If you know how to use built-in statistical functions on a calculator such as the TI-83 or 84, you can solve this problem with one press of the ENTER key on the calculator:
normalcdf(-100, 400, 504, 111) = 0.17 (answer)
Otherwise, find the z-score associated with 400:
400-504
z= ------------- , and the use a z-score table to find the area under the
111 standard normal curve to the left of this z value.
Answer with Step-by-step explanation:
We are given that a ball is thrown into the air with velocity
Height after t seconds is given by
We have to find the average velocity for the ball during the time [1,2].
We know that average velocity=
Average velocity=v=
Substitute t=1 then we get
Average velocity=
Substitute t=2 then
Average velocity=
Average velocity[/tex]=-24 m/s[/tex]

Step-by-step explanation:
Hello, we need first to develop and then identify the like terms.
So a = 28.
Thank you
40 * 20% is 8.
In total, 48, if you add them up.
Hope this helped,
