Answer:
OD.0
Step-by-step explanation:
because 2(X+4)-1 = 2x+7
or, 2x+8-1 = 2x+7
or, 2x+7= 2x+7
and it cancels out eachother so it will be 0
Answer:
60%
Step-by-step explanation:
3 of the 5 elements in P are odd (5, 11, & 13), so the probability is 3/5 or 60% or 0.6. (Depending on the format your teacher wants it in).

12) 4 times right, 4 up
13) 1 time left, 1 down
14) 2 times left, 2 up
Answer:
Points A and C are on the unit circle
Step-by-step explanation:
The unit circle is a circle of radius 1, that is, all the points that are inside the circle have the sum of the squares of its coordinates that are at most 1. Here, we have to test this for each option.
In options B and D, the coordinates 13/7 and 4/3, respectively, means that this sum will be larger than 1, and this points will not be on the unit circle. Now we text for options A and C.
A. ( 5/13, 12/13)

Since the sum of the squares is 1, the point is on the unit circle.
C. (1/3, 2/3)

Since the sum of the squares is less than 1, the point is on the unit circle.
Answer: The sample space is {1, 2, 3, 4, 5, 6}.
The expected value for the game is 0.
The game is fair because the expected value is equal to 0.
Step-by-step explanation:
For rolling a dice the sample space = {1, 2, 3, 4, 5, 6}
As there are equal number of odd numbers as well as even numbers and we get one point if we roll an even number and negative one point if you roll an odd number, therefore, the expected value = 0
Therefore, the game is fair because the expected value is equal to 0.
