A 12-sided die is rolled. The set of equally likely outcomes is {1,2,3,4,5,6,7,8,9,10,11,12}. Find the probability of rolling a
Vesnalui [34]
Answer:
1/12
Step-by-step explanation:
There are 12 equally likely outcomes. 1 of the outcomes is a 2. So the probability is 1/12.

Answer: 1064 square meters
Step-by-step explanation: area of a triangle is a= 1/2xhxw a=1/2xhx28
h= 76 (90-14)
a=1/2x76x28=1064
Answer:
x = -3/2
Step-by-step explanation:
4x² + 12x + 9 = 0
Use AC method to factor, or recognize the perfect square.
(2x + 3)² = 0
2x + 3 = 0
x = -3/2
The cofunction of cos is sin(90-x)
90 degrees is equal to PI/2
The cofunction becomes sin(PI/2 - 2PI/9)
Rewrite both fractions to have a common denominator:
PI/2 = 9PI/18
2PI/9 = 4PI/18
Now you have sin(9PI/18 - 4PI/18)
Simplify:
Sin(5PI/18)
