Ugo [173]

Answer:

4

Step-by-step explanation:

There are 4 board members and 3 committee members. You can solve this using combinations:

4C3 = 4!/(3!(4-3)!) = 4!/(3!1!) = 4

You can also solve this by recognizing that since there is one fewer committee spot than there are board members, there will be one possible committee excluding each of the 4 board members.

Pls see attached question
zimovet [89]

Answer:

Step-by-step explanation:

put it on a coorinate grid,

circle circumference = 2*pi*r = 100.53

so the arc 19.2/100.53 = about 0.15 times the circumference of the circle

0.15*2pi = angle AOB in radians = 0.97

length DE is like 7.44

angle DOE is approx 0.485 radians beacuse it's half of angle AOB

area of shaded region is 804.2477 probably. I'm not sure about this last one sorry I think my calculator messed up
