The diameter of the plate is 12, and the formula for finding circumference is diameter times pie. so you multiply pie (or 3.14 if you aren't using a calculator) times 12 and it should give you 37.6991. rounded to the nearest tenth, that's 37.7, hope I helped!

A single fair die is rolled. What if event A stays the same, i.e., A={2,4} but B={2,4,5}. Event A is independent with event B. T
den301095 [7]

Answer:

False.

Event A and event B are not independent.

Step-by-step explanation:

We know that event A and event B are

A= {2,4} and B= {2,4,5}.

If the following condition satisfies then event A and event B are independent:

P( A and B)= P(A)*P(B).

Now A and B=?

A and B=A∩B= {2,4} ∩ {2,4,5}

A and B=A∩B={2,4}

The single fair die results in 6 outcomes so, the sample space will contain 6 elements.

Thus,

P(A∩B)=2/6=1/3

P(A)=2/6=1/3

P(B)=3/6=1/2

P(A)*P(B)=1/3*1/2=1/6

As,

P(A∩B)≠P(A)*P(B)

1/3≠1/6

Thus, events A and event B are dependent.

Zinaida [17]

Answer:costC(p)= 1400+20p

R(p)= 4p^2+200p

Profit= 4p^2+ 180p-1400

Step-by-step explanation:

q=4p+200

Student council charge $400 per week.

Revenue= price × quantity.

Relationship between revenue and profit= Revenue-total cost.

Total cost= cost of facilities +(cost of one shirt)× number of T-shirts sold per week.

C(p)= 400 + 5(q)

Put q=4p+200

C(p)= 400 + 5 (4p +200)

C(p)= 400+ 20p + 1000

C(p)= 1400+ 20p

Relationship between revenue and price=Revenue= price × quantity

R(p)= p×q

Put q=4p +200

R(p)= p ×(4p +200)

R(p)= 4p^2+ 200p

Profit= Revenue - total cos

Profit=R(p) -C(p)

Profit= (4p^2 + 200p) - ( 20p +1400)

Profit= 4p^2 + 180p -1400
