Answer: there aren't any x intercepts.
Step-by-step explanation:
The function doesn't touch the x-axis only the y-axis giving that there aren't any x intercepts. The y intercepts is (0,5).
Answer: -1.1 , 2.4 , 1.51
Step-by-step explanation:
Answer:
For X, the parameter
is λX = 1/2 and for Y it is λY = 1. Using the formula sheet, Mean is
E[Z] = E[X] + 2E[Y ] = 4. Variance is V ar(Z) = V ar(X) + 4V ar(Y ) = 8.
Hey there! I'm happy to help!
To find the surface area of a sphere, here is what you do.
You square the radius.
4²=16
You multiply by 4.
16×4=64
And you multiply by pi!
64×π=64π
Therefore, the surface area of the sphere is A. 64π units². It's that easy!
Now you can find the surface area of a sphere! Have a wonderful day! :D
You would divide 198 by 9.
198÷9=22
Each person would clean 22 rooms.
