An amusement park ride rotates around a fixed axis such that the angular position of a point on the ride follows the equation: θ
pshichka [43]
I found a missing question online. <span>What is the magnitude of the angular displacement of the ride in radians between times t=0 and t= t1?
We can imagine our ride traveling from the starting point A to some point B (at t=1s).
We can find the angle of both points, and when we subtract them we get angular displacement.
</span>A: \theta(0)=a\\&#10;B: \theta(1)=a+b(1)^2-c(1)^3=a+b-c
<span>Our angular displacement is:
</span>\Delta\theta=\theta(1)-\theta(0)=a+b-c-a=b-c=0.85-0.035=0.815 rad<span>

Find the probability of each event. A class has five boys and nine girls. If the teacher randomly picks six students, what is th
kumpel [21]

Answer: \dfrac{60}{143}

Step-by-step explanation:

Given,  A class has five boys and nine girls.

Total students = 5+9=14

Number of ways to choose 6 students out of 14= ^{14}C_6  [Using combinations]

Number of ways to choose 4 girls out of 6 (4 girls + 2 boys = 6 ) = ^{9}C_4\times\ ^{5}C_2

If the teacher randomly picks six students, then the probability that he will pick exactly four girls:-

\dfrac{^{9}C_4\times \ ^{5}C_2}{^{14}C_6}

=\dfrac{\dfrac{9!}{4!5!}\times\dfrac{5!}{2!3!}}{\dfrac{14!}{6!8!}}\\\\=\dfrac{1260}{3003}\\\\=\dfrac{60}{143}

hence, the required probability = \dfrac{60}{143} .
