Given:
15 students
2 students must be chosen.
No repetition, no order
This is a combinations problem. We use this formula: n! / (n-r)!(r!)
n = 15 ; r = 2
15! / (15-2)!(r!) ⇒ 15! / 13! * 2! = 105
Answer:
Test Cross , 50% to 50%
Step-by-step explanation:
just took the test yw
Y result from something being multiplied by X , and the values are always proportional to one another . Notice that putting these points into a ratio of x - value to Y - value result in 1:3 as a simplified version . So , The constant of proportionality is what x is being multiplied by to get y . In this case , it is 3
Step-by-step explanation:
Cost of white shirt=$15
Cost of tie-dye shirt = $20
Total number of shirts= 500
Total number of white shirts= 200
Cost of white shirts = 200×15=$ 3000
Total number of tie-dye shirts = 300
Cost of tie-dye shirts = 300×20= $6000
Verification:
3000+6000=$9000 proved!
Answer:
V = pi 36 units^3
V =113.04 units^3
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2 h
V = pi ( 2) ^2 *9
V = pi 36
Letting pi = 3.14
V =113.04
