Solution:-
The trajectory of a rocket launched is modeled by a parabolic path via a quadratic equation as follows:
Where,
y: The height of the rocket from ground
x: The time taken since rocket launch
We are to determine the time ( x ) it takes for the rocket to hit the ground. This can be determined by setting the quantity ( y ) to zero as follows
solve the quadratic equation using quadratic formula as follows:
Answer: Ignore the negative value for time " -0.375 ". Hence, the rocket hits the ground at time t = 17 seconds
Answer: 0.9738
Step-by-step explanation:
We assume that the scores follows a normal distribution.
Let denotes the class average .
As per given we have,
Sample size : n= 12
The probability that a class of 15 students will have a class average greater than 70 on Professor Elderman’s final exam will be :
Hence, the correct answer = 0.9738
