2
Then we must multiply the terms with equal exponents with their bases.
1^2-(ab)^2
Using the factor: a^2 - b^2=(a-b)(a+b)
We can factor using that expression.
(1-ab) x (1+ab)
After factoring, this has been our solution.
Solution: (1-ab) x (1+ab)
