There are 24 possible answers, 6 are correct answers and 18 are incorrect answers. By use of the hypergeometric distribution the probabilities of each possible number of randomly selected correct answers can be found, as follows:
P(0) = 0.1379, P(1) = 0.3819, P(2) = 0.341, P(3) = 0.1213, P(4) = 0.017, P(5) = 0.0008, P(6) = 0.000007.
The expected or mean number of correct answers is found from:
The answer is: 1.4998
Answer:
-1 3/4 =x
Step-by-step explanation:
-3 1/2= 1/2x+1/2x+x
Combine like terms
-3 1/2 = 2x
Change to an improper fraction
- ( 2*3+1)/2 = 2x
-7/2 = 2x
Multiply each side by 1/2
-7/2 *1/2 = 2x* 1/2
-7/4 = x
Changing to a mixed number
-4/4 -3/4 =x
-1 3/4 =x
Answer: linear
Step-by-step explanation: cus when u connect the points it forms a straight line
S is 3 parts of R, or 9. 9 is 3/4 of 12, so R is 12. 12 plus 9 is 21, which is half of the full area of the rectangle. The area of the rectangle is 42 square centimeters. Now, we need to find what R is to the whole rectangle. We know that R is 12 square centimeters, and that the rectangle is 42 square centimeters. That ratio is 12 to 42. If it is simplified, that would be 6 to 21. If it is simplified further, you find that it is 2 to 7. Hope this wasn't too confusing, and I hope that I helped :)
