Answer:
1:1 or one red circle to one blue circle
There is one red and one blue circle
If order mattered, then there would be 6*5*4*3 = 30*12 = 360 different ways to form the committee. However, no single member outranks the other. Each member has equal ranking. So order does not matter.
Since order does not matter, we must consider all of the ways to arrange a single group of 4 people. That is 4! = 4*3*2*1 = 24 ways. We overcount by a factor of 24 when order doesn't matter which is why we divide the previous result (360) by 24 to get 360/24 = 15
Answer: 15
Note: you can use the combination formula n C r = (n!)/(r!*(n-r)!) with n = 6 and r = 4 to get the same answer
I think it would be a 1 in 6 chance for 1 time so I would assume for 2 times it would be a 2 in 12 chance (1/6, 2/12)
Answer:
16 rides
Step-by-step explanation:
Option 1 . Admission fee = $10
Each ride = $0.50
Option 2 . Admission fee = $6
Each ride = $0.75
Let no. of rides be x
So, cost of ride according to option 1 = 0.50x
So, total cost after having x rides according to option 1 :
= 10+0.50x ---1
Cost of ride according to option 2 = 0.75x
So, total cost after having x rides according to option 2 :
= 6+0.75x --2
Now to find the beak even point i.e. having the same cost
Equate 1 and 2





Thus for 16 rides , the two options have the same cost .
Hence the break even point is 16 rides
Answer:
130.24
Step-by-step explanation:
8*10+3.14*4^2=
80+50.24=130.24 ft^2
Cut the shape into a semi-circle and rectangle (with length 10 and width 8).
You'll find the radius of the semi-circle is 4.
The area of the rectangle is 80.
Then use the pir^2 formula but replace pi with 3.14
3.14 multiplied by radius 4 squared is 50.24
50.24 plus 80 is 130.24 ft squared.
