Answer:
Option D
Step-by-step explanation:
Probability is the likelihood or chance of an event occurring.
Probability = the number of ways of achieving success
/the total number of possible outcomes
For example, the probability of flipping a coin and it being heads is ½, because there is 1 way of getting a head and the total number of possible outcomes is 2 (a head or tail). We write P(heads) = ½ .
The probability of something which is certain to happen is 1.
The probability of something which is impossible to happen is 0.
The probability of something not happening is 1 minus the probability that it will happen.
By definition we can see that probability lies between 0 and 1 only both inclusive
Hence option D is right.
Answer:
Step-by-step explanation:
(1+√3)(2-√3)=1(2-√3)+√3(2-√3)
=2-√3+2√3-3
=-1+√3
1) width = x
length = x + 8
perimeter = 2 (length + width)
196 = 2 * (x+8+x)
196 = 2* (2x+8)
196 = 4x + 16
180 = 4x
x = 45 (thats width)
2) length would be 45+8=53
3) area = length times width = 45 * 53 = 2385 square feet
Okay, so in order to find out how much time it takes to travel 529 miles given a certain time, you will need to divide. So options B and C are immediately out. You will need to divide the miles by the speed, so that your units end up cancelling out, leaving you with an actual measurement of time as your units. So option A is your answer.
