= 100 ft./sec

As we know,

Angular velocity,

⇒  \omega=\frac{V}{R}

On substituting the values, we get

⇒     =\frac{100}{100}

Reil [10]

Answer:

a. 0.6

b. 0.5

Step-by-step explanation:

Let A be the event that student takes algebra and C be the event that student takes Calculus 3.

P(A)=0.60

P(C)=0.5

P(A and C)=0.30

a.

We have to find P(A/C).

P(A/C)=P(A and C)/P(C)=0.3/0.5=0.6

Thus, if someone took ​Calculus 3, the probability that he/she took ​Linear Algebra ​ too is 0.6 or 60%

b.

We have to find P(C/A)

P(C/A)=P(A and C)/P(A)=0.3/0.6=0.5

Thus, if someone took ​Linear Algebra, ​the probability that he/she took ​Calculus 3 ​ too is 0.5 or 50%
